The unit 17 can function as an operation information output unit, and the storage unit 12 can function as an operation information storage unit.

The processing unit 22 can function as a driving information acquisition unit, the storage unit 24 can function as a driving information storage unit, and the display unit 29 can function as a driving information display unit.

Next, a line-of-sight detection method using the line-of-sight detection sensor 14 and the subject photographing camera 16 of the viewpoint tracking device 10 will be described with reference to FIG.
An arrow 39 indicates the shooting direction of the subject shooting camera 16, and the camera posture axis 110 indicates a coordinate axis for determining the orientation of the viewpoint tracking device 10 used by the three-dimensional motion sensor 15. With the head direction as the C axis of the viewpoint tracking device 10 coordinate axis, the A axis and the B axis orthogonal to the C axis are set as shown. The absolute coordinate axis 120 is a rotation direction axis in which the Y axis is positive with respect to the rotation direction of the earth, the Z axis is a geomagnetic axis in which the north pole direction horizontal to the ground is positive, and the X axis is positive in the vertical direction from the ground. The coordinate axis is the height axis. At this time, the rotational displacement from the absolute coordinate axis 120 to the camera posture axis 110 is expressed as roll (κ) for the Y axis, pitch (φ) for the Z axis, and yaw (ω) for the X axis.

  The three-dimensional motion sensor 15 can include at least one of a gyro sensor, a geomagnetic sensor, a gravity sensor, and an acceleration sensor. Since the geomagnetic sensor can measure the geomagnetism parallel to the ground and detect the latitude and longitude information, the rotational displacement (κ, φ, ω) of the absolute coordinate axis 120 to the camera posture axis 110 can be detected. In addition, since the gravity sensor can know from which direction the gravity is applied with respect to the viewpoint tracking device 10, a plurality of gravity sensors are installed in the viewpoint tracking device 10 and compared with each other by detecting the absolute values of the gravity tracking device 10 as in the geomagnetic sensor. The rotational displacement (κ, φ, ω) of the coordinate axis 120 to the camera posture axis can be detected.

  The gyro sensor is provided with a gyro sensor on each of the A, B, and C axes. This is because the viewpoint tracking device 10 may rotate at a speed faster than the sensing time of the geomagnetic sensor and the gravity sensor, and therefore the rotational displacement (κ, φ, ω) detected by the geomagnetic sensor and the gravity sensor is used as the gyro reference rotational displacement ( This is because a further gyro rotational displacement (κ1, φ1, ω1) from the reference rotational displacement is calculated by the gyro sensor as κ0, φ0, ω0).

  As a specific sensor installation example, by installing a geomagnetic sensor or a gravity sensor so as to be paired with gyros installed in the directions of the A, B, and C axes, detection of a reference point, The rotation operation can be detected, and the position and orientation of the viewpoint tracking device 10 can be detected. Furthermore, when an acceleration sensor is installed and the acceleration of the viewpoint tracking device 10 is detected so that a quick movement is detected by the acceleration sensor, the gyro rotational displacement (κ1, φ1, ω1) is the gyro reference of the gravity sensor or the magnetic sensor. When the rotational displacement (κ0, φ0, ω0) is corrected and a slow movement is detected, the gravitational sensor or magnetic sensor corrects the gyro-reference rotational displacement (κ0, φ0, ω0) for more accuracy. Thus, the rotational displacement (κ, φ, ω) of the viewpoint tracking device 10 can be measured in real time.

  Further, the viewpoint tracking device 10 uses the processing unit 11 to detect latitude and longitude information from the geomagnetic sensor of the three-dimensional motion sensor 15 and / or the GPS, and the camera projection center coordinates O (Xo, Yo) of the viewpoint tracking device 10. , Zo) can be detected dynamically. When the place where the viewpoint tracking device 10 is used is fixed and determined, the camera projection center coordinates O (Xo, Yo, Zo) may be manually input. This manual input is input, for example, as setting data of the camera projection center coordinates O of the program for controlling the viewpoint tracking device 10 stored in the storage unit 12 by the input unit 28 of the driving information management device 20, and from the communication unit 26 to the communication unit 18. Is performed by being stored in the storage unit 12.

In this way, the camera projection center coordinates O (Xo, Yo, Zo) and the rotational displacement (κ, φ, ω) of the viewpoint tracking device 10 are obtained using the three-dimensional motion sensor 15. The subject position p1 on the field image determined by the rotational displacement (κ, φ, ω) of the camera projection center coordinates O (Xo, Yo, Zo) is determined by the angle of view determined by the focal length of the lens of the subject photographing camera 16. It is possible to determine the position P1 (X1, Y1, Z1) of the subject on the absolute coordinates from xp1, xp1).
Furthermore, as described above, since the position of the point of interest on the subject is known using the line-of-sight detection sensor 14, the point of interest p2 (xp2, yp2) on the visual field image in the shooting direction of the line-of-sight detection sensor 14 is used. The position P2 (X2, Y2, Z2) on the absolute coordinate of the gazing point can also be determined.

  Therefore, by storing the device information to be operated together with the position information in the storage unit 12 or the storage unit 24 in advance, the processing unit 11 or the processing unit 22 can store the device information existing in the visual field image 38 of the worker 1. It is possible to obtain. Referring to the example of FIG. 3, whether the worker 1 is viewing the equipment state monitoring screen A (41a) or the equipment state monitoring screen B (41b) is determined by the camera projection center coordinates O (Xo, Yo, Zo). ) Can be determined by the absolute coordinate position P1 (X1, Y1, Z1) related to the position p1 (xp1, xp2) of the subject moving to the field image determined by the rotational displacement (κ, φ, ω). Which part of the state monitoring screen A (41a) is viewed can be determined by the position P2 (X2, Y2, Z2) on the absolute coordinates related to the gazing point position p2 (xp2, yp2). Therefore, since the position displayed at the position of the point of gaze is known, the work object placed at that position is also found, and the processing unit 11 or the processing unit 22 can acquire driving information related to the work object. And the driving | operation information relevant to a work target object can be audio | voice-output via the audio | voice output part 17, and it can notify the operator 1 and can ensure the technical management regarding an apparatus.

  With reference to FIG. 4, a processing flow when performing the technical management method in the rolling process will be described. This process is executed using the viewpoint tracking device 10 and the driving information management device 20. In this embodiment, the operator wears the viewpoint tracking device 10 on the head in order to manage the quality of his / her work, and the center in a factory such as an ironworks, refinery, power plant, product assembly plant, etc. Work shall be performed via the equipment status monitoring screen installed in the processing device and the like and, if necessary, the operation panel.

  First, the operator monitors any of the equipment state monitoring screens 41a and 41b shown in FIG. 5 for equipment operation and monitoring. The equipment state monitoring screen 41a shows an image obtained by photographing the steel plate 51a, the guide 52, and the press machine 53 from the upper surface in the sizing press process of the rolling process. The equipment state monitoring screen 41b shows an image taken from the side of the steel plate 51b and the rough rolling device 54 in the rough rolling process of the rolling process. The operator monitors the equipment state monitoring screens 41a and 41b, the head of the worker moves, and the visual field image 38a taken by the subject photographing camera 16 of the viewpoint tracking device 10 is determined. The gazing point 37a is determined by applying a line of sight to the upper work object (in the example of FIG. 5, the location where the steel plate 51a moves to the press machine 53 in the sizing press process).

  Returning to FIG. 4, the subject photographing camera 16 acquires a visual field image 38 a in accordance with the movement of the worker's head (step 101), and the line-of-sight detection sensor 14 tracks the gaze point of the worker's worker. Then, the operator's gaze point 37a on the visual field image is acquired (step 102). Next, the three-dimensional motion sensor 15 determines the position P1 on the absolute coordinate of the subject on the visual field image by determining the position O (Xo, Yo, Zo) on the absolute coordinate and the orientation of the operator's head. (X1, Y1, Z1) is acquired, and the position P2 (X2, Y2, Z2) on the absolute coordinate of the gazing point is acquired (step 103). The viewpoint tracking device 10 transmits the view image, the gazing point, and the position information of the gazing point to the driving information management device 20 via the communication unit 18 (step 104), and the driving information management device 20 The information is received via the communication unit 26 (step 105).

  The operation information necessary for technical management of the sizing press process will be described with reference to FIG. FIG. 4A is a schematic top view of the steel plate 51a, the guide 52, and the press machine 53 in the sizing press process. A steel plate 51 a shown in FIG. 1A shows a state before being pressed by the press machine 53. In FIG. 2B, the steel plate 51a is moved between the press devices 53 by moving a roller below the steel plate 51a (not shown) by an operator's instruction via the control panel, for example, and is fixed by the guide 52. FIG. 6 is a schematic top view showing a state in which the steel plate 51a is pressed by the press device 53 after being pressed. FIG. (C) is a schematic top view showing a state in which the steel plate 51 a has collided with the press machine 53.

For example, as shown in FIG. 1A, an ironworks operator is in a state where the press machine 53 is opened before the steel plate 51a enters the press machine 53, and the steel plate 51a moves. It is necessary to confirm that the press machine 53 does not collide. However, if it is confirmed that the press device 53 is in the open state and the press device 53 is not in the open state, a collision state as shown in FIG. 5C occurs, which causes damage to the steel plate 51a and the press device 53.
As described above, in the technical management of the sizing press process, before the steel plate 51a enters between the press devices 53, it is confirmed that the press device 53 is open as shown in FIG. Is important information in terms of technical management, and is an example of technical skills that should be passed on to each worker.

  Returning again to FIG. 4, the operation information management device 20 obtains the acquired position information of the gazing point and the position information of the gazing position of the past excellent engineer of the sizing press process stored in the storage unit 24. The comparison (step 106), specifically, the distance between the gazing points is calculated. In the present embodiment, the work process performed by the operator is input via the input unit 28 of the driving information management device 20 and stored in the storage unit 24. Therefore, based on the information, The location information of the gaze points of the past excellent engineers is selected. Further, in the comparison process of the gazing point, in order to synchronize the time information of the gazing point of the worker and the gazing point of the excellent engineer in the past, the timing chart of the selected work process is stored in the storage unit 24. The point of interest is synchronized according to the timing chart. In addition, based on the information on the process performed by the worker stored in the storage unit 24, it is synchronized with the status monitoring information of the press machine that is the work target (monitoring information of the control machine that performs monitoring control of the press machine). (Specifically, the operation information management device 20 receives status monitoring information that the steel plate 51a is disposed in front of the press device 53 from the control device of the press device 53 via the communication unit). The viewpoint comparison process may be synchronized.

  Next, driving information is acquired from the storage unit 24 (step 107). Further, when the distance between the gazing points calculated in step 106 is larger than a predetermined value (in this embodiment, the monitoring target is monitored such as when the gazing point of the operator is away from the press portion of the press machine 53). In this case, the operation information is obtained from the storage unit 24, and information that is the reason why the excellent worker in the past has placed the gazing point (for example, the excellent worker always indicates that the “steel plate 51a is the press machine 53”). Before entering the period, “confirming that the press machine 53 is open” is added to the operation information. Further, when the gazing point comparison distance exceeds the reference value, an abnormality warning (a warning for avoiding the state shown in FIG. 6C described above) may be included in the driving information.

  Next, the driving information management device 20 transmits driving information via the communication unit 26 (step 108), the viewpoint tracking device 10 receives driving information via the communication unit 18 (step 109), and then Then, the operation information and / or abnormality warning audio data is output to the worker 1 via the voice output unit 17 (step 110) (for example, a past excellent worker as described above places a point of sight The information that is the reason why the press device 53 is open before the steel plate 51a enters between the press devices 53 is output).

  In this way, since the driving information for the object watched by the worker is output to the worker by voice, the worker considers the mistake in the work as shown in FIG. 4C by confirming the driving information, Before the steel plate 51a moves, it is possible to check the open state of the press machine 53 and take appropriate measures.

  In step 111, the visual field information, the gazing point, and the driving information acquired during the work of the worker may be displayed in comparison with the driving information that has been stored by the past excellent workers. Is possible.

FIG. 7 is a diagram showing an equipment state monitoring screen showing a comparison of operation information of the sizing press process displayed on the display unit 29 of the operation information management device 20.
FIG. (A) is a diagram showing a movement of a gazing point in a sizing press process performed by an excellent worker in the past. FIG. (B) is a diagram showing the movement of the gazing point in the sizing press process performed by an operator with insufficient experience.
The gazing point 37a-1 shown in the figure (a) is positioned so that an excellent worker can confirm that the press machine is open before the steel plate 51a-1 is pressed by the press 53a. . On the other hand, the gazing point 37b-1 shown in FIG. 4 (b) confirms that an inexperienced operator confirms that the press machine is open before the steel plate 51b-1 is pressed by the press 53b. Therefore, it is positioned at a place different from the gaze point 37a-1 of an excellent worker.

Furthermore, in addition to the visual field image and the gazing point, the operation information stored in the storage unit 24 is displayed on 38a-2 and 38b-2 of the equipment state monitoring screens 38a and 38b. And in the operation information 38a-2, 38b-2, since a comment such as “confirming the open state of the press machine” is described, an operator with insufficient experience confirms this comment, so This makes it possible to clearly determine the reason for differences in the attention points of various workers.
And the technical management process of a rolling process is complete | finished.

  Since it is difficult for the worker to grasp where his / her operation management level is, the visual field image and the gazing point of the past worker stored in the storage unit 24 can be used for the advanced, intermediate, and beginners. It is possible to determine their own level based on the comparison display described in step 111. Moreover, standard management can be easily performed by storing a visual field image, a gazing point, driving information, etc. (especially reasons for attention point placement) for each level, such as advanced, intermediate, and beginner.

  As described above, the operation management method using the viewpoint tracking device 10 and the operation information management device 20 has various work target devices and equipment state monitoring screens. It is possible to check whether there is no problem compared to what, and to manage from the operational / quality / safety aspect whether it is engaged in work.

  As described above, the driving management method using the viewpoint tracking device 10 and the driving information management device 20 does not create and update simulation data as in the prior art, and uses the shooting range actually shot by the camera to manage driving. And learning with work can be promoted efficiently by comparing with excellent driving information in the past.
