Otherwise, if the similarity ratio interval is greater than or equal to the similarity ratio interval, it is determined that the user is in a dangerous posture, and the display step S5 is executed.
In step S5, when the similar proportion compared by the comparison module 14 is within the similar proportion range, in the embodiment, the display 15 displays the comparison information (not shown) if it is determined that the user is in the dangerous posture.

Further, as shown in fig. 7, the operation unit 13 calculates the stereoscopic image information 211, the stereoscopic image information 212 and the stereoscopic image information 213 of the posture of the object 2 in the measurement environment. In the present embodiment, the stereoscopic image information 211 and the stereoscopic image information 212 are not similar to the plurality of biological stereoscopic image information 22, so the comparing module 14 determines that the user is not in a dangerous posture in the comparing step S4, and returns to the transmitting step S1. Further, the similarity ratio between the stereoscopic image information 213 and the biological stereoscopic image information 22 is within the similarity ratio range set by the user, so that the comparing module 14 compares the stereoscopic image information 213 and the biological stereoscopic image information 22 with each other in the comparing step S4, determines that the user is in a dangerous posture, and then performs the displaying step S5.
Further, in the displaying step S5, the display 15 according to the first embodiment of the present invention is a smart phone, so that the display 15 displays the comparison information, which is the call for emergency service.
Therefore, it can be further understood from the above description that the optical image comparison system 1 provided by the present invention, in combination with the comparison method thereof, can rapidly obtain the plurality of stereoscopic image information 21 of the user, identify whether the plurality of stereoscopic image information 21 are in a dangerous posture or in an injured state, and can send out a warning message in real time to remind the user and automatically dial an emergency service call, so that when the user has an emergency, the user can immediately perform processing and rescue, and avoid unfortunate occurrence.

Referring to fig. 9 in combination with fig. 8, fig. 9 is a flowchart illustrating a comparison method for executing an optical image comparison system according to a second embodiment of the present invention. The present invention further provides a comparing method of an optical image comparing system 1 based on the optical image comparing system 1 of the second embodiment, comprising the following steps:
the emitting step S1 'is performed by emitting the plurality of emitting lights to the test object 2 through the plurality of light emitters 11, and then performing the receiving step S2'.
The receiving step S2 'is to receive the plurality of the emitted lights reflected by the object 2 through the light receiving unit 12, calculate the flight time information of the plurality of the emitted lights according to the transmission and reflection information of the plurality of the emitted lights, and execute the calculating step S3'.
The operation step S3 'is performed by the operation unit 13 electrically connected to the light receiving unit 12 to receive the flight time information of the emitted lights, and to calculate the stereo image information 21 forming the posture of the object 2 in the measurement environment, and then performing the comparison step S4'.
In the comparing step S4', the stereoscopic image information 21 and the stereoscopic image information 22 are compared with each other through the biological stereoscopic image information 22 stored in the comparing module 14 to determine whether the comparison result is in the similar proportion range. If the similarity ratio interval is smaller than the similarity ratio interval, the user is determined not to be in a dangerous posture, and the step returns to the step transmitting step S1'. Otherwise, if the similarity ratio interval is greater than or equal to the similarity ratio interval, the user is determined to be in a dangerous posture, and the reminding step S6' is executed.
It should be further noted that, in the reminding step S6', between the comparing step S4 and the displaying step S5, when the stereoscopic image information 21 and the biological stereoscopic image information 22 are greater than or equal to the similar proportion interval, the reminding module 3 is activated and sends out the reminding information to remind the user or the caregiver of the danger of the user. If the user closes the reminding module 3 or releases the reminding information after reminding, the step is returned to the step of transmitting S1'. On the contrary, if the user does not turn off the reminding module 3 or remove the reminding message after the reminding module 3 is started and sends the reminding message, the displaying step S5' is executed.
In step S5', when the compared similarity ratio is within the similarity ratio range, the comparing module 14 determines that the user is in the dangerous posture, and the display 15 displays the comparison information.
It should be noted that although the above description is based on the comparison module 14 determining whether the user is in a dangerous posture or in an injured state, the present invention is not limited thereto, and when the comparison module 14 stores sufficient biological stereoscopic image information 22 and the analysis unit 143 is used to convert the stereoscopic image information 21 into the biological analysis information 23, the comparison unit 22 can further identify and compare the above information individually or in combination.

Specifically, according to the optical image comparison system 1 of the present invention, the plurality of biological analysis information 23 may include the skeleton, joints, muscles, skin, posture, speed, acceleration, etc. of the object, but the present invention is not limited thereto.
It should be noted that, compared to the conventional method using a planar image as the comparison information, since the planar image cannot completely represent the shape of the object to be measured, a large number of planar images must be taken to improve the accuracy of the comparison system, which results in the system requiring a large storage space and occupying a large hardware space.
Therefore, the present invention has the following implementation and technical effects:
first, based on the data transmission system 1 of the present invention, and in combination with the method provided by the present invention, the stereoscopic image information 21 of the user can be obtained quickly, and whether the stereoscopic image information 21 is in a dangerous posture or in an injured state can be identified, so that when the user has an emergency, the user can be immediately treated and rescued, and the unfortunate occurrence can be avoided.
Secondly, according to the invention, through the setting of the reminding module 3, when the compared similar proportion of the comparison module 14 is within the similar proportion range, the reminding module 3 is started and sends the reminding information to remind the user or the care giver of paying attention to the dangerous posture of the user, so that the convenience and the practicability in use are increased.
Thirdly, the stereoscopic image information 22 is converted into a plurality of biological analysis information 23 by the analysis unit 143, and when the comparison module 14 stores enough biological stereoscopic image information 22 and combines with the analysis unit 143, the applicability and accuracy of the invention are greatly increased.
