Description

Construction site performance evaluation system, method and program

The present invention relates to a factory site performance evaluation system, method, and program for confirming and evaluating the progress of construction, and more specifically, to a system for performing performance evaluation on each work day.

In recent years, technology that makes the construction site more efficient with IoT (Internet of Things) has been receiving attention. For example, as shown in Patent Document 1 below, a work group of a contractor carries a terminal device and sends/receives output information to and from a management device of a specialized contractor at any time so that the progress status can be confirmed at any time. There is a technology that saves labor by automating monthly volume calculation.

Specifically, a portable terminal, a server, and a data group such as image data representing a blueprint are read from the server to create a delivery file, which is sent to the portable terminal of the work group and registered in the portable terminal. The portable terminal has a slave database that stores data groups, and has a line segment different from the design drawing or an area surrounded by line segments on the screen. While displaying the construction location, it is configured to transmit the registered output information by touch operation to the output management device.

The construction site image 16A is an image of the construction site 50 taken aerial by the imaging device 42 (camera or the like) mounted on the drone 40. The three-dimensional data 16B is obtained by processing the construction site image 16A into three-dimensional data. The three-dimensional processing is performed by a technique such as SfM (Structure from Motion). The construction site image 16A and the three-dimensional data 16B are all stored in the storage 16 during the construction period.

The design drawing 16C is a design drawing of the construction site 50 and is three-dimensional data. The work record 16D is a work record of each work site worker 60 on the construction site 50. Such a work record 16D is acquired from a wearable terminal, a camera, a process chart, or the like used by the site worker 60.

The communication unit 18 is used when acquiring the construction site image 16A from the imaging means 42 of the drone 40 or giving a work instruction to the terminal 62 of the site worker 60 via the network. The communication unit 18 is also used when acquiring a work record from the terminal 62 or the like of the site worker 60.

<Functional configuration of server>... Next, the functional configuration of the server 10 will be described with reference to FIG. The server 10 includes an image acquisition unit 20, a work record acquisition unit 22, a processing unit 24, a first extraction unit 26, a second extraction unit 28, an evaluation unit 30, a work instruction unit 32, and a specification unit 34. And providing means 36 and advice means 38.

The image acquisition unit 20 acquires, via the communication unit 18, an image of the construction site 50 on the day of the work, which is aerial photographed by the imaging device 42 of the drone 40. The acquired construction site image 16A is stored in the storage 16 of the server 10. Note that the image of the construction site 50 is not limited to be acquired once a day, but may be acquired every predetermined time (for example, every 30 minutes or every hour).

The work record acquisition unit 22 acquires a work record for each worker, and specifically, acquires the work record from the wearable terminal of the site worker 60, the camera, the process chart, and the like. The acquired work record 16D is stored in the storage 16 of the server 10.

The processing means 24 processes the construction site image 16A of the work day acquired by the image acquisition means 20 into three-dimensional data. The three-dimensional processing is performed by a technique such as SfM (Structure from Motion). The three-dimensional data 16B is stored in the storage 16 of the server 10.

The first extraction means 26 extracts the difference between the three-dimensional data 16B and the design drawing 16C of the construction site 50. The second extraction means 28 extracts the difference between the three-dimensional data on the day of work and the three-dimensional data before the day before work.

The evaluation means 30 evaluates the production amount on the work day according to the difference between the three-dimensional data based on the work site image on the work day extracted by the first extraction means 26 and the design drawing 16C of the construction site. ..

The work instruction means 32 gives a work instruction for tomorrow or later to the site worker 60 in accordance with the evaluation by the evaluation means 30. For example, a work instruction is sent to the terminal 62 of the site worker 60 via the communication unit 18. Alternatively, when the server 62 is accessed from the terminal 62, a work instruction for tomorrow or later may be displayed on the terminal 62.

The identifying means 34 identifies a dangerous point in the construction site 50 according to the difference between the three-dimensional data of the work day extracted by the second extracting means 28 and the three-dimensional data before the day before the work. For example, the identifying unit 34 identifies a slope, a presence or absence of a dangerous material, or a dangerous place with a high possibility of landslide in the construction site 50 according to the extracted difference.

The providing unit 36 provides the on-site worker 60 with the dangerous information according to the dangerous place identified by the identifying unit 34. For example, the hazard information may be provided to the terminal 62 of the site worker 60, or the information may be provided in another form.

The advice means 38 gives advice on interruption or review of construction in accordance with the danger information. The advice may be given to the supervisor of the construction site 50, or may be given to each worker as needed. The advice itself may be provided to the terminals of the supervisor or the worker, or the advice may be viewed when the supervisor or the worker accesses the server 10.

<Basic construction site performance evaluation process>... Next, the basic construction site performance evaluation process will be described with reference to FIG. FIG. 4 is a flowchart showing an example of the basic processing of construction site performance evaluation of this embodiment. First, the server 10 uses the image acquisition unit 20 to acquire an image of the construction site 50 on the day of the work, which was taken by the imaging device 42 of the drone 40 (step S10). The acquired image is stored in the storage 16 as a construction site image 16A.

Next, the processing means 24 processes the acquired construction site image 16A into three-dimensional data (step S12). The processing on the three-dimensional data is performed by, for example, SfM (Structure from Motion). The processed three-dimensional data is stored in the storage 16 as the three-dimensional data 16B. Then, the first extracting means 26 extracts the difference between the three-dimensional data 16B on the work day and the design drawing 16C on the construction site (step S14).

The evaluation means 30 evaluates the work volume on the work day from the difference between the three-dimensional data 16B on the work day extracted by the first extraction means 26 and the design drawing 16C of the construction site 50 (step S16).

Then, the work instruction means 32 gives a work instruction for tomorrow to the site worker 60 according to the evaluation. The work instruction may be sent to the terminal 62 of the site worker 60, or may be in another form.

In this way, the construction site image 16A taken aerial on the day of work is processed into three-dimensional data 16B, and it is decided to evaluate the output on the day of work from the difference from the design drawing 16C. There will be no significant deviation from the drawing. Further, by issuing work instructions for tomorrow or later to the site worker 60 according to the evaluation, feedback of the output evaluation is effectively performed.

In step S10 described above, the image acquisition unit 20 acquires an image of the construction site 50 every predetermined time (for example, every 30 minutes or every hour), and in step S12, the processing unit 24 causes the predetermined time. Each image may be processed into three-dimensional data. Then, in step S14, the first extracting means 26 extracts the difference between each of the three-dimensional data and the design drawing 16C of the construction site, and in step S16, the evaluating means 30 responds to each difference. Then, the output on the work day may be evaluated every predetermined time. By performing the processing at every predetermined time in this way, it is possible to evaluate the performance on the day of the work in several times in a form close to real time.

<Work instruction processing>... Next, an example of the work instruction processing will be described with reference to FIG. FIG. 5 is a flowchart showing an example of the work instruction process of this embodiment. First, the server 10 acquires the work record of each worker by the work record acquisition means 22 (step S20). The work record for each worker can be acquired from the wearable terminal, camera, process chart, or the like of the site worker 60. The acquired work record is stored in the storage 16 as a work record 16D for each worker.

Next, the evaluation means 30 evaluates the amount of work on the day of work for each site worker from the work record 16D (step S22). Then, the work instructing means 32 gives work instructions for tomorrow after tomorrow for each field worker in accordance with the evaluation of the work volume of each field worker on the work day (step S24). The work instruction is given through the terminal 62 of the site worker 60, for example.

In this way, it is possible to more appropriately perform construction according to the design drawings by evaluating the work volume on the day of work for each site worker and giving work instructions for the person in charge after tomorrow.

<Dangerous place identification processing> Next, an example of the dangerous place identification processing will be described with reference to FIG. FIG. 6 is a flowchart showing an example of the dangerous place identifying process of the present embodiment. First, the second extracting means 28 extracts the difference between the three-dimensional data on the day of work and the three-dimensional data before the day before work (step S30).

Then, the specifying unit 34 specifies a dangerous point in the construction site 50 according to the difference extracted by the second extracting unit 28 (step S32). Then, the providing unit 36 provides the worker with the danger information corresponding to the dangerous place (step S34). In addition, the advice unit 38 gives advice on interruption or review of construction according to the danger information (step S36).

In the identification of the dangerous place in step S32, the identifying unit 34 identifies, as the dangerous place, an inclination in the construction site 50, the presence or absence of a dangerous material, or a portion having a high possibility of a landslide according to the difference. You may The provision of the danger information to the on-site worker 60 and the advice of interruption or review of the construction may be performed through the terminal 62 of the on-site worker 60, or may be performed by other means.

In this way, the danger point is identified from the difference between the 3D data on the day of work and the 3D data before the day before work, and the danger information according to the danger point and advice for interruption or review of construction are advised. Therefore, it is possible to proceed with the construction safely, or to suspend or review the construction if necessary.

<Effect>... According to the above-described embodiment, the server 10 acquires the image of the construction site on the day of the work, which is taken by the image capturing means 42 of the drone 40, and processes it into the three-dimensional data 16B. The difference between the data 16B and the design drawing 16C of the construction site 50 is extracted to evaluate the output on the day of work. For this reason, it is possible to evaluate the performance on the day of work from the difference between the work actually performed and the design drawing laboratory on a work day basis rather than on a work month basis. In addition, by evaluating the output on a work day basis, there will be no significant deviation from the design drawings when the construction is completed.

Note that the above-described embodiment is an example, and can be changed as appropriate within the range of achieving the same effect. Further, the present invention may be provided as a program executed by the server 10. This program may be provided in a state of being recorded in a computer-readable recording medium, or may be downloaded via a network. The present invention may also be provided as a method invention.

According to the present invention, an image of a construction site on the day of aerial shooting with a drone is acquired and processed into three-dimensional data, and the difference between the three-dimensional data and the design drawing of the construction site is extracted to determine the performance on the day of the work. By evaluating the above, it is possible to evaluate the work volume on the work day on the basis of the difference between the work actually performed and the design drawing on a work day basis, so it is suitable as a system for performing work volume evaluation on each work day at the construction site. ..
