[Solution] In the construction image capture system of the present invention, shooting is prompted based on a planned shooting schedule, and the camera's display surface is equipped with means for easily adjusting the camera's position and angle to match a reference image, which is displayed simultaneously, with a real image of the object captured by the camera, so as to match the two.

Description

Technical Field

[0001] The present invention relates to a construction image capturing system for capturing a construction target object with a camera and obtaining a construction image in construction work.

Background Art

[0002] Conventionally, in construction work, in order to confirm and prove the construction state during the construction process from start to finish, a photographic image of the construction target object is obtained at a desired time point. In such a case, when the amount of construction is large, the number of photographic images to be obtained increases with the number of processes, making it difficult to grasp. Regarding the photographed photos, it becomes cumbersome to confirm at which time point, at which position, in which orientation, or at which angle the image was taken and what kind of image it is. If it takes time to confirm and the confirmation is neglected, mistakes may occur where the obtained photographic image is different or does not conform to the specifications such as the orientation. As the subsequent process progresses, confirmation becomes difficult. The operation of taking a camera shot is not difficult, but currently there are the above-mentioned drawbacks, which are time-consuming and prone to mistakes. It is desired to obtain a construction photographic image that meets the desired specifications in a means that is not cumbersome and easy to achieve the specifications. Among the conventional prior arts, Patent Documents 1 to 4 can be found as those for obtaining a photographic image of a construction target object. No document has been found that pursues the same problem as the present application. First, Patent Documents 1 and 2 are as follows. In the field of construction, construction work, etc., a technology is known that generates a virtual three-dimensional image of an object being constructed on-site and synthesizes and displays it on an image captured on-site to assist in the placement construction of the object on-site. Both Patent Document 1 and Patent Document 2 are this technology. As technical features necessary for the function of assisting in the placement construction of an object on-site, the position, angle, and orientation of the object to be placed must be guaranteed. Therefore, the technologies of both documents include a high-precision surveying device and a level as essential devices for measurement. The position of the object and its positional relationship, including the angle and orientation of the camera that captures the image, must be determined with high precision. Based on this assurance, both systems can perform the aforementioned functions as follows. In other words, when performing construction that involves moving and positioning an object, a device equipped with a surveying device and a camera based on the aforementioned positional relationship is placed at the site. A 3D image of the object to be constructed (referred to as a 3D image in Reference 1 and as a design model in Reference 2) is displayed on the display unit, and an image of the actual object captured by the camera is displayed on the same display surface. By observing the discrepancy (positional difference) between the two, the object is moved in the direction in which they align, thereby positioning the object in the desired location. Final measures such as fixing are then taken to complete the construction. Naturally, the aforementioned high-precision surveying equipment, spirit levels, and other devices are essential for realizing the functionality. The differences between Patent Document 1 and Patent Document 2 are as follows: Patent Document 1 describes a surveying device that "includes a surveying information output means, a driving means, a surveying information transmission means, an imaging means, and an image synthesis means. The surveying information output means measures the angle in the direction of the optical axis from which the sighting point is sighted and outputs it as surveying information." This indicates that the surveying device has high precision. Patent Document 2 describes using GNSS (Global Navigation Satellite System) for surveying in order to reduce the load on the surveying device described in Patent Document 1. In either case, high-precision surveying equipment is essential to realize the function of supporting the placement and construction of objects. Next, I will explain the differences from the original vow. First, the functions are different. The function of this application is to obtain photographic images of an object whose construction has already been completed as confirmation evidence of the construction. The condition of the photographs to be kept as evidence is provided as a reference image. Based on the image acquisition plan established for each process, the location of each object can be determined from drawings and other documents. Therefore, the precision required to determine the location is not necessary, unlike when surveying is required. Based on the plan, once you arrive at the site, you can recognize the object based on the reference image and think, "This is it." Furthermore, by observing the state of the reference image and the object image from the camera on the display surface, positional conditions (angle, distance, etc.) can be immediately recognized from differences in displacement, shape, size, etc. Therefore, by adjusting the camera's movement and angle in a direction that minimizes the difference between the reference image and the object image, it is possible to obtain an object image that is very close to the expected reference image. If there is no reference image, there is a risk that the acquired object image may differ from what was expected in terms of size, orientation, and the part to be viewed, but such a risk can be eliminated. The function of the present invention is to "adjust the camera's movement and angle in a direction that minimizes the difference between the reference image and the object image, since positional conditions (angle, distance, etc.) can be immediately recognized from differences in displacement, shape, size, etc." And, due to the differences in functionality, there are mainly two associated differences. Firstly, while Patent Documents 1 and 2 require high-precision surveying equipment and a spirit level, these are not necessary in this application. Secondly, while Patent Documents 1 and 2 describe moving the object to be constructed, in this application, naturally, the object to be constructed does not move, and only the movement and angle of the camera are adjusted. Next, we will discuss Patent Documents 3 and 4. Patent Document 3 relates to a construction photo logbook, and while it shares some common ground with the present application in that it involves taking construction photos and using them as evidence, the abstract states that it clarifies the content required for the construction photo logbook when creating construction design drawings, construction drawings, and schedules, and that it automatically generates the construction photo logbook simply by taking photos at the construction site. In other words, it concerns the handling of blank spaces in the logbook where photos corresponding to the plan should be placed when creating the logbook. Patent Document 4 describes a construction process management system comprising a tool that measures its own position and tool-specific work information corresponding to the work performed, and transmits both measurement information to a network via communication means; a camera that measures its own position and orientation, uses this measurement information to photograph the construction work area to be photographed, and transmits the position of the target and the captured image information to the network via communication means; and a system that warns workers if there are delays in the work by comparing this work information with construction drawings and construction process plans. Although it includes a camera as a component, it differs from the main purpose of this application. [Prior art documents] [Patent Documents]

By comparing a reference image, which is displayed simultaneously on the camera's display screen, with the actual image of the object captured by the camera, the camera's position and angle can be easily adjusted to match the reference image, thereby acquiring an image of the object according to the planned specifications and reducing errors and missed shots. Furthermore, by associating and saving real-world images with reference images, the degree of achievement in construction can also be evaluated. [Brief explanation of the drawing]

[Figure 5]This figure shows another embodiment of the process of capturing and acquiring an image of an object using the construction image capture system according to the present invention. [Figure 6] This figure shows another embodiment of the process of capturing and acquiring an image of an object using the construction image capture system according to the present invention. [Figure 7] This figure shows various embodiments of the display portion of the construction image capture system according to the present invention. [Modes for carrying out the invention]

[0017] Figure 1 shows one embodiment of the configuration of the construction image capture system according to the present invention. The construction image capture system 100 includes a control means 110, a shooting / display / notification management means 120 controlled by the control means 110, a shooting plan creation means 130, a reference image creation means 140, and a shooting means 150 including a camera 151. The system includes an image data accumulation means 170 for accumulating captured images and a display / notification means 190. It is even better to include a means 180 for creating a performance report that displays the construction results using the captured images. The control means 110 is a control computer that implements the functions of each means.

[0018] The following explains these functions in relation to construction work. Based on the already created construction schedule 10, the contractor uses the photography plan creation means 130 to create a photography plan table that displays a plan to take photographic images of the state of the construction object at desired points in each stage of the process, and this is saved as a photography plan table 121 in the photography, display, and notification management means 120. Furthermore, when creating a shooting plan using the shooting plan creation means 130, the shooting means can also be specified. In other words, 1) In the case of using a camera held by the worker, work instructions can also be sent to a mobile phone or similar device. 2) In the case of a fixed camera at the site, recording will be performed automatically according to the scheduled date and time. The camera is set up in advance with shooting conditions such as position (distance), height, orientation, and angle that will produce an image identical to the reference image. 3) When using a camera mounted on a drone, the drone will be automatically driven and filmed based on the filming plan (filming sequence, movement and execution guidance). Of course, operators can also remotely control the drone, adjust conditions, and film.

[0019] Furthermore, based on the already created 3D construction data 20 (3D model data obtained from construction drawings, or BIM (Building Information Modeling) 3D data currently in use) for construction, reference images to be referenced during shooting are created and stored in the reference image data memory 122 within the shooting, display, and notification management means 120. In creating reference images, the 3D image of the object to be photographed and preserved is moved on the computer's display screen, and an appropriate image is selected from images viewed from various sizes (corresponding to the distance between the object and the camera at the time of shooting), angles, or directions. There may be more than one image per object. Simultaneously, conditions such as distance, angle, or direction are stored in the shooting condition correction support means 123 as shooting conditions, associated with the reference image, and provided as correction support such as display, notification, or automatic adjustment of the current position, movement distance, direction, angle, etc. of the imaging means relative to the object, such as "move 1m to the right," when the reference image is determined. When the reference image is determined, there are positions (distance from the object to be constructed), directions, angles, etc. that are viewing the object to be constructed corresponding to that reference image (corresponding to camera shooting), so it is desirable to calculate these as shooting conditions, including at least the distance between the camera and the reference point, based on a reference point set on the object to be constructed. Furthermore, the conversion from 2D drawings to 3D drawings, and vice versa (like BIM), is now possible using readily available, off-the-shelf software. Furthermore, the reference images may be provided as contour diagrams or contour-enhanced diagrams within the 3D data. As described above, in creating reference images, based on correspondence descriptions such as construction drawings and BIM model data, the conditions such as shooting position, inclination angle, and separation distance are changed in preparation for the shooting process, and corresponding reference images are generated. The most appropriate reference image is then selected and created.

[0020] As described above, after the shooting plan table 121 and the data in the reference image data memory 122 are prepared, the shooting / display / notification management means 120 determines the shooting time based on the shooting plan table 121 using the shooting time determination means 124A. It is also possible to include a time related to the shooting date, such as one hour prior to the shooting date, in the determination. When it is determined that it is time to take a photograph, the reference image display means 125 displays a reference image of the object to be photographed on the display within the photographing means 150, or on the display surface of the linked display / notification means 190. Therefore, when the camera 151 of the photographing means 150 captures an image of the object, both the reference image and the image of the object are displayed on the display surface. To achieve this, the system provides captured images of the object either directly from the camera 151 or via the temporary image memory 152 that temporarily stores the captured images, and reference image data provided via the reference image display means 125. A reference image from memory 122 is provided to the image synthesis means 160, where the two images are synthesized to display identically, and then displayed on the display / notification means 190. Furthermore, the so-called image synthesis technique used to simultaneously display both the captured image of the object and the reference image is a well-established technique described in numerous publications and can therefore be utilized. Furthermore, it is desirable that the shooting conditions are displayed in conjunction with the reference image by the shooting condition correction support means 123. In addition, the shooting condition correction support means 123 can also guide the user by providing alignment conditions (e.g., 1m to the side, 10 degrees upward, 30 degrees to the right) by comparing the captured image of the object with the reference image, and it is also possible to perform automatic position and direction alignment using artificial intelligence. Alternatively, from a different perspective, the reference image creation means 140 can return the image of the object taken by the shooting means 150 and request the presentation of a reference image that matches the image of the object taken by the shooting means 150. Furthermore, it is desirable that the display and notification means 190 not only has the function of displaying and notifying, but also has various operation execution functions such as selection, input, and movement, as is currently done.

[0021] The above points will be further explained in the case of a camera held by the worker. A more detailed explanation would be provided if the shooting method 150 is the camera held by the worker as described in 1) above. The operator is notified based on the judgment made during the shooting process by the shooting judgment means 124A. Upon notification, the worker recognizes the execution of the shooting plan via the shooting device 150 or the associated display / notification device 190, and recognizes that a reference image of the object to be photographed is displayed or can be displayed on the display within the shooting device 150 or on the display surface of the linked display / notification device 190. In other words, without a reference image, there is a risk of taking a photograph of the wrong object or one that deviates from the specifications, such as being oriented incorrectly. However, with a reference image, the operator can recognize the object by comparing it to the actual object and the reference image. Therefore, by pointing the camera 151 of the shooting means 150 at the object and displaying the image of the object taken by the camera 151, the differences between the image of the object and the reference image can be recognized. Differences in size can be intuitively recognized as differences in distance or magnification, and differences in orientation as differences in horizontal and vertical angles. The operator can then easily change the shooting conditions, such as moving the camera 151 or changing the magnification, to minimize these differences and achieve the desired photograph.

[0022] The captured images of the objects are stored in the image data accumulation means 170 in association with reference images. Furthermore, the performance table creation means 180 creates a performance table based on the captured images of the objects.

[0023] The captured images of the objects are provided to the construction completion rate determination means 200, where the similarity and correlation with the associated reference image are calculated. Once the construction completion rate is determined, it is used for construction management and can also be fed back into the schedule 10 and the 3D construction data 20. Furthermore, the performance table creation means 180 can conveniently incorporate the construction completion rate into the performance table.

[0024] Figure 2 shows one embodiment of the operation flow of the construction image capture system according to the present invention. Furthermore, the BIM model data shown in Figure 2, along with the schedule and construction drawings, is an example of a simple completed building drawing; naturally, the drawings will differ for each stage of the process. 2-1: Based on the construction drawings or BIM model data and the schedule, create a shooting plan and reference images. 2-2: A determination is made at the current time or a related time (e.g., 1 hour ago). If the result is YES, the camera proceeds; if NO, the determination continues. 2-3: In the shooting process with YES, it is determined whether the captured image of the object displayed on the screen approximates or matches the reference image. If NO is selected within the desired range, movement operations are performed in a direction that matches conditions such as distance, magnification, orientation, and angle, and it is determined again whether they match. If it is determined that they match, the image is captured and the process proceeds to the next step. 2-4-1: The captured image of the object is stored in the image data storage means 170 in association with the reference image. 2-4-2: Simultaneously, the captured images of the object are incorporated into the performance image list by the performance table creation means 180. Furthermore, preferably, 2-4-3: In the construction completion rate determination means 200, the degree of agreement and correlation between the photographed image of the target object and the reference image is calculated, and the construction completion rate is determined. Also, preferably, 2-4-4: This will be reflected in construction drawings, BIM model data, and project schedules. After 2-4-2 or 2-4-4, 2-5: The process completion determination means 124B in Figure 2 determines whether all scheduled events in the shooting plan have been completed. If the result is NO, the process returns to the shooting time determination in 2-2, and the decision for the next shooting is made. If the result is YES, the execution of the shooting plan is complete and the process is finished. Furthermore, in the case of determining the end of a process, if the determination is made at the time of shooting, the entire process can be determined to be complete if there are no more shooting plans that need to be determined. Therefore, the shooting-time determination means 124A can take over the role of the entire process completion determination means 124B, and thus the entire process completion determination means 124B is not essential.

[0025] Figure 3 shows one embodiment of the shooting schedule for the construction image capture system according to the present invention. The schedule shown in 3-A describes the planned stages of each construction phase. It is desirable to also indicate the time of photography, as in this example. In 3-B, corresponding to the process chart, a shooting plan is shown. In this example, the table lists the shooting schedule (year, month, day, hour, minute, etc.), related process name, shooting conditions, shooting method (camera held by the worker (indicated by patrol), fixed camera at the site, camera mounted on a drone), and the associated reference image number for retrieving reference images. In particular, the shooting conditions and reference image numbers are linked in this table, and when a reference image related to a reference image number is displayed, the shooting conditions can be easily obtained and used for display and notification. Furthermore, as in this table, once the number of the captured image is entered into this table after shooting, it becomes easy to link it with the reference image.

[0026] Figure 4 shows one embodiment of the process of capturing and acquiring an image of an object using the construction image capture system according to the present invention. In this example, the diagram shows the shooting process after all steps have been completed. However, if the shooting is completed after each step, the diagram would show the parts corresponding to each step. In 4-A, the reference image of the object to be photographed is displayed on the display within the shooting means 150, or on the display surface of the linked display / notification means 190, via the reference image display means 125. Upon seeing this, the worker recognizes the actual object being worked on, thinking, "This is it." Next, in 4-B, when the camera 151 of the shooting means 150 is pointed at the object, an image of the object is displayed along with the reference image. In the case of 4-B, the worker notices that the image of the object is larger than the reference image and is being taken from the front. So the worker moves to the side and the display becomes as shown in 4-C. The worker notices that only the size is different and moves away from the object. The image of the object becomes smaller. At an appropriate position, a state where the image of the object and the reference image are almost identical, like in 4-D, can be easily obtained, and the shutter of camera 151 is pressed to complete the shooting. Section 4-E shows the actions taken up to the point of taking the photograph and the image of the subject. The image of the object and the position, orientation, and angle of the camera 151 at the time of shooting are shown, and the differences in shooting conditions and captured images for B, C, and D are shown in correspondence with 4-B, 4-C, and 4-D.

[0027] Figure 5 shows another embodiment of the process of capturing and acquiring an image of an object using the construction image capture system according to the present invention. In 5-A, as described above, the display surface of the shooting means 150 or the display / notification means 190 linked thereto displays both a reference image of the object to be photographed and a photographed image of the object to be photographed. In 5-B, the method does not adhere to this, but instead displays a reference image of the object on a portable display device 500 held by the worker, and displays a captured image of the object on the display surface of the shooting means 150 or a linked display / notification means 190, allowing the worker to compare the two images and change the shooting conditions before taking the picture. In this case, although the shape can be determined, the size of the two images cannot be compared. Therefore, the operating conditions can be defined as taking the image of the object so that it is almost entirely contained within a frame provided on the display surface of the shooting means 150 or the display / notification means 190 linked thereto. Furthermore, when the reference image of the object and the captured image of the object are simultaneously displayed on the display surface of the shooting means 150 or the display / notification means 190 linked thereto, Figure 7-A shows an example of the configuration of the main components when the reference image of the object is displayed on a portable display device 500 held by the worker, and the captured image of the object is displayed on the display surface of the shooting means 150 or the display / notification means 190 linked thereto. Furthermore, if a reference image is available, instead of displaying it on the portable display device 500, it is also possible to print the reference image and shooting conditions on paper and take the picture while referring to this. Reference images have a wide range of applications in assisting photography. In 7-B, as shown in the diagram, only the camera 151 is configured separately from the other components. Figure 7 shows a partial configuration of Figure 1.

[0028] Figure 6 shows another embodiment of the process of capturing and acquiring an image of an object using the construction image capture system according to the present invention. 6-A differs from 5-A in that it uses a drone equipped with a camera 151 or a shooting means 150 having the camera, but is otherwise the same. The image data of the object captured by the camera 151 (and shooting conditions if necessary) is transmitted via communication, and in the case of remote operation as in 6-B, the operator adjusts the drone and / or camera 151 or shooting means 150 to match the reference image and the captured image of the object, which are simultaneously displayed on the display, and takes the picture. Compared to not using a drone, it is expected that the shooting conditions will be expanded, such as the camera position height, and access to the site will be made easier. In particular, in construction, it is possible to take pictures from dangerous positions that are difficult for people to enter, so using a drone has a unique effect when photographing construction objects. [Industrial applicability]

[0029] As described above, in the construction image capture system according to the present invention, shooting is prompted based on a planned shooting schedule, and the camera's display screen simultaneously displays a reference image used for shooting and an image of the object captured by the camera. By comparing the two, the camera's position and angle can be easily adjusted to match, so that an image of the object according to the planned specifications can be obtained, reducing errors and missed shots, making it extremely convenient for industrial use.
