Description

[Technical Field]

[0001] The present invention relates to the related art of non-contact mobile condition inspection, and more particularly to a system and method that enables simulated shooting by a mobile camera. [Background technology]

[0002] The non-contact mobile condition inspection device for underground tunnels uses a camera to photograph the subject at a target speed of 80km / h and inspect the damage condition using the images. However, there is a problem that the quality of the images is not consistent depending on the on-site conditions of each tunnel (lighting, dust, obstacles (tiles, electric wires, etc.)), so optimization or quality analysis standards are required to address this issue.

[0003] For the purpose of analysing the image quality of each tunnel site, a high-speed rotating panel device capable of high-speed indoor shooting is required to compare the images acquired at each tunnel site with images taken in a standard indoor environment (without obstructions).

[0004] The factors that affect tunnel image capture are shutter speed, ISO, fps, lens aperture, and resolution for cameras, and external factors are extremely diverse, including lighting brightness, light reflection, tunnel curvature area, driving speed, dust, and humidity.While various experiments are required to optimize the developed equipment, the reality is that it is difficult to conduct experiments to optimize the equipment at actual tunnel sites. Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has been devised to solve the above-mentioned conventional problems, and aims to provide a system and method that enables image quality experiments using various types of cameras by creating a simulated shooting environment that reflects various site conditions in order to set analysis standards for the image quality of each tunnel site. [Means for solving the problem]

[0006] To achieve the above object, the mobile camera photography simulation system of the present invention includes an image acquisition unit, a panel information input unit, an image acquisition unit information input unit, and an image information calculation unit.

[0008] At this time, the panel can be rotated and moved by a motor.

[0009] The image quality control device may further include an illumination information input unit that receives illuminance information of the illumination that illuminates the panel. With this configuration, the influence of illumination can be more effectively reflected in determining the image quality.

With this configuration, it is possible to provide simulation conditions that take into account the radius of curvature of the tunnel by using the tilt operation of the panel up, down, left, and right.

[0011] The control unit may further include an image acquisition unit control unit that controls the settings of the image acquisition unit, and an illumination control unit that controls the settings of the illumination. With this configuration, images of a wider variety of qualities can be acquired by changing the settings of the camera and illumination.

[0012] The panel may also be provided with a chart for analyzing the width of cracks in the image and a chart for analyzing the clarity of the image, which can be used to analyze motion blur that may occur during high-speed movement, sensitivity to lighting, and the like.

[0013] The device may further include a panel unit including a panel.

[0014] The system may further include a setting information calculation unit that calculates panel operation information and image acquisition unit setting information corresponding to preset image characteristics. This configuration makes it possible to acquire images optimized for on-site conditions and collect images for AI training that reflect future image quality standards.

[0015] Furthermore, an invention in which the system is realized in the form of a method, and a recording medium on which a computer-readable program for executing the method is recorded are also disclosed. [Effects of the Invention]

[0024] Fig. 1 is a schematic block diagram of a mobile camera photography simulation system according to a preferred embodiment of the present invention. In Fig. 1, the mobile camera photography simulation system includes an image acquisition unit 110, a panel information input unit 120, an image acquisition unit information input unit 130, an image information calculation unit 140, a panel unit 150, an illumination information input unit 160, and a control unit 170, and the control unit 170 again includes a panel control unit 172, an image acquisition unit control unit 172, and an illumination control unit 176.

[0025] The image acquisition unit 110 acquires an image of the panel moving in a preset direction and speed. For this purpose, the panel unit 150 includes a panel, which can be rotated by a motor.

[0027] More specifically, the panel unit 150 is equipped with a motor capable of a maximum rotation speed of 100 km / h, and can verify the effectiveness of the rotation speed by measuring the motor's RPM. It also has a 10 km / h speed change function, and can synchronize with the camera's shutter speed and fps and perform optimization analysis.

[0028] In addition, the panel can be tilted up, down, left, and right to analyze image distortion, taking into account the radius of curvature of the tunnel. Sensors that can measure lighting sensitivity in Lux values ​​are installed at each corner and at the top and bottom centers of the panel, making it possible to analyze the effects of lighting. The system is equipped with software that can electronically control rotation speed (motor RPM), speed changes, lighting sensitivity changes, etc., and can be executed simultaneously with camera operation.

[0029] This allows for the creation of simulated rotating panels and indoor environments that reflect various field conditions, enabling image quality experiments using various types of cameras.

[0030] The panel information input unit 120 receives operation information of the panel, the image acquisition unit information input unit 130 receives setting information of the image acquisition unit 110, and the image information calculation unit 140 calculates image characteristic information corresponding to the operation information of the panel and the setting information of the image acquisition unit 110.

[0031] The illumination information input unit 160 receives illuminance information of the illumination that illuminates the panel. With this configuration, the influence of illumination can be more effectively reflected in determining the quality of an image.

[0032] The panel control unit 172 controls the height and tilt of the panel. With this configuration, it is possible to provide simulated conditions that take into account the radius of curvature of the tunnel by using the tilting operation of the panel up, down, left, and right.

With this configuration, it is possible to acquire images of a wider variety of qualities by changing the camera and lighting settings. Figure 7 is a diagram showing the control software configuration of the control unit.

[0034] The panel may also be provided with a chart for analyzing the width of cracks in the image and a chart for analyzing the clarity of the image, which can be used to analyze motion blur that may occur during high-speed movement, sensitivity to lighting, and the like.

[0035] More specifically, by attaching a crack width size chart or ISO standard clarity analysis chart, you can analyze the motion blur of images that may occur during high-speed movement, sensitivity to lighting (linked with the camera shutter speed), etc.

[0036] The setting information calculation unit 180 calculates panel operation information corresponding to preset image characteristics and setting information for the image acquisition unit 110. This configuration makes it possible to acquire images optimized for on-site conditions, and to collect images for AI training that reflect future image quality standards.
