Description

An industrial camera mounting bracket

technical field

The utility model relates to the technical field of detection object surface displacement and strain experiments.

Background technique

Nowadays, many engineering projects need to detect the deformation and displacement of the surface of the object to monitor the state of the object in real time and prevent accidents. Such as dam crack detection, dam deformation detection, bridge deformation detection. When contact with the inspection object is not allowed, we usually use industrial cameras for visual inspection, which requires us to calibrate the camera when installing the inspection platform, and also have higher requirements for the camera mounting bracket.

According to the search, there are currently existing camera mounts suitable for visual inspection devices, such as the Chinese utility model patent with the patent number of 201521122360.5 titled "a camera mount suitable for visual inspection devices", which includes a gantry frame and a For setting the beam of the camera, the beam is slidably arranged on the gantry frame in the vertical direction, and the gantry frame is slidably arranged on the base in the horizontal direction. In this patent, the gantry frame is slid relative to the base in the horizontal direction to adjust the position of the camera in the horizontal direction, and the beam is slid along the gantry piece in the vertical direction to adjust the height of the camera. The use of power devices such as motors increases the design cost, and can only realize the movement of the camera in two degrees of freedom in the vertical and horizontal directions. When the surface of the detection object is a cylindrical surface, there is a large angle between the optical axis of the camera and the surface of the sampling area, and the sampled image will be greatly distorted, increasing the deformation detection error.

Another example is the Chinese utility model patent with the patent number of 201710290666.9 titled "A Vision Correction System for a Camera Mounting Frame Based on a Transmission Platform". This patent includes a material conveying platform, and a bracket is arranged on the upper part of the material conveying platform. The camera of the material conveying platform, the camera is erected on the bracket by the movable part, and the movable part can move freely on the bracket, so as to change the position of the camera on the bracket. The device cannot freely adjust the installation angle between the three cameras, and the camera field of view cannot be adjusted according to the sampling area. The position of the camera cannot be precisely fine-tuned in the direction of the camera's optical axis.

The above two patents have defects in visual detection of displacement and strain. In view of the above situation, it is necessary to develop a more precise and higher degree of freedom camera mount suitable for visual inspection.

After placing the object to be detected on the support, first shake the rotary handwheel of the linear slide module to control the vertical movement, and roughly adjust the position of the camera in the vertical direction, so that the optical axis of the camera and the detection area are in line with each other. The center is in the same horizontal position, and then shake the rotating handwheel of the bottom slewing support mechanism to make the side of the arc-shaped support perpendicular to the detection surface. Then, shake the linear slide module to control the rotating handwheel moving in the horizontal direction, so that the camera is close to or away from the detection area, and global measurement and local measurement are realized.

After controlling the linear slide module to make the camera move to the approximate position, manually adjust the micrometer knob on the XR-axis precision stage located in the middle position that controls the movement of the X-axis direction, and adjust the position of the camera precisely to match the focal length of the camera. Adjust to achieve the best imaging effect.

If the detection area is within the field of view of a single camera, the other two industrial cameras may not be used. If the detection area exceeds the field of view of a single camera, multiple cameras are required to detect the detection area. Manually adjust the micrometer knob on the XR-axis precision stage located in the middle position that controls the movement of the R-axis direction to precisely adjust the tilt of the camera lens. Angle, so that the three cameras work together to complete the sampling of the detection area.
