Description

Technical Field

[0001] The utility model relates to the technical field of hardware precision processing, in particular to a device for detecting the surface roughness of a pan / tilt axis based on a visual system. Background Art

[0002] The gimbal axis is a key component in the gimbal system, and is mainly used to control the rotation and tilt of equipment (such as cameras) in the horizontal and vertical directions. The gimbal axis surface roughness detection equipment based on the vision system mainly relies on 3D vision technology to accurately measure the surface roughness information online. The surface roughness of the gimbal axis is one of the criteria for judging whether the gimbal axis is qualified. This device can quantify the difference between the real surface and its ideal shape by capturing and processing the image data of the gimbal axis surface, thereby evaluating the surface roughness.

[0003] During the operation of the gimbal axis surface roughness detection equipment based on the vision system, a clear image is usually captured by a camera. The camera then converts the captured image into an electrical signal and transmits it to the control device. The control device transmits the collected data to the staff through the signal transmission device. Finally, the staff analyzes the image to determine whether the quality of the gimbal axis meets the standards.

[0004] Although the existing gimbal axis surface roughness detection equipment based on the vision system can collect clear images through the camera during use, since the position of the camera is mostly fixed, there are certain blind spots in shooting. Although it is possible to set up multiple groups of cameras to take pictures of the gimbal axis at the same time, the cost is relatively high. Some gimbal axis surface roughness detection equipment based on the vision system uses a motor to drive the rotating shaft to drive the camera to rotate, and then adjust the shooting position of the camera. This adjustment method has a relatively large adjustment range, which will reduce the clarity of the camera shooting during the adjustment process, thereby affecting the subsequent image analysis effect.
