Technical Field

[0002] Machine vision mapping instruments are devices that use computer vision technology for measurement and mapping. They simulate the human visual system and combine image processing and analysis technology to automatically detect and measure parameters such as the size, shape, position, and motion state of objects. Machine vision mapping instruments are widely used in industrial automation, quality inspection, 3D reconstruction, navigation positioning, medical imaging and other fields.

[0003] The machine vision system captures the image of the angle reference through the built-in camera, and uses image processing software to analyze the feature points in the image to calculate the measurement value of the angle reference. By comparing the angle value calculated by the machine vision system with the precise angle reference provided by the calibration auxiliary device, the angle measurement parameters of the machine vision system can be calibrated. If there is a deviation, the parameters of the machine vision system, such as focal length, distortion correction, etc., can be adjusted to improve the measurement accuracy. During the calibration process, all measurement data and calibration results will be recorded for subsequent analysis and quality control. If necessary, the calibration auxiliary device can also provide feedback signals to guide the machine vision system to perform automatic calibration.
