In the process of installation and debugging in the industrial field, it is worth exploring whether the micrometer can be used to replace the high-precision sensors and supporting equipment to measure the amount of jitter of the motion plane. By splitting the micrometer, measuring, simplifying, building a simulation in ADAMS, designing a test scheme according to the scene of LCD panel inspection, and carrying out experimental research and data analysis and processing at different speeds, the results show that the micrometer is capable of measuring the plane jitter of LCD panel production equipment within a certain moving speed. This study provides a feasible basis for the use of micrometers for measurements under mobile conditions, which can significantly reduce the cost of enterprises.
This paper presents an improved stereo vision measurement system with enhanced binocular rectification. Traditional binocular vision algorithms do not constrain the two cameras to be perpendicular to the measurement baseline during the rectification phase, leading to inaccurate vertical distance measurements between two points. To address this issue, a binocular rectification method based on plane normal constraints is proposed. Initially, the camera calibration yields the initial correction transformation matrix. The matrix is then refined by adjusting the correction transformation matrices of both cameras based on the normal of the reference plane. Subsequently, the rectified images are obtained using the refined projection matrices, and the spatial coordinates of the measured points are computed through stereo matching algorithms. Experimental results demonstrate that the improved method enhances measurement accuracy significantly.
