Monocular 2D Displacement Measurement System Based on STM32F407

In the context of the increasingly progressive industrial development, in order to ensure the safety and efficient of industrial production needs, it is particularly important to carry out automatic two-dimensional displacement monitoring for large structures such as specific devices and pipelines in the industry. In view of the shortcomings of the existing monitoring system, this paper presents a monocular two-dimensional displacement measurement system based on single chip microcomputer, which not only guarantees the accuracy, but also greatly reduces the cost of 2D displacement monitoring. This method first preprocesses the image. To get the edge information, the circle detection method based on Hough transform will be used to obtain the pixel coordinate information of the target circle, and the world coordinate of the plate target circle center will be solved by using the pixel coordinate relationship between the known reference circle and the target circle. In order to verify the effectiveness of the system in the corresponding application scenarios, a test platform is build to test the system. The results show that the measurement error can be controlled within 1 mm.
