A method for detecting the target position of guide rail based on image processing

Abstract

The invention discloses a method for detecting the target position of a guide rail based on image processing. The steps are as follows: First, start from the initial position on the guide rail of the area where the target to be detected will pass, and set a characteristic circle mark every distance L, and at the same time mark the corresponding numbers in the characteristic circle in order. When the target to be detected starts to move, The image at the guide rail where the target is located is acquired by the image acquisition system and transmitted to the host computer; the host computer analyzes and processes the acquired image, including image enhancement, edge detection and image segmentation operations, and then performs circle detection, feature extraction and Number recognition, finally, the position and movement distance of the target to be measured on the guide rail are determined by the coordinates of the center of the circle marked in the image and the specific number obtained by recognition. The method of the invention is simple to operate, requires less hardware resources, and has high detection accuracy of the target position.

Description

technical field [0001] The invention belongs to the technical field of long-distance non-contact measurement, in particular to an image processing-based detection method for a guide rail target position. Background technique [0002] Measurement technology plays an important role in various fields in modern society all the time. In today's society, with the development of industry and the advancement of science and technology, the requirements for measurement accuracy, efficiency and automation are getting higher and higher. At the same time, in some special occasions and environments such as high temperature, high speed, and small size, traditional measurement methods have been difficult to meet the requirements. Therefore, it is of great practical significance to explore and study new long-distance non-contact measurement methods. [0003] At present, new non-contact measurement methods mainly include photoelectric measurement technology, acoustic wave measurement techno...
