Research And Application Of Target Location System Based On Monocular Vision

With the continuous improvement of the degree of science and technology in modern society,computer vision has been widely used in many industries.Computer vision as a new technology,the accuracy of target recognition,the accuracy of target positioning and the complexity of the visual system is the most important of several indicators.Although the target positioning binocular detection scheme is easier to achieve than the monocular scheme,the relative position of the binocular camera may change slightly after each actual operation,and the physical parameters such as the parallelism of the dual camera are needed.The use of monocular program to avoid the relative position calibration problem,because the target positioning system is simple,low cost and has a strong real-time,very suitable for industrial production,the perfect fit of the design requirements of this article.This paper designs a positioning and recognition system for monocular vision.The system consists of the hardware platform and the corresponding motion control and image analysis software.The hardware platform of the system consists of a monocular array camera,a positioning target and a moving device.The main function is to complete the high quality image acquisition of the target recognition and positioning system.In this paper,we use the array camera to complete the image data acquisition.For the distortion of the array camera,this paper uses Zhang calibration method for camera calibration,and has good effect.The system software implements the image processing algorithms such as collecting image data,edge image generation and filtering target contour.And the positioning problem of the image object with the artificial flag positioning target in the case of single camera is studied deeply.The method of locating target objects based on geometric relation is realized by using the known square target size information and calibration map.The final experimental results show that the algorithm used in this paper can not only take into account the high real-time performance.The system can be used for industrial production positioning control links,can improve the degree of industrial production automation and efficiency.
