Embodiment Construction
[0028] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings; it should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.
[0029] like figure 2 As shown, the present invention provides a servo-following machine vision device including a vision system, a servo drive system and a host computer task control system. The vision system consists of a lens, a camera, an image processing board and software, etc. It is composed of a reducer, a servo motor, a rotary encoder and a servo controller. The task control system of the upper computer receives and processes the information of the vision system and the servo drive system and instructs the servo drive system to drive the lens of the vision system to rotate accordingly. The vision system is a binocular vision system that rotates independently ...

The invention discloses a servo-actuated machine vision apparatus and a dynamic tracking range finding method. The servo-actuated machine vision apparatus includes a vision system, a servo driving and control system and a host computer task control system, wherein the vision system is formed by lenses, a cameras, an image processing board card and software; and the servo driving and control system is formed by a support, a decelerator, a servo motor, a rotary encoder and a servo controller. The dynamic tracking range finding method is characterized by rotating two cameras which are away from each other by certain distance through servo driving so as to enable the target to approach the optical axis of each camera; measuring the included angle between the optical axis and the baseline through the rotary encoder; and then obtaining the target distance and position through simple geometrical operation, and improving the measuring accuracy through zooming of the lens. The dynamic tracking range finding method can achieve the aim of quick tracking and high accuracy range finding without a complicated characteristic point coupling process. The camera lens of the servo-actuated machine vision apparatus can perform optical focusing randomly to amplify and clarify the target image, and can improve the tracking and range finding accuracy.
Description
technical field [0001] The invention belongs to the field of machine vision, and in particular relates to a servo-following machine vision device and a dynamic tracking ranging method for industrial production. Background technique [0002] Commonly used ranging methods include ultrasonic ranging, laser ranging, infrared ranging, optical ranging, etc., which are mainly used in military, industrial surveying, building construction and other fields. At present, the commonly used visual measurement technologies mainly include the following three methods: binocular stereo vision method, structured light method, and geometric optics method. Most ranging and positioning systems use binocular vision, which is based on the theory of binocular stereo vision. Based on the research on the human visual system, scene information is obtained through binocular disparity. [0003] Binocular stereo vision ranging has the advantages of non-contact, automatic measurement, and harmless to huma...
