Device and method for correcting optical axis deviation of video camera based on binocular stereoscopic vision

Abstract

The invention discloses a device and method for correcting the optical axis deviation of a video camera based on binocular stereoscopic vision. The device includes a base plate and a detection block.One end of the base plate is provided with a bracket, and a binocular image acquisition device is mounted on the bracket. A main mechanism is arranged on the surface of the other end of the base plate. A plurality of mounting holes in an array are arranged on the main mechanism. Bolts pass through the mounting holes connect the main mechanism with the base plate. The length of the main mechanism extending out of the base plate can be adjusted by changing the positions of the mounting holes. The tail of the main mechanism has a tail groove in which the detection block is installed by screws. Through the combination of the device and a CAD three-dimensional model of the device, it is not necessary to know the detailed design parameters of a lens, and the actual coordinate and the ideal coordinate of a few groups of detection corners are obtained through a detection device, so as to effectively and accurately realize the optical axis correction of a binocular stereoscopic vision video camera. The device and the method are easy to operate.

Description

technical field [0001] The invention relates to the field of optical detection, in particular to a camera optical axis offset correction device and method based on binocular stereo vision. Background technique [0002] Binocular vision measurement technology is an important non-contact three-dimensional measurement technology developed on the basis of computer vision. Compared with traditional three-dimensional measurement equipment such as three-dimensional coordinate measuring instrument, laser scanner and laser tracker, binocular vision measurement technology has significant advantages such as fast measurement speed, good real-time performance, and simple structure, and has been widely used in production and life. application. [0003] Because the image acquisition equipment used in the binocular vision system is affected by design errors and machining errors, the lens in the image acquisition equipment of the binocular vision system may have the problem of optical axis ...
