Camera multi-dimensional fine adjustment protection device and adaptive adjustment method

Abstract

The invention relates to a camera multi-dimensional fine adjustment protection device and a self-adaptive adjustment method, and mainly aims to solve the technical problems that camera arrays of inspection vehicles or robots such as tunnels and pipe galleries are difficult to install and adjust, and the manual focusing efficiency of lens focal lengths is low. According to the technical scheme, the device is composed of a three-dimensional fine adjustment mechanism, a camera parameter automatic adjustment system and a camera protection cylinder. The three-dimensional fine adjustment mechanism is composed of a connecting rod, a lower support, an upper support and a camera connecting block. The camera protection barrel is composed of a front cover, a front lens barrel, a main lens barrel and a rear cover. The three-dimensional fine adjustment mechanism is connected with the camera main lens barrel through a bolt; the camera can realize three-axis winding fine adjustment around the X axis, the Y axis and the Z axis through the fine adjustment mechanism, and mutual interference is avoided; the camera parameter automatic adjusting system is composed of an annular ultrasonic motor and an image quality evaluation system, and through traversal of the annular ultrasonic motor and combination of the image quality evaluation system, rapid and automatic adjustment of camera focal length and aperture parameters is achieved.

Description

technical field [0001] The invention relates to a camera adjustment protection device, in particular discloses a camera multi-dimensional micro-adjustment protection device and an adaptive adjustment method, belonging to the technical field of machine vision. Background technique [0002] With the rapid development of machine vision technology, more and more non-destructive and rapid detection fields of municipal, water conservancy, transportation and other infrastructures have been applied. The main equipment based on machine vision detection is the camera, most of which are industrial cameras. For different detection targets, the number of cameras required is also different, ranging from one to dozens. The accuracy of the installation position of the camera and the setting of parameters have a direct impact on the image quality, and will further affect the effect of machine vision recognition. Due to the existence of mechanical processing errors, the installation position...
