Abstract

The invention discloses a high-resolution object space telecentric system based on machine vision. The system is characterized by sequentially comprising, from the light incident direction, a first positive lens, a second positive lens, a first negative lens, a diaphragm face, a second negative lens, a third positive lens and a fourth positive lens, wherein the lenses and the diaphragm face are coaxial with the center of an object face, and the distance between the vertex of the first positive lens and the object face is the working distance. The object space telecentric system can effectivelysolve the problem of measurement error caused by inaccurate focusing, and has a large depth of field, so that the area to be measured of an anchor clamping piece can be detected in a larger range. The entrance pupil is at infinity, and the design requirements of the telecentric system are met.

Description

technical field [0001] The invention relates to machine vision detection equipment in optical imaging technology, in particular to a high-resolution object space telecentric system based on machine vision. Background technique [0002] With the progress of modern social science and the development of algorithms such as computer technology and image processing, machine vision technology has been rapidly improved and widely used. With the trend of world industry 4.0 and the proposal of the Made in China 2025 plan, the machine vision system will occupy an increasingly important position in my country's manufacturing industry. Among them, the detection of surface defects of product parts is one of the key applications of machine vision systems. [0003] However, in modern industrial production, the detection of surface defects on curved surface parts is one of the key and difficult points. Due to the complex shape of curved surface parts, it is often difficult to obtain surfac...
