High accuracy vision detection system

Abstract

The high precision vision detection system includes the digital staff guage system, the illuminating system with adaptive adjusting optical intensity, the auto focus system, the optical image system, the vision detection software, the foundation, the computer or microprocessor system. The digital staff guage system is used to provide the high precision length detection base in large scale; the illuminating system is used to adjust the optical intensity according to the different of the detection distance, detection angle and the surface reflectivity of detected workpiece to provide the uniform and stable illuminating intensity to pledge the image quality and the detection precision; the auto focus system is used to adjust the working distance of the detection system to pledge the image has the good quality and constant amplification ratio and pledge the repeatability and detection precision of the detection system; the optical image system is the main part of the detection system, which is used to transform the geometry outlook of detected workpiece to the computer or processor through the optical lens image, the vidicon photoelectricity switch and collecting control circuit; the vision detection software is used to process the image and get the detection result; the foundation is the supporting frame of vision detection system, which is used to fix, support and move every part of system; the computer or microprocessor system is the core part of the whole vision detection system, which is used to coordinate and control every system.

Description

technical field [0001] The invention relates to a high-precision non-contact testing device used in the fields of machinery manufacturing, aerospace, home appliance, automobile and other production and measurement testing. Background technique [0002] With the development of modern science and technology, machinery and equipment in the fields of machinery manufacturing, aerospace, home appliances, and automobiles are all developing in the direction of miniaturization and high integration, and the demand for high-precision key components is also increasing. Technology also puts forward higher requirements. Without measurement, there is no manufacturing. If the detection technology cannot meet the required accuracy requirements, it is impossible to talk about how high the manufacturing accuracy can be obtained by the manufacturing technology, because there is no means to verify the manufacturing accuracy. Whether the required precision has been obtained. With the increasing ...
