Abstract

The invention belongs to the technical field of video analysis and particularly relates to a system for accurately positioning a mechanical part by machine vision in an industrially-structured scene. The system comprises a camera arranged rightly above a part holding platform, an LED (light-emitting diode) light source and a computer, wherein the computer is provided with a software processing system; the software processing system comprises a software interface starting module, a camera calibrating and correcting module and a sample training module, and further comprises an image analyzing module and a communication module; when the system works, the image analyzing module is used for accurately and timely detecting and positioning the part and the communication module is used for transmitting a processed result to an executing device; performance differences of different image characteristic extracting methods are integrated by the system to form a set of cascading analysis algorithm; and erroneous detection rate is reduced under a limited calculation resource, so that the accurate identification and positioning of a target object is guaranteed, and the analysis is carried out in real time; and therefore, the actual requirements of industrial production are met.

Description

Technical field

[0001] The invention belongs to the technical field of video analysis, and specifically relates to a positioning detection system for mechanical parts in an industrialized scene based on video. Background technique

[0002] With the advancement of science and technology and the increase of labor costs, the industry's demand for automated and intelligent production tools continues to grow. Repeated and boring parts sorting can be done by machines controlled by intelligent software, which greatly reduces the company's demand for labor. . At the same time, a reasonably designed automated machine can perform repetitive work in a structured scene with high precision and for a long time. Compared with the manpower, it has obvious advantages, guarantees the quality of standardized products, and reduces the loss caused by human error.

[0003] At present, in addition to the manual sorting of parts, some rely on the special structure of the assembly line to arrange the part...
