Embedded vision detecting system

Abstract

The invention relates to an embedded vision detection system, which is provided with a multi-state power control unit, an image acquisition control and preprocessing unit, an image analysis unit and a human-computer interactive unit, wherein the operation of the system starts from the image acquisition control and preprocessing unit which is communicated with the human-computer interactive unit through a control bus and an image transmission bus (DMA mode) and is communicated with the image analysis unit through the control bus and a DSP video interface VIP; simultaneously the image analysis unit and the human-computer interactive unit interact information and are connected with each other through a parallel interface HPI; and the multi-state power control unit supplies mains voltage to the modules. Compared with the prior art, the embedded vision detection system integrates the characteristics of a PC vision system and an intelligent camera, shows both the high performance and the human-computer interactive ability, can simultaneously meet different applications of high real-time object detection, medium real-time object detection, high-resolution object detection, medium-resolution object detection, medium-distance object detection and far-distance object detection in the aspect of input by various video interfaces provided by the system, and can be completely used for high-complexity detection of objects in a high-speed flow line and output of the detection results.

Description

Technical field: [0001] The invention relates to a vision system, more specifically to an embedded vision detection system. Background technique: [0002] In traditional inspection, workers usually inspect the processed objects through tools such as dial indicators, centering gauges, and calipers. With the development of industrialization, traditional inspection technologies have been difficult to adapt to the needs of existing industrialized mass production. Through the image acquisition and analysis of the detection target, the vision system can automatically complete the measurement of the target quickly, accurately and with high repeatability, and is widely used in industrial automation production. At the same time, in many automated production lines, it is necessary to perform high-speed and high-complexity inspection on the workpiece, but the space left for the inspection equipment is often limited, so the size of the inspection system is also required, so a high degre...

Problems solved by technology

It can achieve ideal accuracy and speed, and can realize complex detection functions, but the system size is large, the structure is complex, and the development cycle is long

The other is a smart camera. For different applications, simple programming is performed through a handheld programming device. The system has a light structure, simple operation, and fast development speed, but the application complexity is limited, and it does not provide image output, so it cannot monitor production in real time. process
