Problems solved by technology

However, most of the current technologies use CCD imaging equipment, and use CCD cameras to realize the function of image acquisition. Because the CCD image acquisition equipment itself has defects such as high cost and large volume, it is common to use CCD cameras to realize two-way vision systems. Problems such as system complexity and low integration level limit the wider application of this technology

Embodiment Construction

[0007] The present invention is further described as follows with reference to the accompanying drawings in conjunction with the embodiments: Compared with the CCD imaging device, the CMOS photoelectric sensor directly generates a current (or voltage) signal after photoelectric conversion, and the signal reading is very simple. Using CMOS technology can simplify the circuit design, shorten the development cycle, and enhance the reliability of the system. The CMOS photoelectric sensor can take out the electrical signal while collecting the optical signal, and can also process the image information of each unit at the same time, which is much faster than the CCD. At the same time, CMOS is small in size and consumes less power, so it has a wider range of applications than traditional CCD imaging equipment. The development of large-scale integrated circuit manufacturing technology also enables the entire image processing part to be integrated on a circuit board as much as possible...

Abstract

The double-channel location processing system based on CMOS camera chip is formed from CMOS camera chip, lens, signal conversion circuit, programmable control circuit, DSP (digital signal processor) processing chip hardwares and correspondent control processing software. It utilizes the double-channel visual information of same target to make simultaneous processing to implement the function of extractnig location information of relative target. According to the requirements said system can be integrated on an integrated circuit board or integrated on a large chip by means of customized (ASIC, special-purpose integrated circuit) chip.

Description

Technical field: [0001] The invention relates to the technical field of information processing, in particular to a method and system for positioning and processing two-way image information. Background technique: [0002] With the advancement of science and technology, pattern recognition technology and computer vision technology have made great progress. The technology of using two-way visual information to locate and measure targets has become relatively mature. Positioning, ranging and other tasks are feasible. There are also mature technologies for system initial calibration and error correction. However, most of the current technologies use CCD imaging equipment, and use CCD cameras to realize the function of image acquisition. Because the CCD image acquisition equipment itself has defects such as high cost and large volume, it is common to use CCD cameras to realize two-way vision systems. However, problems such as system complexity and low integration level limit th...
