Strip Detected System Design Based on Area Array Image Sensor

To overcome the deficiencies of the existing strip detected technique,a new detection scheme using linear laser mating planar array CMOS image sensor as the location of the strip means of detection is proposed.A high-speed embedded image processing system is designed based on the new characteristics of strip detection.The data quantity is reduced and the frame rate is improved by the sensor hardware windowing technology.The measuring accuracy is improved by using the sub-pixel technology.And the shortcomings of traditional plane array image sensor system such as low frame rate,long lag,and insufficient resolution are overcome.The system can meet the needs of high speed strip detection and control.
