基于DSP的嵌入式数字摄像夜间能见度测量系统
DSP-based measurement system for night visibility of embedded digital camera
摘要
Abstract
One of the key technologies of digital camera night visibility instrument is to process the light source and bold image acquired by CCD in high-speed and real-time way. A miniature and portable embedded visibility measurement system based on TMS32ODM642 was designed, and used in night visibility measurement of digital camera nighttime visibility instrument. The CCD collects PAL video stream at 25 frames per second, and sends it to DSP, with which the segmentation and positioning of light source and bold image are realized, and the night visibility detection of the digital camera is completed. The comparative experiment results show that the embedded system can implement the night visibility measurement perfectly.关键词
