摘要
在基于CMOS数字摄像头实现图像二值化方案中,多数是通过摄像头的并行I/O数据口采集数据,并交由MCU来完成二值化的处理,这种方式占用MCU的时间、且数据量大,不利于传输和处理。文中设计了灵活运用额外的硬件和数字逻辑电路对图像进行二值化和压缩处理,减少了图像在片内的存储空间,缩短了传输和软件处理时间,提高了系统检测的实时性。
The image binarization of CMOS-based digital cameras mostly collects data via the parallel I/O port of a digital camera and refers the binarization process to MCU, which occupies the MCU with enormous data and slows down the transmission and processing. In this article, extra hardware and logic circuit are utilized for image binarization and compression to reduce the occupied internal storage space, shorten the time of transmission and software processing and improve the real-time performance in system detection.
