基于USB2.0的CMOS图像采集系统的实现

Realization of CMOS Image Accessing System Based on USB2.0

采用OmniVision的OV7620 CMOS图像传感器作为光电成像器件,通过USB2.0控制器CY7C68013A芯片以通用可编程接口GPIFFLOWSTATES流模式实现与传感器的无胶连接,设计了结构简单,使用方便,成本低廉的适用于高速图像采集的硬件系统,并编写了基于多线程技术的软件系统。实现基于CMOS图像传感器的图像数据的采集传输和显示。

Using the OmniVision OV7620 CMOS image sensor as photoelectric imaging device, glueless connecting was achieved between the USB2.0 controller CYTC68013A and the sensor by general programmable interface （GPIF）. The simple high efficiency and low-cost hardware which be apt for high speed image collecting was designed and the software system was also compiled based on the multi-thread technology. The image processing system with acquisition, transmission and display was realized based on the CMOS image sensor.
