Abstract

Aiming at the increasing demand of space dim and weak target detection camera and meeting the demand of small size and light weight, this paper proposes the design and implementation of a light and small low light level camera based on FPGA. The camera adopts IMX253, a high resolution and high response CMOS image sensor produced by SONY. FPGA is used to receive the data output by the sensor, cached in DDR3, and then transmitted to the data transmission system through TLK2711 interface. This paper introduces the camera system scheme, hardware design and camera driver with FPGA as the control core. Verilog hardware language is used to realize IMX253 timing drive, image acquisition, DDR3 data cache and TLK2711 interface communication. The imaging experiment of the system is carried out. The results show that the camera system runs stably, has high imaging quality and strong detection ability. The camera image resolution is 2048*2048, quantization bit is 12bit, frame rate can reach 20Hz. This system provides effective image data for space weak target detection.
