Abstract

As mechanical parking equipment are developing to be complicated, intelligent and familial oriented. The real-time image acquisition and preprocessing of mechanical parking equipment based on CMOS camera and FPGA were proposed to improve the intelligent level and decrease the number of service personnel. The system is constituted by five parts ,i.e., SCCB bus control module, image capture module, image storage module, image preprocessing module and VGA display control module. Using FPGA Cyclone II family chips as the core controller, The CMOS OV7670 image sensor initialization module, image acquisition and storage module, VGA interface protocols, VGA horizontal synchronization and field sync signal were designed using Verilog HDL. The grayscale processing and the fast median filtering algorithm were adopted to preprocess mechanical parking equipment image in FPGA. The experiment results shows that the image after preprocessing can real-time displayed by VGA, and also the system based on FPGA can design flexibility, portability strong, and it can achieve high-speed acquisition and high compatibility.
