摘要

提出了基于FPGA的车辆避碰系统(VCAS)中Sobel算法的横向车辆边缘检测技术。一般来说，索贝尔算子是一种图像边缘检测器，通过编程实现，并在微处理器上实现。为了简化VCAS复杂的结构，减少主处理器的计算负担，采用FPGA代替程序实现Sobel算法。最后给出了采集到的车辆图像的处理结果，以说明该技术的性能。

FPGA based Sobel algorithm as vehicle edge detector in VCAS

The technology of detecting the edge of lateral vehicle by Sobel algorithm based on FPGA in vehicle collision avoidance system (VCAS) is proposed in this paper. In general, Sobel operator is an image edge detector, which is realized by programming and implemented on the microprocessor. To simplify the complex structure of the VCAS and decrease the computation burden of main processor, FPGA is introduced to realize the Sobel algorithm instead of the program. Processed results of acquired vehicle images are presented to illustrate the performance capabilities of this technology.
