Hardware, System on a chip
In this paper, we present a novel System on Chip design for real time lane detection approach on low-quality grayscale images. The proposed method leverages the sequential read out from image sensors to progressively build clusters. The decision to allocate pixels to existing lines (clusters) is made on the fly as pixels flow from the image sensor into the system. We propose a hardware/software partitioning that places low-level computational intensive parts in a pipelined chain in hardware. The pipeline first applies morphological operations on incoming images to enhance their quality. Later canny edge detection followed by Probabilistic Hough Transform is used for accurate line detection. The lines are then filtered and clustered before being fitted into road lanes using weighted least squares method. We prototype our design on a system on FPGA with a precision above 90% and demonstrate a speedup of 2.09x compared to a software only implementation on an embedded processor.
