Abstract

In order to realize real-time depth detection of structured light system

simplify framework of structured light system and reduce cost

design structured light depth detection system based on field programmable gate array（FPGA）.Structured light image processing algorithm is modified adapt to hardware

use pipe-lining technology of hardware system and parallel computing techniques

improve processing performance of system

propose ping-pang cache structure.Box filtering and parallel pixel processing computation increase processing speed

and ensure the real-time performance of algorithm.Experiment shows that this system can realize depth detection function and processing speed is far superior to software processing

which meets the real-time requirements.
