Abstract

The invention discloses a vehicle environment sensing method based on an FPGA field programmable gate array. The multi-sensor fused array camera system is installed around a vehicle through omnibearing image collection of the vehicle environment and high-speed transmission and storage of image data, image collection is completed from different angles, intelligent algorithm processing is carried out on images, and a processing result is returned to the central control system. W; wherein image collection mainly aims at a yellow lane line extraction algorithm, and the algorithm can realize detection and perception of vehicle environments under different conditions. Implementation of the algorithm is mainly achieved through an FPGA, and the calculation process and the implementation mode are optimized. Therefore, the intelligent vehicle driving system which is high in speed requirement and small in installation space can be processed.

Description

technical field [0001] The invention relates to a vehicle detection method, in particular to an FPGA-based vehicle environment perception method. Background technique [0002] With the development of computer electronic technology and automatic control technology, intelligent mobile platforms are more and more widely used in military and scientific research fields. Autonomous vehicles are the development direction of the contemporary automobile industry. Although many researchers have invested in research, they still have not really entered the lives of ordinary people. The reason is that the current environmental perception methods are difficult to achieve effective and accurate environmental data acquisition. . Most research methods mainly utilize the vision system, while relatively few studies employ multi-sensors. The use of a single sensor has the following disadvantages: the measurement dimension and confidence of the system are low, the system reliability is poor, t...
