Embodiment Construction

[0043] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0044] 1. Application background

[0045] This paper divides the road and lane detection tasks into several functional modules, and lists several possible methods for the improvement of each module. First, we show how the system breaks down, including enumerating the building blocks and the connections between them in a generic system.

[0046] By reviewing the existing lane and road detection literature, we can find that most of the systems recommended in the literature use the main functional modules, although these modules are implemented in different systems. Based on the commonality among the algorithms, we selected a general system for road and lane inspection, and its functional decomposition is shown in the figure below. The...

Abstract

A general road and lane detection system and method, comprising the following steps: S300 removes interference and image artifacts from input images, and removes irrelevant image parts to obtain related images; S302 extracts lane edge features from the related images or road edge features; S304 fits the path expression model according to the lane edge features or road edge features; S306 tracks the path expression model to integrate time series consistency or position consistency; S308 corresponds the path expression model to the global coordinate system . Through the above-mentioned module design, the present invention can achieve the preprocessing of the image input by the camera, select the relevant image of interest, combine the input information of the lidar to perform lane detection or road detection, and then perform model fitting to estimate the road path. The integration module improves the correct rate of route estimation, and finally, through the coordinate system corresponding module, the real-time correspondence between the image and the global coordinate system improves the correct rate of route estimation, which solves the problem that the function of the existing road estimation model is not perfect.

Description

technical field [0001] The invention relates to the technical field of road perception, in particular to a general road and lane detection system and method. Background technique [0002] Reviewing the existing lane and road detection literature, we can find that most of the systems recommended in the literature use the main functional modules, although these modules are implemented under different architectures. Based on the commonality among the algorithms, we selected a general system for road and lane inspection, and its functional decomposition is shown in the figure below. The system proposed in this paper is general, as no system in the literature contains all the modules shown in the figure. However, almost any algorithm we encountered can be built into a subsystem of this system. Contents of the invention [0003] For this reason, it is necessary to provide a general system for road and lane inspection compatible with most methods, so as to solve the problem tha...
