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

The invention relates to a universal road and lane detection system and method. The method comprises: S300, interference elimination and image artifact and irrelevant image part removing are carried out on an input image to obtain a relevant image; S302, lane edge feature or road edge feature is extracted from the relevant image; S304, according to the lane edge feature or road edge feature, fitting is carried out to obtain a synthesized path expression model; S306, the path expression model is tracked to carry out time sequence consistency integration or position consistency integration; and S308, the path expression model corresponds to a global coordinate system. On the basis of the module design, pretreatment is carried out on the image inputted by the camera, the interested relevant image is selected; lane detection or road detection is carried out by combining input information of the laser radar; model fitting is carried out to estimate a road path and the accuracy of path estimation is improved by using the time sequence integration module; and then the image corresponds to the global coordinate system in real time by using a coordinate system correspondence module to improving path estimation accuracy. Therefore, a problem that the existing road estimation model has imperfect functions can be solved.

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...
