Embodiment

[0036] This embodiment adopts intelligent vehicle environment perception technology and uses dual cameras to detect road traffic information. The specific process is as follows:

[0037] (1) Determine that the installation height of the two cameras is 1.05m, and install the two cameras with a viewing angle range of 30° at 1 / 3 and 2 / 3 of the lateral distance of the self-designed front bracket of the electric vehicle, as shown in figure 1As shown, the vertical and horizontal installation positions and angles of the two cameras are determined according to the positions of lane lines, zebra crossings, traffic lights and vehicles in front, and the first camera 1 installed at 1 / 3 of the lateral distance of the front bracket of the electric vehicle detects lane lines and zebra crossings, Its optical axis is below the horizontal line, and the angle with the horizontal line is 10°; the second camera 2 installed at 2 / 3 of the lateral distance of the front bracket of the electric vehicle ...

Abstract

The invention belongs to the technical field of road traffic information detection, and relates to a fusion method for detecting road traffic information based on double cameras. Key road traffic information such as lane lines, zebra crossings, vehicles, traffic lights and the like in front of an intelligent vehicle are acquired via double cameras, the lane lines and the zebra crossings are detected by adopting an improved detection algorithm, and the functions of single cameras are promoted by adopting five-frame cyclic detection; features which need to be acquired by the system in different states are determined according to the set logic rule, and the corresponding features are recognized by logic detection, so that the response speed of the system is improved, key information is provided for transverse and longitudinal control of the intelligent vehicle, and a foundation is laid for normal running of the intelligent vehicle in urban roads; and more information is acquired for analysis and decision under emergency, so that the defect that the single camera acquires data is overcome.

Description

Technical field: [0001] The invention belongs to the technical field of road traffic information detection, and relates to a fusion method for detecting road traffic information based on dual cameras. The dual cameras are used to detect lane lines and zebra crossings in front of vehicles, and to identify vehicles in front and traffic lights. Background technique: [0002] An intelligent vehicle is a comprehensive system, including environmental perception, planning decision-making, and various auxiliary driving functions. It comprehensively uses technologies such as sensors, communications, artificial intelligence and automatic control, and has become a training ground for modern advanced technologies. With the widespread application of computer vision technology in intelligent vehicles, the vision-based intelligent vehicle surrounding environment perception technology is also developing continuously, and has become a hotspot in intelligent vehicle research. [0003] The su...
