Method for identifying cone-shaped mark in miniature traffic environment

Abstract

Embodiments according to the invention provide a method for identifying a cone-shaped mark in a miniature traffic environment. The method includes the following steps of: establishing a ground coordinate system with a miniature smart car as an original point, performing analysis processing on acquired image signals so as to identify the cone-shaped mark, namely, performing scanning pixel-by-pixel to identify red pixels in an image, and marking adjacent red pixels to form red regions in the image; seeking minimum rectangles capable of enclosing the red regions to form red rectangular blocks, numbering the red rectangular blocks and recording coordinates of upper left corner points and upper right corner points of the red rectangular blocks; and performing cone-shaped mark matching on numbered paired red rectangular blocks to identify the cone-shaped mark, thus completing the identification of the cone-shaped mark. The method in the invention can accurately identify the cone-shaped mark in the sophisticated miniature traffic environment, especially in a situation of interference caused by multiple red blocks, thereby, providing accurate road information to the miniature smart car for performing a corresponding driving behavior according to an arrangement position of the cone-shaped mark.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, integrates visual image processing and intelligent transportation, and provides a method for recognizing cones in a miniature traffic environment. Background technique [0002] With the development of the economy and the improvement of people's living standards, traffic activities have become an important part of people's lives. However, due to the rapid growth of automobiles and the relative shortage of roads, traffic problems have become the bottleneck of economic development. Intelligent Transportation System (ITS) was born in the late 1960s. A smart car is a comprehensive system that integrates environmental perception, planning and decision-making, and multi-level assisted driving. The intelligent vehicle driving system intensively uses technologies such as computers, sensors, information fusion, communication, artificial intelligence and automatic control, and is a typical high-t...
