Embodiment Construction

[0065] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0066] A traffic police detection method based on clothing features and attitude detection, including the following steps:

[0067] S1: The vehicle-mounted visual sensor collects the original image in real time, and executes step S2;

[0068] S2: Use the improved pedestrian hog feature extraction algorithm to obtain the feature image from the original image XR , using the pedestrian classifier to judge the feature image XR Whether there are pedestrians in , if there are pedestrians in the feature image XR Mark the pedestrian in the middle, and execute steps S3, S4, S7 at the same time, if not, proceed to the next frame detection;

[0069] S3: For feature images XR Using the method of normalized template matching in the pedestrian area, first normalize the hog feature map of the pedestrian area to a fixed size, and then perform template mat...

Abstract

The invention relates to a coat and cap characteristics and attitude detection-based traffic police detection method and system. The system comprises an offline training construct classifier, an online real-time detection traffic police and an attitude thereof, wherein an offline part extracts a pedestrian hog characteristic, a cap hog characteristic, a fluorescent clothes hog characteristic, a construct pedestrian classifier, a cap classifier and a fluorescent clothes classifier through a lot of collected sample images respectively; and an online part collects an original image in real time and judges whether a pedestrian, namely the traffic police who wears the cap and fluorescent clothes at the same exists in the original image or not by the pedestrian classifier, the cap classifier, the fluorescent clothes classifier and various combinations, then judges the attitude of the traffic police, and prompts a driver to help the driver correctly understand the attitude of the traffic police. The detection method is broadly divided into two processes of accurate matching and fuzzy matching; the two processes can be corroborated by each other; the traffic police and the attitude thereof can be accurately and quickly detected; and the coat and cap characteristics and attitude detection-based traffic police detection method and system have important guiding significance in active driving.

Description

technical field [0001] The invention belongs to the field of active driving, in particular to a traffic police detection method and system based on clothing features and posture detection. Background technique [0002] In recent years, the development of autonomous driving technology in automobiles has been in full swing, and various automakers and technology companies have launched their own autonomous driving test concept cars. These experimental concept cars use pedestrian detection, vehicle detection, traffic signal detection, GPS positioning and map search, path planning and other technologies to guide them to drive autonomously, or even unmanned. These experimental cars can control and drive the car almost completely without human operation under some relatively common road conditions. But in some special traffic scenarios, it is the traffic police who direct the behavior of vehicles. However, the current self-driving vehicles have not actively responded to the traff...
