Problems solved by technology

Although these vulnerable road users often appear in the driving environment at the same time, traditional object detection methods detect these objects separately, which not only results in multiple scans of the input image, but also results in confusing detection results that cannot be distinguished Pedestrians, cyclists or motorcyclists

Abstract

The invention discloses a vulnerable road user joint detection method, and the method comprises an offline training stage and an online target detection stage. The offline training stage comprises the steps: 1), building a vulnerable road user database which comprises a training sample set and a test sample set; 2), constructing a VRU detector, which can recognize a vulnerable road user target from the background, according to the training sample set. The online target detection stage comprises the step: 3), carrying out the classification and positioning of targets in the test sample set through employing the VRU detector, and outputting a detection result. The method can be used for the protection of vulnerable road users in an advanced driving auxiliary system, and also can provide help for the decision of an unmanned vehicle.

Description

technical field [0001] The invention relates to the field of computer vision technology and smart cars, in particular to a joint detection method for vulnerable road users in a vehicle driving environment. Background technique [0002] In the last ten or twenty years, the rapid development of advanced driver assistance systems (such as adaptive cruise system, forward collision warning system, etc.) has improved road traffic safety. However, those vulnerable road users (English full name is "VulnerableRoadUsers", referred to as "VRU"), such as pedestrians, cyclists (hereinafter referred to as "cyclists"), people riding electric vehicles (hereinafter referred to as "Electric vehicle riders") and other small two-wheeled vehicle occupants receive limited protection. According to the 2013 WHO road safety report, nearly half of the world's traffic accident deaths are vulnerable road users, and in some low- and middle-income countries, the proportion of the most vulnerable pedestr...
