Abstract

The invention discloses a target detection method and device, aims to ensure credibility of a detected target and further improve accuracy of target detection, and belongs to the technical field of sensors. The target detection method comprises the following steps of when a first target and a second target are the same target, obtaining a fusion confidence degree according to a first confidence degree and a second confidence degree; wherein the first confidence coefficient is the credibility degree of the first target in a first image, the second confidence coefficient is the credibility degree of the second target in a second image, the first image is an image from a first camera device, and the second image is a look-around image obtained according to images from a plurality of camera devices; wherein a plurality of camera devices comprise the first camera device; and outputting a target detection result according to the fusion confidence. The method can be used for target detectionand tracking in auxiliary driving and automatic driving.

Description

technical field [0001] The present application relates to automobile intelligent assisted driving technology, and in particular to a target detection method and device. Background technique [0002] With the development of society, smart cars are gradually entering people's daily life. Sensors play a very important role in assisted driving and automatic driving of smart cars. Various sensors installed on the car, such as millimeter-wave radar, lidar, camera, ultrasonic radar, etc., sense the surrounding environment at any time during the driving process of the car, collect data, identify and track moving objects, and static Recognition of scenes such as lane lines and signs, and combined with navigator and map data for path planning. Sensors can detect possible dangers in advance and help drivers in time and even take necessary avoidance measures autonomously, effectively increasing the safety and comfort of car driving. [0003] In the related technology, multiple camera...
