Abstract

The invention discloses a device and a method for detecting a moving target by using a multi-view camera, and the device comprises four cameras which are respectively a central camera C0, cameras C1-C3, and a control system. The existence of the target is detected through the cameras C1-C3. After a target is detected, a pulse is output to a camera C0, and the C0 is used for imaging the target. Thecamera carries out imaging through a spherical coordinate system, space information is mapped to the spherical coordinate system, and an equation of a tangent plane penetrating through one point on aplane is calculated. Then forming a conical projection from the target object to the small eye in a space spherical coordinate system, and then calculating to obtain an elliptical projection area S to obtain a target elliptical imaging result. According to the invention, the detection difficulty and complexity are reduced.

Description

technical field [0001] The invention relates to a method for detecting a moving target by using a multi-eye camera, and belongs to the cross technical fields of bionics, target detection, video image processing and the like. Background technique [0002] In recent years, moving object detection, as the basis of moving object recognition and tracking, is a hot research issue in the field of computer vision, and has been widely used in video surveillance, robotics, augmented reality and other scenarios, and the research on detection methods based on bionics has Great theoretical significance and application value. [0003] With the continuous development and progress of our country in terms of economy and technology, the detection of targets in videos or images has become an important part of the research in the fields of artificial intelligence and computer vision. For example, in the unmanned driving scene, the bionic compound eye detection system was developed by referring...
