Problems solved by technology

[0005] In addition, the panoramic vision sensor at this stage has three solutions: multi-camera splicing, catadioptric, and ultra-wide-angle lens splicing. The cost of the multi-camera splicing solution is relatively high, and the catadioptric camera has limited usage scenarios and can only generate cylindrical panoramas. picture

Abstract

The invention discloses a panoramic three-dimensional visual sensor and a using method. The visual sensor at least comprises three wide angle cameras fixed to a set mold, wherein any two cameras are placed on one side of the mold, and the third camera faces the other side of the visual sensor. Images collected by the two adjacent cameras are utilized for carrying out image three-dimensional vision analysis, images collected by all the cameras installed on the visual sensor mold are utilized for achieving image panoramic splicing, then all-directional visual analysis is carried out, and whether one object needing to be concerned exists or not is analyzed. According to the panoramic three-dimensional visual sensor, the characteristic of visual recognition of multi-view vision of a three-dimensional visual sensor and the characteristic of being capable of simultaneously collecting images in multiple directions of a panoramic visual sensor are combined at the same time, so that the panoramic three-dimensional images of the target object and the surroundings are represented.

Description

[0001] technical field [0002] The invention relates to the field of visual sensors, in particular to a panoramic three-dimensional visual sensor and a method for using the same. Background technique [0003] With the development of computer vision and artificial intelligence, the form and function of visual sensors are also rapidly improving. Existing visual sensors are usually divided into two categories, one is focusing on 3D stereo vision, capturing images of real objects through two or more cameras, and obtaining the motion of objects by analyzing the collected images pose and distance from the camera. The other category is the emerging panoramic image acquisition scheme in recent years. By fixing cameras aimed at different directions, images from various angles around the object are collected, and a panoramic image around the object is obtained after calibration and splicing. [0004] However, the stereo vision sensor only focuses on one direction, while the panoram...
