Abstract

Embodiments of the present application provide an image-based position detection method, device, device, and storage medium. Images captured at the same time by multiple shooting devices erected in different orientations are obtained, wherein the time of the multiple shooting devices Synchronization; detecting the two-dimensional position of the target object in each image; based on the two-dimensional position of the target object in each image, and the internal parameters and external parameters of the plurality of shooting devices, determining the target object in the Three-dimensional position in real space. The embodiment of the present application implements a multi-camera-based three-dimensional positioning solution, which improves the reliability and accuracy of object positioning.

Description

technical field [0001] The embodiments of the present application relate to the technical field of artificial intelligence, and in particular to an image-based position detection method, device, device, and storage medium. Background technique [0002] With the advancement of social intelligence, unmanned supermarkets have attracted widespread attention as a new retail method. At present, the relevant technologies of unmanned supermarkets are not very mature, especially how to judge the customer's location through multiple cameras and keep track of the location is a difficult point. [0003] At present, the image-based positioning method is mainly based on the pictures taken by a single camera. The two-dimensional position of the target object is detected in the image through the pre-trained detection model, and the position of the object is positioned according to the two-dimensional position. However, when the target object is occluded, or the two-dimensional position det...
