Abstract

The invention provides a method and device for locating and a target device. The specific implementation mode of the method includes the steps that a relative posture and a relative position between the target device and a reference object disposed on the locating device are determined based on image data; a reference posture of the target device relative to the ground is determined, and the reference posture is obtained based on inertial measurement data of the target device; and according to the reference posture, the relative posture and the relative position, a target posture and coordinates of a target position of the target device in a coordinate system corresponding to the locating device are determined. The implementation mode can effectively reduce the locating error and improve the accuracy of locating.

Description

technical field [0001] The present application relates to the technical field of navigation and positioning, and in particular to a method, device and target device for positioning. Background technique [0002] At present, with the widespread promotion of unmanned equipment (such as unmanned vehicles, unmanned flying equipment, unmanned ships, etc.), navigation and positioning technology has become more and more important. Unmanned driving equipment generally needs to refer to the positioning device with image identification for positioning, so as to perform precise docking / precise delivery. Taking the unmanned equipment with flight function as an example, when performing precise docking / precise delivery, it is usually necessary to collect image data for the positioning device with image identification, and perform positioning based on the image data. However, generally speaking, positioning using the above method will generate a relatively large positioning error. Conte...
