AI Technical Summary

Technical Problem

Existing target following methods for mobile following devices have poor flexibility and require special markers to be placed on the target to determine its position information.

Method used

By performing target detection and feature matching on the acquired target image, a target detection box for following the target is obtained. The navigation data is then updated in conjunction with the coordinate information of the following device to control the movement of the device and avoid dependence on special markers.

Benefits of technology

This enables the tracking device to flexibly follow any target, improving the accuracy and flexibility of tracking and avoiding dependence on special markers.

Abstract

The application relates to a target following method and device, a movable following device and a storage medium. The method is used for the movable following device and comprises the following steps: performing target detection processing and feature matching processing on an acquired target image to obtain a target detection frame corresponding to a following target; obtaining second coordinates of the following target according to the target detection frame and first coordinates corresponding to the following device; updating historical navigation data of the following device according to the second coordinates to obtain target navigation data, and controlling the following device to move based on the target navigation data. The method can improve the flexibility of target following.
