AI Technical Summary

Technical Problem

In augmented reality vehicle navigation, the relative pose relationship between onboard cameras with non-overlapping fields of view cannot be accurately determined, affecting navigation accuracy and driving safety.

Method used

Images are acquired by the first shooting device, the second shooting device, and the relay shooting device. By using the movement of the calibration plate and feature point matching, combined with the stereo correction algorithm, the relative pose relationship between the devices is determined, and a continuous relative pose chain is constructed to achieve accurate positioning that aligns with information outside and inside the vehicle.

Benefits of technology

Accurately determining the relative pose relationship between vehicle-mounted cameras improves the accuracy of vehicle navigation and driving safety, enabling spatial positioning and real-time monitoring of users and objects.

Abstract

This application provides a method for determining the pose of a shooting device, an electronic device, and a storage medium. The method includes: determining a first relative pose between a first shooting device and a relay shooting device based on a first calibration image of a calibration board at a starting position, wherein the position and field of view of the relay shooting device are adjusted accordingly as the calibration board moves; determining a second relative pose between the relay shooting devices before and after each movement of the calibration board based on a second calibration image captured by the relay shooting device of the calibration board at each movement; determining a third relative pose between the relay shooting device and the second shooting device based on a third calibration image of the calibration board entering the field of view of the second shooting device; and determining the relative pose relationship between the first and second shooting devices based on the first, second, and third relative poses. Using the above method, the relative pose relationship between the shooting devices can be accurately determined.
