Abstract

The present disclosure relates to a positioning method, device, electronic equipment and storage medium of a photographing equipment. The method is: when starting the augmented reality function, use the spherical mode to initialize, and use the preset spherical radius to roughly estimate the three-dimensional coordinate positions of the map points corresponding to each feature point, thereby saving initialization time and reducing user waiting time , further, when it is determined that the shooting device has been able to obtain enough parallax feature points, the smart device switches from the spherical mode to the map mode, and re-initializes the three-dimensional coordinate system in the map mode, and the scale of the three-dimensional coordinate system Scaled according to the spherical radius of the spherical mode corresponding to the previous frame. In this way, not only the loss of augmented reality function can be avoided, but also the smooth transition of the scale of the three-dimensional coordinate system between the map mode and the spherical mode is realized, which ensures the continuous use of the augmented reality function.

Description

technical field

[0001] The present disclosure relates to the field of video processing, and in particular to a positioning method, device, electronic equipment and storage medium for a shooting device. Background technique

[0002] With the development of technology, augmented reality technology has been more and more widely used. People use augmented reality technology to merge virtual images, videos, and 3D models into real scenes, and track and determine shooting equipment in real time according to user operations. location and orientation information, and based on this information, reality augmentation is realized.

[0003] Under related technologies, a camera is usually used as a shooting device, and it is necessary to establish a world three-dimensional coordinate system (hereinafter referred to as a three-dimensional coordinate system) in the initialization stage, and calculate the three-dimensional coordinate positions of each shooting map point (hereinafter referred...
