Abstract

The invention relates to the technical field of panoramic video processing, in particular to a method and a system for labeling and adding panoramic video. The annotation adding method of the panoramic video comprises the following steps: a camera coordinate system is established with a camera position as an initial origin; the coordinate transformation model of map coordinate system and camera coordinate system is established with the preset line segment as reference. The map coordinate information of the object is obtained, the annotation content with the map coordinate information of the object is associated, and displayed in the panoramic video. The annotation adding method and system of the panoramic video of the invention realize the annotation of static and dynamic objects in the panoramic video, the operation steps are simple, the corresponding storage structure is simple, and the retrieval speed can be greatly improved in the large data processing application.

Description

technical field [0001] The present invention relates to the technical field of panoramic video processing, in particular to a method and system for adding annotations to panoramic video. Background technique [0002] Panorama image (panorama), also known as 360° panorama technology, is a photo showing a super-large viewing angle of a scene or even a 360-degree complete scene range. What we are talking about here is a panoramic image, which is synthesized by software to capture the image information of the entire scene relative to the camera, and played with a special player, simulating the two-dimensional plane into a real three-dimensional space, so as to simulate and reproduce the scene the effect of the real environment. Panoramic images are stitched from multiple real-world images in different directions taken at a fixed point. Panoramic video is composed of panoramic image sequences with time correlation, from which a real panoramic scene can be obtained, and video fr...
