Digital panorama based three-dimensional indoor ranging system and device

Abstract

The invention discloses a digital panorama based three-dimensional indoor ranging system and device. The digital panorama based three-dimensional indoor ranging system comprises a panoramic client and a panoramic server; the panoramic client is used for displaying a digital panorama for a user, capturing coordinates of two points on the digital panorama and transmitting the coordinates of the two points on the digital panorama to the panoramic server, wherein the two points on the digital panorama are selected by the user; the panoramic server is used for transforming the coordinates of the two points on the digital panorama into coordinates of two corresponding points on an indoor space presented by the digital panorama and calculating the distance between the two points on the indoor space according to the coordinates of the two points on the indoor space. According to the digital panorama based three-dimensional indoor ranging system and device, the actual distance between any two points in the digital panorama on the actual indoor space can be accurately calculated and accordingly the accurate ranging on the indoor space in the digital panorama is implemented and the user can fully feel and understand the distance and size information of the indoor space displayed through the digital panorama conveniently.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a three-dimensional indoor ranging system and equipment based on digital panorama. Background technique [0002] A digital panorama is a wide-angle view of a scene, either as an image or as a video. A digital panorama can be (but need not be) a full 360-degree horizontal view of a scene (i.e., the cylindrical type), or a full 360-degree horizontal view of a scene plus a 180-degree vertical view (i.e., a spherical Types of). The scene it shows can be the real physical space of shooting, or it can be the virtual space being rendered. The scene data of the digital panorama can be prepared before being browsed, or can be generated in real time while being browsed. The digital panorama can give the viewer an immersive navigation experience, that is, give the viewer an immersive 3D viewing experience. [0003] Digital panoramas generally provide viewers with the following tw...

Problems solved by technology

However, in the prior art, the user can only simply view the house through the digital panorama, and the user cannot grasp the distance and scale of the space displayed by the digital panorama in the process of viewing the house.

The spatial distance displayed by the digital panorama is visually abstract to the user, and the spatial distance can only be estimated through imagination, experience, etc., which often does not match the actual spatial distance
