Abstract

The invention relates to the technical field of mobile communication, in particular to a map construction method, a map construction device, a computer readable medium and terminal equipment. The method is applied to a server side and comprises the following steps: receiving image data of a specified area uploaded by at least two sets of terminal equipment, wherein the terminal equipment is in communication connection with the server side; constructing a three-dimensional sub-map corresponding to each set of terminal equipment according to the received image data; and carrying out feature matching on the three-dimensional sub-maps, and carrying out feature fusion processing on the corresponding three-dimensional sub-maps when the feature matching of the three-dimensional sub-maps succeedsso as to obtain a target map. According to the method, the image data can be acquired by using a plurality of sets of terminal equipment, and the accurate target map can be established so that the mapping time can be effectively saved.

Description

technical field [0001] The present disclosure relates to the technical field of mobile communication, and in particular to a map construction method, a map construction device, a computer-readable medium, and a terminal device. Background technique [0002] With the continuous enrichment of augmented reality (Augmented Reality, AR) technology, it has been applied in many fields. For example, AR advertisements, AR games, AR social interaction, AR navigation, etc. [0003] Existing AR navigation technology generally requires pre-construction of large-scale maps with high accuracy. Radar and other equipment are generally used for data scanning when building maps, which is very time-consuming. During the user's practical navigation process, the user must always hold the mobile phone and use the camera to collect the current environmental information in real time, so as not to lose tracking. [0004] It should be noted that the information disclosed in the above background sect...
