Description

technical field

[0001] The present invention relates to map information processing technology in the field of wireless communication, in particular to a method, system and terminal equipment for generating navigation information. Background technique

[0002] The current indoor navigation technology mainly has the following two solutions, wireless positioning and image recognition positioning. Among them, the principle of wireless positioning technology is to transmit signals through multiple signal transmitters in the wireless sensor network, and the terminal side calculates the received signal strength from the received signals through positioning calculations, and then obtains location information; or the sensor network receives signals uploaded by mobile terminals , calculate the received terminal signal strength through the positioning algorithm, and then obtain the terminal location information, and send the information to the terminal side. Image recognition and posi...
