Indoor parking lot guidance system and its map reconstruction method

Abstract

The invention provides an indoor parking lot parking space guidance system and a map reconstruction method. The system is characterized in that the system comprises parking space terminals corresponding to parking spaces respectively, at least three wireless APs, a server and a guidance indication board. On one hand, each parking space terminal is used for detecting occupation situation of the corresponding parking space; and on the other hand, the parking space terminal is connected with the at least three wireless APs and realizes coordinate position calibration of each parking space througha triangulation location method. The server finishes reconstruction of a parking space map according to the coordinate position information of each parking space, and meanwhile, controls the guidanceindication board to display corresponding guidance and indication information according to the parking space occupation situation. The beneficial effects are that, under the condition of having no indoor parking lot priori map, the parking lot parking space guidance map can be reconstructed based on the relative position information of a parking lot; and indoor parking lot parking space guidanceunder the condition of no GPS signal or weak GPS signal can be realized.

Description

technical field [0001] The invention relates to intelligent parking technology, in particular to an indoor parking space guidance system and a map reconstruction method thereof. Background technique [0002] With the development of the economy, car ownership has increased substantially, but parking spaces are extremely scarce. Difficulty in parking has always been a concern for car owners, especially in some international metropolises. In the case of such a large gap in parking spaces, the unreasonable construction of the parking lot or the disconnection of the parking space information has led to the situation that the utilization rate of the parking spaces in some parking lots is not high, which makes the problem of parking difficulties more acute, and for the parking lot For the operator, this situation increases operating costs and reduces revenue. [0003] In response to the above situation, some products related to intelligent parking systems have appeared both at ho...
