Embodiment Construction

[0053] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0054]The current mobile phone Bluetooth positioning is through the iBeacon signal that can be obtained by the smart phone. The mobile phone is placed in the car and moves synchronously with the vehicle. The accuracy of mobile phone Bluetooth positioning can reach 1-3 meters, but it must rely on the activation of the mobile phone's Bluetooth function, the initial positioning speed is relatively slow, and the Bluetooth performance of different models of mobile phones varies greatly. correction.

Abstract

The invention relates to an indoor vehicle positioning method and device, computer equipment and a storage medium. The method comprises the steps of obtaining a to-be-detected image collected at the current moment, extracting vehicle features according to the to-be-detected image, and performing calculation according to the vehicle features to obtain first positioning data; obtaining a Bluetooth signal uploaded by the mobile terminal, and determining second positioning data according to the Bluetooth signal; obtaining fusion positioning data and speed of the vehicle at the last moment, and predicting according to the fusion positioning data and speed to obtain prediction positioning data of the vehicle at the current moment; and performing fusion calculation according to the prediction positioning data and any one of the first positioning data or the second positioning data to obtain fusion positioning data at the current moment. Fusion calculation is carried out through the prediction positioning data and any one of the first positioning data or the second positioning data to obtain fusion positioning data at the current moment, so that the positioning precision is improved, the positioning time delay is shortened, and the stability is higher.

Description

technical field [0001] The present application relates to the technical field of indoor positioning, in particular to an indoor vehicle positioning method, device, computer equipment and storage medium. Background technique [0002] With the increase in the number of passenger cars, the gap in parking spaces is getting bigger and bigger, and 30% of driving time is spent on parking and looking for parking spaces. Vehicle positioning and navigation systems can help drivers effectively improve parking efficiency and prevent drivers from wasting precious time in finding parking spaces. [0003] However, the current vehicle positioning is mainly realized through GPS (Global Positioning System, Global Positioning System). However, due to the poor signal of the GPS signal in the indoor parking lot, the positioning delay is relatively large, so the positioning error is relatively large. Contents of the invention [0004] Based on this, it is necessary to provide an indoor vehicl...
