Embodiment Construction

[0034] The technical scheme of the present invention will be further described in detail below in conjunction with implementation examples and drawings.

[0035] Such as figure 1 As shown, a positioning method for indoor automatic parking includes the following steps:

[0036] Step one, spray grid on the indoor parking lot road, the grid uses binary coding. Using 32-bit binary coding, the main part has 32 grids, a grid size of 25cm*25cm, the road width that can be expressed is 32*0.25=8 meters, and the road length that can be expressed is 2 32 *0.25=2 30 Meters, the expressible area is 8*2 30 = 2 33 Square meters, about 8590 square kilometers. The grid is sprayed in black and white, black represents the binary number 1, and white represents the binary number 0. Set the start bit, stop bit and check bit. The start bit is black, set to "1", and the end bit is white, set to "0". The even parity bit is used so that the number of "1"s between the start bit and the stop bit is always ...

Abstract

The invention discloses a positioning method for indoor automatic parking. The positioning method comprises the following steps: (1) spraying grids on an indoor parking lot road, wherein the grids adopt binary coding; (2) entering binary digit sequences corresponding to actual locations into a GIS database; (3) shooting photos of the grids on the ground by using a camera and uploading the photos to a server; (4) identifying grid information, and reading out a binary digit sequence; (5) finding, through searching, an actual location of a vehicle in the GIS database based on the output binary digit sequence. According to the method, the techniques of computer vision, location coding, location service and the like are combined; after location data is stored into the database, binary ID information is obtained by identifying a drawn grid, so that the use is convenient and fast, the positioning precision is relatively high, vehicle positioning can be performed indoors accurately and reliably, and the application range is wide.

Description

Technical field [0001] The invention relates to a method for parking a vehicle, in particular to a positioning method for indoor automatic parking. . Background technique [0002] With the continuous progress of science and technology, indoor positioning technology continues to develop, including Bluetooth indoor positioning technology, infrared indoor positioning technology, ultra-wideband indoor positioning technology, Zigbee indoor positioning technology, WiFi indoor positioning technology, etc. However, these technologies are inconvenient to use and cannot meet the positioning needs of automatic parking. Therefore, there is an urgent need for a stable, accurate and convenient positioning method for indoor automatic parking. Summary of the invention [0003] Objective of the invention: In view of the problems in the prior art, the objective of the present invention is to provide a positioning method for indoor automatic parking that is convenient to use and has high positioni...
