Problems solved by technology

However, the existing positioning and navigation technology has the following deficiencies in practical application: (1) outdoor positioning accuracy is generally at the meter level, further improving positioning accuracy requires signal enhancement technology, and the cost increases; (2) indoor positioning is difficult due to lack of satellite signals More road test equipment must be deployed, and vehicle positioning equipment needs to be installed on the object to be positioned. This positioning method has poor positioning accuracy and high cost, which has become an important factor restricting the development of automatic parking, parking space positioning and other fields.
The above applications all involve intelligent parking technology for self-driving vehicles, but they do not pay much attention to the positioning accuracy and positioning cost mentioned above

Embodiment 1

[0041] like figure 1As shown, the regional positioning and navigation system based on the traffic sign information line of this embodiment includes the traffic sign information line 100 containing distance and position information, the video acquisition unit 600, the control unit 700 and the mobile unit 500, wherein the traffic sign information line 100 is laid on the road in the area, and the video acquisition unit 600 and the control unit 700 are installed on the mobile unit 500; when the mobile unit 500 moves in the area, the video acquisition unit 600 collects the image of the traffic sign information line 100, and the control unit 700 recognizes and calculates The location information and moving distance of the point are obtained, and the navigation of the mobile unit 500 is realized in combination with the electronic map of the area. figure 1 In the specific position A 200 and the specific position B 201, the binary code information line 400 is installed, and the equidis...

Embodiment 2

[0053] The regional positioning and navigation system based on the traffic sign information line of the present embodiment, such as Figure 4 The application scenario of the underground parking lot is shown in the figure. In the underground parking lot, equidistant information lines 300 are laid along both sides of the road in the parking lot. All parking spaces and other key points such as elevator entrances, garage entrances and exits, and different driveways A binary code information line 400 is laid, and the binary code corresponding to each position is unique. The underground parking lot is equipped with a parking space status monitoring system. The real-time status information of the parking space and the electronic map of the parking lot are all stored in the cloud background. In this embodiment, the mobile unit 500 is a vehicle with an automatic driving function, and there are built-in video cameras around the vehicle body. When the car owner drives the mobile unit 50...

Embodiment 3

[0055] The regional positioning and navigation system based on the traffic sign information line of the present embodiment, such as Figure 5 The application scenario of on-street parking space inspection is shown in the figure. The roadside parking charging system usually installs a parking space detector on the parking space to detect the state change of the parking space, and uses a video patrol car to collect the vehicle license plate information on the parking space, and then links the parking space status information with the license plate information through the patrol car positioning , forming a charging order. In this embodiment, the traffic sign information line 100 is used to collect and identify information, such as Figure 5 As shown, the traffic sign information line 100 is also installed on the regional road of the parking space, and the parking space line 400 including the parking space of each roadside parking space 204 is laid with a binary code information ...

Abstract

The invention discloses an area positioning navigation system based on traffic sign information lines and a working method thereof, and belongs to the field of positioning and navigation. The positioning navigation system comprises a traffic sign information line containing distance and position information, a video acquisition unit, a control unit and a mobile unit, wherein the traffic sign information line is laid on an area road, and the video acquisition unit and the control unit are installed on the mobile unit; when the mobile unit moves, the video acquisition unit acquires an image of the traffic sign information line, the control unit identifies and calculates the position information and the moving distance of the point, and the navigation of the mobile unit is realized in combination with an electronic map. The method overcomes the current situation of high cost of vehicle positioning navigation in the prior art, realizes high-precision and low-cost positioning navigation in an area by combining a large number of traffic marker lines laid in a city with a video recognition technology which is maturely applied at present, and can be applied to the fields of automatic driving, automatic parking and the like.

Description

technical field [0001] The invention relates to the technical field of positioning and navigation, more specifically, to an area positioning and navigation system based on traffic sign information lines and a working method thereof. Background technique [0002] The development of positioning and navigation technology has greatly changed people's travel experience. Technologies such as satellite navigation, base station positioning, and UWB positioning have been widely used in object positioning, vehicle navigation, and automatic driving. But the existing positioning and navigation technology has the following deficiencies in practical application: (1) Outdoor positioning accuracy is generally at the meter level, further improving positioning accuracy requires signal enhancement technology, which increases the cost; (2) Indoor positioning is difficult due to lack of satellite signals More road test equipment must be deployed, and vehicle-mounted positioning equipment needs t...
