Therefore, how to improve the positioning accuracy without upgrading the existing device by hardware or structural modification is a technical problem to be urgently solved by those skilled in the art.
In view of the above technical problems, an embodiment of the present invention provides a positioning method. Fig. 1 is a schematic flow chart of a positioning method provided by the present invention. As shown in fig. 1, the method includes:
it should be noted that the current positioning information is obtained based on positioning of a GPS device or a beidou device of the current vehicle, and the current positioning information may include longitude and latitude coordinates, signal strength, or the number of satellites of the current vehicle, which is not limited in the embodiment of the present invention.
In view of the fact that wireless devices are installed in existing sharing vehicles and used for receiving messages sent by a server or a user terminal application program and sending messages to the server or the user terminal application program, in the embodiment of the invention, communication is established among the wireless devices in the sharing vehicles, positioning information is shared with each other, a cellular network is established, and the positioning information in the cellular network is used for correcting the self-positioning information.
Specifically, the wireless network device of the current vehicle may scan the shared vehicle within the coverage of the wireless network device to obtain the scanned and obtained surrounding shared vehicle, establish communication with the surrounding shared vehicle, obtain the positioning information of the surrounding shared vehicle after the communication connection, and correct the positioning information of the current vehicle according to the current positioning information of the current vehicle and the positioning information of the surrounding shared vehicle after the current vehicle receives the positioning information of the surrounding shared vehicle to obtain the current revised position information. The wireless network may be bluetooth, WIFI, radio frequency communication, and the like, which is not limited in this embodiment of the present invention.
It should be noted that the present invention is not limited to this, and the present invention may correct the own positioning information according to the current positioning information of the own and the positioning information of the surrounding shared vehicle, or correct the own positioning information according to the corrected positioning information of the surrounding shared vehicle after the positioning information of the surrounding shared vehicle is corrected in a recursive manner. After the communication connection, the obtaining of the positioning information of the surrounding shared vehicle may be that the surrounding shared vehicle actively broadcasts the positioning information of the surrounding shared vehicle after the communication connection, or that the surrounding shared vehicle requests the positioning information of the surrounding shared vehicle after the communication connection, and the surrounding shared vehicle returns the positioning information of the surrounding shared vehicle to the current vehicle as a response after receiving the request.
In addition, the location information of the neighboring shared vehicle is corrected based on the location information of the neighboring shared vehicle, and when only one neighboring shared vehicle exists, the corrected location may be calculated according to the location information of the neighboring shared vehicle in combination with the radius of the coverage area of the wireless network, and considering that the coverage area of the wireless network is generally 10 meters to 20 meters, the location information of the neighboring shared vehicle may also be directly used as the current revised location information of the current vehicle, which is not limited in the embodiment of the present invention. When there are two neighboring shared vehicles, the midpoint of the position information of the two neighboring shared vehicles may be used as the revised position information of the current vehicle, and the point on the midperpendicular of the connection line of the position information of the two neighboring shared vehicles, which is closest to the current vehicle, may also be used as the current revised position information. When there are multiple (more than 2) surrounding shared vehicles, the center point may be determined according to a point closest to the current vehicle positioning information in the intersection points of the respective coverage areas of the surrounding shared vehicles, as the current revised position information of the current vehicle, and according to the minimum abscissa and the maximum abscissa, and the minimum ordinate and the maximum ordinate in the positioning information of the surrounding shared vehicles, and the center point is used as the current revised position information of the current vehicle, which is not limited in the embodiment of the present invention.
According to the positioning method provided by the embodiment of the invention, the peripheral shared vehicles are scanned and obtained through the existing wireless network equipment of the vehicle, the self positioning information is corrected according to the positioning information shared by the peripheral shared vehicles, the wireless cellular network based on temporary construction is realized, the self positioning information is corrected by applying the positioning information of the peripheral shared vehicles, the corrected positioning information is more accurate, the positioning precision is improved, the vehicle hardware or structure and the like are not required to be modified, and the upgrading and modifying cost is saved.
Based on the above embodiment, step 140 includes:
if the distance between the current positioning information and the positioning information is larger than a preset threshold value, determining the current revision position information based on the current positioning information and the positioning information; otherwise, the current positioning information is used as the current revision position information.
In consideration of the wireless network coverage of the wireless network device, it can be known that other vehicles scanned by the current vehicle wireless network device are necessarily in the wireless network coverage of the current vehicle wireless network device, and therefore whether the current positioning information of the current vehicle needs to be corrected or not can be judged through the wireless network coverage.
Specifically, if the distance between the current positioning information and the positioning information of the other vehicles is greater than a preset threshold, it is determined that the current positioning information needs to be corrected, and a current revised position is calculated according to the positioning information of the other vehicles scanned by the current vehicle, and if the distance is less than or equal to the preset threshold, it is determined that the current positioning information does not need to be corrected, and the current positioning information can be directly used as the current revised position.
It should be noted that the preset threshold may be set according to a maximum radius of a wireless network coverage of the wireless network device. Meanwhile, considering that there may be a plurality of surrounding shared vehicles, when there are a plurality of surrounding shared vehicles, that is, when there are a plurality of positioning information of the surrounding shared vehicles, the current positioning information and the positioning information of the surrounding shared vehicles calculate distances one by one, and when there is a distance greater than a preset threshold, it is determined that the current positioning information needs to be corrected.
Based on the above embodiment, step 140 includes:
step 141, determining the number of surrounding shared vehicles;
step 142, if the number of the surrounding shared vehicles is greater than 2, determining a minimum abscissa, a maximum abscissa, a minimum ordinate and a maximum ordinate based on the positioning information of each shared vehicle in the surrounding shared vehicles; and determining current revision location information based on the current location information and the center point determined by the minimum abscissa, the maximum abscissa, the minimum ordinate, and the maximum ordinate.
Considering that the number of scanned surrounding shared vehicles is uncertain, and different numbers need different processing methods, the embodiment of the present invention needs to acquire the number of surrounding shared vehicles before revising the current positioning information, and then perform corresponding correction logic according to the number of surrounding shared vehicles.
Specifically, the number of scanned surrounding shared vehicles is determined, when the number of the surrounding shared vehicles is greater than 2, the minimum abscissa, the maximum abscissa, the minimum ordinate and the maximum ordinate in the positioning information of the surrounding shared vehicles are obtained according to the positioning information of the surrounding shared vehicles, the abscissa of the central point is determined according to the minimum abscissa and the maximum abscissa, the ordinate of the central point is determined according to the minimum ordinate and the maximum ordinate, and finally the current revision position information is determined according to the central point and the current positioning information.
It should be noted that the position information of the central point may be directly used as the current revision position information, and the position information of the central point and the midpoint position information of the current positioning information may also be used as the current revision position information, which is not limited in this embodiment of the present invention.
Based on the above embodiment, step 141 further includes:
and if the number of the surrounding shared vehicles is 2, connecting the positioning information of the surrounding shared vehicles, and determining the current revised position information based on the middle vertical line of the connecting line and the current positioning information.
Specifically, when the number of the surrounding shared vehicles is 2, connecting coordinates in the positioning information of the surrounding shared vehicles, determining a perpendicular bisector of the connecting line, and obtaining current revised position information through the perpendicular bisector and the current positioning information.
It should be noted that, the current revised position information is obtained through the perpendicular bisector and the current positioning information, the coordinate position information closest to the current positioning information on the perpendicular bisector is obtained through calculation according to the coordinates in the perpendicular bisector and the current positioning information, and the coordinate position information is used as the current revised position information label, or the intersection point position information of the perpendicular bisector and the connecting line is directly used as the current revised position information, that is, the midpoint position information of the connecting line is used as the current revised position information, which is not limited in the embodiment of the present invention.
Based on the above embodiment, step 141 further includes:
if the number of the surrounding shared vehicles is 1, determining the current revised position information based on the error value, the signal strength and the number of available satellites in the positioning information of the surrounding shared vehicles and the error value, the signal strength and the number of available satellites in the current positioning information.
Specifically, when the number of the surrounding shared vehicles is 1, more reliable positioning information of the two positioning information is selected as the current revised position information according to an error value, signal strength, and the number of available satellites in the positioning information of the surrounding shared vehicles and an error value, signal strength, and the number of available satellites in the current positioning information.
It should be noted that the more reliable positioning information of the two positioning information may be determined at least according to a comparison result of one item of an error value, a signal strength and a number of available satellites in the positioning information of the surrounding shared vehicle and the current positioning information, wherein a smaller error value indicates more reliable, a stronger signal strength indicates more reliable, and a greater number of available satellites indicates more reliable.
