Invention name: A passenger positioning method and system

Technical field

[0001] The present invention relates to the field of urban transportation, and in particular, to a passenger positioning method and system.

Background technique

[0002] Taxi software has changed the traditional way of taxiing, and established and cultivated the modern mobile travel mode that users led by the big mobile Internet. Compared with traditional telephone recruiting and roadside recruiting, the birth of taxi software has changed the traditional taxi market pattern, subverting the concept of roadside blocking, using the characteristics of mobile Internet, integrating online and offline, from taxi From the initial stage to getting off the bus, paying the fare on the line, changing the traditional taxi driver and other passenger modes, allowing the driver to "take orders" according to the passenger's destination, saving the driver and passenger communication costs, reducing the vacancy rate, and maximizing the savings of both sides. Resources and time.

technical problem

[0003] After a passenger places an order, how quickly the driver picks up the driver poses a great challenge. Currently, smart navigation drivers can quickly know the approximate location of a passenger, but the location is not accurate enough. For example, if a passenger takes a taxi in a strange place, he does not know how to describe his specific location. Therefore, he is on the left side of a street. Because the satellite positioning error is generally within 10 meters, the passengers are on the map. It is on the right side of the street. This time, the driver often needs to go around a long way. Therefore, it is difficult for a driver to find a passenger with a simple address after positioning. In some cases, even the driver is very close to the passenger but they can't find each other. Even if the driver confirms the phone, it may not be able to find the passenger accurately, so that the driver may circle around the destination to find the passenger after arriving at the destination. In order to improve efficiency, how to quickly and accurately pick up the driver becomes a problem to be solved.

BEST MODE FOR CARRYING OUT THE INVENTION

[0015] The solution of the present invention will be described in detail below in conjunction with the preferred embodiments thereof.

[0016] As shown in FIG. 1, the method in this embodiment includes the following steps:

[0017] S101: Obtain a rough location of the user.

[0018] The user snores the taxi software, the taxi software obtains the rough position of the user according to the positioning system (GPS, Beidou), and can automatically generate the corresponding address name, because the range indicated by an address name may be very large (such as a bus) The name of the station, most of which does not know which side of the bus stop), may cause the driver to travel a long way when picking up passengers. After obtaining the user's current rough position, the system obtains the possible boarding positions within the preset range. These possible boarding positions are generally the empirical values obtained by the passenger after multiple rides. In most cases, passengers are unlikely to be very familiar with the name of the boarding and disembarking location and the scene pictures they can see. This results in the inability to accurately reach the destination even after the user knows the name of the best boarding location. Ground. It is also possible that the user sees the corresponding scene but cannot get the corresponding location name.

[0019] acquiring a possible boarding position in the first preset range according to the coarse position, and acquiring a scene picture corresponding to each possible boarding position.

[0020] After the system obtains the possible boarding position within the first preset range, the user can see the corresponding location name of the corresponding road section on the map. In general, after GPS positioning, the system will provide several locations around its location as possible on-board location (or recommended on-board location). The corresponding scene picture can be preset on the possible boarding position on the system. In this way, when the possible boarding position is obtained, it can acquire the scene picture corresponding to each possible boarding position and display it to the user for selection. The scene picture here consists of two or more pictures taken at different shooting angles at the possible boarding position. The different shooting angles include at least the first shooting angle and the second shooting angle. Of course, in a relatively simple traffic environment, only one picture of the shooting angle may be used as the scene picture.

[0021] S103: The user selects one of the scene pictures according to the currently seen scene of the scene; and obtains the optimal boarding position of the user according to the selected scene picture.

[0022] Pre-save the scene picture in the server, and obtain a plurality of groups of pre-stored scene pictures within the preset position of the user (for example, within 100 meters) by using the current rough position information of the user. After displaying the images of the pre-stored scenes to the user, the user can compare with the scenes (ie, the real scenes) that can be seen at the current location, and it is not difficult to find the surroundings and the current scene images. Close to the picture, the user can select a scene picture that is close to the scene that he or she sees according to the currently selected scene selection. Through system comparison, it is possible to roughly generate the current user's location. In some places where the traffic environment is simple, a scene picture can relatively clearly locate the user. In a more complex traffic environment, the positioning effect of an image will be greatly weakened.

[0023] As a better example of implementation, the pre-stored scene picture here is a scene picture taken using different angles. Due to the certain error of satellite positioning accuracy, most mobile phone positioning can only locate one street. It is difficult to accurately locate which side of the street, which increases the difficulty of pick-up and drop-off for taxi drivers. And compare with the system picture, can more accurately know the user's location, solve the inconvenience caused by traditional satellite positioning. In general, the direction of the picture can be obtained by comparing the pre-stored picture with the angle picture. The direction of the camera and the reference is the direction of the picture (the direction from the camera to the reference object in the plane). The method for obtaining a user's best boarding position by using a scene picture includes: obtaining a first direction of a first shooting angle picture, and acquiring a second direction of the second shooting angle picture; determining according to an intersection of the first direction and the second direction The user's best boarding location. Here, the first shooting angle picture and the second shooting angle picture are pre-stored scene pictures (ie, a combination of multiple pre-stored pictures) can be pre-stored by the system and displayed to the user for selection. In order to achieve better technical results, due to the user's pre-existing scene picture, the lighting conditions are different due to weather and daytime factors. Therefore, the scene picture 吋 must be called differently according to the uploaded time and the weather of the time, so that the user does not select the wrong picture because of different scene pictures appearing in different days.

[0024] As shown in FIG. 2, the user A is at the bottom of the street, and the second user B is at the other side of the street; A sees the reference A, the reference B, the reference C at the current position, and then at the mobile terminal or other Electronic device selection Reference A and reference B are similar to the picture at position A (apparently the picture of the same reference seen in both positions of A and B will be different). In this way, the first direction of the reference object A吋 can be respectively obtained (the direction of the pointing object A is directed to the reference object A, the present embodiment expresses the direction in the form of a straight line, and so on), and the second direction of the reference object B is photographed. The intersection of the directions (ie, the intersection of the inverse extension lines of the camera direction) determines the current position of A. Similarly, the current position of B can also be obtained by this method. Here, the current position of A can be determined theoretically in two directions. The third direction of acquisition of the reference object C吋 can be used for calibration. The third direction can be obtained by the user taking the reference object C at the current position and uploading it to the server. The server pre-stores the panoramic picture or the marker picture, and the third direction can be calculated by comparing the picture with the picture C of the reference object. . The method of calibrating with the third direction calibration is: determining whether the first direction, the second direction, and the third direction intersect at one point, and if so; using the point as the exact coordinate of the current A (or B). If not, the intersection points of the first direction, the second direction and the third direction may form a triangle, and the center of gravity of the triangle (according to the actual situation, the center of gravity here may also be replaced by the outer center, the inner center, the center of the triangle Or next to) as the coordinates of the current A (or B). In the case of a triangle, it indicates that the current position of the user is deviated from the shooting position of the pre-existing server. After the user selects the pre-stored scene picture, the position can be proved to be relatively close to the precise coordinate in the current pre-existing system. The center of gravity of the triangle allows a combination of the user's actual coordinates and the precise coordinates in the pre-existing system, which in turn makes the calibrated coordinates closer to the true coordinates. By such a more precise positioning, after receiving the rough position information of the passenger, the taxi locator can quickly know which side of the street the passenger is on, thereby saving the time for finding the passenger.

As shown in Figure 3, A is in the current position and uses the first scene picture (A can be selected from the same first scene picture near the selected position), the first shooting angle picture after shooting A and the second The shooting angle picture is uploaded to the server. The system compares the similarity between the first scene picture and the first shooting angle picture, and can compare the position of the shooting position in the first scene picture, and then can convert the first direction; similarly, the system is based on the first The second direction can be converted by comparing the similarity between the scene picture and the second shooting angle picture. The panoramic picture corresponding to the first scene picture is displayed on the display or the mobile phone as a rectangular image, and the length of the rectangle is divided by 360, and the partial picture corresponding to each angle; and the shooting device used by the user also has a corresponding lens angle 150. °; The first shooting angle picture is also rectangular after shooting, and the length of the rectangle is divided by 150, you can get a partial picture corresponding to each angle; Comparing 1° in the first shooting angle picture with 1° in the first scene picture, the similarity can be determined relatively quickly; as a test, the picture of the first shooting angle picture and the first scene picture are collected multiple times For comparison, the intermediate value of the first shooting angle picture 75° is taken as the corresponding direction of the first shooting angle direction, and only 1° of data can be taken. Since the entire captured picture is a parallel plane, the directions of the respective points are parallel, and the intersecting points are shown as planes, and from the three-dimensional view, the two faces intersect.

[0026] In order to make users, taxi platforms and businesses get better economic benefits. After the user obtains the positioning information by using the above scheme, the advertisement mode and the advertisement-free mode can be adopted. In the advertisement mode, the merchant information in the second preset range of the user end position is obtained; and the related advertisement of the above-mentioned merchant information is embedded in the pre-stored scene image. Obtaining the business information in the second preset range of the user end position (or the rough position, that is, the current position); and displaying the corresponding business advertisement to the user, the user can further understand the business around the destination, and achieve accurate The purpose of advertising. The user's end position is the information of the starting point and the ending point of the user's taxi input. When the user goes to the destination, he or she will usually shop or do the corresponding business there. At this time, there is an advertisement of the corresponding merchant, which can help the user. Better understand some of the situation of the destination. In this mode, the user can reduce part of the ride cost, the advertiser can carry out appropriate advertisement placement, and the taxi platform can increase the revenue of the advertisement, and the user can be more preferentially increased to increase the user's stickiness to use the software.
