Based on the above computing device, a flowchart of a method for verifying validity of information point collection according to an embodiment of the present invention is shown in fig. 2, and mainly includes the following steps S201 and S202, which are described in detail as follows:
s201, before or when shooting is started, the shooting direction of a terminal used for shooting is detected.
In an embodiment of the present invention, the detection of the shooting direction of the terminal used for shooting can be realized by the following steps Sc2011 and Sc 2012:
and Sc2011, acquiring direction information of the terminal used for shooting when shooting, wherein the direction information comprises an azimuth angle and a pitch angle of the terminal used for shooting when shooting.
Taking the example that the terminal used for shooting is a smart phone, the azimuth angle and the elevation angle of the terminal used for shooting are obtained through a direction sensor (orientation sensor) of the smart phone during shooting, and a coordinate system of the direction sensor is a three-dimensional coordinate system, as shown in fig. 3-a, wherein a z axis is an azimuth angle pointing to the center of earth, the azimuth angle represents north, south, east and west of a geographic position, the range of the azimuth angle is 0 ° to 360 °, an x axis is the elevation angle, the range of the elevation angle is 0 ° to 90 °, 0 ° represents that the mobile phone is horizontally placed, and 90 ° represents that the mobile phone is vertically placed.
It should be noted that in the embodiments of the present invention, the direction sensors are not necessarily hardware entities, and it is possible that the software-based sensors do not depend on physical devices, although they are modeled after hardware-based sensors. Software-based sensors typically acquire data through one or more hardware sensors and sometimes call for virtual or manual sensors, etc., linear acceleration sensors and gravity sensors being examples of software-based sensors.
On the other hand, considering that the time delays of different accuracy types of direction sensors are different when acquiring the direction information of the direction sensors, a low time delay means more frequent detection and more power consumption. According to the empirical value, in the embodiment of the present invention, the direction sensor that takes about 500 milliseconds to 800 milliseconds from the time when the shooting button is clicked to the time when the imaging is completed may be selected as the direction sensor in the embodiment of the present invention, and therefore, about 10 sets of direction information of the direction sensors with a delay of 60 milliseconds may be acquired every shooting, and the 10 sets of direction information are averaged to be calculated as the final direction information.
And Sc2012, checking the azimuth angle during shooting to judge whether the azimuth angle during shooting is in a preset shooting interval.
As an embodiment of the present invention, verifying the azimuth angle during shooting to determine whether the azimuth angle during shooting is within the preset shooting interval may be implemented through the following steps S1 to S3:
s1, obtaining the target shooting point P closest to the current position of the terminal used for shooting in the target shooting point set0And the immediate neighbors P in the target shooting point set0Front and back or right and left target shooting points P1And a target shooting point P2The latitude and longitude information.
In the embodiment of the present invention, the target photographing points may be grouped into one set, for example, for the target photographing points P4, P5, P6, P7 and P9, the one set into which the target photographing points are grouped may be { P4, P5, P6, P7, P9}, where P4 and P6 may be regarded as target photographing points before and after or around P5, and P6 and P9 may be regarded as target photographing points before and after or around P7.
In the embodiment of the present invention, a manner or method for obtaining a target shooting point closest to a current position of a terminal used for shooting may beReferring to the method or method in step Sb2012 of the previous embodiment, let the target shooting point closest to the current position of the terminal be P0The target shooting point set is positioned at P0Front and back or left and right target shooting points are P1And P2。
S2, according to the target shooting point P0、P1And P2Calculating origin and P 'on the plane rectangular coordinate system to which the target shooting point is mapped'2The included angle x, P 'between the connecting line and the x axis or the y axis of the plane rectangular coordinate system'2Is the target shooting point P2Mapping to one point in four quadrants of the plane rectangular coordinate system.

For example, if the detection result is not in accordance with the preset value by detecting the shooting direction, prompt information such as "shooting failure, abnormal shooting direction, please aim at the shooting direction" or "shooting failure, abnormal angle, please keep the mobile phone perpendicular to the ground as much as possible, do not take a downward shot and do not take an upward shot" is popped up, and the like.
It can be known from the method for verifying the validity of information point collection illustrated in fig. 2 that the shooting direction of the terminal used for shooting is detected before or at the beginning of shooting, and since the detection is performed in real time, when the shooting direction is detected to be inconsistent with the preset value, an illegal prompt message for information point collection is popped up, so that the user can be timely reminded of the unconscious shooting non-specification, and the cost increase caused by re-shooting is reduced.
In the embodiment of the invention, the method further comprises the steps of detecting the software environment of the terminal used for shooting; if the detection result of the software environment does not match the preset value, popping up prompt information that the information point acquisition is illegal, for example, popping up prompt information such as "detecting that the virtual positioning App is installed, please unload and shoot" and detecting the software environment of the terminal used for shooting can be realized through the following steps Sa2011 and Sa 2012:
sa2011 acquires information of an installed application in the terminal.
In the Android Application Framework layer (Application Framework), many service management classes are provided, wherein the main responsibility of the Package Manager management class is to manage Application packages. In the embodiment of the present invention, when entering the photo shooting page, information of all installed applications, such as names of the installed applications, names or IDs of installation packages of the installed applications, and the like, on a terminal (e.g., a smartphone) used for shooting is acquired by calling an Application Program Interface (API) provided by a Package Manager.
Sa2012 determines whether or not the virtual positioning software is installed in the terminal based on the information of the application installed in the terminal.
It should be noted that, in the embodiment of the present invention, the user may refer to a user of the map panning software. At present, one of the cheating means of users is to simulate and position coordinates of a terminal used for shooting by a smart phone and the like to a target shooting point, such as a position near a target street, and the actual position of the user is on another street by using virtual positioning software, so that the shot POI data is false data. In order to ensure that the shooting coordinates of the user are real and effective, when the user enters a shooting page for the first time, whether the virtual positioning software is installed in the terminal can be judged according to the information of the installed application program in the terminal used for shooting. The specific method may be to compare the information of the application installed in the terminal used for shooting with the information of the known virtual positioning software, and if the information of the application installed in the terminal used for shooting matches with the information of the known virtual positioning software, determine that the virtual positioning software is installed in the terminal used for shooting. The following table is known virtual positioning software and its information.

Figure BDA0001554893580000151
Further, considering that the virtual positioning software generally relates to some gray industries, the application update speed is high, and in order to ensure that the information of the virtual positioning software is updated timely, in the embodiment of the present invention, the server is adopted to maintain the information list of the virtual positioning software and dynamically issue the information list to the terminal for shooting, so that the terminal for shooting always stores the latest information list of the virtual positioning software, so that the information of the application program installed in the terminal for shooting can be compared with the latest information of the virtual positioning software, and whether the virtual positioning software is installed in the terminal for shooting is determined.
In an embodiment of the present invention, the method further includes: detecting the shooting distance of a terminal used for shooting; if the detection result of the shooting distance does not meet the preset value, popping up an information point to collect illegal prompt information, for example, popping up prompt information such as "too close distance, please approach to shooting", and detecting the shooting distance of the terminal used for shooting can be realized through the following steps Sb2011 to Sb 2013:
sb2011, longitude and latitude information of the current position of the terminal used for shooting is acquired.
In the embodiment of the invention, the latitude and longitude information of the current position of the terminal used for shooting can be obtained through the positioning function module in the terminal used for shooting.
Sb2012 calculates the distance D between the current position of the terminal used for shooting and the target shooting point according to the latitude and longitude information of the target shooting point and the latitude and longitude information of the current position of the terminal used for shooting.
It should be noted that, in the map panning software, the street scanning task Line displayed on the task map is composed of a longitude and latitude coordinate set issued by the server, in other words, the target shooting point includes longitude and latitude information, such as longitude and latitude coordinates. And calculating the distance D between the current position of the terminal for shooting and the target shooting point according to the longitude and latitude information of the target shooting point and the longitude and latitude information of the current position of the terminal for shooting. The specific method can be as follows: according to the formula

and haversin (Δ λ) can be obtained by the formula haversin θ ═ 1-cos θ)/2.
Sb2013, compares the distance D with a preset distance, and determines whether the shooting distance meets the specification according to the comparison result.
In order to prevent the user from shooting too far away from the target shooting point, for example, the target street, the shooting distance must be limited to a specified interval. According to experience and actual data acquisition analysis, the preset distances are set to be different in different shooting stages, and the specific limiting strategies are as follows:
when shooting is started, the distance D between the current position of the terminal and a target shooting point during first shooting is within 50 meters, namely, the preset distance can be set to be 50 meters when shooting is started;
in the shooting process, the distance D between the current position of the terminal and the target shooting point is within 100 meters at most when shooting each time, namely the preset distance can be set to be 50 meters in the shooting process;
when the shooting is completed, the distance D between the current position of the terminal and the target shooting point in the last shooting is within 50 meters, that is, when the shooting is completed, the preset distance may be set to 50 meters.
According to the limiting strategy, according to the result of comparing the distance D with the preset distance, when shooting is started, if the distance D between the current position of the terminal and the target shooting point is smaller than 50 meters during the first shooting, the shooting distance is determined to be in accordance with the regulation, otherwise, the shooting distance is not in accordance with the regulation; in the shooting process, if the minimum value of the distance D between the current position of the terminal and the target shooting point is less than 100 meters in each shooting process, determining that the shooting distance meets the regulation, otherwise, determining that the shooting distance does not meet the regulation; and when shooting is finished, if the distance D between the current position of the terminal and the target shooting point in the last shooting is less than 50 m, determining that the shooting distance meets the specification, otherwise, determining that the shooting distance does not meet the specification.
In an embodiment of the present invention, the method further includes: detecting a shooting gland of a terminal used for shooting; if the detection result of the covering of the shot does not accord with the preset value, an information point is popped up to collect illegal prompt information, for example, prompt information such as 'continuously covering the future with the previous picture and please shoot again' is popped up. The term "cover" means that two photographs taken consecutively have a recognizable overlap. The detection of the shooting cover of the terminal used for shooting can be realized through the following steps Sd2011 to Sd 2014:
sd2011, matching two taken pictures.
And Sd2012, if the matching result is smaller than a preset ideal threshold value, determining that the gland exists between the two taken pictures.
And Sd2013, if the matching result is larger than a preset ideal threshold and smaller than or equal to an early warning threshold, uploading the two shot pictures to a server, and judging whether the two shot pictures have covers by the server.
And Sd2014, if the matching result is greater than the early warning threshold value, determining that no gland exists between the two taken pictures.
