[0048] Example 1

[0049] Please refer to Figure 1 and Figure 2 The flowchart of a real-time positioning video generation method provided by the present application shown in the figure includes the following steps:

[0050] Receiving an information carrier and attribute information of the information carrier sent by a terminal device; the attribute information is obtained by parsing the information carrier by the terminal device; here, the type of the terminal device is, for example, a mobile phone, an iPad, or a protocol interface;

[0051] Extracting longitude and latitude information from the attribute information;

[0052] Sending the latitude and longitude information to a video server;

[0053] Receiving a video for positioning by changing the viewing angle; the video for positioning by changing the viewing angle is recorded by the video server by determining the initial position according to the latitude and longitude information, and taking the moment when the drawing of the initial position is completed as the recording time starting point;

[0054] Determining the type of the information carrier, if the information carrier is a photo, combining the photo with the perspective change positioning video to obtain a target video;

[0055] If the information carrier is not a photo, the perspective change positioning video is the target video;

[0056] Storing the target video in a database, and extracting a video link generated by the database;

[0057] The video link is sent to the terminal device.

[0058] In this embodiment, the method may be implemented by an intermediate server;

[0059] Specifically, the intermediate server receives the information carrier and the attribute information of the information carrier sent by the terminal device;

[0060] The type of information carrier is, for example, a photo, a latitude and longitude information string, a satellite image, or a location code POI; the photo can be directly taken by the terminal device, or the user can select a photo and upload it to the terminal device;

[0061] like Figure 3 As shown, the photo includes EXIF ​​information, i.e., the attribute information and shooting data of the photo; and allows obtaining location information when taking photos with a camera;

[0062] like Figure 4 As shown, the attribute information in the photo includes: lat: 39.35184°, lon: 116.45359°, height: 0 meters;

[0063] like Figure 5 As shown, it is a satellite image diagram, and the center point location information is extracted from the original data of the satellite image to obtain the longitude and latitude information, such as the longitude and latitude information string, for example, 39.5885° north latitude, 116.7600° east longitude, and 0 meters above sea level;

[0064] like Figure 6 As shown, it is a reverse location code analysis diagram, and the location code string is input, for example, No. 20, Yunpeng Road, Langfang Economic and Technological Development Zone; the input location code POI is subjected to reverse geographic location coding analysis to obtain the longitude and latitude information, which is lat: 39.58857°, lon: 116.76071°, height: 0 meters.

[0065] The attribute information is obtained by the terminal device parsing the information carrier; the attribute information includes: longitude and latitude information, time, shooting angle, length and width of the terminal device screen, initial angle information, record unique value, user unique value, photo storage location, photo name, and video format;

[0066] The intermediate server extracts the latitude and longitude information from the attribute information;

[0067] The intermediate server sends the extracted longitude and latitude information to the video server; the longitude and latitude information includes: longitude value lon, latitude value lat and elevation value;

[0068] A user-unique video server is started according to user information; the user information includes: user ID and user name.

[0069] The intermediate server sends the latitude and longitude information and other attribute information to the video server through real-time communication.

[0070] The video server is turned on, and the video server initializes and creates a terminal device simulator;

[0071] The video server sets the length and width of the terminal device simulator according to the length and width of the terminal device screen in other attribute information;

[0072] The video server determines the initial position and initial angle on the three-dimensional map according to the latitude and longitude information; here, the initial angle can be set to 30° when looking down. If an initial angle exists, it is set according to the actual initial angle. If no initial angle exists, it is set according to the default value of 30°.

[0073] Extract the latest tiles of all levels from the initial position;

[0074] Get the location point generated by the terminal device simulator when loading the latest tile for mapping;

[0075] The moment when the object point at the initial position is drawn is taken as the starting point of the change process, the transformation process is started, and the recording starts after the set time. Here, the delay setting time is 1 second to ensure the integrity of the picture.

[0076] The terminal device simulator starts recording the video according to the set recording process, and executes the end command when the last perspective change end event is executed to end the recording process, thereby obtaining a perspective change positioning video that matches the three-dimensional map with the location points and the texture; the perspective change positioning video is scaled from the latitude and longitude position animation to the global perspective to form a three-dimensional display effect.

[0077] The setting of the recording process includes: setting the transformation process time, the transformation center point position, the transformation camera angle of view, and the transformation height.

[0078] The intermediate server receives the perspective change positioning video;

[0079] Then the type of information carrier is determined through the intermediate server.

[0080] If the information carrier is a photo, the photo is combined with the perspective change positioning video to obtain the target video;

[0081] The merging of photos and perspective change positioning videos specifically includes:

[0082] Processing the photo by video transcoding or other methods to obtain a video clip;

[0083] The video clip is placed before the perspective transformation positioning video, and the gradient function is used to process the beginning node of the target video and the connection node between the video clip and the perspective transformation positioning video to obtain the target video and optimize the user viewing experience.

[0084] If the information carrier is not a photo, but an information carrier such as a latitude and longitude information string, a satellite image or a location code, then the video positioned by the perspective change is the target video;

[0085] When the information carrier is a satellite image, the satellite image is published through the intermediate server for layer service. After publishing the layer, the intermediate server returns information such as the layer name, layer service address, layer range, and layer workspace. The three-dimensional map in the terminal device simulator loads the layer service according to the returned information, and initially locates to the range according to the layer range. Mapping is performed according to the range, and the perspective is transformed with the mapping completion time as the time starting point to obtain the perspective transformation positioning video, which is the target video.

[0086] Here, the range of longitude values ​​is, for example, 116.6292770534202°-116.81515518016158°; the range of latitude values ​​is, for example, 39.52295175074187°-39.62669625059618°;

[0087] The intermediate server stores the target video in a database and extracts the video link generated by the database;

[0088] Finally, the intermediate server sends the video link to the terminal device. When the terminal device is a mobile phone or iPad, the user clicks on the video link from the terminal device, downloads the target video in the link to the local computer, and can also share the video link on other platforms.

[0089] Furthermore, the progress display of the target video specifically includes:

[0090] When the information carrier is not a photo, the generation progress of the perspective transformation positioning video is the generation progress of the target video; the terminal device divides the perspective transformation positioning video into multiple segments according to the set transformation process, and the ratio of each segment to the total transformation process is the progress value of each segment;

[0091] When the information carrier is a photo, the progress of merging the photo and the perspective change positioning video is the progress of generating the target video; the terminal device determines the time required to complete the merging of the photo and the perspective change positioning video according to the size of the photo and the size of the perspective change positioning video, and then obtains the current merging progress value according to the ratio of the actual merging time to the required merging time;

[0092] The terminal device dynamically displays a target video generation progress bar, and the progress bar displays the target video generation progress.

[0093] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
