Embodiment Construction
[0080] In this example, if figure 1 As shown, a kind of 3D scene reconstruction method based on video with GPS information is carried out according to the following steps:
[0081] Step 1. Build a FOV model set based on GPS information and remove redundant frame data:
[0082] Step 1.1, utilize the mobile device with camera and GPS function to obtain the video data of the M frame target scene that contains GPS information, GPS information comprises: the longitude and latitude vector of camera, the angle of elevation of camera and the angle of view of camera; Except utilizing camera and GPS Functional mobile devices can obtain video data, and video data can also be obtained through video sharing platforms with GPS information, such as GeoVid video sharing platform (http: / / api.geovid.org) to obtain video data; M frames of video data are constructed from M frames FOV (Field-Of-View, FOV for short) model triplet, so as to build a FOV model set based on GPS information, denoted as...
