Moving video track and video playback synchronization displaying method in electronic map

Abstract

The invention discloses a moving video track and video playback synchronization displaying method in an electronic map. When a video content is photographed, GPS moving track information including coordinate and elevation data and the posture data of an IMU (inertial measurement unit) which is rigidly and fixedly connected with an aerial photo camera at a certain sampling frequency are acquired. Solving GPS data and IMU (inertial measurement unit) data are jointed to determine the field position coordinates of an image center. The index relationship between a position sequence and a video frame sequence is established, and the index relationship is used to determine the mapping between an edited video and the position information to acquire a position marker sequence. According to the position marker sequence, the marker video of a video scene moving track is recorded and displayed, and the marker video is embedded into a playback video for synchronization playback. When the video content is played, the moving video track is displayed on the electronic map.

Description

Technical field [0001] The invention relates to a track display method, in particular to a method for synchronously displaying a moving video track on an electronic map and video playback. Background technique [0002] At present, there are more and more video shooting applications based on mobile media, such as satellite shooting, drone aerial photography, and driving record. Among them, drone aerial photography and driving record are used in an increasingly wide range. This kind of shooting method, especially the video results of drone aerial photography, usually rely on human eyes to identify specific locations. This is because the video results obtained by drone aerial photography have the characteristics of multiple shooting points, large span, wide coverage, rapid changes in shooting scenes and moving paths, and a long distance between the lens and the ground. GPS positioning can only solve the positioning of the carrier and lens. Therefore, video results shot by mobile ca...
