The invention provides a video playback method and system based on a map track. The method comprises the following steps of recording and storing a travelling video; collecting information points of a vehicle according to the set frequency and processing the information points, wherein the information points include time, GPS (Global Positioning System) information, speed and direction of the current vehicle; forming a travelling track through the GPS information and displaying on an electronic map; selecting a position on the track as an origin for video playback, correspondingly obtaining a moment of the vehicle at the position through the position and starting playing the travelling video from the moment. According to the video playback method and system, the efficiency for a user to look back the travelling video can be improved to be convenient for the user, the user experience is better, and furthermore, the memory space of the playback system is reduced and the playback is correspondingly faster.
Description
technical field [0001] The invention is applicable to the technical field of the Internet of Vehicles, and in particular relates to a video playback method and system based on map tracks. Background technique [0002] In the existing driving recorder video playback technology, the processing methods for realizing watching the video in the driving recorder include: one is to pull out the SD card in the driving recorder and connect it to a PC for viewing. Another method is to connect the driving recorder through the mobile phone and play the video at a specified time point. Regardless of the solution, the corresponding video can only be played according to the playback time point, and video playback can only be performed from the time dimension. This requires the user to have a very clear memory of the time when the accident occurred when looking for the accident point, or browse the video from beginning to end, so that the information that the user needs to watch cannot be q...
