Specifically, metadata in the ZJM files include navigation routes, and the ZJM files corresponding to the initial navigation configuration operation can be screened out from a plurality of pre-stored ZJM files through matching operation of the navigation routes, that is, a target video is determined from a video library.
It should be understood that the video library in embodiments of the present disclosure may contain one or more video amounts. If the video corresponding to the simulated vehicle cannot be screened based on the initial configuration operation of the simulated vehicle, the initial configuration operation can be prompted to be conducted again, such as text prompting or voice prompting on a map, so that the configuration of longitude, latitude and/or direction angle can be conducted again.
S84, determining a target video frame corresponding to the initial longitude and latitude of the simulated vehicle from the target video.
In the process of prerecording the target video, track data corresponding to each video frame are collected at the same time, and the track data at least comprises longitude and latitude corresponding to the video frame. Thus, a target video frame may be determined from the target video based on the initial longitude and latitude of the simulated vehicle. The target video frame is one image frame in the target video frames.
Specifically, the initial longitude and latitude of the simulated vehicle can be matched with the longitude and latitude corresponding to each video frame in the target video, and the video frame with the highest matching degree is determined from the target video to be used as the target video frame.
It should be appreciated that the acquisition of video frames has a time interval and that the initial longitude and latitude of the configured simulated vehicle does not necessarily coincide exactly with the longitude and latitude at the time of video frame acquisition, and thus, embodiments of the present disclosure require the computation of a degree of matching, i.e., a degree of positional similarity. And selecting a video frame with the position closest to the initial longitude and latitude from the target video as a target video frame.
S86, controlling the target video to start playing from the target video frame, and controlling the playing progress of the target video in response to the control operation aiming at the simulated vehicle.
After the target video frame is determined, the target video may be played starting from the target video frame. At this time, the picture of the display end is switched from the map to the target video frame.
In an exemplary embodiment of the present disclosure, the playing of the target video is not dependent on the time of the video itself, but is based on the travel control of the simulated vehicle. That is, the playback progress of the target video is controlled based on the control operation for the simulated vehicle.
The play progress of embodiments of the present disclosure may be generally characterized in terms of vehicle speed. Specifically, the speed of the simulated vehicle may be determined according to the control operation of the simulated vehicle, and the playing speed of the target video may be determined according to the speed of the simulated vehicle.
It should be noted that the control of the video playback progress of the present disclosure is real-time control, that is, if the speeds of the simulated vehicles are different at two times, the real-time video playback speeds are different for the two times.
The geographic location of the simulated vehicle may be provided by a map engine and the travel trajectory of the simulated vehicle may be determined by speed and direction. Under the condition that the longitude and latitude, the current speed and the direction of the current position are determined, the position of the simulated vehicle after any time period t can be calculated. If the speed (unit m/s) of the simulated vehicle is denoted as speed, the direction angle (the angle with the north direction is denoted as radian) is denoted as head, the driving distance is denoted as distance, the current latitude is denoted as lat, the current longitude is denoted as lon, the latitude after the time period t is denoted as new_lat, and the longitude after the time period t is denoted as new_lon, the calculation formula is as follows:
distance＝speed*t
new_lat＝lat+(distance*cos(heading)/DISTANCE_METER_PER_DEGREE new_lon＝lat+(distance*sin(heading)/DISTANCE_METER_PER_DEGREE
wherein, distance_meter_per_deglee may be set to a fixed value, which is a DISTANCE between latitudes differing by one DEGREE in the latitudinal direction, and may be taken as approximately 111319.488 METERs.
In addition, in the process of playing the target video, HUD data can be acquired and sent to the HUD rack, so that HUD display can be performed in the process of playing the target video. As indicated above, the HUD display content includes AR content and/or non-AR content, specifically including one or more of a route line, POI identification, vehicle speed, road speed limit, road name, navigation remaining distance, curve type, curve remaining distance.
Fig. 10 schematically shows an effect diagram of video playback in combination with HUD display. Referring to fig. 10, the display end may display information such as a track, a current speed, a curve type, a curve remaining distance, a POI (such as XX mall), and the like while displaying the video frame.
In addition, in the process of playing the target video, if the simulated vehicle deviates from the route corresponding to the target video, the current longitude and latitude, namely the longitude and latitude of the deviated position, is determined. Subsequently, the above-described process of selecting videos from the video library and selecting video frames from the videos is re-performed. Specifically, under the condition that the next video is determined from a pre-recorded video library in combination with the current longitude and latitude, the next video is controlled to start playing from a video frame corresponding to the current longitude and latitude, and the playing progress of the next frame is controlled in response to the control operation for the simulated vehicle.

In step S1112, the electronic device traverses the routes in all ZJM metadata, for example, selecting the first ZJM file containing the simulated vehicle' S current location.
In step S1114, the electronic device loads track data of the ZJM file.
In step S1116, the electronic device acquires the position coordinates of the simulated vehicle, that is, acquires the longitude and latitude of the simulated vehicle.
In step S1118, the electronic apparatus selects the frame number matching the position coordinates in step S1116 from the track data in step S1114.
In step S1120, the electronic device decodes the video frame and renders it.
In step S1122, the electronic device determines whether the video is played. If the playing is finished, ending the flow; if not, step S1124 is performed.
In step S1124, the electronic apparatus determines whether the ZJM route determined in step S1110 or step S1112 is currently deviated. If so, returning to step S1106; if not, return to step S1116.
