Abstract
The invention discloses a kind of GPS track playback methods, including following method: step 1): loading electronic map in vehicle driving record system；Step 2): driving recording video information is parsed；Step 3): video information is played.The invention reside in providing, a kind of label geographical location is accurate, and garage track is clear, and can play a kind of GPS track playback method of the garage track.
Description
Technical field
The present invention relates to a kind of image information processing method more particularly to a kind of GPS track playback methods.
Background technique
The map software of the prior art can only determine in real time the geographical location of user, but can not obtain user place
The pertinent image information in geographical location, if usage record instrument record image information can not obtain geographical location information in real time again,
It is even more impossible to learn the motion track of user, this has the law enforcement activities of strict demand to bring evidence format to investigation and evidence collection etc.
Inconvenience.
Chinese Patent Application No. are as follows: 201210182074.2, the applying date is: on 06 05th, 2012, publication date was: 2012
19 days 09 month year, patent name are as follows: the method for synchronizing determining motion profile with the video file comprising GPS information, the invention
By GPS module acquisition current location GPS data and video is written during acquiring image information with by recorder
H.264 in encoded tracks, then sync mark is out in map software in playing process by GPS audio video synchronization playout software
The mode of reason location information realizes motion profile when synchronizing the shooting of determining video file.The present invention has the advantages that with
This mode not only geographical location information of available user and relevant image information, it will be appreciated also that mark
The motion profile of user.
Above patent document discloses a kind of side that determining motion profile is synchronized with the video file comprising GPS information
Method, but the geographical location information error of this method mark is big, motion profile is indefinite, to user cause it is very big not
Just.
Summary of the invention
In view of this, accurate the invention reside in a kind of label geographical location is provided, garage track is clear, and can play
A kind of GPS track playback method of the garage track.
In order to achieve the object of the present invention, following technical scheme can be taken:
A kind of GPS track playback method, including following method:
Step 1): electronic map is loaded in vehicle driving record system；
Step 2): driving recording video information is parsed；
Step 3): video information is played.
The vehicle driving record system is vehicle-mounted traveling recorder.
It is described by driving recording video information carry out parsing include that the video location is found according to video file format, according to
The video location information deviated and analyzed the longitude and latitude for getting each GPS information and including, the date, speed, angle and
Acceleration etc..
The video file format is MP4 or is MOV.
The step 2) further includes that the GPS information is loaded into the video information, if the video information has GPS letter
Breath, then render the map track.
The step 2) further includes that the GPS information is loaded into the video information, if the video information is believed without the GPS
Breath, then prompt to fail.
It is the time according to video playing that the step 3), which plays video information, show the current GPS track time speed,
Angle, while drawing the line chart of the GPS track acceleration.
The beneficial effect of the technical scheme provided by the present invention is that:
1) the related geographical location on image information acquisition ground, can be obtained while handling the image information that user records
Information；
2), image information and geographical location information are with broadcasting is shielded, convenient for inquiry, comparison；
3) recording track of image information can be marked, on the electronic map, convenient for investigating and collecting evidence.
Detailed description of the invention
Fig. 1 is GPS track of embodiment of the present invention playback method side flow chart of steps.
Specific embodiment
With reference to the accompanying drawing and the embodiment of the present invention is described in further detail invention.
Embodiment 1
Referring to Fig. 1, a kind of GPS track playback method includes the following steps:
Step 1) opens the APPS1 in vehicle driving record system；
Step 2): electronic map S2 is loaded in vehicle driving record system；
Step 3): driving recording video information is subjected to parsing S3；
Step 4): video information S4 is played；
Step 5): terminate S5；
In the present embodiment, the vehicle driving record system is vehicle-mounted traveling recorder.
It is described by driving recording video information carry out parsing include that the video location is found according to video file format, according to
The video location information deviated and analyzed the longitude and latitude for getting each GPS information and including, the date, speed, angle and
Acceleration etc..
Firstly, the video information that the automobile data recorder is recorded saves, the file format which saves be MP4 or
Person MOV, the Video Information files format find the specific location of freegps this field in video；
Because the GPS information per second got when GPS information is written, can be written to each different position by the end DVR,
Such as 180 seconds video, 180 GPS informations are had, this 180 information can be respectively written into 180 positions, and 180
A specific position has been saved to using freegps as in one section of memory of start information；
Getting the content in this section of memory is the position where specific GPS information is real, then further according to these
Position is deviated and is analyzed the longitude and latitude for getting each GPS information and including, date, speed, angle and acceleration etc..
In the present embodiment, the electronic map is Baidu map either Google Maps；
In this implementation, the video can be MOV format either MP4 format, and other formats, which have, plays frame prompt；
The video information is preferably the video that the DVR that Shenzhen Ah Da researches and develops depending on new and high technology Co., Ltd is recorded,
The video information has write-in GPS information, and map making path effect is more preferable.
In the present embodiment, the step 2) further includes that the GPS information is loaded into the video information, if the video information
There is the GPS information, then renders map track S31.
The step 2) further includes that the GPS information is loaded into the video information, if the video information is believed without the GPS
Breath, then prompt unsuccessfully S32.
In the present embodiment, it is the time according to video playing that the step 3), which plays video information, shows current GPS track
Speed, the angle of time, while drawing the line chart S41 of the GPS track acceleration.
In the present embodiment, video has been parsed, video plays at once, meanwhile, the entire GPS route rail of the drawing electronic map
Mark draws the GPS track acceleration line chart then according to corresponding position coordinates on the time moving map of broadcasting, display
Current speed and angle.
It is more accurate that the invention shows geographical locations, and display GPS motion profile is definitely, more convenient to use, exchanges
Whole evidence obtaining is more convenient.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention.
