Description
Technical field
The invention belongs to video security protection fields, are related to a kind of side for tracking and shooting with video-corder and visualize backtracking indoor occupant behavior
Method.
Background technique
Video is the extremely huge information carrier of information content, by image, sound and video recording time, objective can be remembered
Record visual, the sound activity that a certain period occurs in some scene.This characteristic of video is widely used in video
Personal entertainment, security protection, investigation and evidence collection, information reception and registration etc. field.And in the concrete application of safety monitoring, due to video recording
Equipment is usually that fixed point is installed, fixed angle is shot with video-corder, therefore video is typically only capable to the event in record certain area.To cover
It is region-wide, it is necessary to which that when disposing camera, uniform fold is to all areas.Therefore during concrete application, some interior fixed
The environment same time can generate multi-path video stream, every to be responsible for recording the event of a certain subregion all the way.
In specific application process, Indoor Video is commonly used for behavior auditing and the backtracking of personnel's trend of indoor occupant.By
There may be multichannel in video monitoring, therefore the behavior of some personnel section time indoors and trace is recalled, tradition
Method is checked one by one to all videos, the artificial trace for finding target person in video, low efficiency, and difficulty is big.If
It needs to carry out whole backtracking to the activity of certain personnel, knowing for sure, where someone has done what, what activity trajectory is
Sample, just very labor intensive and time.
The mode manually searched is removed, newest application mode is the mode identification method based on artificial intelligence, to all
The image of designated person is identified and is detected in monitor video, so that it is determined that the region of target person appearance and period, knot
The riding position of camera is closed, is realized to behavior in target person room and the backtracking of track.But this method relies on artificial intelligence skill
Art, it is higher to hardware device performance requirement, and due to needing to carry out recognition of face, it is more demanding to camera, to camera shooting
Head is placed angle and is also required, and having disposed place in some cameras not can be used directly and dispose.
Path backtracking aspect, to personnel track in space usually using dedicated indoor positioning scheme, though precision is high, at
This is also very high.Personnel positions identification for part low cost, is also only realized by the way that gate inhibition is this by type judgment method,
This mode can only determine whether personnel enter a region, for example enter library, enter the spaces such as meeting room, but nothing
The position of zonule where method further determines personnel.
In conclusion in the prior art, to indoor occupant behavior auditing and retrogressive method Shortcomings and problem:
1, artificial backtracking, manpower and time cost are very high, and practicability is poor.
2, the time that personnel occur in video is retrieved by modes such as recognition of face or Gait Recognitions and realize backtracking, to setting
Standby performance requirement is higher, also higher to equipment placement angle requirement, and application cost is relatively high.
3, the usually not preferable solution of key position and path to personnel indoors, can still rely on camera
Location information auxiliary judgment.
Summary of the invention
Present invention problem in view of the deficiencies of the prior art proposes a kind of tracking and shoots with video-corder and visualize and recalls indoor occupant row
For method, the record of personnel's approximate location indoors is realized based on RFID device, by the way that camera angle and position is rationally arranged
It sets, guarantees that the camera for covering each region can cover anchor point associated by RFID device simultaneously.Personnel pass through wearing
