Abstract
The invention relates to a video monitoring site record restoring method and a device. The video monitoring site record restoring method comprises the steps of: installing a three-dimensional cradle head camera on the original camera position, shooting video record of a monitoring site, displaying one picture in the site video record for shooting of the original camera on a display device, adjusting the size and the transparency of the picture, adjusting the position statuses and the focusing points of horizontal deflection, vertical pitching and axial rotation of the three-dimensional cradle head camera, leading a foreground image and a background image to be coincided accurately, obtaining the three-dimensional cradle head camera in the position status of the original camera, using the three-dimensional cradle head camera to shoot the video record of a criminal suspect which repeats the activity of a target person on the monitoring site, and obtaining the video record restoring the original site. In the invention, the three-dimensional cradle head camera not only has a horizontal rotation driving device and a vertical rotation driving device of a two-dimensional cradle head camera, but also has an axial rotation driving device, the picture in the site video record is accurately coincided with the picture in the original site video record, and the restored video record of the original site is obtained.
Description
Technical field
The present invention relates to a kind of disposal route and device of in criminal investigation work, dynamically being recorded a video in the video monitoring scene, on-the-spot restoration methods and the device of dynamically recording a video of particularly a kind of video monitoring.
Background technology
In management, adopt video monitoring system more and more to key sector or important place.Video monitoring system can obtain the video record of target people activity in the paroxysmal abnormality incident at the scene in real time.The video record of target people's activity is to find target people important evidence.For the video record with target people activity can find the target people in the suspect, a kind of person recognition method based on behavioral characteristics is disclosed among the Chinese patent literature CN 01901337A, based on the person recognition method of behavioral characteristics be according to the monumented point on the moving human body in the video record in the horizontal direction, vertical direction and the three-dimensional relationship of time, the treated three-dimensional curve that obtains showing the dynamic personal feature of people.With the same degree that compares suspect and the dynamic personal feature three-dimensional curve of target people, judge whether target people and suspect are same people.The individuality of the dynamic personal feature three-dimensional curve reflection of above-mentioned people human body behavioral characteristics is strong, and the distinctiveness height is easy to use when making individual identification with this behavioral characteristics, has advantages of high practicability.
With above-mentioned person recognition method based on behavioral characteristics the time, except the movable at the scene video record of the target people that former video camera picked-up will be arranged, need to produce the suspect repeats target people activity at the scene of target people activity the movable at the scene video record of suspect, when making the movable at the scene video record of suspect, the location status that allows video camera be in former video camera is necessary condition, and the location status of video camera is meant the horizontal deflection of video camera, vertically faces upward and bow and the axial location status of rotation.The configuration state different on-the-spot dynamic video image that video camera absorbed in position for video camera is based on insufficient grounds on relatively.
If the location status of former video camera is constant, can absorb the movable at the scene video record of suspect at an easy rate with former video camera.If the location status of former video camera changes, or former video camera has not existed, then need to determine in the settlement of former video camera earlier the location status of former video camera, use the movable at the scene video record of suspect of the video camera picked-up of determining the good position state again, could be with above-mentioned person recognition method based on behavioral characteristics, the suspect compared at the video image of former site activity with the target people at the dynamic video image at former scene carry out individual identification.
In order to determine the location status of former video camera, a pictures and the live video image that absorbs with monopod video camera overlap the contrast that coincides in the computing machine of contrast program having video image and picture in the live video image of available former video camera picked-up, when contrast, regulate the location status of monopod video camera, allow in the video image that live video image and the former video camera of monopod video camera picked-up absorb should the scene a pictures coincide, can think that then this monopod video camera is the location status at former video camera.
In the prior art, monopod video camera is the two-dimensional pan-tilt video camera, the two-dimensional pan-tilt video camera can only and be faced upward the two dimension of bowing from level and regulate video camera, actually, also has position difference between the two-dimensional pan-tilt video camera of former video camera and above-mentioned definite former position for video camera configuration state around the rotation of camera lens axis, the two-dimensional pan-tilt video camera do not have can also actuated camera camera lens around the axial drive means of its axis rotation, so can not allow the live video image of monopod video camera picked-up overlap accurately with a pictures in the live video image that former video camera absorbs.Location status at former video camera changes, or there is not the video record at the former scene of very difficult picked-up recovery in former video camera.
Summary of the invention
The objective of the invention is to propose a kind of location status of monitoring on-the-spot former video camera and change, or when monitoring on-the-spot former video camera and not existed, can absorb the video monitoring live video restoration methods and the device that recover former live video video recording in order to overcome above-mentioned deficiency.
