Description
Technical field
The present invention relates to technical field of security, particularly relate to a kind of security device distribution design method based on Computerized three-dimensional scenario simulation technology.
Background technology
Existing monitoring system, owing to lacking the overall scenario information in monitoring region, is difficult to the monitor video of two dimension is carried out efficient association with actual three-dimensional environment, and the scattered monitor video of magnanimity not only " had been not able to watch over " but also " see and less understand ". Displaying is concentrated, it is impossible to large scene situation is carried out the overall situation and holds in real time and control, thus really effective means can not be provided for entirety association, integrated dispatch owing to lacking seamless fusion the to multi-mode many number of images information.
Each story board monitor video is visual angle, local only, for the region having multiple photographic head to cover, in order to obtain the camera shooting and video of optimal viewing angle, relies primarily on the hand picking wasted time and energy, it is possible to cause the delay of the deviation of analysis, mistake or even emergency response; Same problem exists in the historical events based on video data and searches in backtracking, as in order to a suspect is reversely traced, checking massive video data by hand if relying on, not only wasting time and energy, and a suspect's mass motion track in whole scene cannot be found out clearly. Strong technical support cannot be provided for the integrated management of accurately guidance, accurate prevention and control, precision strike.
Particularly in the safety-protection system in city, the problems referred to above are especially apparent, and cause that the video monitoring equipment installed puts into too much, and video monitoring effect is barely satisfactory.
Summary of the invention
The present invention provides a kind of security device distribution design method based on Computerized three-dimensional scenario simulation technology, decreases the equipment investment of camera head, improves city video monitoring effect.
The present invention is achieved through the following technical solutions:
Based on the security device distribution design method of Computerized three-dimensional scenario simulation technology, comprising:
Step 1, arranges the three-dimensional virtual scene of simulation monitored site, and according to camera head physical location in monitored site, the correspondence position at three-dimensional virtual scene adds virtual camera head;
Step 2, technical parameter according to camera head, photographic head for different model sets up three-dimensional data model, and described technical parameter includes: clear-vision distance, fuzzy sighting distance, illumination sighting distance, horizontal view angle, height visual angle, The Cloud Terrace horizontal rotation angle scope, The Cloud Terrace height rotation angle range;
Step 3, chooses matching characteristic point from the two-dimensional video image that described camera head obtains, and according to described matching characteristic point correspondence mappings point in described three-dimensional virtual scene, obtains exact position and the attitude of described virtual camera head according to matching algorithm;
Step 4, is incorporated in described three-dimensional virtual scene by the two-dimensional video image that described camera head obtains;
Step 5, step 1-4 is applied in the safety-protection system of three-dimensional city, the model of the camera head according to three-dimensional city safety-protection system and installation site, in conjunction with camera head visual range three-dimensional data model, set up the video monitoring visual range data model of urban global.
While setting up three-dimensional virtual scene, calculate each camera head dead angle, block, visual field overlapping cases, be together shown in three-dimensional city.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention, by the Digital Three-Dimensional model of placement and movable video monitoring equipment, the video monitoring range after simulator installation, provides three-dimensional simulation scene efficiently and effectively for design planning personnel. By this analog form, can more reasonably design the mount scheme of video monitoring equipment, reduce equipment investment, improve video monitoring effect. The scope of whole city's video monitoring is very clear, provides effective digital simulation foundation for realizing " all standing of emphasis public territory ".
