The high speed random targets video recording apparatus that a kind of circulation and order automatically switch, including high-speed video acquisition camera, entirely
Orientation camera lens, sonic transducer, System Computer, comprehensive camera lens 1 is fish eye lens, is arranged in high-speed video acquisition camera,
Component computer is connected with high-speed video acquisition camera and is its power supply, the video sequence that high-speed video acquisition camera collects
Biographies logistics computer stores, and sonic transducer and component computer are connected to it provides triggering signal to realize storage
Circulation and order automatically switch；
Described circulation and order automatically switch and specifically comprise the steps of
(1) driftlessness storage
When without high-speed target, the image sequence taken by high-speed video acquisition camera is stored in sequence in component computer
The race way deposited；After race way storage is full, the image of a new frame is stacked is stored in race way, simultaneously remaining in race way
The two field picture being stored at first pop and be dropped；
(2) target is had to store
When high-speed target occurs, sonic transducer collects acoustical signal, and is sent to component computer, triggers storage side simultaneously
The switching of formula, image sequence is stored in sequence in the memory area of component computer internal memory；After memory area storage is full, all
Video sequence in internal memory saves as a video file and is stored in the hard disk of component computer.
The invention has the beneficial effects as follows: high speed panoramic video acquisition camera can record supersonic target；By comprehensive camera lens
The video sequence visual angle gathered reaches 180 degree, and visual range is without dead angle；The storage mode handoff functionality triggered by sonic transducer,
The video sequence that can select effective target stores, and saves hard drive space.
Accompanying drawing explanation
Fig. 1 is a kind of circulation of the present invention and the high speed random targets video recording apparatus schematic diagram of order automatic switchover.
Fig. 2 is memory storage step explanation during driftlessness in the present invention.
Memory storage step explanation when Fig. 3 is to have high-speed target in the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described further.
The invention discloses a kind of circulation and the high speed random targets video recording apparatus of order automatic switchover, adopt including high-speed video
The parts such as collection video camera, comprehensive camera lens, sonic transducer, component computer.Use machine vision and the scheme of sounds trigger,
High-speed target is shot by application high-speed video acquisition camera by comprehensive camera lens, and the video sequence collected is by computer
Store.The internal memory of computer is divided into race way and recording areas two parts, and when driftlessness, the video sequence collected is following
Ring region circulation storage, when there being high-speed target to occur, the movement sound of high-speed object triggers sonic transducer, and video sequence storage is suitable
Sequence switches to storage to the recording areas of internal memory.When full memory is filled with, full memory content is stored as the video in a cycle
File, is stored in hard disk.The invention has the beneficial effects as follows: high speed panoramic video acquisition camera can record supersonic target；Logical
Crossing the video sequence visual angle that comprehensive camera lens gathered and reach 180 degree, visual range is without dead angle；The storage triggered by sonic transducer
Mode handoff functionality, can select the video sequence of effective target to store, and saves hard drive space.
The present invention realizes goal of the invention and the technical scheme is that employing machine vision and the method for image procossing, application regard at a high speed
Frequently high-speed target is shot by acquisition camera by comprehensive camera lens, and the video sequence collected is stored by computer.
The internal memory of computer is divided into race way and recording areas two parts, and when driftlessness, the video sequence collected circulates in race way to be deposited
Storage, when there being high-speed target to occur, the movement sound of high-speed object triggers sonic transducer, and video sequence storage order switches to deposits
Storage is to the recording areas of internal memory.When full memory is filled with, full memory content is stored as the video file in a cycle, is stored in
Hard disk.
The high speed random targets video recording apparatus that a kind of circulation and order automatically switch, the comprehensive camera lens of flake
1 is installed in high-speed video acquisition camera 2, and camera lens viewing angles-both vertical is to photographs sky, for catching the guided missile of high-speed motion,
The objects such as aircraft.High-speed video acquisition camera 2 is connected with component computer 3, and component computer is its power supply, and video camera is adopted
Collect to video information transmission store to component computer.Concrete storage mode is according to there being driftlessness, by sonic transducer 4
Penetrate to touch and signal to component computer 3 and carry out the switching of storage mode.Concretely comprise the following steps:
(1), when occurring without high-speed target, high-speed camera gathers video information transmission to system-computed by the comprehensive camera lens of flake
Machine, is circulated caching in the race way of component computer internal memory, and as shown in Figure 2, circle principle is followed in race way storage,
That is, after race way storage is full, a newly entering two field picture, the frame being stored at first in race way can be deleted, and storage order is successively
Along shift-in row circular buffer.
(2) when having high-speed target to occur, due to guided missile, the target speed such as supersonic plane is fast, by the target of sounds trigger
Identifying, stickiness when having, when sound transducer receives acoustical signal, has there is certain time in target, and this allows for sound
Sound sensor receives sound and touches the some frames before this time is also the useful frame having target.As shown in Figure 3, high speed mesh
Mark triggers sound transducer, triggers signal and sends component computer to, and storage mode changes, and newly enters frame and is stored in the memory block of internal memory,
Until internal memory is filled with, in internal memory, all the elements are stored as a video sequence and are stored in component computer hard disk.Memory cycle
After end, empty whole cachings of internal memory, start the circulation storage in a new cycle.
