Abstract
The invention belongs to the technical field of photoelectric product application, and particularly relates to a panoramic mosaic device and method based on the space coordinates of an image. The panoramic mosaic device based on the space coordinates of the image comprises a signal generation board, a camera, an image acquisition board, an angular sensor, mosaic software and a display screen. Mosaic is carried out according to the actual space coordinates corresponding to the image without overlapping of adjacent image frames and is not influenced by the amount of background information; only simple data reading is carried out without image processing, and real-time performance is good; all involved hardware is original software of a photoelectric search system, and it is only needed to lead external synchronization signals and angular sensor output signals to the image acquisition board. When two adjacent image frames overlap, the rear image frame can cover the overlapping part of the front image frame after mosaic; when the two adjacent image frames do not overlap or have a gap, the image frames still correspond to the real angular positions after mosaic, and the situation that because deviation exists between the actual field of view of the camera and a design value, accumulated errors are caused will not occur.

Traditional Panoramic Mosaicing technology is as document " actualizing technology of Panoramic Mosaicing " (Xu Haiyun etc., Beijing University of Technology's journal, Vol.30,2004) described in a literary composition, be carry out registration to realize based on to the lap of adjacent two two field pictures, and require overlapping part comparatively large (" actualizing technology of Panoramic Mosaicing " a literary composition suggestion be about 50%).And in photoelectric search system, for ensureing data transfer rate, the lap between two two field pictures is little or do not have; And the background of image is generally sky, even if image has overlap also can be difficult to registration because background is single; In addition, the photoelectric search system requirements search cycle short (usually a circle per second), thus very large at image data amount, traditional pattern splicing method needs to carry out the computing such as rim detection, image registration, and real-time is difficult to ensure.
Therefore, need a kind of Panoramic Mosaicing method based on image space coordinate of development badly, thus solve that photoelectric search system image background is single, interframe is less overlapping or real time panoramic picture mosaic problem under zero lap condition.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of Panoramic Mosaicing method based on image space coordinate, with the real time panoramic picture mosaic problem solving that photoelectric search system image background is single, interframe is less overlapping or under zero lap condition.
In order to realize this purpose, the technical scheme that the present invention takes is:
Based on a Panoramic Mosaicing device for image space coordinate, comprise signal generation plate, video camera, image acquisition board, angular transducer, picture mosaic software and display screen;
Wherein, signal generation plate produce be used for toggling camera external synchronization signal, external synchronization signal is delivered to video camera and image acquisition board;
Video camera is external trigger pattern, the external synchronization signal that Received signal strength generation plate produces, and starts exposure after this signal of reception; Under the effect of external synchronization signal, realize camera exposure and gather the synchronous of space coordinates with image acquisition board;
Angular transducer is for servo-controlled Angle Position feedback element, the space coordinates that the current frame image that measurement of inductance video camera obtains is corresponding;
The space coordinates that image acquisition board reading angular transducer exports in real time, and after the complete current frame image of camera exposure, gather this two field picture and the space coordinates read before is write in view data;
The view data comprising space coordinates that picture mosaic software reading images collection plate exports, puts image by the space coordinates in view data the coordinate position place of correspondence;
After processing into Panoramic Mosaicing frame by frame, by display screen, Panoramic Mosaicing is shown.
Further, a kind of Panoramic Mosaicing device based on image space coordinate as above, the external synchronization signal that signal generation plate produces is square wave, and square wave frequency is consistent with the frame frequency of video camera, and amplitude sets according to the input requirements of video camera.
Further, a kind of Panoramic Mosaicing device based on image space coordinate as above, angular transducer adopts the one in following two kinds of devices: photoelectric code disk, resolver.
Utilize the Panoramic Mosaicing method based on image space coordinate of a kind of Panoramic Mosaicing device based on image space coordinate as above, comprise the following steps:
(1) picture mosaic software building coordinate system, puts view data according to space coordinates for the space coordinates in correspondence image data and in subsequent step in the coordinate system built;
(2) signal generation plate produces external synchronization signal and delivers to video camera and image acquisition board simultaneously;
(3) video camera starts exposure after the external synchronization signal receiving the generation of signal generation plate;
(4) space coordinates that the current frame image that obtains of angular transducer measurement of inductance video camera is corresponding;
(5) space coordinates that exports in real time of image acquisition board reading angular transducer;
(6) after the complete current frame image of camera exposure, image acquisition board gathers this two field picture and spatial value corresponding for the current frame image read before is write in view data;
(7) view data comprising space coordinates of picture mosaic software reading images collection plate output, puts image by the space coordinates in view data the coordinate position place of correspondence;
(8) repeat step (2)-(7), until process into Panoramic Mosaicing frame by frame, by display screen, Panoramic Mosaicing is shown.
Further, a kind of Panoramic Mosaicing method based on image space coordinate as above, in step (6), after the complete current frame image of camera exposure, image acquisition board gathers this two field picture and spatial value corresponding for the current frame image read before is write the frame head of view data.
By the enforcement of technical solution of the present invention, picture mosaic can be carried out by the real space coordinate corresponding according to image, overlapping without the need to consecutive frame image, do not affect by image background amount of information; Just simple digital independent, do not carry out image procossing, real-time is good; Involved hardware is the original hardware of photoelectric search system, and only external synchronization signal and angular transducer output signal need be guided to image acquisition board, hardware modifications is very little.When adjacent two two field pictures have overlap, a rear two field picture can cover the part of former frame overlap after picture mosaic; When adjacent two two field pictures do not have overlap or have gap, each two field picture after picture mosaic is its real Angle Position corresponding still, can not have deviation because of the practical field of view of video camera and design load and produce accumulated error.
