Description
Technical field
The invention relates to kinds of 720 degree image processors around photography, is with the combination of two groups of wide-angle lens, formation ultra-wide angle and without the photographic image at dead angle.
Background technology
Generally be directed to camera, the maximum field image to 180 degree only can be provided, to reach the image photographic of 360 degree, panorama, then just must can provide the complete visual field of 360 degree by multi rack panoramic camera, but the deviation visual field had on visual angle and visual dead angle.And generally traditional 720 degree around photography, it is the mode coordinating rear system, the partial image that multi rack panoramic camera absorbs, namely less than the image of 360 degree, be connected for annular 360 degree, again connect push up the end become 720 degree around simulating image, tradition 720 degree when providing 720 degree of images, is able to the unspecified angle direct-vision image of 360 degree, periphery around photography, coordinates the image looked at straight with the unspecified angle at the angle of depression or the elevation angle.
Above-mentioned known 720 degree of photographies need to set up multi rack video camera at periphery, have lap mutually, so that through computer to lap montage, and obtain the full-view image of seamless gaps and omissions to absorb surrounding image.At erection top, top video camera, overlapping top image can be had mutually to absorb with surrounding image, to do montage through computer to lap, and obtains 720 degree of seamless full-view images around photography; Known 720 degree around photography picked-up 720 degree around multiple raw videos after, must carry out, around system process after image, then carrying out manual operations around image joining process; First joining process needs the closing line stipulating out adjacent two photos, to complete 720 degree around photography finished product.
As can be seen here, above-mentioned traditional approach still has many shortcomings, and is badly in need of being improved.
Summary of the invention
Namely object of the present invention is a kind of 720 degree of image processors around photography, be divided into image input one and image to input two by 2 groups of devices to form, it respectively comprises Region Segmentation unit, outside and interior zone signal mixed cell, signal contrast intensification unit, transformation curve averaging unit, and color signal compensating unit, wherein two groups of Region Segmentation unit, it is a zone signal that when image inputs, GTG signal dividing processing pluralized, to the grey menu of a plurality of subregion (i.e. zonule) be divided into be integrated with interior zone signal mixed cell by outside again, two groups of outside and interior zone signal mixed cells, connect with described Region Segmentation unit, described image input 1 and image input 2 outside and interior zone signal mixed cell be also interconnected, and carry out mixing and confluence analysis in this GTG input signal adding perimeter, two groups of signal contrast intensification unit, be connected to described outside and interior zone signal mixed cell after, and the signal after confluence analysis is carried out the distribution of intensity, and obtains profiles versus's value, then distribution intensity is redistributed produce new transfer equation, two groups of transformation curve averaging units, connect with described signal contrast intensification unit, process the transfer equation after the integration of described signal contrast intensification unit, and transfer equation is stored in this, and make average treatment with multiple picture gained transfer equation front, produce new average transfer equation, two groups of color signal compensating units, are after being connected to described transformation curve averaging unit, and add GTG input signal, are changed producing GTG output signal through above-mentioned transfer equation, finally mix color signal again and integrate, obtain GTG and colored output signal.
