Coordinate of the pixel in polar coordinate system.
Step S15, the pixel value of the pixel in the first image positioned at the second coordinate is defined as first in the 3rd image
The pixel value of pixel.
, can be from first after second coordinate of first pixel in polar coordinate system is obtained in above-mentioned steps S15
The pixel positioned at second coordinate is determined in the corresponding polar coordinate system of image, and regard the pixel value of the pixel as the 3rd figure
The pixel value of the first pixel as in.
It should be noted that being performed both by above-mentioned steps S11 to step S15 to each pixel in the 3rd image, just may be used
To realize the first image spread obtained by the first camera photographic subjects scene in the way of reversely searching pixel into
Three images.
Similarly, obtaining the 4th image to the deployment algorithm performed by the second image can be described as：To in the second image
Pixel carries out polar coordinate system and is converted to the 4th image to rectangular coordinate system, specifically may comprise steps of S12 to step
Rapid S16：
Step S12, according to the length and width of the image of width calculation the 4th of the second image, wherein, wrapped in the 4th image
The pixel of the second quantity is included, the second quantity is the product of the length and width of the 4th image.
, can be with after the second image that second camera photographic subjects scene is obtained is got in above-mentioned steps S12
According to the width of the second image, namely the diameter of circular picture shown in Fig. 7 b calculates the image after being deployed, namely the 4th figure
The length and width of picture.It should be noted that the pixel in the 4th image can be determined by the length and width of the 4th image
Quantity, namely the 4th image includes the pixel of the second quantity, wherein, the second quantity is the length and width of the 4th image
Product.Each pixel in 4th image can use the coordinate representation in rectangular coordinate system.
Step S14, by the 3rd Coordinate Conversion of the second pixel in the 4th image into 4-coordinate, wherein, the second quantity
Pixel include the second pixel, the 3rd coordinate is coordinate of second pixel in rectangular coordinate system, and 4-coordinate is the
Coordinate of two pixels in polar coordinate system.
In above-mentioned steps S14, the 4th image includes the pixel of the second quantity, wherein, the second pixel can be

As a kind of optional embodiment, lens parameters, resolution sizes that the embodiment can be in known capture apparatus
And rectangular co-ordinate is tried to achieve in calculating in advance in the case of field range and the corresponding relation value of polar coordinates pixel is put into result
In reservations database or internal memory, in order to by the first Coordinate Conversion of the first pixel in the 3rd image into the second coordinate and
Table look-at is operated when by the 3rd Coordinate Conversion of the second pixel in the 4th image into 4-coordinate, and table look-up behaviour
It is only O (1) as time complexity, can so realizes the effect for reducing data amount of calculation.
Specifically, the first Coordinate Conversion of the first pixel in the 3rd image may comprise steps of into the second coordinate
S131 to step S133：
Step S131, it is corresponding with coordinate transformation relation value pair according to the camera properties parameter stored in reservations database
Relation determines the corresponding first coordinate transformation relation value pair of the first camera properties parameter, wherein, the first coordinate transformation relation value
To for indicating that the first coordinate of the first pixel in the 3rd image is corresponding with the second coordinate.
In above-mentioned steps S131, the camera properties parameter that can be stored with precalculated in reservations database is with sitting
Mark transformational relation value pair corresponding relation, herein it should be noted that different camera properties parameters can correspond to it is different
Coordinate transformation relation value pair, wherein, coordinate transformation relation value is to can serve to indicate that between rectangular co-ordinate and polar coordinates pixel
The corresponding relation changed.It should also be noted that, camera properties parameter can include at least one of：Camera
Resolution ratio of image etc. captured by angular field of view, camera.
It should also be noted that, the first camera properties parameter can be included in the corresponding relation stored in reservations database
Corresponding first coordinate transformation relation value pair, can not also include corresponding first Coordinate Conversion of the first camera properties parameter and close
Set occurrence pair, wherein, the first coordinate transformation relation value to can serve to indicate that in the 3rd image the first coordinate of the first pixel with
Second coordinate is corresponding.
As a kind of optional embodiment, in order to directly quickly determine the using the corresponding relation in reservations database
Corresponding second coordinate of first coordinate of the first pixel in three images, the embodiment can be in step S131 according to corresponding relation
Determine the corresponding first coordinate transformation relation value of the first camera properties parameter to, first judging whether deposited in reservations database before
With the first camera properties parameter identical camera properties parameter.Exist and the first camera properties in reservations database
In the case of parameter identical camera properties parameter, the embodiment can determine that the first camera properties are joined according to corresponding relation
The corresponding first coordinate transformation relation value pair of number；It is not present and is taken the photograph with the first camera properties parameter identical in reservations database
In the case of as head property parameters, the embodiment needs to adjust the first camera properties parameter first so that being deposited in reservations database
With the first camera properties parameter identical camera properties parameter after adjustment, then further according to corresponding relation determine adjust
The corresponding first coordinate transformation relation value pair of the first camera properties parameter afterwards.It can so guarantee to utilize tentation data
The corresponding relation stored in storehouse quickly and easily finds the corresponding first coordinate transformation relation value of the first camera properties parameter
It is right, the efficiency of Coordinate Conversion is drastically increased, while decreasing the amount of calculation of Coordinate Conversion.
Step S133, the first coordinate pair of the first pixel in the 3rd image is determined according to the first coordinate transformation relation value pair
The second coordinate answered.
