One, uneven, the picture image quality close apart from fish eye lens central area is good, the picture image quality remote apart from fish eye lens central area
Difference.For the picture of sky and the image on ground because being that the fish eye lens of camera surrounding is spliced jointly, effect is very poor.And
And in the horizontal direction, more camera lens pictures overlap covering waste pixel repeatedly, are promoted to image quality little.
In addition, as shown in figure 14, CMOS (the Complementary Metal Oxide of panorama camera
Semiconductor, i.e. complementary metal oxide semiconductor) chip is rectangle, and fish-eye imaging is round as circle.
In order not to lose the picture of camera lens, panorama picture of fisheye lens picture circle is often inscribed on the inside of cmos imaging rectangular area, this just exists
CMOS chip surrounding forms the dark angle of black, and practical cmos pixel utilization rate is less than 70%.Moreover, fish eye lens edge is abnormal
Become larger, picture distortion distortion, it is easier to seam, the especially Liang Jichu in flake panorama camera are formed, several splicing lines converge,
Seam is apparent.
As shown in Figure 15-Figure 16, the design of CCD camera assembly 1 image quality of the embodiment of the present invention is very uniform, and entire picture is all
The CCD camera assembly 1 in the relatively good region of image quality, the embodiment of the present invention replaces fish eye lens using wide-angle lens.Such as Fig. 9, Figure 11
And shown in Figure 13, wide-angle lens distorts to have obtained good control, and in splicing, especially seam obtains at the two poles of the earth of camera
Control well.
As shown in Fig. 1-Fig. 2 and Fig. 9, the bottom wall 110 and roof 100 of the CCD camera assembly 1 of the embodiment of the present invention are equipped with
It is responsible for the camera lens of shooting picture, in this way, the vertical angle of view of the camera lens of peripheral wall 120 is not necessarily extend up and down the two of CCD camera assembly 1
Pole, it is possible to using wide-angle lens without reusing fish eye lens.As shown in Fig. 9, Figure 11 and Figure 13, each wide-angle lens
Angle control area reduction, repeatedly be overlapped and cover region greatly reduce.The no longer inscribed CMOS of imaging region at
On the inside of picture rectangle, but the rectangle imaging region overlapped with CMOS chip 100%, so CMOS utilization rates have obtained maximum lift
(100% is all valid pixel).Lens distortion has obtained good control, in splicing, especially seam at the two poles of the earth of camera
Good control is obtained.
