Square upwards 360 degrees omnidirection shooting.In the vertical direction, the shooting angle range of wide-angle lens is between 95 degree to 117 degree.
The wide-angle lens on peripheral wall 120 can realize that picture is superimposed with the wide-angle lens on roof 100 or bottom wall 110 as a result, so as to
With the undertaking and transition of the shooting picture in shooting picture and vertical direction on direction of improving the standard, so as to improve entirety
The shooting effect of shooting picture is realized and is shot without dead angle.
The fringe region image quality of wide-angle lens it is almost consistent with center (using aspherical mirror wide-angle lens in its edge
The image quality in region at least corresponds to 90% or more of central area image quality).Using wide-angle lens as the first camera 20, second
The utilization rate of 1 shooting picture of CCD camera assembly can be improved in the camera lens of camera 30, and the pixel that shooting picture can be improved is close
Degree reduces edge interpolation.
As shown in figure 18, in some embodiments of the utility model, the length-width ratio of picture captured by wide-angle lens is P,
4/3≤P≤16/9.It is understood that the length of picture and the ratio of width using wide-angle lens shooting can be 4:3.
It may be 16:9 using the length of picture and the ratio of width of wide-angle lens shooting.Certainly, the picture of wide-angle lens shooting
Length and the ratio of width can also be the length of 13:9 or picture and the ratio 14:9 of width, the length of picture and wide
The ratio of degree may be 15:9.Thus, it is possible to improve the effect of shooting picture.
As shown in figure 4, some embodiments according to the present utility model, second camera 30 can be two, respectively the
One sub- camera and the second sub- camera, the first sub- camera are located at bottom wall 110, and the second sub- camera is located at roof 100, and second
Sub- camera is located at the surface of the first sub- camera.It is understood that roof 100 is equipped with a second camera 30.
Bottom wall 110 is equipped with a second camera 30.The second camera on second camera 30 and bottom wall 110 on roof 100
30 faces.For example, the second camera 30 on wall can be located along the same line with the second camera 30 on bottom wall 110.By
This, the second camera 30 that can use on roof 100 shoots sky, and the second camera 30 that can use on bottom wall 110 is clapped
Ground is taken the photograph, it, can be with so as to realize omnidirectional shooting using the 20 shooting level direction of the first camera on peripheral wall 120
Realize that the image quality of whole day ball full-view image is unified.
According to the camera of the utility model embodiment, comprising: CCD camera assembly, the CCD camera assembly are as described above
CCD camera assembly 1.
According to the camera of the utility model embodiment, by the way that the first camera 20, roof 100 and bottom is arranged in peripheral wall 120
At least one of wall 110 is equipped with second camera 30, can use the scene on 20 shooting level direction of the first camera, also
It can use second camera 30 on roof 100 or bottom wall 110 and shoot scene on vertical direction, such as sky or ground,
So as to expand the shooting visual angle of CCD camera assembly 1, the shooting performance of CCD camera assembly 1 is improved.
Below with reference to Fig. 1-Figure 18 detailed description according to the CCD camera assembly 1 of the utility model embodiment.It is worth understanding
It is, it is described below to be merely illustrative, rather than to the concrete restriction of the utility model.
As Figure 1-Figure 4, CCD camera assembly 1 includes the duplicate wide-angle lens of shell 10 and 7.On peripheral wall 120
5 are evenly distributed, each camera lens is separated by 72 degree.The roof 100 and 110 center position of bottom wall of CCD camera assembly 1 respectively have one wide
Angle mirror head, and each wide-angle lens can install optical filter 210.As shown in figure 5, the horizontal field of view angle of each wide-angle lens
(H FOV) is 130 degree, and vertical field of view angle (V FOV) is 95 degree, aperture F2.8.As shown in figure 18, wide-angle lens takes
The length of picture can be 4L, and the width for the picture that wide-angle lens takes can be 3L, the picture that wide-angle lens takes
Long and wide ratio is 4:3.
As shown in fig. 6, CCD camera assembly 1 further includes bracket 200, wide-angle lens is installed by bracket 200 to shell 10.Branch
Frame 200 includes boss 201.Boss 201 is in a ring.Boss 201 includes the first screw thread, and optical filter 210 includes the second screw thread, the
Two screw threads can be cooperatively connected with the first screw thread.
In the related technology, panorama camera is all using horizontal equidistant camera lens layout design scheme, is mostly 2 camera lens of level, 4
Camera lens, 6 camera lenses, 8 camera lenses to tens camera lenses design scheme.For example, as shown in fig. 7, panorama camera includes 6 camera lenses.Mirror
Head quantity is usually even number.Camera lens is usually the fish eye lens of 180 degree or more.The upper surface of camera and following no individual mirror
Responsible shooting is that the lens edge of the camera lens vertical direction by level one week is covered, as shown in Figure 8.In order to
So that sky and ground can have a picture, form 360 degree * 360 whole day ball full-view image spent, the camera lens of horizontal direction it is vertical
Visual angle must extend to upper and lower the two poles of the earth, meet or exceed 180 degree, as shown in Figure 10 and Figure 12, this is would have to using 180 degree
And panorama camera is made with the fish eye lens of upward angle of visibility.
As shown in Figure 10-Figure 12, due to using fish eye lens, so that the picture entirety image quality of panorama camera shooting is not united
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 of the fish eye lens for being camera surrounding is spliced jointly, effect is very poor.And
And in the horizontal direction, more camera lens pictures are overlapped 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 lower 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 obvious.
As shown in Figure 15-Figure 16, the design of CCD camera assembly 1 image quality of the utility model embodiment is very uniform, entire picture
It is all the relatively good region of image quality, the CCD camera assembly 1 of the utility model embodiment replaces fish eye lens using wide-angle lens.Such as
Shown in Fig. 9, Figure 11 and Figure 13, wide-angle lens distorts to have obtained good control, and in splicing, the Liang Jichu of especially camera is connect
Seam has obtained good control.
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 utility model embodiment are equal
Camera lens equipped with responsible shooting picture, in this way, the vertical angle of view of the camera lens of peripheral wall 120 is not necessarily extend the upper of CCD camera assembly 1
Lower the two poles of the earth, 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
The area reduction of the angle control of camera lens, the region for being overlapped and covering repeatedly greatly reduce.The no longer inscribed CMOS of imaging region
Imaging rectangle on the inside of, but the rectangle imaging region being overlapped with CMOS chip 100%, so CMOS utilization rate has obtained maximum
It is promoted (100% is all valid pixel).Lens distortion has obtained good control, in splicing, the especially Liang Jichu of camera
Seam has obtained good control.
