Embodiment
The present invention is described in further details with reference to the accompanying drawings and examples.
A kind of satellite VR panoramic imaging devices for space imaging, including：More cameras 1, imaging administrative unit, satellite
Primary load bearing frame 2.Camera mounting bracket is installed, more cameras 1 are installed on camera mounting bracket on satellite primary load bearing frame 2
On.Imaging administrative unit connects every camera 1, and imaging administrative unit can control every camera 1 to shoot.Multiple cameras 1 regard
Field splicing can form 360 degree of field angle.The structure chart of satellite VR panoramic imaging devices is as shown in Figure 1.
Satellite VR panoramic imaging devices are continuously spliced for multiple cameras 1, consider system weight, power consumption, imaging
The factors such as quality, visual field distortion, more cameras 1 select 6 in present embodiment, and 6 cameras 1 are uniformly installed on camera and install
On stent, camera mounting bracket is located on satellite primary load bearing frame 2.Wherein camera mounting bracket shape is regular hexagon (camera
The cross section of mounting bracket is regular hexagon), the cross section of satellite primary load bearing frame 2 is regular hexagon, and camera mounting bracket is pre-
It is embedded in installation satellite primary load bearing frame 2, in Fig. 1 cannot visible directly camera mounting bracket.Satellite primary load bearing frame 2 can be with
To be provided with the installation site of camera mounting bracket on the basis of existing primary load bearing frame, or install branch with camera
Frame, which is integrated, to be formed, the satellite primary load bearing frame 2 as equipped with camera mounting bracket.In camera mounting bracket regular hexagon
Each side on installation one camera, 1,6 cameras 1 central shaft (i.e. the central shaft of camera mounting bracket) and satellite that are formed
Z-axis (satellite hub axis) overlap and be uniformly distributed.It is as shown in Figure 2 that 6 cameras 1 splice schematic diagram.Every 1 field angle α of camera
=60.1 ° (every 1 field angle α >=60 ° of camera, when purpose is shot at the same time for 6 cameras 1, and carry out the visual field of 6 cameras 1
Splicing, can complete once to realize the collection of 360 ° of image or video from the earth to space), adjacent two cameras 1 overlap visual field A
=0.1 °, realize 360 ° of all standings of panorama, 6 cameras 1 at the same time shooting image when, utilize shooting of the computer to 6 cameras 1
Picture spliced, splicing picture is 360 ° of panorama sketch, and as the visual field of 6 cameras 1 is spliced, so 6 cameras 1
Form VR panorama cameras.The reference for assembling of wherein 6 cameras 1 is identical with the reference for assembling of satellite, ensure that VR panorama cameras
Splicing precision, i.e., on the basis of some component of satellite, then during satellite rotational angle β, benchmark rotates β, and 6 cameras 1 also rotate
β.Single camera 1 is high-resolution, the camera 1 of high dynamic range, and 1 resolution ratio of camera is 3800 × 2700, up to 10,000,000
Pixel, field angle are 60.1 ° × 45 °, and area coverage is 414km × 578km at the 500km of ground, corresponding ground target
Resolution ratio is about 200m, can recognize that the targets such as coastline, mountain range, city.1 quantity of camera of VR panorama cameras, field of view angle and
Installation site, is to realize that being covered as target with 360 ° of panoramas carries out choosing setting.
Due to the limitation of the installation site and angle of camera 1, the intermediate space of two cameras 1 has certain blind area, warp
Cross the calculating to field angle and image-forming range, the space target at 500km can be imaged, and can realize 360 ° it is seamless spliced,
Image-forming range is as shown in Figure 3 with areas imaging.Assuming that the distance between 1 two focal planes of camera D=20cm, the focal plane of camera 1 with
The distance between satellite hub S=20cm, orbit altitude H=500km, the field angle of each camera 1 is α=60.1 °, according to meter
Calculate camera 1 and splice blind area distance M=114.6m, two 1 lap widths of camera are L=872.5m in H=500km, then camera 1
Within 1 focal plane 114.6m of camera it is blind area after splicing, when orbit altitude is 500km, two cameras 1 are overlapped with 872.5m,
That is the space beyond satellite 114.6m can realize seamless shooting.
Imaging administrative unit can control every camera 1 shoot (while shoot, part at the same shooting or wherein one clap
Take the photograph), and gather the image of every camera 1 respectively and be stored in spaceborne solid-state disk.Imaging administrative unit is to be programmed by FPGA
Circuit board, which is integrated in satellite hub machine.
The present invention can also include main load camera 3, if comprising main load camera 3, main load camera 3 is installed on satellite
On primary load bearing frame 2, main load camera 3 is located in the z-axis of satellite, and 6 cameras 1 are equal centered on the main load camera 3 of satellite
Even distribution, the spaceborne integrated design overall structure figure containing main load camera 3 are as shown in Figure 4.Main load camera 3 is by satellite hub
Machine controls.Main load camera 3 is installed on satellite primary load bearing frame 2, and satellite primary load bearing frame 2 both provided for VR panorama cameras
Mounting surface, and as unit installing plate on the hood and star of main load camera 3, effectively increase the functional density of satellite, subtract
Moonlet volume and weight.
The image-forming range of all imaging devices (VR panorama cameras and main load camera 3) with areas imaging is filled according to imaging
Installation site and angle, the field angle for putting itself are calculated.
