GPS-installed all-azimuth camera and spatial data collecting device

1. A GPS-installed all-azimuth camera, comprising at least a pair of GPS antennas disposed on up and down in parallel to each other and, a plurality of cameras which are disposed on a plane running in parallel to said GPS antennas and are capable of obtaining images in all azimuths, and a case for accommodating said cameras and said GPS antennas, wherein a reference position of said GPS antennas is concurred with a image reference position of said cameras.

2. A GPS-installed all-azimuth camera according to claim 1 , wherein said pair of GPS antennas are installed on up and down with a predetermined distance away, and wherein said cameras are disposed between said GPS antennas.

3. A GPS-installed all-azimuth camera according to claim 1 , wherein said case is designed in spherical shape.

4. A GPS-installed all-azimuth camera according to claim 1 or 3 , wherein optical axes of said plurality of cameras concur with each other at the center of said case.

5. A GPS-installed all-azimuth camera according to claim 3 , wherein the cameras are disposed also in zenith direction, which an image reference position of said cameras concur with an reference position of said GPS antennas.

6. A GPS-installed all-azimuth camera according to claim 2 , wherein a plurality of pairs of said GPS antennas are installed with said cameras between said GPS antennas.

7. A GPS-installed all-azimuth camera according to claim 1 , wherein a plurality of GPS antennas are superposed and are designed as a single base plate and said plurality of cameras are disposed around said base plate.

8. A GPS-installed all-azimuth camera according to claim 7 , wherein said case is designed in disk-like shape.

9. A spatial data collecting device, comprising a GPS-installed all-azimuth camera according to claim 1 , an azimuth sensor, and an arithmetic processing device, wherein said arithmetic processing device calculates a coordinate data at an image pickup point based on signals from said GPS antennas and calculates three-dimensional coordinates of an object to be measured in the picked-up image based on the coordinate data at the image pickup point as obtained, on the picked-up image, and on a signal from said azimuth sensor.

10. A spatial data collecting device according to claim 9 , further comprising a storage unit, wherein a picked-up image is associated with the obtained three-dimensional coordinates and is stored in said storage unit.

11. A spatial data collecting device according to claim 9 , further comprising an inertial measurement unit, wherein in case where a position information cannot be obtained by said GPS antennas, the position information is supplemented by said inertial measurement unit.

12. A spatial data collecting device according to claim 9 , wherein the azimuth detected by said azimuth sensor concurs with one of optical axes of said cameras.

13. A spatial data collecting device according to claim 11 , wherein said arithmetic processing device compensates the position information determined by said inertial measurement unit based on the position information by said GPS antennas periodically or at real time.
