Operating device, operating method, and program therefor
Exterior orientation parameters of a camera are easily determined by, for example, a reference image being obtained by photographing a building 131 with a camera 112 , in which exterior orientation parameters are determined, while a vehicle 100 travels, and a comparative image being simultaneously obtained by photographing the building 131 with a camera 113 , in which exterior orientation parameters are undetermined. Then, points that match between the reference image and the comparative image are selected, and relative orientation and scale adjustment using a predetermined scale are performed, whereby the exterior orientation parameters of the camera 113 are calculated.
1. An operating device comprising:
processing circuitry configured to
obtain reference images by photographing an object at multiple timings with a first camera while a vehicle travels and obtain comparative image by simultaneously photographing the object at multiple timings with a second camera at the same time as the first camera while the vehicle travels, the first camera being fixed to the vehicle and having exterior orientation parameters with respect to the vehicle, which are predetermined, and the second camera being fixed to the vehicle and having exterior orientation parameters with respect to the vehicle, which are undetermined,
select points that match between the reference images and the comparative images,
obtain data of superposed matched points by superposing data of the matched points between the reference images and the comparative images, which are simultaneously photographed at the multiple timings,
perform relative orientation based on the data of the superposed matched points and calculate the exterior orientation parameters of the second camera by adjusting the scale in accordance with a predetermined scale.
2. The operating device according to claim 1 , wherein the multiple reference images are obtained by photographing different objects.
