Posture of camera in three dimensional system of digital camera and basic research concerning
Yasuyuki MIYAKI
My laboratory has already developed a three dimensional surveying system with relative orientations. The method is possible posture in three dimensional system by easy measurement in outdoor like the construction site and taking a picture of measurement thing from some several directions.
It calculates the interior orientation parameter by not using three dimensional ruler,
and using special software. The exterior orientation parameters can calculate to specified in common points to manual images. (It is called pass point.) The exterior orientations parameter exerts a big influence on accuracy by method of selecting pass point. Moreover, the posture of camera changes by influence such as sudden winds, there is a possibility that exterior orientation parameter is changed. The following things were examined in this experiment.¡How does the output result change by the position of pass point? ¢How much do you influence the result because the posture of the camera change?
Consequently it became the following.
1. The method of arranging pass point is three more dimensional than information two dimension accuracy improves.
2. This experiment is the best accuracy to arrangement of pass point at the center of the image.
3. The change in the posture of about five degrees doesn¡Çt have the so much influence inaccuracy.
