The proposed arrangement for vertical angle calibration is based on determining the trigonometric angle using the reference scale of length for vertical readings employing the tacheometer and another reference measure of length for the distance from the tacheometer axis to vertical scale determination.
Those methods being: point collection by means of an electronic tacheometer working in the surface scanning mode and the collection of surface points by means of photogrammetric measurements.
The precise 3D position of each mark was determined using the digital tacheometer and those data were transferred to the photogrammetric Photo-Mod project.
The proposed arrangement for vertical angle calibration is based on the trigonometric angle determination using the reference scale of the length for vertical readings by the tacheometer and another reference measure of length--for distance from the tacheometer's axis to the vertical scale determination.
Obviously the calibration with single calibration plate can not be performed at the entire range of tacheometer angular measurements (360[degrees]) since the plate will not be visible on the images.
