Embodiment 1
[0058] A certain type of photoelectric theodolite, with a caliber of 650mm, a focal length of 4m, and a field of view of about 0.2°×0.2°, implements the method announced by the present invention as follows:
[0059] (1) Photoelectric theodolite leveling and positioning
[0060] Move the photoelectric theodolite and the vehicle to the flat and hard ground and level it, use the differential GNSS system to measure the site position, and establish the center coordinate system with the site coordinates as the origin.
[0061] (2) Arbitrary zero reference determination
[0062] According to the current time and the position of the sun relative to the equipment, estimate the north position, and reset the photoelectric theodolite encoder to zero in this direction to determine the zero reference.
[0063] (3) Sun position measurement
[0064] Turn the photoelectric theodolite, and manually adjust the lower edge of the sun to enter the field of view of the device according to changes ...
