The invention discloses an image processing technique based electronic centering system of a total station and an automatic centering compensating method thereof, and aims at solving the problem of low centering accuracy. The system is characterized in that a CCD image sensor is mounted on a centering optical path of the total station and used for acquiring three centering images in three directions of a dial, and the three centering images are processed and analyzed to obtain coordinates of ground points and center line centers of the images, and then the ground points are treated as the immobile points for overlapping the three images; a right-angle coordinate system is built; a centering error vector is solved, and accordingly the actual offset of the ground points and the cross line center is solved; then the angle deviation is calculated and added to the direction value for correcting, so as to obtain accurate direction value. With the adoption of the system, the centering error of the total station is accurately measured, and the direction value is corrected, the manual centering accuracy is improved, and the measuring time is saved; the system is high in practical value.
Description
technical field [0001] The invention relates to the technical field of precision measurement and positioning, in particular to an electronic centering system of a total station and an automatic centering compensation method. Background technique [0002] At present, there are centering errors and aiming errors in the angle measurement process of the total station. Nowadays, the automatic aiming technology is very mature. The equipment has the automatic aiming function of the total station ART. Its top technology makes the data more accurate, and the aiming error can be controlled at a higher accuracy. However, the alignment of the total station still requires manual operation, and some of them must be forced to align. The error generated by manual control has a great influence on the observed value, especially when conducting precision wires and precision testing, the error of manual centering (ie eccentricity) ranges from about 0.3 to 1 mm. The formula for the centering e...
