Method, system, and device for flagstick positioning based on laser rangefinder telescope

A system for flagstick positioning based on a laser rangefinder telescope, comprising:

• a data acquisition module, configured to obtain, in response to the laser rangefinder telescope is rotated such that a ranging light emitted by the laser rangefinder telescope is aligned with a flagstick, rotation information and position information of the laser rangefinder telescope, and analyze the ranging light to obtain a distance between the laser rangefinder telescope and the flagstick;
• a first magnetic declination correction module, configured to correct, according to the rotation information of the laser rangefinder telescope and the distance, a magnetic declination of the flagstick obtained at a same moment of obtaining the distance to thereby obtain a first corrected magnetic declination;
• a second magnetic declination correction module, configured to correct, according to the rotation information of the laser rangefinder telescope in combination with a preset linear model of rotation acceleration versus magnetic declination offset angle, the magnetic declination of the flagstick to thereby obtain a second corrected magnetic declination;
• and
• a flagstick positioning module, configured to perform, according to the position information of the laser rangefinder telescope, the distance, the first corrected magnetic declination and the second corrected magnetic declination, a positioning analysis on the flagstick to thereby obtain position information of the flagstick;
• wherein the data acquisition module, the first magnetic declination correction module, the second magnetic declination correction module, and the flagstick positioning module are software modules stored in a memory and executable by a processor coupled to the memory.
