• Why do many miscellaneous points appear in the scene after calibration?OPEN +
  • The first case may be that the miscellaneous points are not completely removed when the T-bar is calibrated; calibration is passed under critical conditions; if miscellaneous points appear during the calibration process, they certainly exist in the subsequent data acquisition. The other case may be that the equipment in the scene reflect light; it is possible that the equipment is moved out of the scene at the time of calibration but are moved in after calibration.


  • How can I create a coordinate system?OPEN +
  • A coordination system is created at the time of calibration, and the geodetic coordinate system cannot be changed randomly.


  • Why do I fail to pass the calibration many times?OPEN +
  • First confirm whether the configuration file is loaded, and then check whether the setting of the length of the calibrated T-bar is correct. If these two steps are confirmed to be correct, then further confirm whether the miscellaneous points in the scene have been eliminated at the time of calibration.


  • Why is the earth in the software in the vertical direction?OPEN +
  • Because the Z axis or the Y axis is set to be upward in the previous settings file; if the positions of the coordinate axes are changed, the geodetic coordinate system will change accordingly. Now you need to make recalibration.
