The paper put forward the system error evaluation method of 3D scanning system for gangue monitoring; analyzed
system errors including integrated error which can be avoided, and measurement error which needed whole analysis;
firstly established the system equation after understanding the relationship of each structure. Then, used error
independent effect and spread law to set up the entire error analysis system, and simulated the trend of error changing
along X, Y, Z directions. At last, it is analytic that the laser rangefinder carries some weight in system error, and the
horizontal and vertical scanning angles have some influences on system error in the certain vertical and horizontal
scanning parameters.
