Abstract

The invention provides an on-line calibrating device of a laser sensing three-dimensional measure system, and a calibrating method thereof. The device comprises a laser scanner, an inertia measuring unit, a laser distance measuring sensor, a horizontal moving platform, a guide rail, an adjustable platform, two calibrating boards having different structure parameters and a computer, wherein the inertia measuring unit is mounted on the laser scanner, the laser scanner and the laser distance measuring sensor are both mounted on the horizontal moving platform, the horizontal moving platform does linear motion along the guide rail, the adjustable platform can be controlled through a level meter to the level, and the calibrating boards are arranged on the adjustable platform according to requirements. The device is advantaged in that computational complexity is low, the calibrating boards are simple to manufacture, the calibrating process is simple to operate, and on-line and off-line calibration can be realized.

Description

technical field [0001] The invention relates to an online calibration device and calibration method for a laser sensor three-dimensional measurement system, in particular to a laser scanner and an inertial measurement unit that uses structured calibration boards with different structural parameters as scanning objects and combines the data of each sensor to establish a laser scanner and an inertial measurement unit. The coordinate relationship, and then the method and device for demarcating the relative relationship between the two. Background technique [0002] In iron and steel, energy and other enterprises, there is a large demand for raw materials such as ore and coal, and a balanced and stable raw material supply chain is the basis for enterprise production. These raw materials are often stored in the stockyard in the form of piles, and the volume measurement of large piles provides the necessary inventory data for its raw material logistics management. In order to mee...
