Problems solved by technology

However, it is difficult to keep the installation angle unchanged from the previous installation angle. Once there is a small change in the installation angle, it will have a great impact on subsequent use.
At this time, it is necessary to re-measure whether the installation angle of the scanner is suitable, and repeat the tedious operation during the initial installation

Embodiment Construction

[0046]The present invention will be described in further detail below with reference to the accompanying drawings. For the laser scanner that scans in the direction of the trolley, the method of measuring the deflection angle of the installation at the initial installation is described.

[0047] (1) Adjust the installation angle after installing the scanner for the first time: measure the installation position P1 of the scanner on the gantry crane frame, including the position in the X-axis direction, the Y-axis direction and the Z-axis direction; the installation auxiliary program SPSS is used as an existing Some mature software converts the polar coordinates of the scanning point fed back by the scanner into rectangular coordinates through coordinate transformation, and displays the graphical interface on the computer; two reference objects are placed 25 meters apart on the ground, and the distance can be within 3 It fluctuates within meters, so that the scanning line of the...

Abstract

The invention provides a deflection-angle measuring method and system for installing a laser scanner on a port shore bridge and aims at changing the situation that the existing operation process for detecting and adjusting the installation angle of the laser scanner is tedious and wastes time and labor. The detection system is characterized in that after the scanner is primarily installed and theinstallation angle is adjusted properly, a sea-side crossbeam and a land-side crossbeam of the shore bridge are respectively provided with a reference object; when the scanner is disassembled and needs to be reinstalled, secondary installation and angle adjustment of the scanner can be finished in a very-simple and assisting manner, installers adjust the installation angle of the scanner, assistants observe whether the reference objects preinstalled on the sea-side crossbeam and the land-side crossbeam of the shore bridge can be scanned simultaneously on a graphic interference, and if the twopreinstalled reference objects can be scanned simultaneously, the work for adjusting the installation angle of the scanner is ended.

Description

technical field [0001] The invention relates to a deflection angle detection technology, in particular to a deflection angle measurement method and system installed by a laser scanner of a port crane. Background technique [0002] The quay crane is an important equipment for container terminal operations, responsible for loading and unloading operations. In order to reduce the work intensity of drivers and improve work efficiency, more and more ports use quay cranes (semi) automated operations. In the process of automated operation, in order to reduce energy consumption and improve operation efficiency, the spreader must follow a parabolic path, which requires scanning equipment and corresponding programs to scan the distribution of containers on the ship in real time to form the contour distribution of containers. [0003] The ship container contour scanning system uses a laser scanning device to scan the shape of the ship. The laser scanning device includes two 2D laser s...
