Camera measurement based automatic leveling system and method of spreading machine

Abstract

The invention discloses camera measurement based automatic leveling system and method of a spreading machine. The method comprises the steps of: firstly, establishing a leveling system formed by four manual cooperation marks fixed on an ironing plate of the spreading machine and a camera measurement system, obtaining offsets of the manual cooperation marks fixed on the ironing plate of the spreading machine relative to the initial position through rapid and accurate measurement of a camera system, thereby obtaining offset of the ironing plate of the spreading machine relative to the initial position; and secondly, feeding the measurement result back to a control system of the spreading machine, thereby realizing the rapid and automatic leveling the spreading machine. The camera measurement based automatic leveling system and the method of the spreading machine have the advantages of non-contact, full site, high accuracy, easy automatic implementation and the like. The invention is simultaneously suitable for the field of other machines of a leveling machine and the like, and can improve the leveling quality and the automation of the leveling machine.

Description

technical field [0001] The invention relates to the fields of digital camera measurement, paver leveling parameter measurement, automatic control and the like, and further relates to an automatic leveling system and method for a paver based on camera measurement. Background technique [0002] Automatic leveling systems have been widely used in construction machinery such as pavers, graders, and milling machines. With the development of high-speed highways, the actual engineering application has higher and higher requirements for leveling precision, which puts forward higher requirements for leveling control systems. In terms of the technical development of the automatic leveling system, the automatic leveling system of the paver is the most typical. [0003] The leveling systems that have been used in paver mainly include leveling methods based on steel wires, mechanical balance beam leveling methods, and ultrasonic (multi-sonar) non-contact balance beam leveling methods. ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem solved by the present invention is: to overcome the deficiencies of the existing leveling technology, to propose a paver automatic leveling system and method based on camera measurement, using the camera measurement method, through the rapid and accurate measurement of the camera system to obtain the The offset of the manual cooperation mark on the paver screed relative to the initial position, so as to obtain the offset of the paver screed relative to the initial position, and then feed back the measurement results to the paver control system, so as to realize the fast and automatic paver leveling
