基于二维激光测距仪的农机具作业高度测量研究

gricultural implement and working object to maintain the stability of the operating height can improve the quality and efficiency. To provide accurate operating height between implement and working objects, this paper proposes a kind of agricultural implement operating height measurement method based on 2D Scanning Laser Range Finder(2D-SLRF). The row information that obained by 2D-SLRF scanning vertical iscorrected using anAtitude and Heading Reference System(AHRS). Then, the data is analysised based on mode principle, and different distance level sets are collected. The weighted fusion algorithm is used to calculate the agricultural implement operating height. The test results show that the 2D-SLRFis mounted at 1510mm height position, the identification object (ground) accounting for more than 30.35%, the RMS error is 12.15mm, the maximum error is 19mm; the 2D-SLRF is mounted at 1880mm height position, the identification object (ground) accounting for more than 29.61%, the RMS error is 4.32mm, the maximum error is 15mm.
