基于CAN总线的丘陵山地果树冠层激光点云测量系统
Laser Measurement system of Hilly Fruit Tree Canopy Volume based on CAN bus
为了克服丘陵山地果园地面不平整和果树种植不规整等因素对果树冠层体积、疏密度等参数激光测量方法的影响，本文搭建了适合丘陵山地果树冠层参数测量的激光点云测量系统。系统采用姿态航向参考系统校正拖拉机车体姿态变化，全球定位系统接收机精确定位拖拉机车体三维坐标，采用CAN 总线构筑各模块之间通信的数据链路。测试结果表明，测量系统具有较高的空间测量分辨率，测量的激光点云云图能较真实地反映荔枝树靶标树冠的形状与轮廓特征。本文为丘陵山地果树冠层体积、疏密度等参数的精确测量提供了前期研究基础。
In order to overcome the problem of uneven hilly environment and irregular planting on measuring fruit tree canopy volume, a platform for measuring hilly fruit tree canopy volume by laser was set up．In the platform, attitude heading reference system was adopted to rectify the variance of tractor attitude, RTC-DPGS receiver was used to get 3D geodetic coordinates of tractor, and system modules communicated with each other based on CAN bus. Tests result show that the system had high measuring precision and the shape of laser points cloud gotten from litchi tree target was consistent with original picture of target. Primary research for measuring hilly fruit tree canopy parameters accurately was provided in this paper.
