摘　　要：森林的规划利用需要对森林资源进行精确估测。在新的作业环境下,需要研究新型树木信息采集装置来适应复杂的林区环境同时实现数据的高效采集,自行式树木测量激光扫描仪是能够实现林分数据高效采集的设备之一。为了实现扫描仪在林中机动灵活地移动,并迅速架设,保证平稳工作,需要开发一个扫描仪车载自行机构。机构由车、调平平台、桅杆和云台四部分组成。通过对坡度、灌木高度、树高和树木坐标等数据的采集和分析,确定了调平平台的调平角度、桅杆的初始高度和工作高度、云台的水平和竖直方向的旋转角度、车的尺寸、车的牵引力和额定功率等主要工作参数。Forest planning and utilization requires accurate estimation of forest resources. Under the new op- erating environment, a new type of tree information collection device is needed to adapt to the complex for- est environment and to achieve the efficient data collection. Laser scanner of self-propelled tree measure- ment is one of the devices which can achieve efficient collection of stand data. In order to realize the scanner moving flexibly in the forest, to install the mechanism rapidly and to ensure smooth operation, a vehicle self-propelled mechanism of scanner was developed. The mechanism was composed of four parts： car, level- ing platform, mast and PTZ. Based on the data collection and analysis of slope, shrub height, tree height and tree coordinates in the study area,the main parameters were determined,including leveling angle of the lev- eling platform, the initial height and working height of the mast, the horizontal and vertical rotation angle of the PTZ,the size of a vehicle,the traction and rated power of a vehicle.
