Forest measurement method, forest measurement system and computer program

摘要

Forest measurement is carried out by flying unmanned aerial vehicles equipped with lidar sensors.The rotation axis or the swing axis of the rider sensor is mounted on an unmanned aerial vehicle in such a manner as to advance the direction of the vehicle body.How to measure forestUsing the rider sensorMeasurement of the surrounding space by changing the direction of emission of the laser pulse while changing at a predetermined angleForest distance LUnmanned aerial flight speed vThe number of laser pulses emitted simultaneously in the same angular direction is nThe frequency of laser pulses emitted in the same angular direction isConstant pitch α とするとき、V / (F, n) α The relative value of L is within a predetermined rangeThis paper carries out the forest measurement for the forest using the rider sensor while flying unmanned aerial vehicle.
