This technology is a distance-measuring drone that carries a support pole and a laser surveying device on a hovering aircraft. It communicates with an external device placed at a ground reference point to measure the target distance to the survey point. The adjustment mechanism mounted on the aircraft changes the position and angle of the support pole based on remote control signals from the external device, allowing for precise alignment of the surveying device even while in the air.
Conventional distance surveying required mounting equipment on tripods and manually moving them from point to point. Even when surveying equipment was mounted on drones, it was difficult to adjust the height and beam angle during flight. Consequently, in rugged terrain or areas with many obstacles, it was often impossible to secure a clear path for laser transmission and reception, leading to reduced efficiency and accuracy.
This technology features a first adjustment mechanism that moves the surveying device vertically along the support pole, a second adjustment mechanism that moves it forward and backward along a guide rail, and a third adjustment mechanism that tilts the bed to align the orientation angle of the device, all driven by motors and rack-and-pinion systems. It can be applied to civil engineering and construction site surveying, cadastral and topographical surveys, and distance measurement in mountainous or riverine areas that are difficult for personnel to access, thereby reducing the need for manual labor and enabling rapid, remote targeting of desired points.
