Abstract

The invention relates to the technical field of unmanned aerial vehicle oblique photography detection, and particularly discloses an unmanned aerial vehicle high-precision full-frame oblique photogrammetry device. The device comprises an unmanned aerial vehicle body. A plurality of rotor arms are uniformly connected to the unmanned aerial vehicle body; a driving motor is fixed on a lower surface of an outer end part of each rotor arm; and propellers are arranged at an upper end, penetrating through the rotor arms, of an output shaft of the driving motor, a rectangular block is connected to thecenter of the lower surface of the unmanned aerial vehicle body, an adjusting motor is fixedly arranged on the front side surface of the rectangular block, a rotating cavity is formed in the rectangular block, and a large gear is arranged in the middle of the rotating cavity. According to the device, a photographing angle and a wide angle can be adjusted in real time in actual use; and the shooting angles of the four second high-definition cameras can be adjusted at the same time through one adjusting motor, one adjusting motor does not need to be arranged at the end of each second high-definition camera, equipment cost is greatly reduced, and more importantly, a load capacity of the whole unmanned aerial vehicle is effectively decreased.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle oblique photography detection, and specifically discloses a high-precision full-frame oblique photogrammetry device for unmanned aerial vehicles. Background technique [0002] Oblique photography technology is a high-tech developed in the field of international surveying and mapping in recent years. It overturns the previous limitation that orthophoto images can only be taken from a vertical angle. By carrying multiple high-definition cameras on the same flight platform, its high-definition Set it to five, so that images can be collected from five different angles such as one vertical and four oblique at the same time, which introduces users to a real and intuitive world that conforms to human vision. Object texture information can also generate a real 3D city model through advanced positioning, fusion, modeling and other technologies. [0003] At present, the five high-definition...
