Digital aerial photogrammetry equipment for improving measurement precision

Abstract

An auxiliary mechanism comprises an outer cover and a telescope, the telescope is arranged in the outer cover, a camera is arranged on the inner wall of the outer cover, a telescopic assembly is arranged outside the telescope, a connecting assembly is arranged outside the outer cover, a supporting plate is fixedly connected to the inner wall of the outer cover, and the supporting plate is fixedly connected with the telescopic assembly. The invention relates to the technical field of photography. According to the digital aerial photogrammetry equipment capable of improving the measurement precision, when the shooting range is large, a driving motor drives a circular plate to rotate, so that a rotating strip drives an upper connecting column to move, a sliding plate drives a telescope to move to a shooting part of a camera, and the shooting definition is enhanced through focusing of the telescope; the stability of the telescope is enhanced through the connection of the sliding strip and the sliding groove, the situation that the shooting definition is reduced due to the poor stability of the telescope is avoided, and the problem that the measurement precision is poor in the surveying and mapping or surveying process of an existing aerial photography technology is solved through the combination of the structures.

Description

technical field [0001] The invention relates to the technical field of photography, in particular to a digital aerial photogrammetry device for improving measurement accuracy. Background technique [0002] Aerial photography, also known as "aerial photography", refers to the method of photographing ground or aerial targets from the air by using a special aerial camera installed on an aircraft; it can reduce the amount of field work, reduce labor intensity, and is not affected by geographical conditions. It has the advantages of fast, accurate and economical; it is widely used in surveying and mapping maps, geology, hydrology, mineral deposits and forest resource investigations, agricultural production evaluation and planning of large factories, mines and towns, railways, highways, high-voltage transmission lines and oil pipelines It can also be used for aerial reconnaissance, news reports, and shooting movies and TV shows. [0003] In the prior art, when aerial photography ...
