High-altitude structure image pixel calibration auxiliary device

Abstract

The invention relates to the high-altitude structure appearance detection technical field, and discloses a high-altitude structure image pixel calibration auxiliary device comprising a plurality of clamps embedded on an unmanned plane landing rack; the plurality of clamps are evenly arranged on the landing rack on two sides of the unmanned plane, and used for fixing a basic rod with a calibration piece; the calibration piece is vertically arranged on one side of the basic rod and used for calibrating the high-altitude structure appearance sizes; the portion, arranged in the unmanned plane, of the auxiliary device has equal mass with the portion, exposed outside the unmanned plane, of the auxiliary device. Various parts of the auxiliary device are evenly and symmetrically arranged on two sides of the unmanned plane, will not affect the unmanned plane flying stability, thus ensuring the image acquisition and calibration work to be smoothly carried out; the high-altitude structure image pixel calibration auxiliary device is low in cost, easy to promote, easy in applications, and has obvious market application values.

Description

technical field [0001] The invention relates to the technical field of appearance detection of high-altitude structures, in particular to an auxiliary device for image pixel calibration of high-altitude structures. Background technique [0002] In civil engineering, concrete structures will have cracks due to various reasons, affecting their use, durability and even safety. Accurately grasping the shape, length, width, etc. of concrete components plays a vital role in correctly judging the state of concrete components and proposing a scientific and reasonable treatment plan. Therefore, the detection of cracks in the maintenance work of the structure construction later Can not be ignored. Although the traditional artificial surface detection measurement method has the advantages of direct method and strong controllability, it also has its disadvantages: heavy workload and obvious environmental constraints. The detection is particularly consuming manpower, material and finan...
