Abstract

The invention discloses an aero near view photography displacement measuring system based on a drone and a method of the system, and relates to an aero near view photography displacement measuring technology. The system comprises a drone (1), a digital camera (2), a ground control station (3), a microwave transmitter (4), a microwave receiving antenna (5), a data cable (6) and computer software (7); the drone (1) is provided with the digital camera (2) and the microwave transmitter (4) which are connected by a fly control board (1.1)of the mini model drone (1); the data cable connects a computer serial port (3.3) of the ground control station (3) and the microwave receiving antenna (5); the computer software (7) is installed in a notebook (3.1) of the ground control station (3). The invention can prevent some problems of traditional displacement measurement, and thus is applicable to displacement measurement to large displacement and large scale projects, in particular to displacementmeasurement to projects with difficult passage and in dangerous areas.

Description

technical field [0001] The present invention relates to an aerial close-range photographic displacement measurement technology, in particular to an aerial close-range photographic displacement measurement system and method based on an unmanned aerial vehicle (miniature model unmanned aerial vehicle); Non-contact measurement technology for large displacement engineering. Background technique [0002] Displacement measurement is an important means for safety evaluation, construction control and effect inspection of geotechnical engineering. In places with difficult access or dangerous operations, such as high and steep slopes, mine subsidence areas, and areas where debris flows occur, most existing displacement measurement technologies are time-consuming and labor-intensive, or even impossible to implement. Although technologies such as satellite remote sensing and aerial photogrammetry are not limited by site conditions, their measurement accuracy is low, and the latter is a...
