Portable binocular photogrammetry device

Abstract

The invention provides a portable binocular photogrammetry device, and belongs to the technical field of rock mass measurement. The portable binocular photogrammetry device comprises a support assembly and a balance assembly. The supporting assembly comprises a supporting table, supporting rods, a middle column rod and pull rods, and the balance assembly comprises a fixing table, fixing guide rods, balance belts, balance seats, balance motors, a balance table and balance rods. The multiple balance motors independently control the height and the rotation angle of the balance rods, so that the level of the photogrammetry device is accurately adjusted, and the rock photography precision is improved; compared with manual photography data acquisition, by multi-point telescopic supporting, the field fixing and supporting of the photography device are facilitated, and the stability precision of photography of the photography device is improved; and through the automatic balance design, the height and rotation angle of lifting sliding rods are adjusted in a multi-point supporting manner, so that a photographing device base is automatically adjusted to be horizontal while the supporting stability is improved, the stability precision of photographing of the photographing device is improved, and the precision and stability of rock measurement photographing are higher.

Description

technical field [0001] The present application relates to the technical field of rock mass surveying, in particular to a portable binocular photogrammetry device. Background technique [0002] A field observation and monitoring method with the function of "rock mass measurement" in the related technology. Usually, rock mass structural surface data needs to be collected, extracted, and analyzed in the investigation of rock mass stability and permeability. The traditional method of manual measurement and data collection requires on-site monitoring of the rock mass, manual photogrammetry data collection on the rock surface, and then two-dimensional imaging of the collected photogrammetry data to facilitate comparison and analysis of the rock mass. [0003] However, due to geographical space reasons, it is difficult for artificial rock mass measurement to work in strong deformation dangerous areas, tunnels, and small deformation areas, resulting in difficulties in rock mass data...

Problems solved by technology

[0003] However, due to geographical space reasons, it is difficult for artificial rock mass measurement to work in strong deformation dangerous areas, tunnels, and small deformation areas, resulting in difficulties in rock mass data collection, insufficient imaging accuracy of rock mass structures, and large errors in manual photogrammetry, which further cause rock mass Insufficient accuracy of body structure imaging
