A portable binocular photogrammetry device

Abstract

The application provides a portable binocular photogrammetry device, which belongs to the technical field of rock mass measurement. The portable binocular photogrammetry device includes a support component and a balance component. The support assembly includes a support platform, a support rod, a central column rod and a pull rod, and the balance assembly includes a fixed platform, a fixed guide rod, a balance belt, a balance base, a balance motor, a balance platform and a balance bar. Multiple balance motors independently control the height and rotation angle of the balance pole, precisely adjust the level of the photogrammetry device, and improve the accuracy of rock photography. The stable accuracy of shooting, automatic balance design, multi-point support lifting slide bar height and rotation angle adjustment, while increasing the support stability, automatically adjust the level of the base of the photographic device, improve the stable accuracy of the photographic device, and the accuracy of rock survey photography and Greater stability.

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
