Tunnel oblique photography device

Abstract

The invention discloses a tunnel oblique photography device comprising: a tripod, a central bearing frame, a digital camera, a three-axis electronic cradle head, a cradle head control module, a camerasynchronization controller and a power module, wherein the central bearing frame is mounted on the tripod, the digital camera, the three-axis electronic cradle head, the camera synchronization controller and the power module are all integrated on the central bearing frame, an attitude line of the three-axis electronic cradle head and a video line of the digital camera are both connected with thecradle head control module, a shutter release of the digital camera is connected with the camera synchronization controller, the camera synchronization controller controls multiple digital cameras tosimultaneously expose, the cradle head control module controls the rotation angle of the three-axis electronic cradle head, and the power module and the three-axis electronic cradle head are electrically connected with the camera synchronization controller. The tunnel oblique photography device provided by the invention improves the collection working efficiency of tunnel digital images and ensures the quality of the digital images.

Description

technical field [0001] The invention relates to the field of geological survey, in particular to an oblique photography device for tunnels. Background technique [0002] Digital photogrammetry is based on the basic principle of digital imagery and photogrammetry, combined with the development of computer technology, digital image processing, image matching, pattern recognition and other disciplines. It realizes the geometric and physical information of photographic objects expressed digitally. . Based on the rapid development of digital photogrammetry technology, applied computer technology, and digital image processing, 3D image technology was born and widely used in the geological survey industry, and the ability to quickly acquire surface data (spatial information, object image texture) has been significantly improved. With the rapid development of my country's infrastructure construction level, the type and scale of underground buildings are increasing, and digital phot...

Problems solved by technology

Due to the relatively small cross-section of small-section and medium-section tunnels, the combination of straight and curved structures is more complex, and manual collection of digital images has difficulties in on-site operations, cumbersome work procedures, heavy workload, image quality is easily affected by the level of collection personnel, and collection efficiency is low. , special parts cannot be collected, and the quality of the three-dimensional image synthesized in the later stage is poor. It is difficult to promote and cannot effectively promote the development and improvement of geological survey technology.
