Tunnel three-dimensional modeling system and method based on depth camera lens

Abstract

The invention discloses a tunnel three-dimensional modeling system and method based on a depth camera lens. The system comprises a depth camera lens device and a rotary apparatus, the depth camera lens device comprises a microphone assembly, an infrared camera, a color camera and an infrared camera lens, the depth camera lens device is arranged on the rotary apparatus, the depth camera lens device is driven by the rotary apparatus to rotate 180 degrees in the vertical direction, and images of upper half circle of a tunnel are collected; an angle transducer is arranged on the rotary apparatus and used for detecting the rotation angle of the rotary apparatus, and at the same time, an elevation controller is arranged on the rotary apparatus and used for controlling the acquisition angle of the depth camera lens device. According to the tunnel three-dimensional modeling system and method based on the depth camera lens, through the analysis for tunnel relevant color information, overall terrain conditions such as joint and fissure in the tunnel can also be observed, and therefore more targeted scientific construction is carried out.

Description

technical field [0001] The invention relates to a tunnel three-dimensional modeling system and method based on a depth camera. Background technique [0002] As a country with rapid development in technology and economy, more tunnels and subways will inevitably be built in the process of urban construction to meet transportation needs. Of course, in order to avoid accidents, in order to better predict the situation of the tunnel and make the process of tunnel excavation go more smoothly, we use the depth camera to model the tunnel in 3D, so that the situation of the entire tunnel can be presented in 3D space Come out, let us have a more intuitive understanding of the tunnel information, so as to avoid some accidents. [0003] Currently, depth cameras have a wide range of applications. Its main reason for development is to be used in the very popular somatosensory games at present, so that users can have a better experience. However, with the continuous advancement of techn...

Problems solved by technology

[0005] To sum up, there are some known difficulties that need to be overcome in the tunnel scene imaging process. On the one hand, it takes a considerable amount of memory to reconstruct a large-scale scene, and the reconstruction process takes a considerable amount of time. On the other hand, It is not easy to extract the color information in the harsh environment of the tunnel. Due to the lack of hardware conditions and facilities, it is necessary to spend more energy in the process of color information processing in the later stage.

Moreover, the environment in the tunnel is relatively poor, and the frequent use of some sensitive equipment in the tunnel will inevitably reduce the service life, so it is necessary to add good protection measures
