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 tu

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033]Due to the large scale of the scene, the real-time processing method consumes a lot of GPU memory, so we use the method of offline data processing, that is, first collect all the information in the tunnel, and then process the data on this basis, thus avoiding memory Insufficient situation. Among them, the offline processing is also divided into two modes. One is to build a small-scale model first, and then splicing all the small-scale scene models one by one. Analytical processing to calculate the final 3D model. We use the latter method, because for the splicing model, there must be some errors, which is much worse than the accuracy of the latter. The depth camera reconstructs a single-frame smooth surface model of an object by fusing depth image data acquired from multiple angles. As the sensor moves, the camera's position and pose informati...

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...
