Data acquisition device for three-dimensional rapid reconstruction of industrial field traffic scene

Abstract

The invention discloses a data acquisition device for three-dimensional rapid reconstruction of an industrial field traffic scene. The data acquisition device comprises a data acquisition assembly; a square pipe is vertically arranged on the vertical inner wall of the industrial field; a power device is arranged on the inner wall of the square pipe, and a first chain wheel is arranged on a first rotating shaft; a second chain wheel is arranged on a second rotating shaft and is in transmission connection with the first chain wheel through a chain, and the chain is connected with a first sliding plate; the first sliding plate is arranged at the front end of the square pipe, a rotating ball is arranged on the first sliding plate, a second supporting plate is arranged on the rotating ball, and a camera is arranged on the second supporting plate; a first gear is arranged on the side surface of the second supporting plate; a second gear is meshed with the first gear; a first worm is meshed with a first worm wheel; and an angle adjusting assembly is arranged on the square pipe. According to the invention, an operator does not need to hold a camera for shooting, time and labor are saved, three-dimensional reconstruction can be carried out without going to the site, the shooting height consistency of each camera is simple and convenient to control, and the improvement of the accuracy of three-dimensional reconstruction of an industrial site is facilitated.

Description

technical field [0001] The invention relates to the technical field of data acquisition, in particular to a data acquisition device for rapid three-dimensional reconstruction of traffic scenes in industrial sites. Background technique [0002] The establishment of a 3D navigation system is an important part of enterprise informatization, and the measurement, collection and production of 3D model data of industrial sites is a part of the entire 3D navigation system construction process and the basis for the development and operation of the 3D navigation system. However, the traditional manual method has the following problems when collecting data: low efficiency, time-consuming and laborious; low precision, difficult to meet the needs of production management; difficult data management and organization; poor data compatibility, resulting in low data utilization. With the development of aviation, aerospace technology and computer digital image processing technology, the cost o...

However, the traditional manual method has the following problems when collecting data: low efficiency, time-consuming and laborious; low precision, difficult to meet the needs of production management; difficult data management and organization; poor data compatibility, resulting in low data utilization

With the development of aviation, aerospace technology and computer digital image processing technology, the cost of photogrammetry equipment has been greatly reduced. Digital photogrammetry has become the main means of large-scale and large-area measurement. After relevant data processing, it can provide rich geospatial information. The data in this way is the on-site photos of the industrial site. A large amount of photo data is required for the rapid three-dimensional reconstruction using photo data. There are two ways to collect photo data. One is to take multiple images of objects on the rotating platform, but The industrial site is fixed, so the second method can only be used, that is, to rotate the camera for multi-angle shooting, and it is best to take two sets of photos at different heights from the same angle, which is convenient for post-processing by the computer. The existing photo data The acquisition device requires the operator to hold the camera to shoot, which is inconvenient to use and requires personnel to operate on site. The 3D rapid reconstruction is slow, and the consistency of the shooting height is inconvenient to control, which has a certain impact on the results of the 3D reconstruction.
