Description

Technical field [0001] The invention belongs to the technical field of three-dimensional reconstruction, and specifically relates to a portable three-dimensional scanning device based on a 2D laser radar. Background technique [0002] Three-dimensional reconstruction technology can realistically establish the virtual information space of the objective world in the computer, and generate valuable three-dimensional shape information. Through the analysis, mining, retrieval and efficient use of these three-dimensional shape information, it can meet the needs of many major applications such as digital factories, digital cities, digital mines, cultural relics reconstruction, and disaster warning. The current mainstream 3D reconstruction technologies are mainly divided into two categories according to different hardware usage. One is to use a digital camera to shoot images from multiple perspectives for three-dimensional reconstruction. This reconstruction technology first needs to c...
