Research on plant three-dimensional information acquisition method

Plant three-dimensional information acquisition technology can accurately reproduce the morphology of specific plants, and can be used to study the spatial structure related properties of plants. The paper mainly studied how to obtain complete plant point cloud data by using a three-dimensional data acquisition system and rotating device, and then to obtain the three-dimensional information of plant spatial entities quickly and non-destructively. A rectification technology was proposed based on external additional structure, which partly solved the problem that the point cloud cannot be registered well. The results can provide a reference for the modeling technology of the virtual plants growth.
