Corn ear three-dimensional reconstruction device and method based on neural radiation field

The invention discloses a corn ear three-dimensional reconstruction device and method based on a nerve radiation field. The device comprises a host control end, a control panel, a steering engine, a rotary holder, an angle sensor, a camera, a display module, a fixed chassis, a background plate and a tripod. The method comprises the steps that a host control end and a camera are used for shooting a group of multi-frame image sequences surrounded by corn ears by 0-360 degrees, and the multi-frame image sequences serve as training sample data of a subsequent model; making a corn ear data set and carrying out data preprocessing to recover a camera pose; performing three-dimensional reconstruction by using a neural radiation field network to obtain corn ear point cloud information; and calculating phenotypic parameters of the corn ears. According to the method, multi-angle collection can be performed on the corn ears, three-dimensional reconstruction can be accurately realized, phenotype information can be acquire
