Training method of sketch sequence reconstruction model, geometric model reconstruction method and equipment

The invention discloses a sketch sequence reconstruction model training method, a geometric model reconstruction method and equipment. The training method comprises the following steps: acquiring a training data set; inputting training point cloud data in the training data set into a preset network model, and determining predicted sketch sequence parameters and predicted point cloud boundaries through the preset network model; and determining a target loss item based on the predicted sketch sequence parameter, the predicted point cloud boundary, the labeled sketch sequence parameter and the labeled point cloud boundary, and optimizing the preset network model based on the target loss item to obtain a sketch sequence reconstruction model. According to the method, the point cloud segmentation task and the sketch sequence prediction task are combined, so that the extraction of deep point cloud information by the network is remarkably improved, the parameter prediction precision is improved, the problems that the
