Object three-dimensional model identification method, device and equipment and readable storage medium

Abstract

The invention relates to an object three-dimensional model identification method, device and equipment and a readable storage medium. The geometric feature information of the object three-dimensional model and the geometric feature information of the object entity included in the design drawing are subjected to overall recognition registration, and scanning errors and recognition errors can be mutually offset among different geometric features to a certain extent, so that the recognition result is more accurate, the teaching purpose can be achieved, and the teaching efficiency is improved. Related personnel are helped to better carry out space three-dimensional positioning judgment and operation, the learning time is shortened, the related personnel can be helped to carry out preoperative practice, the medical safety is improved, and the medical burden is relieved. Due to the fact that the second position information of the at least three optical markers on the object entity is tracked through the conversion relation and the optical tracking system, the pose of the object three-dimensional model can be adjusted in real time, and a doctor can be helped to complete preoperative planning and practice.

Description

technical field [0001] The present disclosure relates to the field of virtual reality, and in particular to a method, device, equipment and readable storage medium for recognizing a three-dimensional model of an object. Background technique [0002] Usually, clinical operation is an important means of diagnosis and treatment in modern medicine. In actual clinical practice, such as brain surgery, the success rate is low, the risk is high, and it requires superb surgical skills and rich clinical experience. When inexperienced doctors need surgical training, the existing technology usually stays at the stage where experienced doctors teach clinical experience to interns, or interns watch experienced doctors perform operations. [0003] However, the surgery is performed directly on the patient, so the surgical field of view is relatively limited, and it is even more impossible for the doctor to see through the patient's tissue structure. In addition, the shape of the lesion oft...

Problems solved by technology

[0003]However, the surgery is performed directly on the patient, so the surgical field of view is relatively limited, and it is even more impossible for the doctor to see through the patient's tissue structure, and the lesion often changes in shape during the operation , there are complex distortions in the vascular structure, which are often difficult to visually identify

The medical imaging equipment equipped in the operating room is complicated to use, and often requires specialized medical staff to operate the equipment, which is inconvenient to use. It is difficult for surgeons and interns to associate intraoperative findings with preoperative imaging images. This information asymmetry The situation makes it difficult to identify anatomical structures, which affects intraoperative decision-making, and also affects the training effect of interns
