Embodiment 1

[0038] See Figure 1 to Figure 4 , a holographic perspective positioning system, including a planning module 1, a registration module, a positioning module 6, a tracking module 5, and a control module 7, and the planning module 1, registration module, and positioning module 6 are connected to the control module 7.

[0039] Based on the target entity 8, the planning module 1 generates a data package by reconstructing the 3D model of the target entity 8, and presetting the structure of the 3D model and several model positioning points for deep fusion in the positioning process. In this embodiment, it is used for intraoperative positioning in femoral surgery, and the target entity is the femur. The three-dimensional model of the affected part of the femur is reconstructed through the patient's medical image data, and the operation planning is performed to determine the angle and thickness of the osteotomy, as well as the positioning process. Deeply fused anatomical landmarks (ie,...

Embodiment 2

[0069] In this embodiment, it is used for intraoperative positioning in femoral surgery. The target entity is the femur. The composition and positioning method of the positioning system are basically the same as those in Embodiment 1. The difference is that in the calibration module used, the number of feature images is 4, and arranged in a straight line. There are 5 photosensitive spheres in the photosensitive module, and the photosensitive spheres are on the same plane and the area of ​​the pattern is not less than 60cm 2 .

Embodiment 3

[0071] A holographic perspective positioning system includes a planning module 1 , a registration module, a positioning module 6 , a tracking module 5 and a control module 7 , and the planning module 1 , registration module and positioning module 6 are connected to the control module 7 .

[0072] Based on the target entity 8, the planning module 1 generates a data package by reconstructing the 3D model of the target entity 8, and preset the structure of the 3D model and a number of model positioning points for deep fusion in the positioning process. In this embodiment, it is used for equipment maintenance guidance, and the target entity is the equipment to be maintained. Through the realization of the collected data, the 3D model of the equipment is reconstructed, and the planning is carried out to determine the structure of the place to be maintained in the equipment, and the deep fusion in the positioning. The mark point (namely the anchor point of the model) generates a data...

Abstract

The invention provides a holographic perspective positioning system. The system comprises a planning module, a registration module, a positioning module and the like, wherein a three-dimensional modelof a target entity is reconstructed through the planning module, a transfer matrix of position information between a mixed reality module and an optical positioning module can be obtained through theregistration module, and precision positioning of the target entity and the three-dimensional model can be finally realized. The invention further provides a positioning method, which comprises the steps of planning, advance preparation, information loading, registration, tracking and positioning to improve the positioning precision, deep fusion of the target entity and the three-dimensional model in a mixed reality module can be achieved, and intelligent application in different types of application scenes can be achieved. For instance, when the positioning system is used in the medical field, the three-dimensional model of an affected part is reconstructed through medical image data of the patient, the positioning precision between the virtual three-dimensional model and the affected part can be further improved, three-dimensional information is provided for doctors, the whole process is visualized, and accurate guidance is provided for the doctors in an operation.
