Abstract
Simulation systems and methods may enable virtual imaging. A data processing unit may receive data from a calibration unit indicating a position and/or orientation of a position and orientation sensor relative to a physical model. The data processing unit may also receive data from the position and orientation sensor indicating a position and/or orientation of the physical model. The data processing unit may generate a virtual image using the data from the position and orientation sensor and the data from the calibration unit. The data processing unit may render the virtual image to a display.
Core Innovation
The invention provides a multipurpose medical simulation system that uses a physical model comprising an anatomy model, a tool, a position and orientation sensor, and a calibration unit. The calibration unit stores calibration data associated with the position and orientation sensor and the physical model, and the data processing unit uses this calibration data to identify the physical model.
After identification, the data processing unit proposes a choice of simulation scenarios, where each simulation scenario comprises a virtual reality (VR) model or an augmented reality (AR) model. The system receives a user selection of one simulation scenario, receives position/orientation sensor data indicating the position and orientation of the physical model, and uses both the sensor data and the stored calibration data to generate the corresponding VR model or AR model.
The generated VR model or AR model is rendered to a display, and the invention supports tool and scenario handling associated with the physical model. The document further describes tracking and calibration using sensor transmitter units and calibration identifiers, and it includes mechanisms for presenting scenario choices and for generating interaction content using precomputed image libraries and interpolation.
Claims Coverage
The document provides two independent claims: an independent simulation system claim and an independent simulation method claim. Both claims share the same core pipeline: calibration-based identification, scenario proposal/selection, generation of a VR or AR model, and rendering to a display, using position and orientation sensor data combined with stored calibration data.
Calibration-based identification and scenario proposal for VR/AR
Identify the physical model based on the calibration data and propose a choice of simulation scenarios based on the identification, each simulation scenario comprising a virtual reality (VR) model or an augmented reality (AR) model.
Sensor-based generation of VR/AR model using calibration offsets
Generate the VR model or AR model associated with the selected simulation scenario using the data from the position and orientation sensor and the calibration data from the calibration unit.
Rendering the generated VR/AR model to a display
Render the VR model or AR model to the display.
Across both independent claims, the inventive coverage centers on using calibration data to identify the physical model and propose scenario options, generating a VR or AR model from real-time position and orientation sensor data combined with the stored calibration data for the selected scenario, and rendering the generated VR/AR model to a display.
