Abstract
Systems, methods and apparatus are provided through which a 3D source mesh object is generated by a three-dimensional-augmented-reality engine from medical data, a copy mesh object is generated by copying the 3D source mesh object, a center of the 3D source mesh object is calculated from the 3D source mesh object, an orientation bar is generated and placed orthogonally in the center of the copy mesh object, a scene mesh object a generated by scanning the room, the scene mesh object being a game object, a patient mesh object is generated by cutting the scene mesh object in reference to original dimensions of the 3D source mesh object and a patient mesh object is generated from the patient mesh object by starting from the index tip of a finger and placing the 3D source mesh object in a direction that is downwards.
Core Innovation
The invention relates to generating a 3D source mesh object from medical data using a three-dimensional-augmented-reality engine. The medical data is selected from computed tomography scan data and magnetic resonance scan data, and the 3D source mesh object is encoded in byte format. A copy mesh object is generated by copying the 3D source mesh object, and a center of the 3D source mesh object is calculated from the 3D source mesh object. An orientation bar is generated and placed orthogonal to the surface of the copy mesh object at the center of the copy mesh object.
The invention further generates a scene mesh object by scanning the room, where the scene mesh object is a game object. A patient mesh object is generated by cutting the scene mesh object in reference to original dimensions of the 3D source mesh object. The cutting starts from a tip of a finger and places the 3D source mesh object in a direction that is downwards by half of a depth of the 3D source mesh object.
In additional aspects, the invention determines a new position of the patient mesh object in terms of x, y and z coordinates from a manually set reference point. The apparatus form discloses a microprocessor coupled to generators for the 3D source mesh object, center calculation, orientation bar, scene mesh object, patient mesh object, and a displayer that displays the patient mesh object including the orientation bar.
Claims Coverage
The document provides three independent claims with core coverage centered on generating and positioning meshes for augmented reality using a three-dimensional-augmented-reality engine, including an orthogonal orientation bar and cutting a room-scanned scene mesh to patient mesh dimensions.
Generate 3D source mesh and orthogonal orientation bar for AR
Generating a 3D source mesh object by a three-dimensional-augmented-reality engine from medical data, the 3D source mesh object being encoded in byte format; calculating a center of the 3D source mesh object; generating an orientation bar placed orthogonal to the surface of the copy mesh object at the center of the copy mesh object.
Cut room-scanned scene mesh to patient mesh dimensions using fingertip and half-depth direction
Generating a scene mesh object by scanning the room, the scene mesh object being a game object; generating a patient mesh object by cutting the scene mesh object in reference to original dimensions of the 3D source mesh object by starting from a tip of a finger and placing the 3D source mesh object in a direction that is downwards by half of a depth of the 3D source mesh object.
Determine patient mesh position with x, y, z and orthogonal orientation bar
Determining a new position of a patient mesh object in terms of x, y and z coordinates from a manually set reference point; generating an orientation bar placed orthogonal to a surface of a copy mesh object at a center of the copy mesh object; generating a scene mesh object by scanning the room; generating a patient mesh object by cutting the scene mesh object in reference to original dimensions of a 3D source mesh object.
AR apparatus generating source mesh, center, orthogonal orientation bar, patient mesh, and display
A microprocessor; a generator of a 3D source mesh object from two-dimensional or three-dimensional medical image data; a calculator of a center of the 3D source mesh object; a generator of an orientation bar placed orthogonal to the surface of the 3D source mesh object at a center of the 3D source mesh object; a generator of a scene mesh object; a generator of a patient mesh object that cuts the scene mesh object in reference to original dimensions of the 3D source mesh object; and a displayer of the patient mesh object including the orientation bar.
Across the independent claims, the inventive coverage is directed to augmented reality generation of meshes from medical image data, computing a center, generating an orthogonal orientation bar, generating a scene mesh by scanning the room, and generating a patient mesh by cutting the scene mesh in reference to original source-mesh dimensions. The apparatus claim frames these functions as microprocessor-coupled generators and a displayer for presenting the patient mesh object including the orientation bar.
