Abstract
A preferred system and method for displaying a set of indicator coordinates in relation to a building information model includes a system administrator, a registration base and a headset unit. The system includes a headset including a display and a registration base for initial placement of the headset. The headset further includes a set of stereo cameras. The cameras capture an image of the construction site and overlay an image which includes the indicator coordinates. A position of the headset is determined relative to the registration base from motion sensors. A set of indicator coordinates is downloaded and projected to the display based on the position and orientation of the headset.
Claims20
A system for displaying a set of indicator coordinates from a building information model comprising:
- a headset having a first processor connected to a first memory;
- a camera, operatively connected to the first processor, producing a camera signal;
- a display screen, supported by the headset, and operatively connected to the first processor;
- the headset having a first position associated with the building information model and a second position disassociated from the building information model;
- the first memory having a set of instructions that when executed cause the first processor to:
- construct an overlay image from the set of indicator coordinates and the camera signal;
- determine a difference between the first position and the second position;
- generate a set of position data based on the difference;
- calculate a set of translation threshold values;
- calculate a set of rotation threshold values;
- compute an overlay layer from the overlay image;
- calculate a display overlay layer based on the set of position data and the overlay layer;
- construct a display image from the display overlay layer and the camera signal;
- and,
- project the display image on the display screen.
A method of displaying indicator coordinates from a building information model comprising:
- providing a headset having a first processor connected to a first memory;
- providing a camera operatively connected to the first processor;
- providing a camera signal from the camera;
- providing a display screen, supported by the headset, and operatively connected to the first processor;
- providing a first position of the headset related to the building information model and a second position of the headset unrelated to the building information model;
- providing a set of instructions, resident in the first memory, that when executed, cause the first processor to:
- construct an overlay image from the set of indicator coordinates and the camera signal;
- determine a difference between the first position and the second position;
- generate a set of position data based on the difference;
- calculate a set of translation threshold values;
- calculate a set of rotation threshold values;
- compute an overlay layer from the overlay image;
- calculate a display overlay layer based on the set of position data and the overlay layer;
- construct a display image from the display overlay layer and the camera signal;
- and,
- project the display image on the display screen.
