Projection device for displaying construction plans

A projection device for displaying construction plans, the projection device comprising:

• a projector head comprising:
• a set of projection optics,
• a laser module,
• a galvanometric system adapted to direct incident light from the laser module toward the set of projection optics,
• a yaw encoder adapted to detect in real-time a yaw of the projector head, and
• a pitch encoder adapted to detect in real-time a pitch of the projector head;
• a memory device adapted for storing one or more construction plans;
• and
• a controller operatively connected to the laser module, the galvanometric system, the yaw encoder, the pitch encoder, and the memory device, the controller being adapted for:
• choosing a construction plan to be displayed from the memory device,
• selectively activating the laser module, and
• selectively causing the galvanometric system to follow a path defined by the chosen construction plan concurrently with the selective activation of the laser module so that the incident light directed toward the projection optics selectively forms a projection of the construction plan on a construction site, the projection of the construction plan being adapted in real-time according to changes in the yaw, the pitch, or both the yaw and the pitch of the projector head.

• a galvanometric system adapted to direct incident light from the laser module toward the set of projection optics;
• a memory device adapted for storing one or more construction plans;
• a controller operatively connected to the laser module, the two mirror galvanometers, and the memory device, the controller being adapted for:
• choosing a construction plan to be displayed from the memory device, selectively activating the laser module, and
• selectively causing the first and second minor galvanometers to follow a path defined by the chosen construction plan concurrently with the selective activation of the laser module so that the incident light redirected toward the projection optics selectively forms a projection of the construction plan on a construction site;
• and
• a laser safety module operatively connected to the laser module, the laser safety module being adapted for dynamically controlling an operation of the laser module.
