Abstract: A system for registering position and orientation (P&O) of mobile devices relative to a construction site may include: a light projector; at least one sensor configured to record at least one set of XYZ coordinates of at least one specific surface, and a set of XYZ coordinates of the light projector within the construction site; and a computer processor, wherein the light projector is configured to project the XYZ coordinates of the at least one set of position markers onto the at least one specific surface; and wherein the projection of the XYZ coordinates of the at least one set of position markers is detectable by at least one sensor located at a mobile device, allowing registration of XYZ coordinates of a virtual reality interface of the mobile device relative to the projection of the position markers onto the at least one specific surface.

Abstract: A method and a system for projecting a construction plan or a specified pattern in a construction site. The system may include: a light projector configured to project an image associated with the construction plan or the specified pattern, onto a specific surface within the construction site; at least one sensor configured to obtain dimensional parameters of at least one of: the specific surface, and the image as projected on the specific surface; and a computer processor configured to: derive, from the construction plan or the construction pattern, an intended projection portion which comprises visual content intended to be projected on the specific surface; calculate a model of said image, based on the dimensional parameters obtained from the at least one sensor; and generate a modified projection portion based on the model, and the intended projection portion, wherein the light projector is further configured to project said modified projection portion.

Abstract: A method and a system for projecting an adaptive augmented reality content over a dynamically changing construction site are provided herein. The system may include: a capturing device comprising at least one sensor configured to capture 3D images of a scene; a computer processor configured to: generate a 3D model of surfaces within said scene, based on said captured 3D images; and obtain a construction plan associated with a construction to be built in said scene; generate projectable visual content based on a desired state of construction based on the construction plan and a current state of the construction based on said 3D model of surfaces within said scene; and a projector configured to project said projectable visual content onto said surfaces within said scene, wherein said capturing device, said computer processor, and said projector are configured to repeat their operation and update said projectable visual content.
