LASER PROJECTOR Russian patent published in 2012 - IPC H04N9/31 

FIELD: information technologies.

SUBSTANCE: laser projector relates to systems of image reproduction, and more specifically to video projection equipment, which may be used in the area of geodesic instrument making, in particular, in laser instruments for building planes designed for location survey in construction, in installation of technical equipment, and also in other fields of science and engineering, where it is required to use a light plane and to shift marks in horizontal and vertical planes. A laser projector comprises a projection element to display an image, which may represent both reproduction of anything and reproduction of scribe axes, a supply and control system. Besides, the laser projector comprises an electronic unit of projected image position correction related to a multiaxis sensor of projection element position, and an interface of image file downloading.

EFFECT: automatic correction of an image projection position correction due to installation of an electronic correction unit related to a multiaxis sensor of a projection element position.
