Image stabilization system for handheld devices equipped with pico-projector

摘要

It is proposed a method for the projection of a sequence of images onto a projection surface by a handheld device having an embedded projector, said method comprising, for an input image (1A) to be projected of said sequence of images:
—� a step of evaluation (23) wherein a spatial position variation (233) is evaluated with respect to a reference spatial position 231) of said handheld device ; and said spatial position variation (233) is defined by a spatial orientation variation and a spatial vector variation; said spatial vector variation (233) being determined by 3 independent coordinates; and at least one of said 3 independent coordinates is provided by a stereoscopic sensor
—� a step of compensation (24) wherein a compensated image (1B) is generated from said input image (1A) to be projected depending on said spatial position variation (233); and
—� a step of projecting onto said projection surface said compensated image (1B)
