Abstract
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, the method including, for an input image to be projected of the sequence of images:
- a step of evaluation wherein a spatial position variation is evaluated with respect to a reference spatial position of the handheld device, and the spatial position variation is defined by a spatial orientation variation and a spatial vector variation, the spatial vector variation being determined by 3 independent coordinates, and at least one of the 3 independent coordinates is provided by a stereoscopic sensor;a step of compensation wherein a compensated image is generated from the input image to be projected depending on the spatial position variation; anda step of projecting onto the projection surface the compensated image.
