Abstract
A projection device includes a projection module and a first camera module. The projection device has a first optical axis and configured to form a projection area, wherein a projection of the first optical axis on an X-Z plane of the projection device is perpendicular to an X-Y plane on which the projection area is formed. The first camera module is disposed on a side of the projection module and includes a second optical axis, wherein the first camera module is configured to form a first shooting area, the second optical axis forms a first angle Δθwith respect to the first optical axis, the projection area at least partially overlaps the first shooting area to form an overlapping area, and the first angle Δθis a function of a distance between the projection module and the first camera module.
