摘要
A projector for acquiring a coordinate of a bright spot includes a half transparent and half reflecting mirror (22), an imaging device (24), and a processing system (25). The half transparent and half reflecting mirror (22) is provided on a light path between the light source (21) and the zooming system (23). The imaging device (24) captures an external light ray reflected by the half transparent and half reflecting mirror (22). The processing system (25) acquires the coordinate of the bright spot according to the image of the image of the bright spot captured by the imaging device.
