Abstract: A projection system (400) capable of projection alignment includes a projector (410), a shaped projection screen (420), one or more alignment marks (425), an image sensor (430), and a processing unit (440). The projector is configured to project an image. The shaped projection screen is configured to receive the projected image and display the projected image, the projector having a projection area (415) on the shaped projection screen. The one or more alignment marks are proximate to a border of the projection screen. The image sensor is configured to capture an image of the shaped projection screen and generate a sensor signal corresponding to the captured image. The processing unit is electronically coupled to the image sensor and configured to receive the sensor signal and determine the positions of the one or more alignment marks based on the sensor signal.
