Abstract
This application describes techniques for correcting distortion in projected images. In some instances, a projection device may project an image onto a projection surface within an environment. However, the projected image may initially distorted from the perspective of a user within the environment due to the angle of the projection onto the surface and due to the location of the user relative to the projection. To help correct this distortion from the vantage point of the user, the user utilizes a mobile device to capture an image of the projection. This image is then used to calculate one or more calibration parameters for execution by the projection device to remove the distortion of the image as projected from the perspective of the user.
