Abstract
A method for performing hybrid depth detection with aid of an adaptive projector and associated apparatus are provided. The method includes: utilizing an image processing circuit to obtain distance information; utilizing the image processing circuit to determine a distance range according to the distance information; utilizing the image processing circuit to perform projection type selection to determine at least one selected projection type corresponding to the distance range among multiple predetermined projection types; utilizing the adaptive projector to perform projection of the at least one selected projection type to capture at least one corresponding image with a camera, and utilizing the image processing circuit to perform depth detection according to corresponding image to generate depth map; and utilizing the image processing circuit to selectively output the depth map as resultant depth map or perform depth data combination to generate combined depth map as resultant depth map.
