Abstract
Methods and systems for identifying depth data associated with an object are disclosed. The method includes capturing, with an image capturing device, a plurality of source images of the object. The image capturing device has a sensor that is tilted at a known angle with respect to an object plane of the object such that the image capturing device has a depth of field associated with each source image, the depth of field defining a plane that is angled with respect to the object plane. An image processor analyzes the plurality of source images to identify segments of the source images that satisfy an image quality metric. Position data is assigned to the identified segments of the source images, the position data including depth positions based on the plane defined by the depth of field.
