Abstract
Hardware and software methodology are described for three-dimensional imaging in connection with a single sensor. A plurality of images is captured at different degrees of focus without focus change of an objective lens between such images. Depth information is extracted by comparing image blur between the images captured on the single sensor.
Claims16
A three-dimensional imaging system comprising:
- a single image sensor,
- optics adapted to allow the single sensor to capture images from substantially the same viewpoint that are focused to blur in different degrees without a change of objective lens focus, and
- a computer processor connected with the sensor, wherein the processor is adapted to match elements from the images and determine depth position for elements of the images by comparing differences in blurring for the elements.
A method of three-dimensional imaging comprising:
- capturing, with a single sensor, a plurality of images of an object with a camera from substantially the same viewpoint at different focuses without moving a camera objective lens;
- and
- using a computer processor, matching elements from the images and determining depth position for the elements of the images by comparing differences in size for the elements.
