Abstract
The present invention discloses an image capture device and depth information calculation method thereof. The depth information calculation method includes: acquiring, a stereo camera module, an image information; and determining a re-projection mode according to a usage scenario, and transforming the image information to a depth information corresponding to the re-projection mode according to the re-projection mode. The re-projection mode is planar mode, cylinder mode or spherical mode, and the corresponding coordinate systems are planar coordinate system, cylinder coordinate system and spherical coordinate system respectively.
Claims22
An image capture device, comprising:
- a stereo camera module, configured to acquire image information;
- and
- a processing unit, coupled to the stereo camera module, and configured to determine a re-projection mode according to an operation scenario, and transform the image information to depth information corresponding to the re-projection mode according to the re-projection mode;
- wherein a first image and a second image are acquired by the stereo camera module, a third image is generated by the processing unit according to the first image and the second image, and the third image is projected by the processing unit to a display coordinate system corresponding to a re-projection mode according to the re-projection mode to generate a fourth image, and wherein when the re-projection mode changes, the display coordinate system changes accordingly.
