Abstract
A method for overlapping images is revealed. After overlapping the overlapped regions in two depth images generated by structured-light camera units, a first image, the overlapped image, and a fourth image are display on a display unit. Thereby, the drivers' viewing ranges blocked by the vehicle body while viewing outwards from the interior of a vehicle can be retrieved. Then the drivers' blind spots can be minimized and thus improving driving safety.
Claims7
A method for overlapping images, comprising steps of:
- generating a first depth image using a first structured-light camera unit and generating a second depth image using a second structured-light camera unit, said first depth image including a first image and a second image, and said second depth image including a third image and a fourth image;
- acquiring a plurality of first stable extremal regions of said second image and a plurality of second stable extremal regions of said third image according to a first algorithm;
- and
- overlapping said second image and said third image to generate a first overlapped image, and displaying said first image, said first overlapped image and said fourth image on a display unit when said plurality of first stable extremal regions and said plurality of second stable extremal regions match.
