Abstract
A method and a system for determining a datum plane are disclosed. The method for determining a datum plane includes: acquiring a depth image; performing edge extraction on the depth image to form an edge image, the edge image including a plurality of planar graphs; and selecting from the planar graphs in the edge image to determine the datum plane. The technical solutions provided by the disclosure can easily match the virtual object with the real scene in real time, and improve users' sensory experience beyond reality.
Claims8
A method for determining a datum plane, comprising:
- acquiring a depth image;
- performing edge extraction on the depth image to form an edge image, the edge image comprising a plurality of planar graphs;
- and
- selecting from the planar graphs in the edge image to determine the datum plane,
- wherein the step of performing edge extraction on the depth image to form an edge image comprises:
- obtaining a gradient change rate of the depth image according to a preset gradient algorithm;
- forming a binary image according to the gradient change rate;
- and
- performing edge extraction on the binary image to form the edge image.
