Object identification method and object identification device

An object identification method comprising:

• capturing color images and depth images that are aligned;
• acquiring a start frame and an end frame in the captured color image and depth images;
• comparing the end frame with the start frame in the color images to acquire a set of motion pixels;
• performing connected component analysis on the acquired set of motion pixels to obtain at least one connected component;
• dividing the at least one connected component into at least one object component based on depth information of the end frame in the depth image;
• and
• identifying an object in the at least one object component.

An object identification device comprising:

• a capturing member, configured to capture color images and depth images that are aligned;
• a detecting member, configured to perform motion detection on the captured color images and the depth images to acquire a motion start frame and a motion end frame;
• an acquiring member, configured to compare the motion end frame with the motion start frame in the color images to acquire a set of motion pixels;
• an analyzing member, configured to perform connected component analysis on the acquired set of motion pixels to obtain at least one connected component;
• a dividing member, configured to divide the at least one connected component into at least one object component based on depth information of the motion end frame in the depth images;
• and
• an identifying member, configured to identify an object in the at least one object component.
