AN IMAGING SYSTEM AND METHOD FOR ESTIMATING THREE-DIMENSIONAL SHAPE AND/ OR BEHAVIOUR OF A SUBJECT

摘要

Disclosed is an imaging system for estimating three-dimensional shape and/or behaviour of a subject, comprising a container to receive the subject; and an image capture device optically coupled to the container and to capture a two- dimensional image of the subject, the captured image comprising a plurality of micro-images, each micro-image representing a separate portion of a two-dimensional representation of a three-dimensional light-field in the container and including depth information of the subject in the container, wherein the three-dimensional shape and/or behaviour of the subject is estimated based on the captured two-dimensional image of the subject. The image capture device is preferably a plenoptic depth camera (also known as a light field camera), and may be used to track the movement of a living organism in a tank, such as a zebrafish. The geometry of the container is preferably configured to compliment the field of view of the optics of the image capture device, e.g. in the shape of a pyramid.
