Abstract:
1. An object contour detection device, comprising: a lens, having a shallow depth of field; an image sensor, corresponding to said lens; and a microprocessor, electrically connected to said image sensor; wherein, said image sensor respectively senses a plurality of images of an object when said lens is moved at a plurality of positions repeatedly; said microprocessor detects and records said plurality of positions at which said lens is moved around repeatedly and said plurality of images having a one-to-one correspondence to said plurality of positions sensed by said image sensor; said microprocessor respectively removes unclear areas in said plurality of images to obtain a plurality of clear images, obtains a plurality of displacement quantities of depth of field depending on a displacement quantity between each two adjacent positions in said plurality of positions, allowing two adjacent front image and rear image in said plurality of clear images to correspond to a displacement quantity of depth of field: said microprocessor extends a depth of said front image to said corresponding displacement quantity of depth of field, and then combines said front image with said rear image in sequence, allowing said plurality of clear images to be combined into a stereoscopic image corresponding to said object contour.
