Abstract
An object-tracking method and system are provided. A light beam is emitted by a light emitter of each of a plurality of assembly pads. A plurality of images toward the assembly pads are continuously captured by an image pickup apparatus, wherein each image includes a plurality of light regions formed by the light beams. A first image and a second image are analyzed to calculate a change of movement of the light regions, wherein the first image and the second image are two adjacent images. Thereafter, a motion state of the image pickup apparatus is determined based on the change of movement.
Claims20
An object-tracking method, comprising:
- emitting a light beam by a light emitter of each of a plurality of assembly pads, wherein the assembly pads are assembled to form a light emitting region;
- continuously capturing a plurality of images toward the assembly pads in the light emitting region by an image pickup apparatus, wherein each of the images comprises a plurality of light regions formed by the light beams;
- analyzing a first image and a second image to calculate a change of movement of the light regions, wherein the first image and the second image are adjacent images in the images;
- and
- determining a motion state of the image pickup apparatus based on the change of movement.
An object-tracking system, comprising:
- a plurality of assembly pads, assembled to form a light emitting region, wherein each of the assembly pads comprises a light emitter configured to emit a light beam;
- and
- an image pickup apparatus, comprising:
- an image capturer continuously capturing a plurality of images toward the assembly pads in the light emitting region, wherein each of the images comprises a plurality of light regions formed by the light beams;
- and
- an image analyzer, coupled to the image capturer, receiving the images, and analyzing the images, wherein the image analyzer analyzes a first image and a second image to calculate a change of movement of the light regions, the first image and the second image are adjacent images in the images, and the image analyzer determines a motion state of the image pickup apparatus based on the change of movement.
