Method for embedding digital information in a three dimensional image from a scannerless range imaging system
摘要:
A scannerless range imaging system employs a technique for embedding digital data into its image output in a manner that allows exact recovery of its associated images. The range imaging system captures (a) a plurality of phase images of reflected modulated illumination, wherein each image incorporates a phase delay term corresponding to the distance of objects in the scene from the range imaging system, together with a phase offset term unique for each image, and (b) at least one intensity image of reflected unmodulated illumination, and then generates an image bundle of associated images including the plurality of phase images and the intensity image. Meta-data is embedded into the image bundle by a) forming a digital message from the meta-data, b) converting the digital message to embedded data, and c) adding the embedded data to each phase image in the image bundle, pixel by pixel, without changing the phase term in each of the phase images, thereby allowing exact reconstruction of range information from the phase images without having to extract the embedded data.
