INTERACTIVE POINTER DETECTION WITH IMAGE FRAME PROCESSING

摘要

An interactive input system comprises at least two imaging assemblies capturing image frames of a region of interest from different vantages, each imaging assembly comprising an image sensor and signal processing circuitry implemented on an application specific integrated circuit (ASIC), image data acquired by the image sensor being pre-processed by the signal processing circuitry; and processing structure processing pre-processed image data output by the imaging assemblies to determine the location of at least one pointer within the region of interest.
