IMAGE CAPTURE ENHANCEMENT USING DYNAMIC CONTROL IMAGE

摘要

Embodiments of the present invention provide systems and methods for image capture with infrared emitters, with associated computer control and processing for providing consistent and high quality image data. Image data of consecutive frames from a camera is obtained, with a first frame being taken during an emission of infrared light directed at a scene to be captured by the camera and a second frame being taken without an emission of infrared light. The consecutive frames provide a dynamic control image of the captured scene. The image data may be used to support photometric sampling techniques used in building geometric models for subject recognition in camera imagery in variable lighting environments.

主权项

1. A computer-implemented method for image capture enhancement, comprising:
activating a sequence of infrared emissions, by one or more emitters in an environment space monitored by a camera for capturing images of the environment space, wherein the sequence of infrared emissions is synchronized with a frame counter of the camera; receiving captured image frames from the camera, wherein the captured image frames comprise a first frame captured during an emission, and a second frame, adjacent to the first frame, captured outside the emission; subtracting the second frame from the first frame to provide an image of a reflected infrared component; removing, from the reflected infrared component, a previously obtained background image of the environment space to enhance a subject in the image; and outputting a resultant image for processing.
