Abstract:
An active-pulsed four-dimensional camera system that utilizes a precisely-controlled light source produces spatial information and human-viewed or computer-analyzed images. The acquisition of four-dimensional optical information is performed at a sufficient rate to provide accurate image and spatial information for in-motion applications where the camera is in motion and/or objects being imaged, detected and classified are in motion. Embodiments allow for the reduction or removal of image-blocking conditions like fog, snow, rain, sleet, and dust from the processed images. Embodiments provide for operation in daytime or nighttime conditions and can be utilized for day or night full-motion video capture with features like shadow removal. Multi-angle image analysis is taught as a method for classifying and identifying objects and surface features based on their optical reflective characteristics.

Claim (Index 29):
An active camera system configured to generate an image of a scene through a signal-attenuating environment comprising:\n at least one emitter configured to emit an active light pulse toward the scene; an array of detectors configured to receive light for a field of view that includes at least a portion of the scene, each detector in the array of detectors configured to produce a linearized response to a number of incident photons of light; control circuitry operably coupled to the at least one emitter and the array of detectors and configured to store at least five successive frames of data as frame pixels in one or more frame buffers, wherein each frame pixel is based on the linearized response from a corresponding one or more of the detectors in the array of detectors, wherein a start of the active light pulse is before a start of a capture cycle for each frame, wherein a duration between the start of the active light pulse and the start of the capture cycle is different for each of the at least five successive frames; and a processing system operably coupled to the control circuitry and the one or more frame buffers to generate the image of the scene, the processing system configured to:\n analyze the at least five successive frames of data to determine a minimum intensity value and a maximum intensity value corresponding to each image pixel of the image; and \n generate an intensity value for each image pixel based on a difference between the minimum intensity value and the maximum intensity value of the at least five frame pixels corresponding to the image pixel to reduce an impact of the signal-attenuating environment on the image.
