Abstract: A multi-camera imager (MCI) configured to register a first image of a scene acquired by a first camera comprised in the MCI to a second image of the same scene acquired by a second camera in the MCI based on adjusting a transform configured to register images of a calibration target acquired by the first and second cameras for a same fixed position and orientation of the calibration target using epipolar line segments in one of the cameras associated with image plane coordinates in the other of the cameras.

Abstract: Various embodiments relating to reducing camera interference are disclosed. In one embodiment, an infrared image of a scene may be received from a camera that emits infrared light. An interference condition likely to degrade infrared performance of one or more proximate infrared devices may be recognized. Responsive to recognizing the interference condition, an instruction to mitigate the interference condition may be output.

Abstract: A method for operating a time of flight (TOF) depth camera is provided. The method includes, using an image processing module, interpolating an updated timing delay calibration for each of a plurality of pixel sensors based at least on an updated set of modulation frequency and duty cycle calibration combinations received by the image processing module, the plurality of pixel sensors coupled to a timing clock, and receiving light generated by a light source and reflected in a 3-dimensional environment, the updated set of modulation frequency and duty cycle calibration combinations replacing the corresponding factory-preloaded timing delay calibrations. The method further includes applying the updated timing delay calibrations to pixel data corresponding to each of the plurality of the pixel sensors to generate a depth map of the 3-dimensional environment.

Abstract: An active illumination range camera that acquires a range and a picture image of a scene and provides a reflectance for a feature in the scene responsive to a distance for the feature provided by the range image, a registered irradiance for the feature provided by the picture image and registered irradiance for a region of a calibration surface corresponding to the feature provided by an image of the calibration surface acquired by the range camera.
