Abstract: An imaging device is described which, in some examples, includes general pixels and phase difference pixels. The general pixels, when operated by control signals, receive light from a subject and generate currents or voltages that are measured; a depth is estimated based on the measurements. The phase difference pixels generate currents based on a switched charge source. Data obtained from the currents generated by the phase difference pixels is used to adjust the control signals and thereby improve an accuracy of the depth estimation.

Abstract: A Dynamic Vision Sensor (DVS) pose-estimation system includes a DVS, a transformation estimator, an inertial measurement unit (IMU) and a camera-pose estimator based on sensor fusion. The DVS detects DVS events and shapes frames based on a number of accumulated DVS events. The transformation estimator estimates a 3D transformation of the DVS camera based on an estimated depth and matches confidence-level values within a camera-projection model such that at least one of a plurality of DVS events detected during a first frame corresponds to a DVS event detected during a second subsequent frame. The IMU detects inertial movements of the DVS with respect to world coordinates between the first and second frames. The camera-pose estimator combines information from a change in a pose of the camera-projection model between the first frame and the second frame based on the estimated transformation and the detected inertial movements of the DVS.
