Abstract: A system and method of stereoscopic image processing by at least one processor may include receiving, from a first imaging device, having a first field of view (FOV), and located at a first, initially unknown position, a first image of a scene; receiving, from a second imaging device, having a second, different FOV, and located at a second, initially unknown position, a second image of the scene; calculating a plurality of flow lines in the first image, wherein each flow line represents an optical flow between a pixel of the first image and a corresponding pixel of the second image; and calibrating the imaging devices by determining at least one parameter of relative position between the first imaging device and second imaging device, based on the calculated flow lines.

Abstract: A method and system for of relative pose estimation between two or more sensors is disclosed. The system and method may include receiving a time frame, determine expected change in relative pose of at least two of the sensors, within the time frame and expected relations between angular directions of at least two of the sensors, calculating, by a processor, for each sensor a pose shift, calculating for each sensor the sensor's angular directions within the time frame, comparing relations between different sensors' angular directions, at each point in time, based on the expected relations between angular directions to determine a common direction of the two or more sensors, comparing common directions of the two or more sensors between different points in time based on the expected change in relative pose, and estimating the relative pose between the two or more sensors based on the comparison.

Abstract: A system and method of conducting a vehicle by at least one processor may include: receiving sensor data from a plurality of sensor channels associated with the vehicle; for each sensor channel, calculating a three-dimensional (3D) reconstruction data element, representing real-world spatial information, based on said sensor data; for each sensor channel, calculating a channel score based on the 3D reconstruction data element; selecting a sensor channel of the plurality of sensor channels based on the channel score; and conducting the vehicle based on the 3D reconstruction data element of the selected sensor channel.
