A system and method for determining a position an object moving along a trajectory crosses a target plane, by obtaining a plurality of images of an object moving along a trajectory in an environment, the plurality of images capturing the object at different positions along the trajectory, obtaining a plurality of images of an object moving along a trajectory in an environment, the plurality of images capturing the object at different positions along the trajectory, the plurality of images being obtained from two or more cameras positioned at different positions in the environment, each of the two or more cameras having a field of view (FOV) that includes the trajectory of the moving object and a target plane, the target plane being a plane that the moving object crosses during movement along the trajectory, each of the two or more cameras obtaining the images at a different timing.

Embodiments are disclosed for a range-gated imager. In some embodiments, a method comprises transmitting, with a multi-tone continuous wave (MTCW) radar, a radar signal comprising a first tone and a second tone, where the first tone and the second tone are separated by a frequency gap; receiving, with the MTCW radar, a return signal from a projectile impinged by the radar signal; detecting, with a measuring apparatus, a zero crossing of a phase difference between the first and second tones; and responsive to detecting the zero crossing, gating or triggering, by the measuring apparatus, an imager to capture an image of the projectile.

A method for calibrating a camera without the decomposition of camera parameters into extrinsic and intrinsic components is provided. Further, there is provided a method for tracking an object in motion comprising capturing one or more image frames of an object in motion, using one or more calibrated cameras that have been calibrated according to a calibration method that generates and uses a respective transformation matrix for mapping three-dimensional (3D) real world model features to corresponding two-dimensional (2D) image features. The tracking method further comprises determining, using a hardware processor, motion characteristics of the object in motion based on the captured one or more image frames from each one or more calibrated cameras, the determining of the motion characteristics based on implicit intrinsic camera parameters and implicit extrinsic camera parameters of the respective transformation matrix from each respective one or more calibrated cameras.
