20150262011 | IMAGE PROCESSING FOR LAUNCH PARAMETERS MEASUREMENT OF OBJECTS IN FLIGHT - An example embodiment includes a method of measuring launch parameters of an object in flight. The method includes capturing images of an object in flight. A radius of the object and a center of the object are identified in each of the images. A velocity, an elevation angle, and an azimuth angle are calculated based on the radius of the object, the center of the object, and pre-measured camera alignment values. The method further includes cropping the images to a smallest square that bounds the object and flattening the images from spherical representations to Cartesian representations. The method also includes converting the Cartesian representations to polar coordinates with a range of candidate centers of rotations. Based on a fit of the polar image pair, the spin axis and spin rate are measured. | 09-17-2015 |
20140028838 | MEASURING LAUNCH AND MOTION PARAMETERS - An example embodiment includes an apparatus for monitoring launch parameters of an object. The apparatus includes a transmitter optical subassembly (TOSA), a receiver optical subassembly (ROSA), a processing unit, and a camera. The TOSA includes at least one laser source configured to transmit a laser sheet along an expected flight path of an object. The ROSA is configured to receive light reflected from the object. The processing unit is configured to estimate a velocity of the object based at least partially on the received light. The camera is configured to capture one or more images of the object at a time in which the object passes through a field of view of the camera according to the estimated velocity. | 01-30-2014 |
