Systems and methods for illustrating the flight of a projectile
A system for illustrating the flight of a sports ball includes a radar, an imager, and a controller. The imager is configured to image a moving sports ball. The controller is configured to (i) receive, from the imager, an image including the moving sports ball, (ii) receive, from the radar, radar data associated with the moving sports ball, (iii) determine, from the radar data, a portion of a trajectory of the moving sports ball, (iv) alter the image to illustrate the portion of the trajectory relative to the moving sports ball, and (v) output the altered image.
1. A method, comprising:
providing a first imager and a radar, the first imager and the radar being calibrated to correlate data from the radar relating to a moving object to positions within images from the first imager using a first calibration setting;
detecting a first change in the field of view of the imager by comparing first and second images from the first imager; and
determining a second calibration setting based on the first change in field of view of the first imager to correlate data from the radar relating to the moving object to positions within images from the imager subsequent to the first change in the field of view of the first imager.
2. The method of claim 1 , wherein the first imager is movable relative to the radar.
3. The method of claim 1 , further comprising inserting a graphic representation of a trajectory of the moving object into images from the first imager based on the second calibration setting.
4. The method of claim 1 , further comprising correlating data from the radar relating to the moving object to positions within images from a second imager fixed relative to the radar using a third calibration setting.
5. The method of claim 4 , wherein the positions within the images from the second imager are correlated to positions within the first imager based on positions of elements visible in images from both the first and second imagers.
6. A system for tracking a moving object, comprising:
a first imager;
a radar; and
a processing unit calibrating the first imager and the radar to correlate data from the radar relating to a moving object to positions within images from the first imager using a first calibration setting, the processing unit detecting a first change in the field of view of the imager by comparing first and second images from the first imager and determining a second calibration setting based on the first change in field of view of the first imager to correlate data from the radar relating to the moving object to positions within images from the imager subsequent to the first change in the field of view of the first imager.
