ReliaSolve worked with Baseball Cloud and YakkerTech on the calibration approach for their next-generation 6-camera pitch-tracking system. ReliaSolve designed a complete workflow that incorporated their existing factory distortion correction and stereo alignment algorithms to meet their precision and time requirements as well as their requirement that the entire calibration kit fit within a 3’x2’x1.2′ carrying case. We also designed the 2D patterns and designed and printed 3D fiducials for holding the patterns on standard microphone stands to align them with better than 1/4″ accuracy to home plate and the pitching mound.
