Photometric Capture and What Four Cameras Catch
A single camera can tell you a lot about a golf shot. Four synchronized cameras, watching from different angles at once, tell you the parts a single lens has to guess at.
Most golfers assume a launch monitor uses one sensor, whatever the marketing brochure calls it. Ours doesn't run radar at all — the capture wall is entirely optical, which means the honesty of the data comes down to how many independent angles are watching the ball at the moment it leaves the face.
Why One Camera Isn't Enough
A single high-speed camera can read ball speed and launch angle reasonably well along its own line of sight, but it loses accuracy fast on anything happening off-axis — spin axis tilt, for example, or a curve that starts developing in the first few feet of flight. One lens simply can't triangulate depth the way a stereo pair can.
What the Fourth Camera Actually Buys You
Two cameras give you stereo depth. Three add redundancy. The fourth is there specifically for strikes that come in off-center or slightly toed, where one or two of the other angles can get partially blocked by the club itself during the split second of impact.
A mis-hit is exactly the swing you most need accurate data on, and it's also the swing most likely to confuse a two-camera system.
How the Four Views Get Reconciled
Each camera logs its own read on ball position across a sequence of frames. Those four tracks get reconciled into a single 3D flight path, and if one camera's read disagrees meaningfully with the other three, that swing gets flagged for a manual look rather than silently averaged in.
Where the Impact Plate Comes In
The camera wall reads the ball. It doesn't read the club. That's what the pressure-mapped impact plate under the mat is for — strike location, dynamic loft, and dynamic lie, captured independently and cross-checked against whatever the four cameras logged for that same swing.
