From the lab.
How we build object detection, cartography and AI on the device. With real numbers, even when they're not perfect.

Launch monitor numbers explained: ball speed, smash, carry
Ball speed, smash factor, launch angle, spin, carry and landing angle: what a launch monitor's numbers mean and which ones really improve your game.

Golf simulator at home with your phone: setup and costs
Net, mat, light, screen and a phone on a tripod: what a golf simulator at home really needs, how much space it takes and what it costs.

How to connect GSPro to your phone as a launch monitor
Step by step: how DeepSwing sends every shot from your iPhone or Android phone to GSPro on the PC, with fixes for the usual connection problems.

Plays-like distance: how much elevation really changes
Downhill a hole plays shorter, uphill longer, and at altitude the ball flies further. How plays-like distance works, with real numbers from the Alps.

Reading greens with a heatmap: see the slope first
Where is the green high, which way does it fall, how steeply? How a green heatmap is built from laser-scan data, how to read it and its limits.

How to calculate your handicap under the WHS
Score differential, Handicap Index, course handicap and playing handicap: how the World Handicap System calculates, step by step with an example.

How to analyse your golf swing with your phone
Film it right, understand the six swing phases and use 30 checks: how to analyse your golf swing with your smartphone and improve with purpose.

How an iPhone measures ball flight without radar
240 frames per second, two in-house detection models and a physics model: how a phone becomes a golf launch monitor, with carry within 0–2% of radar.

Course AI: how we map golf courses from aerial imagery
A segmentation model on 0.3 m aerial imagery, a learned hole model and laser-scanned terrain: how our course AI works, and how good it really is.

On-device instead of cloud: why our AI runs on the device
Latency, cost, privacy, resilience: why DeepSwing and Pevu run their AI on the phone, and when the cloud is still the right choice.

What should your camera recognise?
Object detection, body tracking, segmentation or cartography, on your device, in real time. Let's talk about it.
