A ski instructor spends hours correcting postures in the snow. 3D technology makes it possible to capture the student's movement with LiDAR sensors and depth cameras, generating a digital model that reveals deviations in body alignment. This accelerates technical correction without relying solely on the instructor's eyesight.
Workflow with photogrammetry and volumetric capture 🎿
The process requires a 3D camera like Intel RealSense or an iPhone with a LiDAR sensor. Agisoft Metashape software reconstructs the static posture, while programs like Blender or Maya allow analyzing the angle of the knees and hips in motion. For animation, tools like Rokoko Studio or Captury are used, which process video in real-time. The instructor exports the model to a 3D viewer like Sketchfab to review the session with the student.
When the snowman corrects better than you ⛄
Imagine the student recorded in 3D with arms as stiff as a scarecrow. You show them their digital model and they say it's the scanner's fault. You rotate the model 360 degrees and even their shadow seems to judge them. The worst part: the program points out that their posture is identical to that of a beginner from three classes ago. At least, now you can blame the software and not your patience.
