Open-source climbing CV tool uses SAM3.1 and pose models to quantify your hand and foot placements

spillai · x · 2026-09-16

Developer jeremyparkphd open-sourced a computer vision tool for bouldering analysis in the vision-demos repo (212 stars).

• Uses SAM3.1 to segment climbing holds and vitpose-plus-large for pose estimation, identifying which holds a climber used and in what order
• New analytics show what percentage of total time hands and feet are on holds, and which holds each limb uses
• Use cases: quantify foot/leg usage as a baseline for improvement, and compare climbing sequences on the same route between friends
• The repo also includes demos for chin-up counting, dance sync scoring, and running cadence/knee-angle analysis, all Apache-2.0 licensed
