The blog post introduces an innovative concept for a computer vision system that automatically identifies climbing routes from a photo of a climbing wall. It would analyze features such as color-coded routes and different hold types (e.g., jug, crimp, sloper). Additionally, using geometry and physics, the system would create a personalized climbing plan (beta) for the climber, tailored to their skill level and technique. The post explores the potential for smarter climbing experiences through AI and technology.
