“…Another emerging technology is wrist-worn motion sensors which track the climber in action [13,17,18,20]. The biomechanics of rock climbing has also been studied using instrumented indoor walls, i.e., with artificial holds equipped with built-in force sensors [2,25]. Measuring forces on natural rock walls would require invasive installations, therefore we focus on kinematics which can be inferred from video.…”

Despite rapid advances in 3D printing, fabricating large, durable and robust artifacts is impractical with current technology. We focus on a particularly challenging environmentscale artifact: rock climbing routes. We propose a prototype fabrication method to replicate part of an outdoor climbing route and enable the same sensorimotor experience in an indoor gym. We start with 3D reconstruction of the rock wall using multi-view stereo and use reference videos of a climber in action to identify localized rock features that are necessary for ascent. We create 3D models akin to traditional indoor climbing holds, fabricated using rapid prototyping, molding and casting techniques. This results in robust holds accurately replicating the features and configuration of the original rock route. Validation was performed on two rock climbing sites in New Hampshire and Utah. We verified our results by comparing climbers moves on the indoor replicas and original outdoor routes.

“…It is often challenging to locate contact regions manually, since many rock features look alike. Note that accurate measurement of contact forces is unfeasible without additional sensors, e.g., using instrumented artificial holds [2,25].…”
