Automatic Fixing of Foot Skating of Human Motions from Depth Sensor
نویسنده
چکیده
This paper presents a real time algorithm for solving foot skating problem of a character whose motions are controlled in on-line puppetry manner through motion depth sensor such as Kinect. The IR(Infrared Light) projection based motion sensor is not perfect for reconstructing 3D poses of the user because it is very sensitive to occlusion and light condition. One significant artifact is foot skating, which means that feet are floating over the ground even when the character is standing still. Our algorithm is working as a post processing that applies the orientation data from sensors to a character first, and then keeps monitoring the current character status and applying foot skating solver next whenever the problem occurs. The core of this algorithm is a modified IK(Inverse Kinematic) solver with fixed target foot positions that are detected by checking positional and velocity threshold. Inter-frame smoothing is followed to make sure there is no discontinuity on the motions.

This paper describes the development of a novel humanoid robot foot/ankle based on an orientation Parallel Kinematic Mechanism for intelligent and flexible control. With three identical Universal-Prismatic-Spherical prismatic-actuated limbs and a central Universal-Revolute passive limb, the PKM can perform three degrees of freedom rotation motions. In order to enable the humanoid robot safely t...
متن کاملFrom a One-Legged Vertical Jump to the Speed-Skating Push-off: A Simulation Study
To gain a better understanding of push-off mechanics in speed skating, forward simulations were performed with a model comprising four body segments and six muscles. We started with a simulated maximum height one-legged jump, obtained by optimization of muscle stimulation time histories. The simulated jump was very similar to one-legged jumps produced by a human, indicating that the model was r...
متن کاملAutomatic Identification of Subtechniques in Skating-Style Roller Skiing Using Inertial Sensors
This study aims to develop and validate an automated system for identifying skating-style cross-country subtechniques using inertial sensors. In the first experiment, the performance of a male cross-country skier was used to develop an automated identification system. In the second, eight male and seven female college cross-country skiers participated to validate the developed identification sy...
متن کاملA Simple 2-dimensional Model of Speed Skating Which Mimics Observed Forces and Motions
Advice about the optimal coordination pattern for an individual speed skater to reach their optimal performance, could well be addressed by simulation and optimization of a biomechanical model of speed skating. But before getting to this optimization approach one needs a model that matches observed behavior. In this paper we present a simple 2-dimensional model of speed skating on the straights...
