DLT & Camera Calibration

Algorthms and software for transforming image coordinates into 3D spatial data.

Rigid Body Position and Attitude Estimation

In 3-D kinematic analysis of movement, we typically track the motion of three or more markers on a rigid body segment. Here are various methods to extract a 3-D position vector and rotation (or attitude) matrix from marker coordinates.

3D Analysis of Human Movement

Routines that range from determination of position and attitude of body segments, movement represented as 3-D joint angles, joint moments using equations of motion, to the calculation of other movement parameters.

2D Analysis of Human Movement

Two dimensional (2D) analysis is easier, faster, and sometimes more accurate than 3D analysis in some circmumstances. However, one must be aware of errors when applying 2D analysis to motion with significant out-of-plane components. Here are some software tools for 2D motion analysis.

Force Plate Analysis

Two dimensional analysis is easier and faster, and sometimes more accurate than 3-D analysis. One must, however, be aware of errors when applying 2-D analysis to motion with significant out-of-plane components.
