MOTION CAPTURE VS. VIDEO ANALYSIS
How is Retül different than the motion analysis systems (i.e. video) my local shop offers?
-
Video analysis is two-dimensional, even with 2 cameras. Motion Capture is three-dimensional which utilzies a 3-D spatial model. A small error is added to the measurement by not including all three dimensions in the calculation process. Small errors make big differences in bike fit
-
Video cameras have a narrow field of view. Retul sensors have a wide field of view. This means that the video camera must be 1-2 meters further away from the rider to capture the full view of the rider.
-
Video analysis places measurement markers on a small 2-D computer screen; Retul places measurement markers on the rider's body using easy to find skeletal landmarks.
-
Video analysis requires that you manually trace each measurement after the fact with your mouse. Retul automatically performs all the measurements instantly with no manual work.
-
Video analysis takes measurements off of one frame of video, which may or may not be a typical position of the rider. Retul averages all the measurements automatically from each stroke of the recording creating a highly refined model of the average movements of the rider.
