Introduction
Starting from version 2.5.0.158, iPi Mocap Studio includes experimental support of Triple Depth Sensor configuration. It helps to solve occlusion problems thus allowing to record more complex motions and to track two actors with depth sensors. The quality is comparable with 6 PS Eye configuration but the capture area is smaller (about 2.5 by 2.5 meters).
The usage of Triple Depth Sensor configuration is similar to Dual Depth Sensor configuration except the following aspects:
- Triple Depth Sensor configuration requires Standard Edition. In other editions export is disabled for projects with Triple Depth Sensor configuration.
- Recording from three depth sensors requires at least three separate USB 2.0/3.0 controllers in your PC, similar to recording with 6 PS Eye cameras. More info on USB controllers.
- Calibration of Triple Depth Sensor configuration can be performed only with glowing marker like flashlight.
Please note, this feature is currently at experimental stage.
Scene Set-up
The point is, in ideal case, depth sensors should be placed at vertices of equilateral triangle with side is about 6 meters:
In real conditions it is not always achievable due to free space size and/or configuration, mount positions, USB and/or power cord lengths, etc. Thus, sensor positions may slightly differ from ideal ones. Here is example from real mocap session:
Calibration
To calibrate Triple Depth Sensor configuration glowing marker should be used:
Calibration procedure is almost the same as described in the following article: Dual Depth Sensor Calibration using Flashlight.
The result of calibration should look like the following:
Other
Other aspects of Three Depth Sensor configuration are the same as for Dual Depth Sensor configuration. It includes performance video recording, processing, clean-up and export.
