Installed ten multi-sensor installations (and counting) throughout 2014 & early 2015 using OpenPtrack, a scalable open-source tool for person detection and tracking using an arbitrary number of cameras and computers.
Along the way, extensively debugging, documenting, and working w/ initial developers to extend the functionality and usability of what is a complex (and frankly pretty amazing) tool.
Next up is a permanent installation on UCLA campus, an overhaul of documentation, and code modification to allow realtime control of calibration parameters.
