Welcome
Welcome to the Construction Information Technology Laboratory (CITL) at the Georgia
Institute of Technology. Our state-of-the-art facility is set up for sensing, information
retrieval, and knowledge discovery from infrastructure data. The research projects housed
in the laboratory focus on the extraction and analysis of unstructured and semi-structured
data, such as images, video, and the geometry of construction projects. The laboratory
also houses education, outreach and engagement activities that relate to its mission. This
includes demonstrations for graduate and undergraduate students, hands-on activities for
K-12 students, student experiments for class projects, and others.
Experiments that take place in this lab commonly involve the real-time collection of data
using intensity, infrared, and positioning sensors placed on the lab's testbeds and the
subsequent pre-processing and analysis needed to extract information using pattern
recognition tools for object detection, segmentation, abnormal pattern extraction and
other purposes that serve the objectives of each research project.
The laboratory is temperature and humidity controlled, with natural light, and equipped
with:
• Two actual, miniature scale, photorealistic infrastructure models/testbeds for
controlled reality capturing and machine vision experiments.
• Ten workstations, each with desk and shelf space, drawers, and a computer with two
monitors.
• Network printer and scanner.
• Four 3.1 Megapixel Lumenera Le375 laboratory video cameras capable of streaming
2048 x 1536 resolution at 10 fps over a standard 10/100BaseT network interface.
• One PMD 3k-S range imaging camera capable of streaming 64 x 48 range pixels at 10 fps
over a standard 10/100BaseT network interface. Suppression of background illumination (SBI)
is available at every pixel.
