High Definition Laser Scanning: 3D Imaging


high definition laser scan interior

Surveying or land surveying is the technique, of accurately determining the terrestrial position of points and their distances and angles between them. Three-dimensional laser scanning provides high definition surveying for architectural, as-built, and engineering surveys. Recent technological advances make it the most cost-effective and time-efficient solution for providing the highest level of detail available for professional work.

registered point cloud scan world

The Leica HDS ScanStation is at the forefront of laser scanning providing accurate spatial information. Scanning provides a point cloud, in which a series of points (thousands to billions) represent the built environment digitally. From this data it is possible to produce accurate 3D models in a variety of applications (Cloudworx, AutoCAD, Revit, rhino, etc.) Modeling off of scan data provides for the most precise as-built models possible. Additionally scanning can be used to survey a site to provide information before design even begins.

Scan Station 2

The Scanner used in this project was the Leica ScanStation 2. Utilizing LIDAR, (Light Detection And Ranging, also LADAR) which is an optical remote sensing technology that can measure the distance to, or other properties of a target using light pulses from a laser. LIDAR technology has application in geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, remote sensing and atmospheric physics,[1] as well as in airborne laser swath mapping (ALSM), laser altimetry and LIDAR contour mapping. The acronym LIDAR is often used in military contexts. The term "laser radar" is sometimes used, even though LIDAR does not employ microwaves or radio waves and therefore is not radar in the strict sense of the word.

Studio 4: Presidential Library


presidential Library from I25

The Thomas Jefferson Center for Civics is a civil service hub located on the Eastern edge of the United States Air Force Academy campus. Driven by the exponentially changing cultures, technologies, and politics the Center is geared for the world of tomorrow. Designed as a utility to help inform the study of Civics World Wide.

auditorium

The site's defining characteristics are a continuation of the USAFA Airport axis aligning with the building’s main entrance. This entrance axis continually rises through the building as program is developed, terminating at the fellowship wing. The earthbound learning wing captures the progressive airport energy and acts as a foundation of the Fellowship Wing. Literally Supporting the Principles of the Fellowship, and reinforcing our civic duty through education. Captured between the Research Wing and Public Presidential Library are the media Screens, Streaming local and world news, along with the Fellowships latest Research. The screens provide transparency for the general public into what the fellowship is researching. The screens also provide a backdrop for the public lyceum and are easily visible to motorists on I-25. The Great hall and museum provide public event space, and support the facilities main functions. To the south of the Museum spaces there are a series of Terraced Jeffersonian Gardens Providing a unique exit progression.

Studio 4: Hexagonal aperture Screen

IMage of prototype model The aperture wall system was influenced by a camera shutters shape and operation, along with Jean Nouvel's Institue du Monde Arabe, dilating facade. The wall system is designed to dynamically regulate lighting conditions based off program. It is a static diameter but by utilizing parametric design the aperture diameters can be controlled based off very specific parameters. The honeycomb pattern of nested hexagons creates a elegant and unique design while proving to be incredibly durable.

Image of Grasshopper Definition Utilizing Rhino 3D modeling software and Grasshopper, a complex definition has been created to adapt the screen to any given surface conditions. Thus allowing for infinite possibilities of form.
Further developments not shown are the addition of control curves that dictate the size of the aperture openings.

Model from GH definition

Image of Grasshopper Definition The first prototype model was created using simple developable surfaces. The individual honeycomb extrusions were unrolled and then oriented onto optimized cut sheets, laser cut out of poster board, and then finally assembled by hand.

Rendered representation of final wall

After experimenting with cnc milling and casting "bricks" we determined that due to time constraints and afford-ability that the wall should be built out of laser cut paper modules. The rendering to the right was a representation of the final assembly

Final paper wall on display

The final display wall consisted of 120 hexagonal apertures. The wall was held together using a series of zipper and staple connections. In the end the wall was free standing. The project received rave reviews all around
