Super-Resolution LIDAR Data

Recently, the use of LIDAR sensors and data have transitioned from the domain of research and development into the general marketplace primarily as a mean of rapidly generating dense, accurate, digital models of the topography and vertical structure of target surfaces. Latest industry reports have shown that the demand for LIDAR technologies is growing faster than supply. For 2012, annual sales are expected to grow to $330 million based on technology developments, new application areas, and trends in data acquisition and processing techniques. Recognizing the opportunities, researchers at Utah State University developed a method that improves the ability to obtain high-fidelity high-resolution LIDAR point-clouds to enhance three-dimensional (3D) imagery in real time.
Features and Benefits
  • Military
  • Digital Imaging
  • Telecommunications
  • Urban planning and mapping
  • Meteorology
  • Geology
  • Physics and Astronomy
  • Biology
  • Law Enforcement
  • Processes multitude of point-clouds, which improves the ability to achieve an increased resolution of shape information from long distances
  • Measures more broadly spaced 3D points, enabling the draping of detail spectral (texture) information onto a relatively coarse surface shape
  • Makes precise distance, shape and size of target measurements over long or short distances, improving the ability to achieve an increased resolution
The LIDAR and camera system collect data and generate a three-dimensional (3D) image. The LIDAR generates a laser beam to form a LIDAR shot and receives the reflected laser beam to provide range data. A digital camera includes an array of pixels to receive optical radiation and provide electro-optical (EO) data, which is much more dense. This post-processing technique utilizes dense EO data to combine multiple LIDAR shots to improve LIDAR resolution.
Development Stage
The Texel Camera prototype exists for specific fields of use. Continuous testing for improvements is ongoing.
