Single-Pass Inline Pipeline 3d Reconstruction Using Depth Camera Array, Zhexiong Shang, Zhigang Shen 2022 University of Nebraska-Lincoln

Single-Pass Inline Pipeline 3d Reconstruction Using Depth Camera Array, Zhexiong Shang, Zhigang Shen

Faculty Publications in Construction Engineering & Management

A novel inline inspection (ILI) approach using depth cameras array (DCA) is introduced to create high-fidelity, dense 3D pipeline models. A new camera calibration method is introduced to register the color and the depth information of the cameras into a unified pipe model. By incorporating the calibration outcomes into a robust camera motion estimation approach, dense and complete 3D pipe surface reconstruction is achieved by using only the inline image data collected by a self-powered ILI rover in a single pass through a straight pipeline. The outcomes of the laboratory experiments demonstrate one-millimeter geometrical accuracy and 0.1-pixel photometric accuracy. …

The Effect Of Inflation And The Pandemic On A Southern California Solar Company: A Case Study, Adrian Avila

Construction Management

Supply chain issues are causing panic in certain sectors of the economy particularly the solar sector. Solar energy already has problems that can affect its growth in the long term such as lack of government incentives, high cost, and energy curtailment. These problems are becoming more pronounced as the pandemic is prolonged. California is a state that has been encouraging the use of solar energy and has introduced incentives for its citizens to install solar. Because of this, solar companies in California may be able to more adequately circumvent issues and better excel economically than companies in other states. In …
