A parallel implementation of a surface reconstruction algorithm is presented. This algorithm uses the vector field surface representation and was adapted in a previous work by the authors to handle large scale environment reconstruction. Two parallel implementations with different memory requirements and processing speeds are described and compared. These parallel implementations increase the vector...
This paper presents a simple, effective, yet fast out-of-core method for surface reconstruction based on the vector field surface representation. The algorithm is designed to handle massive amount of real-world point clouds representing large infrastructures (e.g. underwater hydroelectric structure) acquired by LiDAR, sonar or laser scanning system using out-of-core techniques. Our method allows performing...
A review of the current state-of-the-art computer vision applied to the management of power transmission lines is presented. It covers the highest value applications for electric utilities, with a specific interest for applications dedicated on the cable system. Although robotics provides additional means of data collection, this review is not centered on specific platforms. Strategic steps that could...
In the past years, a laser scanning system to measure hydraulic gate frames with high precision was developed by Hydro-Québec. Inspired by this first design, a new compact and lower cost platform was developed. The WireScan technology is actually applicable to measure the geometry of any structure that is vertical and underwater. The applicability of this technology was further extended with improvements...
