Through Surveying Objects across an Air-Water Interface, the National Research Council of Canada (NCR) is seeking a non-intrusive surveying technology that can accurately measure the surface and profile objects in a laboratory setting that are partially or fully submerged under water.
Solution proposals can only be submitted by a small business that meets all of the following criteria:
- for profit
- incorporated in Canada (federally or provincially)
- 499 or fewer full-time equivalent (FTE) employees
- research and development activities that take place in Canada
- 50% or more of its annual wages, salaries and fees are currently paid to employees and contractors who spend the majority of their time working in Canada
- 50% or more of its FTE employees have Canada as their ordinary place of work
- 50% or more of its senior executives (Vice President and above) have Canada as their principal residence
The program will fund projects that proposed solution Surveying Objects across an Air-Water Interface:
- be able to measure the surface and profile of objects within 1 mm of accuracy in up to 1.0 m of water depth.
- be able to measure the surface profiles of solid objects (concrete, wood, metal, etc.), as well as porous objects such as piles of rocks (with large voids) or topography composed of fine and loose sediments.
- be able to penetrate water that is not completely static (ripples of 1-2cm in heights may still be present on the water surface as well as and currents may still exist on the water surface).
- be non-intrusive (i.e. not come in contact with the objects it is measuring).
- be able to scan the objects from a variety of angles to ensure no gaps or shadow zones exist in the surface profile. If necessary, the scanner can be portable but must then be fairly lightweight so one person can survey large objects in an efficient manner (objects 50m long by 5m wide by 0.5m high may be measured, and this scan should take roughly 1hr to complete).
- generate 3D point cloud datasets that can easily be referenced to a selected coordinate system using targets or reference objects by freely available third party software (i.e. CloudCompare).
- be suitable for hydraulic laboratory settings (safe for human operation in water-filled basins), be able to work in a cordless manner during scans, and be able to penetrate water that may be slightly turbid/dirty.
- allow the resolution of the scan to be adjustable for varying point cloud densities, thus affecting the accuracy of the scan and the time needed for the instrument to survey the area suitable for different applications.
- allow the user to set the scan area/constraints.
- possess the ability to view the scans (even if in low resolution) in near-real time to ensure the coverage area is appropriate.
- be Windows based.
Proposed solutions should:
- be able to measure the surface and profile of objects within 1 mm of accuracy in more than 1 metre of water depth.
