Noisy data caused by reflections is automatically removed by the Point Cloud Denoiser software after the scanning is completed.
Laser Design has released Laser Design Point Cloud Denoiser (3D) software, for the scanning of parts with reflective surfaces.
The DeNoiser software reduces or eliminates the need to spray surface treatments, powders, paints or finishes on parts with reflective surfaces because the noisy data is automatically removed by the Point Cloud Denoiser software after the scanning is completed.
The actual surface data is left intact by the software's proprietary denoising algorithms.
Point Cloud DeNoiser automatically removes both long-range and short-range noise.
The software identifies and deletes discrete and clustered outliers without moving any of the input data points.
The software's algorithm also excels at removing structured point data usually associated with reflections.
The Denoiser saves the most time of any data processing product on the market for high-density scanning applications.
The amount of time spent cleaning up scan data to eliminate excessive or minute noise in scan files can be more than 50% of the time spent on the entire data processing project.
The Point Cloud Denoiser automates the whole noise reduction process for 3D data from any scanner that uses industry-standard file formats.
No additional operator training is necessary.
Noisy data removal is crucial for industries that use scanning technologies for their reverse engineering, quality inspection and object recognition applications such as automotive, aerospace, electronics, telecommunications, medical device, consumer appliance and tooling manufacturing.
In addition, the DeNoiser can eliminate the interactive operator time needed for data editing on any 3D scan data files, including huge terrestrial laser scanning projects such as a building, power plant interior or land contours.
Large-scale terrestrial scanning in less than optimum conditions results in scans with the most noise and errant flier data points.
By eliminating the need for surface sprays, the reliability of laser scanning results for inspection applications is heightened since parts will no longer be deformed by the application of a messy surface spray.
Many more applications for scanning parts will be viable because there is no part contamination: for example medical, electronics components / circuit boards, clean room parts, machined metal surfaces, polished parts and many high finish, reflective materials that previously could not be scanned without surface sprays.
Some extremely reflective surfaces may still need surface preparation.
