Scan & Paint 3D

Description

Sound source localisation is very important when working in the field of sound & vibration; from new product development right through to end off line production control. Scan & Paint 3D from Microflown is a new fast tool to help visualise stationary sound fields in a broad frequency range. This system is an excellent new engineering tool for immediate troubleshooting or benchmarking of all types of objects. In practice, there are many cases where anechoic conditions are not applicable; for example in an industrial manufacturing environment, an engine bay or a car interior. Microflown probe are not really affected by background noise or reflections and are therefore especially suited to situations where there is a high sound pressure over sound intensity ratio. Microflown probes allow direct measurement of sound pressure, particle velocity, sound intensity, sound power and the acoustic impedance. Scan & Paint 3D means that measuring the complete sound field has never been easier and more accurate.

Scan&Paint 3D is a unique tool for acoustic trouble shooting and sound source localization which allows you to visualize and see what you could previously only hear.

THE REAL 3D SOUND INTENSITY PROBE

The state of the art sensor used in the system is the three dimensional 1⁄2 inch USP regular probe. The sensor consists of three orthogonally placed Microflown acoustic particle velocity sensors and a sound pressure microphone. The Microflown USP probe is the only sensor that has the unique capability of allowing the direct measurement of all acoustic quantities: sound pressure and tri-axial particle velocity. The sound intensity can be calculated by taking the time averaged cross spectrum of particle velocity and sound pressure. 3D Sound intensity vectors can be obtained without any frequency limitations covering a range of 20Hz to 10kHz. The actual sensor configuration without the protective cap, occupies a volume smaller than 1cm^3. This small size allows measurements to be taken with an unmatched spatial resolution.

3D POSITION TRACKING USING AN INFRARED CAMERA

The sensor´s orientation and position are automatically tracked in 3D by the tracking camera. The optical tracking system is based on monitoring a defined measurement space using an infrared stereo camera.Each camera is equipped with an infrared (IR) pass filter in front of the lens, and a ring of IR LEDs around the lens to periodically illuminate the measurement space with IR light. This light is not visible to the human eye and is completely safe to work with.The sensor is equipped with a spherical marker, consisting of embedded retro reflective stickers. The incoming IR light is reflected by the stickers. The IR light reflections are detected by the stereo camera, and the tracking system translates them to exact 3D coordinates along with the sensor orientation.

3D MODEL | CREATE, IMPORT OR DIGITIZE

All results can be visualized on an interactive 3D model. The built in 3D Shape Editor offers a variety of options to create a 3D model.The 3D shape editor offers a drawing tool to quickly create basic models. If your 3D geometry is already available, the 3D shape editor is equipped with the possibility to import 3D models from a variety of popular file formats e.g. CAD or Sketchup files.Alternatively, if no model is availably for import, a fast method using a Structure Sensor to obtain a detailed 3D model can be offered. The Sructure Sensor can be used either with an Ipad or normal PC and provides you with a 3D model in a compatible import format for the 3D shape editor in a matter of minutes.
