PS-Tech's 3D localization technology is integrated within Microflown's Scan & Paint 3D Solution, which aims to reduce the sound generated by different products, from gadgets to cars and airplanes.
One of the most important steps in order to reduce the noise produced by a product is identifying its source. To do so, Microflown integrated PS-Tech's PST Iris optical tracker into their solution.
How it works
First, the volume to be analysed is measured with an innovative tool consisting of a sound sensor and multiple passive optical tracking markers (see image). Microflown together with PS-Tech developed this tool to reduce the sound distortion to the minimum in order to get highly accurate sound measurement combined with its 3D position. While this measurement tool is moved around the volume, the sound sensor measures the sound intensity and the PST Iris determines the 3D position and orientation.
The combination of both technologies allows 3D visualization of:
- Sound intensity vectors
- Particle velocity vectors
- Sound pressure distribution
Why did Microflown choose the PST Iris for their solution?
"At Microflown, we integrated the PST Iris optical tracker into our solution because, compared to other 3D positioning systems, it allows us creating a 3D noise distribution colour map around the measured structure with:
- No drift errors
- No requirements for camera recalibration for each test/measurement position
- A very high spatial coverage and resolution. We can measure really small details and merge several big volumes
- Very easy setup
- Non-invasive technology. It does not affect our measurements/sensors"
