AQSense added plenty of new functionality to it's 3D Express tool

3DExpress base package:

• Acquisition Drivers
• COG (center of gravity) Laser Detector
• Presence Detection
• Static Linear Calibration
• Plane Fitting / Alignment
• C/C++ Interface
• .NET Interface
• Sherlock plug in

3DExpress add-ons:

• Lens Distortion Calibration
• SAL3D Peak Detector (laser detector)
• Linear Metric Calibration
• Match3D Alignment

The 3DExpress documentation describes all the new functionality in detail. Further you find a short summary for each add-on.

Lens distortion tool: same as in SAL3D, it allows to remove the lens distortion using a dots or chess pattern.

Peak detector tool: same as in SAL3D, it allows to have more resolution and accuracy compared with the COG on the base package. This peak detector also allows:

• Extract the laser width, that can be used to generate a width map (scattering applications). This (also for the COG). This additional information can be also mapped over the COP data
• Extract the laser intensity, that can be used to generate a light map (also for the COG). This additional information can be also mapped over the COP data
• Split the camera image in two regions, to apply the peak detector independently in both of them (also for the COG).

Linear Metric calibration: compare to the static available in the base package it allows:

• Work with tilted lasers
• Allows to combine information from two lasers and a single camera (with 2 ROIs)
• Does not require a good alignment of the pattern
• Estimate the encoder step

Match3D Alignment: with this add-on two additional outputs are possible:
Disparity map (2D comparing of two COPs after alignment)
Aligned ZMap (see the benefits)
