Z-Expert GUI
Z-Expert interface consists of a configuration section to set the features your 3D Camera sensors, and a display pane to show the results of acquisitions. The different windows of the configuration section can be hidden/shown, resized, and reorganized within the interface (pane, standalone window, etc.).
Multi-Sensor Systems
Several Z-Trak profiler sensors may be configured over or around an object to enlarge the measurement area, measure different areas of interest, or eliminate occlusion. In some cases, profile acquisition may be triggered synchronously or in sequence between sensors. In other cases, a larger, unified measurement space (UMS) can be created, such that all sensors report measurements within the same coordinate system.
Multi-Sensor Configuration and Unified Measurment Space (UMS)
3D inspection applications requiring 360° views, thickness measurement, an extended horizontal field of view without sacrificing the z-resolution or removing occlusion etc. require the combination of multiple profile sensors.
Combining and synchronizing multiple Z-Trak 3D Camera sensors helps create a Unified Measurement Space so that applications view the resulting 3D measurements from the point of view of the entire system. The 3D applications benefit from consistent, accurate and easier to handle object measurements and for added flexibility, the Z-Trak LP architecture also enables models with different measurement ranges and laser colors to be combined.
