Belt and waterfall represent identical scan acquisition logis. They differ only in the way live data is visualized.

Data acquisition

When a camera is initialized, data acquisition can be started using the Play button and can be paused by the Pause button. Recording, started by the Record button happens directly to disk.


Live data visualization

In the Waterfall mode, the data moves downward. When reaching the bottom of the screen, data visualization restarts from the top of the screen. This approach can visualize per-pixel decisions but not per-object decisions, that are finalized after the object is already rendered.


In the Belt mode, live data moves upward simulating the top view of an industrial conveyor belt. In this view, perClass Mira can visualize both per-pixel and per-object decisions.


Due to their continuous nature, these modes enable live demonstrations of spectral data processing whether on the stage or industrial belts.

Scanning process on perClass Stage

In the belt and waterfall modes, the scanning and recording process are united. The user initiates Scan and record command that starts both the movement of the stage and recording to disk. Recorded scan cannot be "undone" as it is already stored in a file. In order to remove such as scan, the user needs to remove the corresponding files in addition to removing a scan from project with Remove images command in the context menu of the Images list.
