Resolution compensation

For scanners with rotating mirror technology object area covered by each scan line pixel differs along the line. This is also true for devices with detector array technology (like 2D IR cameras), when the device is looking at the kiln not straightly. This pixel resolution difference are automatically compensated by IRT KilnMonitor.

Scanned data gathering and position around the kiln circumference

1.For each scanner and pyrometer temperature data scanned during the period between two kiln trigger signals are buffered in the memory. Each line is stored together with its timestamp.

2.Memory buffer size for one revolution is limited to 4096 lines (constant, cannot be changed) per each scanner and pyrometer. In extreme cases (slow kiln rotation, fast scanning rate), when the buffer is full and a new line is received, every second line is removed from the buffer to free space.

3.When the kiln trigger signal is received the buffered lines are used to render next kiln shell image.

4.Line timestamps are used to map scanned lines to kiln shell image lines.

5.If several scanned lines correspond to one image line they are merged using the maximum operation.

6.If there are no scanned lines found, the image line is interpolated using scanned lines with the closest timestamps.

7.If kiln rotation speed is changing IRT KilnMonitor estimates acceleration and corrects lines distribution accordingly. This is done automatically, no configuration is needed.

Scanner and pyrometer data render order

The fields of view of the scanners may overlap. The positions of the pyrometers may also overlap, both with each other and with the scanners.

You need to decide what source to use for overlapping areas.
