bCode detector

Raw bCode detections, which can be converted to a more useful format, are stored as a comma-separated text file without a header. Each line describes one detection and provides the following information:

1. image timestamp
2. top-left fixed pattern, x-coordinate
3. top-left fixed pattern, y-coordinate
4. top-right fixed pattern, x-coordinate
5. top-right fixed pattern, y-coordinate
6. bottom-left fixed pattern, x-coordinate
7. bottom-left fixed pattern, y-coordinate
8. ID of bee
9. a mysterious number

The timestamp format is Unix time with millisecond precision.

Converter

Converted bCode detections are stored as a comma-separated text file without a header. Each line describes one detection and provides the following information:

1. image timestamp
2. x-coordinate
3. y-coordinate
4. orientation vector, x-component
5. orientation vector, y-component
6. ID of bee

The timestamp format is Unix time with millisecond precision.

Movement detector

Movement is stored as a comma-separated text file without a header. Each line describes one movement and provides the following information:

1. image timestamp
2. ID of bee
3. distance moved in mm

The timestamp format is Unix time with millisecond precision.

Trophallaxis detector

Trophallaxis detections are stored as as a comma-separated text file without a header. Each line describes one detection and provides the following information:

1. image timestamp
2. ID of bee 1
3. ID of bee 2

Begin and end times are Unix time with millisecond precision.
