# Wheat3DIS



## Wheat3DIS-Laser

In Wheat3DIS-Laser, there are three semantic classes with ids `0`, `1`, `2` with valid semantic ids starting at `0` (`-1` for in valid). Ony class-id `2` i.e. the wheat-head class have instance labels. Valid instance ids start at `1`. Points with instance-id `0` either belong to stuff classes or background.


| Label | Class-ID |
| -------- | -------- |
| stem    | 0    |
| leaves    | 1    |
| wheat-heads   | 2    |


The dataset contains 4 files, one for each plot described in the paper. Each file has 6 columns in each row. First three elements for point coordinates (in millimeters), fourth column for intensity and, last two columns for semantic-id and instance-id respectively.

Example:
```
[x, y, z, intensity, semantic-id, instance-id]
```


| Filename | Plot-ID |
| -------- | -------- |
| 9.txt    | D1-P1    |
| 10.txt    | D1-P2    |
| 11.txt   | D1-P3    |
| 12.txt    | D1-P4    |







## Wheat3DIS-MVS


In Wheat3DIS-Laser, there is  only one semantic classs with id `0` with valid semantic ids starting at `0` (`-1` for in valid). This class i.e. the wheat-head class has instance labels. Valid instance ids start at `1`. Points with instance-id `0` either belong to stuff classes or background.

| Label | Class-ID |
| -------- | -------- |
| wheat-heads   | 0   |

The dataset contains 4 files, one for each plot described in the paper. Each file has 8 columns in each row. First three elements for point coordinates (in millimeters), next three are RGB colors and, last two columns for semantic-id and instance-id respectively.

Example:
```
[x, y, z, r, g, b, semantic-id, instance-id]
```
