What a camera needs to see plate bounce on a textured wine label
The encoder must land on the spot after the gap. A steady sight needs about 3 pixels. If you cannot see it clearly, do not loosen the threshold.
To see plate bounce on a textured wine label, the encoder must land on the spot after the gap. If you cannot see it, change the light or the resolution first. Do not loosen the threshold first.
If you cannot see it, change the optics first
A bar in a fixed place after the gap or the gripper margin. If the image cannot separate them at all, moving the threshold only paints the wine name and the fine type solid red. The encoder must land on the spot after the gap.
Optics
| Need | Enough looks like | Not enough looks like |
|---|---|---|
| The encoder must land on the spot after the gap. | A bar in a fixed place after the gap or the gripper margin. | Only a blurry circle left |
| About 3 pixels across | Shows up steadily | Comes and goes, and you still write that it can be detected |
| Wine name and fine type in the field of view | The critical spot is seen | Only the decorative edge is lit |
Try it on a sample
- Confirm the image can separate it: A bar in a fixed place after the gap or the gripper margin.
- Count about how many pixels it spans.
- If you cannot see it clearly, change the light or the focus. Do not change the threshold.
