3.3 Candidate Classification

Fig. 64 Candidate Selection - Candidate Classification

Choose the profile of a good candidate

In the candidate classification stage, you have to define what is a good candidate and what is a bad candidate. A good candidate is a candidate which is well oriented for robot pick-up (Fig. 65) and bad candidates are all of the other orientations.

Fig. 65 Good candidate

Fig. 66 Bad candidates

Once you have defined the right orientation of your part for robot pick-up, you can feed the right side of the window with all candidates that match the profile and feed the left side with the candidates that do not match.

You must place at least 15 candidates on each side.

Note

It is good practice to fill the right and left side with as much variation as possible in each good and bad category in order to increase the AI algorithm robustness.

Astuce

You can avoid classifying an image by dragging it down. For example, if one side of the database is already filled and you only want to finish filling the other side.

Astuce

You can use your computer’s keyboard arrows instead of right-clicking on the icons .

Note

If you don’t have enough images to finish filling both sides, you can go back to the previous step and take more images.

Apply classification

Click on the APPLY CANDIDATE CLASSIFICATION to train the classification model according to the candidates provided.

By placing the images on the right or left side, you have associated each candidate to a label (good or bad). When you apply the classification, these images with their label will feed a neural network that will enable EYE+ to distinguish the good and the bad candidates.
