These cannot be used on the NXT. Basically, these types are the same as the types 23 and 24. The major difference is that with these p_patterns, the lead tip is not used for determining the part positioning. The lead width detection results only are used to determine the part positioning. The lead tip detection results are used only as reference data for internal vision processing items.
Type 33: The lead tip appears white, while the lead body appears black. The lead tip half of the outside circumference is black, while the body half is white.
Type 34: The lead tip appears black, while the lead body appears white. The lead tip half of the outside circumference is white, while the body half is black.
It is only possible to use this for parts that have leads that are to be detected on two perpendicular sides or more.
Furthermore, the information for the part positioning using the lead length is not acquired so these types cannot be used for parts with leads on one side or two opposing sides only.
Example Target Parts
Type 33: Currently no example target part exists.
Type 34: PLCC parts processed with frontlighting with a white background.
