Measurement Parameters (ECM Search)
This item specifies the judgement condition for measurement results.Specify the criteria to judge the measurement result if the X and Y coordinates and the correlation with the model are OK.
- In the "Item tab" area, tap [Measurement].
- In the "Measurement condition" area, specify a value for each item.
| Set value [factory default] | |
---|
| | Specify the threshold value with which to detect candidate points in a rough search.Specify a smaller value for candidate point level when model search results are unstable. |
| | Specify the percentage to which the input image and the model image are reduced during a search.The more the image is reduced, the faster the processing becomes, but search results may be unreliable with a smaller image. |
| | Specify how many pixels should be skipped when performing a rough search. |
| | Specify how many pixels are skipped when performing a search for the "Search region". |
Important
- If you want to change measurement parameters after registering a model, it is necessary to re-register the model.
- When the setting has been changed, tap [Measure] in the "Detail" area to verify whether measurements can be made correctly.
- Set up the judgement condition.
Note - The values beside each item are measurement results of the displayed image.Take these values into consideration to determine the upper and lower limits.

| -99999.9999 to 99999.9999 | Specify the range of X-axis shifting that is judged to be OK. |
| -99999.9999 to 99999.9999 | Specify the range of Y-axis shifting that is judged to be OK. |
| | Specify the range of angles that are judged to be OK. |
Correlation value [Note 1] | | Specify the range of correlation values that are judged to be OK. |
[Note 1]: When the ECM correlation value of the measurement result is 0, the judgement result will be NG regardless of the measurement parameters setting.
