Angle Range: it means the angle changing range when comparing the target and created
template. If you want to search the proactive target, and then you need to set respectively, and the
default range is -90° to 90°.
Scale Range: it means scale changing range when comparing the target and created
template. If you want to search the target with same scale changing, and then you need to set
respectively, and the default range is 1.0 to 1.0.
(2) Advanced Parameters
Location Type: direct mapping and secondary correction can be selected. Direct mapping
takes short time, low precision, and secondary correction takes long time and high precision.
Max. Overlap Threshold: when searching for multiple targets, two detected targets
overlapping with each other, and the maximum overlap ratio allowed by the matching frames is
overlap threshold. The larger the value, the greater the degree of overlapping between the two targets.
The range is 0 to 100 and it is 50 by default.
Sort:
- Sort by score in descending order: sorted by the score of the feature match
in descending order.
- Sort by angle in descending order: in descending order of relative angular
deviation in the current result.
- Sort by X from small to large: the current result has the X coordinate of the
matching box center. According to the X coordinate, the order is rounded up
from small to large. When the X coordinates are the same, then is sorted by
Y from big to small, and the Y axis has the same operation with X axis.
- X is from small to large, and Y is from small to large too: the current result
has the matching box center X/Y coordinates. According to the X coordinate,
the order is rounded up from small to large. When the X coordinates are the
same, then the order is sorted according to Y from small to large.
Threshold Type:
- Automatic threshold: it automatically determines the threshold parameter
according to the target image.
- Template threshold: it uses the contrast threshold of the template as the
contrast threshold in matching phase.
- Manual threshold: it uses the threshold set by the user as the threshold
parameter for searching.
Clutter Considered: If mottle considered is enabled, the algorithm will consider the mottle
feature. If the feature has burrs, the score will decrease.
Extension Threshold: please refer to the configured parameters of feature matching.
Timeout Control: When the time exceeds the time set by the overtime control, the search
will stop and no search result will be returned. The value range of overtime control is 0 ms to 10000
ms, and 0 means that the overtime control is disabled.
