FH/FZ5 Processing Item Function Reference Manual
Shape Search II
This function is for detecting user-defined target to estimate target position and pose precisely. The correlation
value indicating the degree of similarity, measurement target position, and orientation can be output.
In shape search II, edge information is used as features, whe
r
eas in a normal search mode, color and texture
information are used.
Since state-of-the-art object dete
c
tion algorithm is exploited in shape search III, it can provides much more
reliable position and pose estimation with higher speed compared to shape search II. Furthermore, it has much
more parameter to tune to support a wider variety of applications.
Used in the Following Case
• Alignment mark detection and precise position estimation.
• Processing is different for color images and monochrome images. If the camera type, color camera, or monochrome
camera, was changed from a previous setup, a reset of some settings may be needed.
• Search processing basic concepts
