关于MVTec HALCON图像识别更跟-　Purpose:

　This example program shows the use of pattern matching with shape models

　to locate an object.　Furthermore, it shows how to use the detected position

　and rotation of the object to construct search spaces for inspection tasks.

　In this particular example, the print on an IC is used to find the IC.　From

　the found position and rotation, two measurement rectangles are constructed

　to measure the spacing between the leads of the IC.　Because of the lighting

　used in this example, the leads have the saturated gray value of 255 at

　several positions and rotations, which enlarges the apparent width of the

　leads, and hence seems to reduce the spacing between the leads, although the

　same board is used in all images.
