Embodiment Construction
[0031] refer to Figure 1-7 . The specific steps of the online multi-stroke axonometric sketch clustering method based on the regional common boundary of the present invention are as follows:
[0032]Step 1: Obtain the closed area of the sketch and its boundary tolerance zone based on image processing technology, which is divided into three steps:
[0033] Step 1.1: Use the existing segmentation method based on the trapped ball to extract the closed area of the sketch, and the initial radius of the trapped ball is 8 pixels.
[0034] Step 1.2: Carry out the processes of dilation, erosion and the difference between the two in turn for each sketch area, and obtain the annular tolerance band surrounding the border of the sketch area, referred to as the area boundary band, whose width is l r The radius m of the minor axis of the ellipse circumscribing the region r Depends on: α is the empirical coefficient, take 1.1.
[0035] Step 1.3: First, use a circular structural ele...
