Halcon学习之八:图像区域叠加与绘制

overpaint_gray ( ImageDestination, ImageSource : : : )

将灰度值不相同区域用不同颜色绘制到ImageDestination中, ImageSource包含希望的灰度值图像

overpaint_region ( Image, Region : : Grayval, Type : )

Region以一个恒定的灰度值绘制到Image图像中

paint_gray ( ImageSource, ImageDestination : MixedImage : : )

ImageSource的图像绘制到ImageDestination中,形成MixedImage

paint_region ( Region, Image : ImageResult : Grayval, Type : )

Region以一个恒定的灰度值绘制到Image图像中

paint_xld ( XLD, Image : ImageResult : Grayval : )

XLD以一个恒定的灰度值绘制到Image图像中

set_grayval ( Image : : Row, Column, Grayval : )

设置Image图像中坐标为(RowColumn)的灰度值

 

程序:

 

read_image (Image, 'G:/Halcon/images/images/claudia.png') gen_circle (Circle, 200, 200, 100.5) reduce_domain (Image, Circle, ImageReduced) gen_image_proto (Image, ImageCleared, 32) overpaint_gray (ImageCleared, ImageReduced) gen_image_const (Image1, 'byte', 512, 512) overpaint_region (Image1, Circle, 255, 'fill') * /* Copy a circular part of the image into the image : */ read_image (Image2, 'G:/Halcon/images/images/brycecanyon1.png') paint_gray (ImageReduced, Image2, MixedImage) * /* Paint a rectangle into the image */ read_image (Image3, 'G:/Halcon/images/images/pads.png') gen_rectangle1 (Rectangle1, 30, 20, 100, 200) paint_region (Rectangle1, Image3, ImageResult, 255, 'fill') * /* Paint colored xld objects into a gray image */ * /* read and copy image to generate a three channel image */ copy_image (Image2, image0) copy_image (Image2, image1) compose3 (image0, Image2, image1, MultiChannelImage) * /* extract subpixel border */ threshold_sub_pix (MultiChannelImage, Border, 128) * /* select the circle and the arrows */ circle := Border[14] arrow := Border[16] ObjectsConcat := [circle,arrow] * /* paint a green circle and white arrows (to paint all * * objects e.g. blue, pass [0,0,255] tuple for GrayVal) */ paint_xld (ObjectsConcat, MultiChannelImage, ImageResult1, [0,1,0,1,1,255])
