get_image_size (Image, Width, Height)zoom_image_factor(Image,ZooImage,0.5, 0.5, 'bilinear')*功能:按给定因子缩放图像*参数1:原图像*参数2:缩放后保存的图像*参数3:图像宽度的比例因子,默认值:0.5建议值:0.25,0.5,1.5,2.0* 典型值范围:0.001≤ 横向≤10最小增量:0.001建议增量:0.1*参数4:图像高度的比...
1. 使用 zoom_image_factor 进行缩放 zoom_image_factor 允许你根据指定的缩放比例因子对图像进行缩放。 python * 读取图像 read_image(Image, 'path_to_image_file') * 获取图像尺寸(如果需要) get_image_size(Image, Width, Height) * 设置缩放因子 ScaleFactorX := 0.5 ScaleFactorY := 0.5 * 执行缩放...
在QtCreator中 HObject ho_Image1, ho_ZooImage; HTuple hv_Width, hv_Height, hv_Width1, hv_Height1; ReadImage(&ho_Image1, "D:/bb/tu/ma.jpg"); GetImageSize(ho_Image1, &hv_Width, &hv_Height); ZoomImageFactor(ho_Image1, &ho_ZooImage, 0.5, 0.5, "bilinear"); //功能:按给定因子...
zoom_image_factor (Image, ImageZoomed,0.125,0.125,'constant') 以上1行代码,等效以下三行。 *每层为原来1/2,得到9层金字塔,第9层是1×1gen_gauss_pyramid (Image, ImagePyramid,'constant',0.5)*查看有多少层 count_obj (ImagePyramid, Number)*获取第4层,即原图的1/8select_obj (ImagePyramd, ObjectS...
zoom_image_factor scales the image Image by a factor of ScaleWidth in width and a factor ScaleHeight in height. The parameter Interpolation determines the type of interpolation used (see affine_trans_image). The domain of the input image is ignored, i.e., assumed to be the full rectangle...

zoom_image_factor(Image : ImageZoomed : ScaleWidth, ScaleHeight, Interpolation : ) 1. 图像裁剪: halcon裁剪可以通过reduce_domain()来实现,但是它得到的只是图像的数据类型需要通write_image()来实现保存。同时,值得注意的是,通过相关方式保存的的图像大小实际上和原图大小一样,所以可以采用paint_region()的方...
zoom_image_factor(ImageSub,ImageZoomed,ScaleFactor,ScaleFactor,'constant') *获取变焦后的图像的ROI get_domain(ImageZoomed,Domain) *图像ROI进行腐蚀操作 erosion_rectangle1(Domain,RegionErosion,7,7) *获取变焦图像中ROI区域内的图像 reduce_domain(ImageZoomed,RegionErosion,ImageReduced) ...
sub_image (Image, ImageFFT1, ImageSub, 5, 100) *对图像进行缩放,一般图像特别大的时候,缩放一下,提取效果会更好 zoom_image_factor (ImageSub, ImageZoomed, 0.4, 0.4, 'constant') *将图像中的有灰度差异的线条提取出来 lines_gauss (ImageZoomed, Lines1, 0.2, 3, 8, 'light'...
zoom_image_factor (ImageSub, ImageZoomed, 0.4, 0.4, 'constant') *将图像中的有灰度差异的线条提取出来 lines_gauss (ImageZoomed, Lines1, 0.2, 3, 8, 'light', 'true', 'gaussian', 'true') 注:当图像质量不理想时,提取线条的效果不好时,不妨试试这种方法,亲测效果很好。
