如下是model:
如下是采样图片
以下是程序运行结果:
以下是代码的逐行解释:
dev_update_off():关闭设备更新,以提高处理速度。
read_image (ModelImage, ‘food/cocoa_package_model’):读取模型图像。
dev_close_window ():关闭当前窗口。
dev_open_window_fit_image (ModelImage, , , -1, -1, WindowHandle):打开一个窗口,窗口大小自动调整以适应图像。
set_display_font (WindowHandle, 16, ‘mono’, ‘true’, ‘false’):设置窗口的显示字体。
创建并显示局部可变形模型:
create_local_deformable_model:创建一个局部可变形模型。
get_deformable_model_contours:获取模型的轮廓。
area_center:获取图像的中心点。
hom_mat2d_identity 和 hom_mat2d_translate:创建一个平移矩阵,将模型轮廓平移到图像中心。
affine_trans_contour_xld:使用平移矩阵变换模型轮廓。
dev_set_line_width (2):设置线条宽度为2。
dev_set_color (‘yellow’):设置线条颜色为黄色。
dev_display (ModelImage):显示模型图像。
dev_display (ContoursAffinTrans):显示变换后的模型轮廓。
disp_message:在窗口中显示消息。
disp_continue_message:在窗口中持续显示消息。
stop ():暂停执行。
循环搜索图像:
read_image:读取要搜索的图像。
dev_resize_window_fit_image:调整窗口大小以适应图像。
dev_display:显示图像。
disp_message:显示搜索消息。
count_seconds:计算搜索开始时间。
find_local_deformable_model:在图像中搜索局部可变形模型。
count_seconds:计算搜索结束时间。
Time := S2 - S1:计算搜索时间。
gen_warped_mesh:生成变形网格。
dev_display:显示变形网格。
Found[Index] := |Score|:记录搜索得分。
disp_message:显示搜索结果。
if (Index < NumImages):如果还有图像未搜索,显示继续消息并暂停。
clear_deformable_model (ModelID):清除局部可变形模型。
这个脚本的主要功能是创建一个局部可变形模型,并在一系列图像中搜索这个模型,然后显示搜索结果和搜索时间。
