C++ Halcon识别条形码示例

//初始化模型
CreateBarCodeModel(HTuple(), HTuple(), &hv_BarCodeHandle);
//设置最小对象面积大小
SetBarCodeParam(hv_BarCodeHandle, "element_size_min", 3200);
//设置校验开启
SetBarCodeParam(hv_BarCodeHandle, "check_char", "present");
//设置只识别一个
SetBarCodeParam(hv_BarCodeHandle, "stop_after_result_num", 1);
// Local iconic variables

// Local control variables
