名称
read_bar_code_modelT_read_bar_code_modelReadBarCodeModelReadBarCodeModelread_bar_code_model — Read a bar code model from a file and create a new model.
参数签名
def read_bar_code_model(file_name: str) -> HHandle
描述
该算子 read_bar_code_modelread_bar_code_modelReadBarCodeModelReadBarCodeModelReadBarCodeModelread_bar_code_model reads the bar code model from the
file FileNameFileNameFileNameFileNamefileNamefile_name and creates a new model that is an identical copy of
the saved model. The parameter BarCodeHandleBarCodeHandleBarCodeHandleBarCodeHandlebarCodeHandlebar_code_handle returns the handle
of the new model. The model file FileNameFileNameFileNameFileNamefileNamefile_name must have been created
by 该算子 write_bar_code_modelwrite_bar_code_modelWriteBarCodeModelWriteBarCodeModelWriteBarCodeModelwrite_bar_code_model.
The default HALCON file extension for bar code model is 'bcm'.
运行信息
- 多线程类型:可重入(与非独占操作符并行运行)。
- 多线程作用域:全局(可以从任何线程调用)。
- 未经并行化处理。
This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.
