def read_bar_code_model(file_name: str) -> HHandle
描述
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 the operator write_bar_code_modelwrite_bar_code_modelWriteBarCodeModelWriteBarCodeModelWriteBarCodeModelwrite_bar_code_model。The default HALCON file extension for bar code model is 'bcm'.
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
此算子返回一个句柄。请注意，即使该句柄被用作特定算子的输入参数，这些算子仍可能改变此句柄类型的实例状态。
