签名

create_metrology_model( : : : MetrologyHandle)

描述

create_metrology_modelcreate_metrology_modelCreateMetrologyModelCreateMetrologyModelCreateMetrologyModelcreate_metrology_model creates a metrology model, i.e., the data structure that is needed to measure objects with a specific geometric shape (metrology object) via 2D metrology, and returns it in the handle MetrologyHandleMetrologyHandleMetrologyHandleMetrologyHandlemetrologyHandlemetrology_handle。

注意

Note, that after calling the operator create_metrology_modelcreate_metrology_modelCreateMetrologyModelCreateMetrologyModelCreateMetrologyModelcreate_metrology_model the operator set_metrology_model_image_sizeset_metrology_model_image_sizeSetMetrologyModelImageSizeSetMetrologyModelImageSizeSetMetrologyModelImageSizeset_metrology_model_image_size should be called for efficiency reasons.

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。

参数

计量模型的句柄。

示例（HDevelop）

read_image (Image, 'fabrik')
create_metrology_model (MetrologyHandle)
get_image_size (Image, Width, Height)
set_metrology_model_image_size (MetrologyHandle, Width, Height)
add_metrology_object_rectangle2_measure (MetrologyHandle, 270, 230, 0, 30, \
                                  25, 10, 2, 1, 30, [], [], Index)
apply_metrology_model (Image, MetrologyHandle)
get_metrology_object_result (MetrologyHandle, Index, 'all', 'result_type', \
                      'all_param', Rectangle)
get_metrology_object_result_contour (Contour, MetrologyHandle, \
                                    Index, 'all', 1.5)

结果

如果参数有效，算子 create_metrology_modelcreate_metrology_modelCreateMetrologyModelCreateMetrologyModelCreateMetrologyModelcreate_metrology_model 返回值 2 (H_MSG_TRUE)。如有必要，则抛出异常。
