Defect Segmentation

The following parameters need to be adjusted when the defect segmentation model package is imported into this Step.

Model Package Settings

Model Manager Tool

Parameter description: This parameter is used to open the deep learning model package management tool and import the deep learning model package. The model package file is a “.dlkpack” or “.dlkpackC” file exported from Mech-DLK.

Tuning instruction: Please refer to Deep Learning Model Package Management Tool for the usage.

Model Name

Parameter description: This parameter is used to select the model package that has been imported for this Step.

Tuning instruction: Once you have imported the deep learning model by using the deep learning model package management tool, you can select the corresponding model name in the drop-down list.

DI Algo Type Translated String

Parameter description: Once a Model Name is selected, the DI Algo Type Translated String will be filled automatically.

GPU ID

Parameter description: This parameter is used to select the device ID of the GPU that will be used for the inference.

Tuning instruction: Once you have selected the model name, you can select the GPU ID in the drop-down list of this parameter.

Pre-process

ROI Path

Parameter description: This parameter is used to set or modify the ROI.

Tuning instruction: Once the deep learning model is imported, a default ROI will be applied. If you need to edit the ROI, click Open the editor. Edit the ROI in the pop-up Set ROI window, and fill in the ROI name.

Before the inference, please check whether the ROI set here is consistent with the one set in Mech-DLK. If not, the recognition result may be affected.

During the inference, the ROI set during model training, i.e. the default ROI, is usually used. If the position of the object changes in the camera’s field of view, please adjust the ROI.

If you would like to use the default ROI again, please delete the ROI file name below the Open the editor button.

Post-Process

Inference Configuration

Parameter description: This parameter is used to configure parameters related to defect segmentation model package inference. You can click Open the editor to open the inference configuration window.

Tuning instruction: Please refer to Defect Segmentation Determination Rule for the configuration instructions.

Dilation

Description: This parameter is used to increase the mask area for the deep learning algorithm. When the size of the mask is smaller than that of the target object, there will be defects in the extracted point cloud, especially the edge point cloud. Therefore, it is recommended to enable Dilation to expand the mask to avoid missing data in the extracted point cloud.

Default value: Disabled

Kernel Size

Description: This parameter is used to set the kernel size for dilation. The larger the kernel size, the stronger the dilation effect.

Default value: 3 px

Tuning recommendation: Please adjust the value according to the actual requirement after enabling Dilation.

Visualization Settings

Draw Defect Mask on Image

Parameter description: This parameter is used to determine whether to draw the defect mask on the image. If selected, a defect mask will be drawn on the input image.

Default value: Unselected.

Tuning instruction: Select to draw a mask on the input image. The figure below shows the result before and after selecting this option.

  • From Mech-Vision 1.7.2, the Defect Judgement Rules Settings, Quantity Threshold Settings, and Area Range Settings parameters are removed from the Deep Learning Model Package Inference Step. If you want to adjust these parameters, please configure them in Mech-DLK.

  • In Mech-Vision 1.7.2, when the Deep Learning Model Package Inference Step is used for inference with model packages that are exported from Mech-DLK 2.2.0 or previous versions with Defect Judgement Rules Settings configured, the old defect judgement rules will not take effect. Please configure the defect determination rules of the package model in Mech-DLK 2.4.1 or above and re-export the model package. Then, you can use the model package for inference in the Deep Learning Model Package Inference Step.
