The intensity image, depth map, and point cloud obtained from the laser profiler are made of multiple profiles. The quality of the profiles determines the quality of the intensity image, depth map, and point cloud. Therefore, when adjusting the parameters, you need to adjust the parameters that affect the quality of the profile first, and then adjust the parameters that only affect the quality of the intensity image, depth map, and point cloud.

Read Scanning Mechanism of Laser Profiler to familiarize yourself with the scanning mechanism of the laser profiler.

The parameters in Mech-Eye Viewer are divided into two parts:

  • Parameters in the profile mode: affect the quality of the profile.

  • Parameters in the scan mode: only affect the quality of the intensity image, depth map, and point cloud.

This topic introduces the actions related to parameters, including the general workflow of adjusting parameters, managing parameter groups, changing parameter visibility, and checking parameter descriptions.

General Workflow of Adjusting Parameters

When adjusting the parameters, you usually need to acquire the data again to check the result of parameter adjustment.

The general workflow of adjusting parameters is as follows:

workflow

  1. At the top of the Parameters tab, create a parameter group, or select a parameter group for saving the parameter values.

  2. Click Profile Mode in the upper right of the interface to switch to the profile mode.

  3. Acquire data, check the data quality, and adjust parameters.

  4. Click Scan Mode in the upper right of the interface to switch to the scan mode.

  5. Based on combination of triggering methods in use, configure the corresponding parameters.

  6. Acquire data, check the data quality, and adjust parameters.

  7. Once the data quality meets the requirements, click Save at the top of the Parameters tab.

  • If adjusting the parameters in the scan mode cannot make the data meet the requirements, please adjust the parameters in the profile mode again.

  • If the data quality is still not good, you can change the visibility and adjust the newly displayed parameters.

Manage Parameter Groups

Parameter groups are used to save parameter values for different applications, projects, workpieces, and so on. When the application, project, workpiece, etc., changes, switching the parameter group in use can quickly apply the corresponding parameter values.

In Mech-Eye Viewer, you can create a new parameter group, save parameter values to a parameter group, delete a parameter group, rename a parameter group, and import and export parameter groups.

Create a parameter group

Please follow these steps to create a parameter groups using the current parameter settings:

  1. On the right of the Parameter Group section, click icon plus.

  2. In the pop-up window, enter the name for the parameter group, and click OK.

    The parameter group name cannot be longer than 32 characters.

  3. After the parameter group is created, it will be displayed in the drop-down menu in the Parameter Group section.

Save Parameters to Parameter Group

Follow these steps to save parameters to a parameter group:

  1. Click the drop-down menu in the Parameter Group section, and select the parameter group used for saving parameter values.

  2. Adjust parameters.

  3. In the Parameter Group section, click Save or use the shortcut Ctrl + S to save the adjusted parameter values to the currently selected parameter group.

An asterisk (*) next to a parameter name indicates that the value of this parameter has not been saved to the parameter group. When the laser profiler is disconnected from power, the unsaved changes are discarded.

Delete a parameter group

To delete a no longer needed parameter group, follow these steps:

  1. Click the drop-down menu in the Parameter Group section, and select the parameter group to be deleted.

  2. Click icon reduce, and then click Yes in the pop-up window to delete the parameter group.

The default parameter group cannot be deleted.

Rename Parameter Group

Follow these steps to rename a parameter group:

  1. Click the drop-down menu in the Parameter Group section, and select the parameter group to be renamed.

  2. Click icon rename, enter the new name in the pop-up window, and then click OK.

    The parameter group name cannot be longer than 32 characters.

  3. After the change, the new name will be displayed in the drop-down menu of the Parameter Group section.

The default parameter group cannot be renamed.

Export parameter groups

You can export all the parameter groups saved in the current laser profiler to a JSON file. Follow these steps to export parameter groups:

  1. In the Parameter Group section, click Export, select the file path, and then click Save.

  2. If the parameter groups are successfully exported, the Successfully exported parameter groups window will pop-up. Click OK in the window to close this window.

Import Parameter Groups

You can import parameter groups from a JSON file to replace all the parameter groups saved in the current laser profiler. Follow these steps to import parameter groups:

  1. In the Parameter Group section, click Import, find the JSON file that stores all the parameter group information, and click Open.

  2. If the parameter groups are successfully imported, the Successfully imported parameter groups window will pop-up. Click OK in the window to close this window.

Reset Parameter Group

To reset the parameter values saved in a parameter group to default values, follow these steps:

  1. Click the drop-down menu in the Parameter Group section, and select the parameter group to be reset.

  2. Click Reset, and then click Yes in the pop-up window to reset the parameter values to those stored in the default parameter group.

Change Visibility

The visibility of parameters in Mech-Eye Viewer includes three levels: Beginner, Expert, and Guru. Select from the drop-down menu of Visibility to change the visibility.

  • The Beginner level includes the most frequently used basic parameters.

  • The Expert level includes all parameters in the Beginner level and provides more parameters.

  • The Guru level includes all parameters in the Expert level and provides more parameters.

Usually, adjusting parameters in the Beginner level is enough to meet your needs. If the data quality is still not satisfactory, you can adjust the parameters in the Expert level. In rare cases, the parameters in the Guru level need to be adjusted to meet special needs.

The Guru level is available in the Administrator account. If needed, please contact Technical Support.

Check Parameter Description

After you select a parameter in the parameter list, the bottom of the Parameters tab displays more information about this parameter, include parameter explanation, API parameter name, value range, default value, visibility and data type. When you adjust parameters, you can use the information here as a reference.

  • If the Parameter Description section blocks the parameter list, click × at the upper right of this section to close it.

  • To display the Parameter Description section again, check the Parameter Description option in the View menu.
