Adjust Parameters
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:
-
At the top of the Parameters tab, create a parameter group, or select a parameter group for saving the parameter values.
-
Click Profile Mode in the upper right of the interface to switch to the profile mode.
-
Acquire data, check the data quality, and adjust parameters.
-
Click Scan Mode in the upper right of the interface to switch to the scan mode.
-
Based on combination of triggering methods in use, configure the corresponding parameters.
-
Acquire data, check the data quality, and adjust parameters.
-
Once the data quality meets the requirements, click Save at the top of the Parameters tab.

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, reset a parameter group, and import and export parameter groups.
Create Parameter Group
Please follow these steps to create a parameter groups using the current parameter settings:
-
On the right of the Parameter Group section, click +.
-
In the pop-up window, enter the name for the parameter group, select an appropriate template, and click Create.
The parameter group name cannot be longer than 99 characters. -
After the parameter group is created, it takes effect immediately.
Save Parameters to Parameter Group
Follow these steps to save parameters to a parameter group:
-
Click the drop-down menu in the Parameter Group section, and select the parameter group used for saving parameter values.
-
In the Parameter Group section, click the Save button 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 Parameter Group
To delete a no longer needed parameter group, follow these steps:
-
In the Parameter Group section, click
to open the Manage Parameter Group window. -
Click
on the right side of the parameter group to be deleted, and click Confirm to delete the parameter group.-
The default and calib parameter groups cannot be deleted.
-
To delete multiple parameter groups, select the parameter groups to be deleted, click the Delete selected button in the upper right corner of the window, and click Confirm.
-
Rename Parameter Group
Follow these steps to rename a parameter group:
-
In the Parameter Group section, click
to open the Manage Parameter Group window. -
Click
on the right side of the parameter group to be renamed, enter the new name in the text box, and click the area outside the text box. The new name is confirmed and saved.The parameter group name cannot be longer than 99 characters. -
After the change, the new name will be displayed in the drop-down menu of the Parameter Group section.
The default and calib parameter groups cannot be renamed.
Reset Parameter Group
To reset the parameter values saved in a parameter group to default values, follow these steps:
-
Click the drop-down menu in the Parameter Group section, and select the parameter group to be reset.
-
Click the Reset button, and then click Confirm in the pop-up window to reset the parameter values in the parameter group.
-
If the parameter group is created based on a parameter group template, the parameter values will be reset to the values stored in the template.
-
If the parameter group is created based on the current parameter group, the parameter values will be reset to the default values.
-
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:
-
In the Parameter Group section, click Import, find the JSON file that stores all the parameter group information, and click Open.
-
If the parameter groups are successfully imported, the Successfully imported parameter groups window will pop-up. Click Confirm in the window to close this window.
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:
-
In the Parameter Group section, click Export, select the file path, and then click Save.
-
If the parameter groups are successfully exported, the Successfully exported parameter groups window will pop-up. Click Confirm in the window to close this window.
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.
