Use Mech-Eye Viewer to Adjust Camera Parameters for GenICam Client
Setting camera parameters such as Auto-Exposure ROI, Depth Range and ROI usually requires the assistance of visualized tools for several rounds of fine tuning. Since GenICam-compliant third-party machine vision software (GenICam clients) does not provide visualized tools, you can set these parameters by using the visualized tools provided in Mech-Eye Viewer.
After setting these parameters using Mech-Eye Viewer, you can read the latest camera configuration in a GenICam client directly.
Preparation
Before you adjust parameters in Mech-Eye Viewer, complete the following steps:
-
Save the changes that you made in the GenICam client.
-
Disconnect from the camera in the GenICam client.
-
In the Parameters tab on the right of Mech-Eye Viewer, select the parameter group to which you want to save the parameter values.
| A GenICam client can read parameter groups but not add or delete parameter groups. For instructions on adding/deleting a parameter group, please refer to Configure Parameter Group in Mech-Eye Viewer. |
Adjust Parameters
Below you can find instructions on setting Auto-Exposure ROI, Depth Range and ROI, respectively.
Set Auto-Exposure ROI
To set Auto-Exposure ROI, follow these steps:
-
In the Parameters tab on the right of Mech-Eye Viewer, locate the 2D Parameters category.
-
From the drop-down menu of Exposure Mode, select Auto.
-
Double-click Edit to the right of Auto-Exposure ROI to open the Set ROI window.
-
Set Auto-Exposure ROI in the pop-up window. For detailed instructions, please refer to Set Auto-Exposure ROI. The correspondence between Auto-Exposure ROI parameters in a GenICam client and those in Mech-Eye Viewer is as follows:
| Parameter in GenICam Client | Parameter in Mech-Eye Viewer |
|---|---|
Scan2DROILeft |
Upper-left coordinates: x |
Scan2DROITop |
Upper-left coordinates: y |
Scan2DROIHeight |
Dimensions: Height |
Scan2DROIWidth |
Dimensions: Width |
Set Depth Range
To set Depth Range, follow these steps:
-
In the Parameters tab on the right of Mech-Eye Viewer, locate the Depth Range category.
-
Double-click Edit to the right of Depth Range to open the Set Depth Range window.
-
Set Depth Range in the pop-up window. For detailed instructions, please refer to Set Depth Range.
The correspondence between Depth Range parameters in a GenICam client and those in Mech-Eye Viewer is as follows:
| Parameter in GenICam Client | Parameter in Mech-Eye Viewer |
|---|---|
DepthLowerLimit |
Depth Range: Depth Lower Limit |
DepthUpperLimit |
Depth Range: Depth Upper Limit |
Set ROI
To set ROI, follow these steps:
-
In the Parameters tab on the right of Mech-Eye Viewer, locate the ROI category.
-
Double-click Edit to the right of ROI to open the Set ROI window.
-
Set ROI in the pop-up window. For detailed instructions, please refer to Set ROI.
The correspondence between ROI parameters in a GenICam client and those in Mech-Eye Viewer is as follows:
| Parameter in GenICam Client | Parameter in Mech-Eye Viewer |
|---|---|
Scan3DROILeft |
Upper-left coordinates: x |
Scan3DROITop |
Upper-left coordinates: y |
Scan3DROIHeight |
Dimensions: Height |
Scan3DROIWidth |
Dimensions: Width |
Read Altered Values into GenICam Client
After setting Auto-Exposure ROI, Depth Range and ROI in Mech-Eye Viewer, complete the following steps to ensure that the GenICam client can read the modified parameter values.
-
In the Parameters tab on the right of Mech-Eye Viewer, click Save at the top or press Ctrl + S on the keyboard to save the parameter values into the parameter group.
-
Disconnect from the camera in Mech-Eye Viewer.
-
Connect to the camera in the GenICam client.
-
In the GenICam client, select and load the parameter group with the UserSetSelector and UserSetLoad parameters.
