Use Mech-Eye Viewer to Adjust Camera Parameters for GenICam Client

You are viewing an old version of the documentation. You can switch to the documentation of the latest version by clicking the top-right corner of the page.

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:

  1. Save the changes that you made in the GenICam client.

  2. Disconnect from the camera in the GenICam client.

  3. Connect to the camera in Mech-Eye Viewer.

  4. In the parameter panel 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 with Visualized Tools

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:

  1. In the parameter panel on the right of Mech-Eye Viewer, locate the 2D Parameters category.

  2. From the drop-down menu of Exposure Mode, select Auto.

  3. Double-click Edit to the right of Auto-Exposure ROI to open the Set ROI window.

  4. 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:

  1. In the parameter panel on the right of Mech-Eye Viewer, locate the Depth Range category.

  2. Double-click Edit to the right of Depth Range to open the Set Depth Range window.

  3. 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:

  1. In the parameter panel on the right of Mech-Eye Viewer, locate the ROI category.

  2. Double-click Edit to the right of ROI to open the Set ROI window.

  3. 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.

  1. In the parameter panel 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.

  2. Disconnect from the camera in Mech-Eye Viewer.

  3. Connect to the camera in the GenICam client.

  4. In the GenICam client, select and load the parameter group with the UserSetSelector and UserSetLoad parameters.
