Improve Image Acquisition Speed
Network Environment Requirement
To ensure the image acquisition speed, the network environment should meet the requirements below:
The network switch, router, network interface card, and Ethernet cables in use should support gigabit bandwidth.
If the image acquisition time far exceeds the normal duration, refer to Solutions to troubleshoot the issue.
Parameter Settings
The image acquisition speed is influenced by parameter values. To further enhance the acquisition speed when it is within the normal range, adjust the parameters below:
|
After adjusting the parameter settings, ensure that the brightness of the 2D image remains appropriate and that the 3D data is complete. |
-
Adjust the parameter Exposure Mode/2D Image (Depth Source) Exposure Mode in the 2D Parameters category:
-
When the ambient light is relatively dark, it is recommended to set this parameter value to Flash.
-
When the ambient light is stable, this parameter can be set to Timed or Auto Exposure. If the parameter is set to Timed, reduce the value of Exposure Time as needed.
When the ambient light is unstable, it is recommended to set this parameter to Auto Exposure. In this mode, multiple exposures will be conducted automatically, resulting in a relatively long image acquisition time.
-
When this parameter is set to HDR, try to reduce the values of Exposure Multiplier and Exposure Time.
-
-
Adjust parameters in the 3D Parameters category:
-
Decrease the values of Exposure Multiplier and Exposure Time. If you still need to enhance the brightness of the 2D image/2D images (depth source) and improve the quality of the depth map and point cloud, increase the value of Gain as needed.
-
Set the value of Fringe Coding Mode in the Laser subcategory or the value of Fringe Coding Mode in the Projector subcategory to Fast.
-
-
Switch to the Administrator account and reduce the image resolution. The camera model and the corresponding data type, whose resolution can be adjusted, are as follows:
Model Data type LSR S and LSR L
2D image
DEEP
Depth map
After adjusting the parameters above, if you need to further enhance the image acquisition speed, switch to the Guru level and then adjust the parameters below in the 3D Parameters category:
-
If DEEP, LSR S, LSR L, Laser L, or Laser L Enhanced is in use, decrease the value of Laser Frame Partition Count in the subcategory Laser Projection Frame Control.
This parameter is unavailable when the value of Fringe Coding Mode is set to Reflective.
-
If UHP-140 is in use, set the value of Capture Mode in the UHP subcategory to Camera1 or Camera2.
-
If Laser L Enhanced or Pro L Enhanced is in use and the image quality requirement is not high, you can select the 3D Binning option.
