Increase Data Acquisition Speed
Network Environment Requirement
To ensure the data 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.

When using Range XL-GL, also observe the following:

If the data acquisition time far exceeds the normal duration, refer to Solutions to troubleshoot the issue.
Parameter Settings
The data acquisition speed is influenced by parameter values. Adjust the parameters below to further enhance the data acquisition speed.
After adjusting the parameter settings, ensure that the brightness of the 2D image remains appropriate and that the depth data is complete.
-
Adjust the parameter Exposure Mode in the 2D Parameters category or Exposure Mode in the 2D Image (Depth Source) subcategory:
-
When the ambient light is dark, it is recommended to set this parameter value to Flash.
If Flash Acquisition Mode is displayed, set its value to Fast. If Flash Acquisition Mode is set to Responsive, decrease the value of Flash Exposure Time.
-
When the ambient light is stable, this parameter can be set to Timed or Auto. If the parameter is set to Timed, decrease the value of Exposure Time.
When the ambient light is unstable, it is recommended to set this parameter to Auto. In this mode, multiple exposures will be conducted automatically, resulting in a relatively long image acquisition time.
-
When this parameter is set to HDR, decrease 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 there is depth map and point cloud loss, you can increase the gain.
-
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. Camera models whose resolutions can be changed are as follows:
-
LSR S-GL, LSR L-GL, LSR XL-GL: The resolution of the 2D image can be changed.
-
DEEP-GL: The resolution of the depth map can be changed.
-
NANO ULTRA-GL, PRO S-GL, and PRO M-GL: Both the resolutions of the 2D image and depth map can be changed.
-
-
If DEEP-GL, LSR S-GL, LSR L-GL, LSR XL-GL or UHP-140-GL is in use, you can also switch to the guru level, and adjust the parameters in the 3D Parameters category according to the table below to further enhance the acquisition speed.
Model Parameter UHP-140-GL
Set the value of Capture Mode in the UHP subcategory to Camera1 or Camera2.
DEEP-GL, LSR S-GL, LSR L-GL, and LSR XL-GL
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.
-
When using Range XL-GL, adjust the parameters in the Data Output Type group:
-
Select Data Output Type according to your needs. If you do not need a 2D image, select Point cloud.
-
Decrease 3D Exposure Time. If parts of the depth map or point cloud are missing, increase 3D Gain as needed.
-
Decrease Scan Time. A shorter scan time reduces acquisition time but produces a sparser point cloud. If the point cloud is too sparse, adjust Depth Range as needed. A narrower depth range produces a denser point cloud at the same scan time. Set Scan Time and Depth Range to balance acquisition efficiency and point cloud quality.
-
When Data Output Type is set to 2D image or 2D image (texture), decrease 2D Exposure Time. If the image is too dark, turn on the Enable 2D Illumination parameter or increase 2D Gain before extending the exposure time.
-
When Data Output Type is set to Point cloud + 2D image (texture), decrease 2D Exposure Time. If the 2D image is too dark, turn on the Enable 2D Illumination parameter before extending the exposure time.
