Taking images with Zivid Studio

Guidelines on capturing a high quality point cloud

The Capture dialog allows you to capture an image with specified settings as per requirement. You can use three modes within Zivid Studio- Grab, HDR and Live mode.

Capture dialog

Grab allows for a single capture of the objects in the camera’s field of view. 

Specify the active iris – This needs to be set according to the nature of objects you are capturing in order to get a high-quality image. If multiple iris settings are available in the window, ‘grab’ uses the highlighted setting for the capture. 

Specify exposure control- The active iris and exposure control settings go hand-in -hand to determine the amount of light that gets through. Increasing the active iris is a faster approach to achieving the desired result, but in cases where the you would like to retain depth of focus- it would be helpful to minimize the active iris and increase the exposure time instead. 
Intensity Power- This is usually set at 1.0 
Once all settings have been defined, click grab.

HDR or High Dynamic Range mode allows you to specify multiple active iris settings. An individual capture is done with each specified active iris and all the images are then combined into one HDR image for optimal results. The HDR mode is especially useful when you use colored objects or a combination of different materials. Generally, keep the number of active iris settings to a minimum, as this results in increased acquisition time and depending on the memory available on your system, could result in a time-out error.

  • Enter all the required active iris settings
  • Set the exposure time as required
  • Set intensity as required
  • Click HDR

Live mode allows you to view the cameras field of view in real time. You can specify the active iris setting to be used for the live mode.  The live mode can be especially useful when you want to determine the optimal active iris settings for an HDR capture. Click stop when you wish to exit live mode.
