Overview

The Intel® RealSense™ Viewer tool supports several predefined depth presets that can be selected according to the user's usage. The predefined presets are listed in the table below. The table explains some of the recommended use cases for each predefined preset. There are also examples of images with each preset and a corresponding JSON file.
The user can also modify the settings via the Advanced Mode menu and save a customized user preset. All the settings can be saved and loaded via the tool's menu. We use machine learning algorithms and capture of ground truth datasets to optimize preset for certain conditions, and we may add more presets in the future. The developers can do this too, or just start adjusting the parameters by hand, but we do not provide guidance on this. The key to good depth is to start from our recommended defaults:

  • D435: Use 848x480 resolution @30fps, with auto-exposure. Use post processing with downsample 2.
  • D415: Use 1280x720 resolution @30fps, with auto-exposure. Use post processing with downsample 3.

If you have bad depth, please first try to use manual exposure and adjust exposure. Keep gain as low as possible (preferably 16).

For further information, please refer to "Best Known Methods for Tuning Intel RealSense Depth Cameras D415 and D435" at https://realsense.intel.com/intel-realsense-downloads/#whitepaper.

Supported Devices

Please refer to latest release for the supported devices and platforms.

Preset Table

Note: Some of the presets are different based on the resolution and some are the same for all resolutions. The resolution range is:

  • High Res - 1280x720 or 848x480
  • Med Res - 640x480 or 640x360
  • Low Res - 480x270 or 424x240
Resolution \ Preset Use Cases recommended for usage Resolution Based? JSON files
High Density Higher Fill factor, sees more objects. (Ex. BGS and 3D Enhanced Photography, Object recognition) Yes HighResHighDensityPreset.json, MedResHighDensityPreset.json, LowResHighDensityPreset.json
Medium Density Balance between Fill factor and accuracy. Yes HighResMedDensityPreset.json, MedResMedDensityPreset.json, LowResMedDensityPreset.json
High Accuracy High confidence threshold value of depth, lower fill factor. (Ex. Object Scanning, Collision Avoidance, Robots) Yes HighResHighAccuracyPreset.json, MedResHighAccuracyPreset.json, LowResHighAccuracyPreset.json
Hand Good for Hand Tracking, Gesture recognition, good edges No HandGesturePreset.json
Left Imager Color w/o IR Pattern Removes the Projector-generated IR pattern from left imager when streaming synthetic RGB.
Applies to D415 and D410 Devices.
Supported since FW ver 5.9.10+
No D415_RemoveIR.json
Default Best Visual appeal, Clean edges, Reduced PointCloud Spraying No DefaultPreset_D415.json, DefaultPreset_D435.json

Example Pictures

Please refer to the example pictures below captured with the various presets. The depth presets are evaluated and compared based on:

  • Depth quality based on a 3D scene configured to include a variety of object types, textures, and distances.
  • A flat target depth metric test

All pictures were taken with these settings/conditions:

  • Resolution: 1280 x 720
  • Frame Rate: 30
  • Auto Exposure: On
  • Ambient fluorescent lighting (~100 - 200 lx)

RGB Images

The following RGB images captured as a test scene with objects ranging from ~0.6m (foreground cube and hand) to ~2m (back wall) from camera.
