System Settings​

Overview​

SymphonyVision has many customizable settings to modify how the SymphonyVision sensor detects, reacts, and snapshots weed and crop presence.

Vision Sensor Settings​

Location Vision Sensor

The following Vision Sensor Settings can be modified:

  1. Target Width - Minimum spray applied width based on distance from weed. (parallel to boom) Effectively, this setting adjusts how many nozzles will spray when a weed is detected.
    • Extra Small - 1 nozzle minimum, 10" on either side of weed, only for testing or demo / not for use in-field
    • Small - 2 Nozzles minimum, 20" on either side of weed, not recommended
    • Medium - 3 Nozzles minimum, 30" on either side of weed, recommended setting
    • Large - 5 Nozles minimum, 40" on either side of weed, very cautious setting

Target Width

:::Note The minimum nozzles is an indication of the absolute minimum number of nozzles that will always spray on a particular setting when weeds are detected, in many situations, there will be +1 nozzle spraying due to actual location of weed in relation to nozzles. This is also based on 20" spacing as well.
:::

  1. Target Length - Minimum spray applied length based on distance from weed. (perpendicular to boom) Effectively, this setting adjusts the distance the nozzles will start and stop spraying before and after the weed when a weed is detected.
    • Extra Small - 1 nozzle minimum, 12" before and after the weed, only for testing or demo / not for use in-field
    • Small - 2 Nozzles minimum, 20" before and after the weed, not recommended
    • Medium - 3 Nozzles minimum, 40" before and after the weed, recommended setting
    • Large - 5 Nozzles minimum, 60" before and after the weed, very cautious setting

Target Length

  1. Detection Sensitivity - Adjusts the weed detection threshold that determines when a spray application reaction will be commanded. The spray application reaction is determined by the severity and control settings.
    • low - Less likely to adjust spray application / more savings
    • Medium - Recommended
    • High - More likely to adjust spray application / less savings
    • Custom

Target Length

  1. Crop Present - If spraying in a compatible crop, can be enabled for green on green spraying. Check compatibility list for current crop compatibility.
    • Enable - Checks the active crop in the Field Settings and will enable green on green spraying in that crop if currently compatible. Any crop that is not currently active, will be sprayed as a weed.
    • Disable - Disable for green on brown conditions, will detect all plants as a weed.
info

Weed Severity is the control metric used by the SymphonyVision system. This is a combined value of weed density (number of weeds) and weed size (height and width) of weeds in an area. The following settings allow the operator to dial in density and height settings for their specific conditions. These settings affect the control metric that informs application adjustments in the Weed Severity Control settings.

  1. Low Severity Max Density - This is the maximum density percentage that the sensor will consider a Low Severity.
info

For example, if the percentage is set at 25%, any weed density detected at 25% or less will be considered Low Severity for spray application adjustment.

  1. Medium Severity Max Density - This is the maximum density percentage that the sensor will consider a Medium Severity.
info

Continuing the above example, if this percentage value is set to 40%, any weed density detected between 25%-40% will be considered Medium Severity for spray application adjustment.

  1. Low Severity Max Height - This is the Maxmimum height in inches that the sensor will consider a Low Severity.
info

For example, if the height is set at 4", any weed height detected 4" or less will be considered Low Severity for spray application adjustment.

  1. Medium Severity Max Height - This is the Maximum height in inches that the sensor will consider a Medium Severity.
info

Continuing the above example, if this height is set to 8", any weed density detected betweeen 4" and 8" will be considered Medium Severity for spray application adjustment.

important

Weed Severity rating will adjust based on the metric with the highest rating at any given time. So from both of our examples, if the weed height is detected at 3", but the density is detected at 35%, our Weed Severity rating will be Medium.

  1. Weed Density Photos Enabled - Enable or disable the ability to snapshot based off of a Weed Density threshold.
  2. Weed Density Threshold - The threshold that must be met in order for a snapshot to be taken based on Weed Density
  3. Crop Health Triggered Photos - Enable or disable the ability to snapshot based off of a Crop Health threshold.
  4. Crop Health Threshold - The threshold that must be met in order for a snapshot to be taken based on Crop Health

Vision Photo Controller Settings​

The following Vision Photo Controller settings can be modified:

  1. Button Triggered Photos - enable or disable snapshots that can be manually taken from a widget on the homescreen.
  2. Distance Triggered Photos - enable or disable snapshots based on distance thresholds.
  3. Automatic Distance-Based Photo Interval - Set the distance interval for Distance Triggered Photos (it is recommended to keep this distance to 5000')
  4. Minimum Distance Between Threshold Photos - When a Weed Density or Crop Health threshold snapshot is taken, this distance is the "rest time" before another threshold snapshot can be taken again.
tip

For any triggered snapshots, it is recommended to only enable 1-3 cameras across the boom to keep snapshot data useful in Panorama. Be aware of the camera locations when assigning a trigger mode.

important

For best value of the scouting functionality, it is recommended to have in-cab internet connectivity (via hotspot, etc) and linked to their Panorama account.

Home Screen​

For SymphonyVision, the Home Screen displays scouting data for weeds and crops in an easy to read and navigate format. This information is presented as both metrics and high-definition maps. Additional screen configurations may be added and customized with different metrics, widgets, map sizes, controls, and minicharts. Screen configurations mya be toggled between by pressing the arrows at the top of the screen.

-image of homescreen w/ vision widgets-

The 20|20 displays high definition real-time maps while operating. Different map layers may be selected and viewed during operation.

Map Layers​

Different maps are available for the SymphonyVision System. To view the map layer options, press the current layer name displayed in the top left corner of the map. A list of all available maps will be displayed.

SymphonyVision Map Metrics

  • Weed Severity - The control metric, displays a combined value of weed density and size (height and width) of weeds in an area.
    • None - no weeds are detected
    • Low - Determined by the Severity settings in the Vision Controller System
    • Medium - Determined by the Severity settings in the Vision Controller System
    • High - Determined by the Severity settings in the Vision Controller System
    • Unknown - indicates no determination could be made

Weed Severity

  • Weed Density - Percentage value based on the number of weeds
  • Weed Type - Displays weed identification as either
    • Broadleaf
    • Grass
    • Broadleaf and Grass
    • Emerging - This is a plant that is too small to be accurately identified as a crop or weed.
    • None
    • Unknown - indicates no determination could be made
  • Nozzle Height - Height of nozzles in inches

Metric Widgets​

Different widgets are available for the SymphonyVision System. To view the widget options, press the 4 squares in the top left of the Home Screen. In the bottom right, press Add Widget button. For detailed information on adding widgets please see the 20|20 Operator's guide.

  • Weed Density - Percentage value based on the number of weeds
  • Nozzle Height - Height of nozzles in inches

Control Widgets​

Control Widgets may be added to the Home Screen in order to give control of some aspect of the product.

  • Capture Photos - Allows the operator to capture a photo on any cameras that have manual snapshot enabled.
tip

For green on green conditions, it is also recommended to have the ==Active Field== control widget on the homescreen for a quick verification of crop type set for the field.
