HQV 3.0: New Variety Calibration Scan Instructions

Step by Step Instructions:

The following video will show you how to set up your calibration scans with step by step procedure written below:

Open

1. Gather and layout fruit

• Gather 20-25 pieces of fruit of varied sizes.

  • There is currently no particular criteria for the fruit to choose; but having a wide range of small, medium and large fruit is preferred to calibrate the low and high ranges.

  • If pre-sorted fruit is available it is helpful to scan sets of 20 from a small, medium and large selection and write the known sorted count size in the HQV Event notes field.

• Place fruit in a numbered grid format

  • Layout fruit in a grid with each place marked clearly in bold marker/typeface

  • Fruit should vary in the direction it faces and which side is facing up if possible

See example fruit layouts below:

2. Hand measure the fruit and and record fruit size in Croptracker.

• Hand measure the fruit in each grid and record results to using the ‘Size Calibration Inspection Template’.
  See screenshots and measurement methods examples below.
  
  

  • In the Croptracker mobile app, create an HQV Event.

    • Enter the lot code and or comments to mark this event as calibration scan set
      
      

       

    • Choose an area with matching variety and/or crop type for what is being scanned and enter a unit count and type  (i.e. 1 Bin).
      
      

       

  • Hit ‘Add Inspection’ at the bottom of the screen
    
    

  • Select ‘Size Calibration Inspection Template’
    
    

     

  • Record the size of each fruit in the corresponding grid number on the app

    • Scroll through using the arrow button at the top of the grid to add next measurments

    • *Note: you can change the number of specimens you are scanning if you have more than 25 pieces of fruit
      
      

  • Back out using arrow in top left corner of app screen when all measurements have been recorded.

Example measurement methods below: 

3. Scan Fruit in HQV event with Size Calibration Inspection Template attached.

• Hit ‘Start Scanning’ at the bottom of the HQV event

• Scan fruit in grid

  • Avoid scanning other objects or background area if possible. Using a large box or empty table surface is ideal.

  • Take several scans and rotate the fruit within it’s grid if possible.

  • Upload scans for processing.
    
    

4. Contact support@croptracker.com to notify Croptracker team of annotation scans when process is complete.

Alternate Steps 2, 3 and 4 (Not recording measurements in Croptracker)

2. Hand measure the fruit and create a spreadsheet.

• Hand measure the fruit in each grid and record results to a simple spreadsheet.

  • Note: If you are not using millimeters for measurement please make sure to indicate your actual units in the spreadsheet column headers.

  • Note: Ensuring the correct measurement aligns with the correct fruit in each grid is very important.

• Save the spreadsheet using a filename that indicates a unique Lot Number that will be used for the scan(s).

  • i.e.  If the lot was named 'Apples-Honeycrisp-May01-2020-01' could be saved as "TrainingData-Apples-Honeycrisp May01-2020-01.xls" )
    
    

3. Take the scans:

• In the Croptracker mobile app, create an HQV Event.

  • Enter the lot code that will match the spreadsheet file name you've created in Steps 1-2. 

  • Choose an area with matching variety and/or crop type for what is being scanned and enter a unit count and type  (i.e. 1 Bin).

• Scan fruit

  • Avoid scanning other objects or background area if possible. Using a large box or empty table surface is ideal.

  • Take several scans and rotate the fruit within it’s grid if possible.

4. Send notice of scans and spreadsheet to support@croptracker.com
