This document contains a how-to step by step guide on how to upload HQV scans and view results on the Croptracker mobile app.

You will need the Harvest Quality Vision module to access this feature.

For more information on adding Harvest Quality Vision to your Croptracker account contact support@croptracker.com

Important Notes:

To view results, your device must be connected to Wi-Fi or Data.

The Croptracker app must be open and displayed in order for data to be uploaded. Do not switch apps or close Croptracker when awaiting results as it will pause the upload process.

The screen of your device must not go to sleep while uploading. If you are uploading many results at once, changing your device settings to turn off the screen saver is advised.

When uploading many scans at once, the upload process may take longer than expected. Each scan can take about a minute to upload, so if there are hundreds of scans being uploaded at the end of the day, it could take hours. Please plug in your device and keep Croptracker open to ensure all scans upload as expected.

As long as the bar at the top is orange, the app is uploading data. This data can be scans as well as any other data points entered into the app. If it is taking a long time that usually means it is uploading scans - this is normal.

If you are having issues accessing, uploading, or viewing results after these troubleshooting steps, please contact support@croptracker.com

  Instructions

1. When you have finished creating an HQV event and capturing the desired scans, hold and pull down on either the HQV Events screen or the HQV event list as pictured below. This will send the scans up to the cloud for processing.

See How to Set Up a Harvest Quality Vision Event for a detailed guide on creating an HQV event.

 

 

2. When the scans have been processed, size and color results will display with its associated Harvest Quality Vision Event.

 

3. Size Results will be displayed in 5mm size bands on the app by default. The number of fruit detected (AKA the number of fruit included in the results) will be displayed at the top.

 

4. The size bands can now be changed to any increment between 1 to 5 mm. Simply select the option for Size Band.

 

5. After selecting the Size Band option, you will see a list of size bands to choose from. Select the one you wish to use and you will be returned to the HQV event page with the new size band.

 

6. To change the size results view to a custom size class range, select Harvest Class below the results and select from your list of Harvest Classes.

 

7. The Color Results show the range of colors present in the fruit. The x-axis is the hue value, and the y-axis is the number of pixels from the scan that fall within that range of hues. 15 hue values are grouped into each bar to provide a visual summary of the results.

 

8. You can change the grouping of the hue values by tapping on ‘Color Band’ just below the display.

 

9. When finished scanning, ensure the device is connected to Wi-Fi or a cellular network so the scans can upload. Results will show up your device when they have finished processing.

 

10. The Size Over Time chart displays the average size of the fruit in the block from related HQV events. The x-axis is the event date. The y-axis is the average size in mm.

The main blue line is the average size of the scans within the same block, within the same event, with each point being the HQV event date.

 

The shaded blue represents the size range of the fruit detected used to calculate the average.
