Use Visual Recognition on drone pictures

Alert - Watson Visual Recognition service has been discontinued

The steps in this section are no longer available.

The Tello has a low level protocol that allows you to take pictures. This flow sends the take picture command and receives / reconstructs the picture data from the Tello. Then it calls the Watson Visual Recognition service to classify what is in the image.

Task

Connect to the IBM Cloud

Use an ethernet cable to hardwire your laptop to your network so that it can reach the Internet. Connect over WiFi to the Tello drone.

Create a Watson Visual Recognition service instance

  • Return to your Node-RED browser window
  • Recall that in Setup / Part 2 you installed the node-red-node-watson nodes which provide a collection of Node-RED nodes for IBM Watson services
  • Import the solution flow
  • Double-click on the visual recognition node
  • Paste the API key from the clipboard into the Visual Recognition node
  • Click on the Done button
  • See screenshot:
