This Android app allows to collect images by taking pictures with a smartphone camera and to upload them directly as part of a dataset on Roboflow, using Roboflow’s Upload API.
The app is being developed with MIT App Inventor by Lars von Wangenheim, Christiane Gresse von Wangenheim and Jean C. R. Hauck from the initiative Computação na Escola of the Department of Informatics and Statistics at the Federal University of Santa Catarina.
The app uses the extensions: TaifunImage and ImageBase64
Based on the generic app code you can easily adapt the app in order to collect images for your data set:
- Import the .aia code into App Inventor (.aia)
- Include your Roboflow private key and data set name in the code
- Build the APK and share it in order to start image collection
As part of our research project in which we aim to detect rip currents we are using the app for crowdsourcing the image collection of beaches of the Santa Catarina Island in Brazil. We intend to use this app in the course we are developing for teaching object detection in public middle and high schools in Brazil as part of our initiative Computação na Escola of the Department of Informatics and Statistics at the Federal University of Santa Catarina.
