Assignment: Investigating which QR code sizes and material are most suitable for drone data collection

Investigating which QR code sizes and materials are most suitable for drone data collection

Problem statement

The current shortage of labour is causing an increasing interest into innovations in for example greenhouses. Growers grow vegetables and flowers in different growth stages, from seedling to sellable plant or vegetable. Currently, we are working together with our drone partner to develop an automated pipeline for assessing seedling sizes in a tray. This information is important for a grower to have increased insight into his sellable product and the differences of growth stages within the greenhouse. Currently, we are distinguishing between trays and batches by using QR codes, which are automatically detected and decoded by our software. However, some of these QR codes are not decodable due to several reasons, such as shadow, marker material and light conditions. Hence, we would like to identify which QR code size and material is most suitable for drone data collection under different environmental circumstances.


The task for this project is to investigate which QR code material and under which camera settings the QR codes are best decodable by our marker detection. Therefore, you could start with a literature review of currently available research into this topic. Subsequently, you can test your insights and perform your experiments by using a drone and collecting data on several fly heights and by using several camera settings. In the end, you will give a clear overview of your results, which will be used for our QR code requirements in the future!
