Sorting and packaging of apples by means of digital image processing
In the process of packaging high quality apples the proper placement of the fruit in the tray is critical (i.e. the most appealing side should face towards the customer, all stalks should face into the same direction). Currently this sorting is done manually, at an additional cost of about 36 Euro (500 Schillings) per ton of apples. The automation of this process should result in a significant cost reduction. The first step of the packaging process rotates the apple so that its symmetry axis is vertical with either stalk or bloom facing upwards. This is done mechanically. The next step determines the position of the most appealing side of the apple (i.e. the horizontal angle) and decides whether stalk or bloom is facing upwards (the vertical angle). This is done by digital image processing. The apple is rotated by 360 degrees. A digital camera captures a sequence of images at different orientations and the image processing software measures fruit quality and vertical orientation in real-time. In the last step, a robot brings the apple to its ideal position and puts it into the tray.
