This demonstration fully exploits AnaLogic/Eutecus's Bi-i vision system with the ACE16k chip in small object classification at ultra-high frame rates.

Objects (pills and capsules) of varying sizes and shapes are placed along the perimeter of a rotating disc. The Bi-i is positioned with its sensor-processor array focusing to a point in the path of the pills (with only one pill in its view) while the disc is rotated at a speed of over 17 m/s. The task is to classify each object based on size and shape, and to detect whether the deviation from the expected shape is larger than a certain threshold (which indicates that a piece of the pill/capsule is missing). With the help of the ACE16k sensor-processor chip, the Bi-i samples the image of the disc at a rate of over 30,000 frames per second. The algorithm for classification and detection is executed every time a pill gets in the view of the sensor. Overall, the system is capable of processing over 3,000 objects in a minute.

The complete application developed with the Bi-i Software Developer Kit and the InstantVision libraries runs on the standalone Bi-i platform. The program can be easily adapted to the classification and quality inspection of other kinds of "small objects" (e.g. foreign particles in liquid, small grains or metal parts, etc.).
