概要
Smart cup detection is an innovative solution that uses a compact normalized histogram to accurately detect the presence and position of cups. This solution includes advanced algorithms that offer six unique features to enhance system efficiency and the user experience. This solution reliably detects the presence and position of a cup, irrespective of the size and material of the cup. It also monitors liquid level and steam mitigation, and ensures user safety by stopping to fill when a hand is detected.
This solution is customizable to suit diverse applications and products. It is ideal for professional beverage dispensers such as soda and hot/cold-water dispensers in restaurants, offices, and schools, as well as home appliances like refrigerators, coffee machines, and water dispensers.
Based on ST's fourth generation of FlightSense sensors, the STSW-IMG051 software package works with 8x8 multizone Time-of-Flight (ToF) sensors: the VL53L7CH or the VL53L8CH, using the same unique software. The performance is not affected by target reflectance, making it suitable for use in low light conditions. The sensors are small and can be easily integrated and hidden behind a dark cover glass.
To run the GUI, a Nucleo expansion board (X‑NUCLEO-53L7A1, X-NUCLEO-53L8A1) is required, with a NUCLEO-F401RE Nucleo board. In addition, you can use the breakout boards (SATEL-VL53L7CH or SATEL-VL53L8) connected to the STM32 Nucleo board.
