Abstract

A liquid level detection system of detecting a target container includes a main body, an optical sensor, a fan and an operational processor. The main body has a supporting platform whereon the target container is disposed. The optical sensor is disposed above the supporting platform and adapted to output a detection image containing the target container. The fan is disposed on the main body and faces the supporting platform. The operational processor is electrically connected to the optical sensor, and adapted to analyze the detection image generated within an operation period of the fan and further to acquire an effective feature of the target container inside the detection image.
