In order to realize the non-contact detection of colorless liquid level in transparent bottle, a kind of liquid level real-time detection system was designed. The system acquires the real-time image of products through a industrial digital camera, and then retrieve the liquid region after a series of pretreatments which are based on OpenCV open-source platform, a bounding box algorithm suitable for liquid level detection was proposed, the height of liquid level can be obtained. The white background and a special design of light source highlight the liquid area, the system can realize real-time detection without external measuring instrument. In a test including 100 images of products with different liquid levels, the measured results showed that this system can get the height of bottled liquid rapidly and accurately, the maximum relative error is 0.8%, which has a good accuracy and real-time performance.
