Optical Viscosity Measurement Using Falling Ball Image Analysis

The patent replaces complex mechanical viscosity measurement systems with an optical detection system. Instead of using mechanical rotors or cylinders that physically interact with the fluid, the invention uses a camera to capture images of a ball falling through the fluid, then processes these images computationally to determine viscosity. This substitution of mechanical measurement with optical detection and image processing simplifies the device structure while maintaining measurement capability.

The patent creates an optical copy (image) of the ball's position and motion in the fluid rather than directly measuring physical properties. By capturing visual information and analyzing the ball's trajectory, speed, and position changes over time, the system infers viscosity without direct mechanical contact. This copying approach allows for non-intrusive measurement and simplifies the physical device structure.

The system performs automatic image capture, processing, and viscosity calculation without requiring manual intervention. The camera automatically captures images of the ball's motion, the processing unit automatically analyzes the image data to determine velocity and position, and the system automatically computes viscosity based on the falling sphere method. This automation eliminates complex manual operations while maintaining measurement accuracy.

The patent replaces manual mechanical measurement operations with automated optical detection and computational analysis. Instead of requiring manual timing, distance measurement, or mechanical calibration, the system uses image processing algorithms to automatically extract motion parameters and calculate viscosity, significantly simplifying the operation process.

The patent uses inexpensive components to achieve viscosity measurement: a standard camera instead of expensive optical measurement systems, a simple ball instead of specialized measurement spheres, and computational algorithms instead of complex mechanical instruments. These inexpensive, readily available components dramatically reduce manufacturing costs while maintaining measurement capability through software-based analysis.

The patent replaces expensive mechanical viscosity measurement instruments with affordable optical and computational components. By using a camera, processing unit, and software algorithms to analyze ball motion in fluid, the system eliminates the need for costly mechanical viscometers, reducing both manufacturing cost and device complexity.
