Conventional checkerboard-based computer vision technique for water flow rate measurement faces challenges due to the reflection on water surface and turbulence of the waves. Embodiments herein provide a method and system for the water flow rate measurement using fusion of LOGKER-based computer vision and audio processing techniques. The method utilizes the LOGKER-based computer vision technique that accurately captures a water flow rate from a rotated faucet angle of a faucet handle and fuses the captured water flow rate with a microphone-based audio inputs, to obtain a final water flow rate. The method displays the final water flow rate contextually on a two-way mirror, using an Organic Light Emitting Diode (OLED) display, to a user. The method is less susceptible to external factors and computationally faster as it tracks black and white lines on the LOGKER instead of displacement of pixels.
