Application of parallel binocular vision system in area measurement using USB-based camera

An area measurement system with common USB camera is developed based on the measurement principle of parallel binocular vision system.First,the binocular vision system is calibrated.Second,the image's radial distortion is corrected.Finally,the edge detection and area measurement of the object to be measured are performed using wavelet transformation and morphology. This system is easy to install and has low cost and good real-time performance,providing a method for area measurement.
