The invention discloses a binocular vision-based water contact angle online detection method, which comprises the following steps of: spraying water on the surface of an object to be detected and standing until water drops on the surface of the object are in a steady state, acquiring an optical image of the water drops on the surface of the object based on a binocular stereoscopic vision technology, irradiating the water drops through laser assistance, and extracting a center line of a laser image, pixel coordinates of each laser stripe of the picture are obtained and converted to the same reference coordinate system, a point cloud picture is obtained, three-dimensional space coordinates of water drops are constructed, finally, the cross section of the water drops is taken, a water drop contour curve is fitted, and the water contact angle is calculated. The water contact angle of any surface can be obtained without sampling and precise optical conditions, so that the limitation of the prior ...
