Rural distributed sewage lacks regular visual features,resulting in large artificial positioning error and strong hu-man factors.The research on intelligent visual positioning method for rural distributed sewage treatment is developed.The method by camera equipment acquisition machine visual images of distributed sewage treatment outlet,the color image into gray image,us-ing Canny algorithm to detect the image edge,and through the scale invariant feature transformation extraction sewage treatment vi-sual image features,calculation feature similarity,matching characteristics,combined with the machine vision algorithm,calculate sewage outlet precise coordinates,distributed sewage positioning.The experimental results show that the proposed method can ac-curately detect the image edge,and the average positioning error of 6 different types of rural distributed sewage discharge outlets is not more than 2 cm,and the error between the positioning results and the actual position is small,realizing the accurate positioning of the sewage discharge outlet.
