Caliper is widely used in internal pipeline inspection work and the research of distance measuring for the caliper is very significant.Through studying the domestic and foreign related literature,the commonly used pipeline distance measuring technology is summarized and the ad-vantages and disadvantages of different distance measuring technology is analyses in this paper. Based on the structure and inspection principle,a new type of weld positioning method and sliding coefficient of odometer wheel are proposed and have a guiding significance for short distance measuring.A new algorithm is proposed to deal with the mileage error caused by the rotation of caliper and effectively improve precision of the short distance measuring.As to the fact that a same pipeline include many different length pipe,a algorithm that can confirm pipeline length is proposed and further improve precision of long distance measuring.
