By analyzing the high-speed railway overhead contact system testing demand and the insufficiency in cur-rent testing methods,according to the testing environment and requirements,the paper puts forward a design pro-posal for portable measuring instrument based on the binocular vision imaging principle. It introduces the composi-tion structure,measuring principle,measuring process and testing of the instrument. Lab studies show that,theinstrument can meet the precision requirement of railway contact wire measurement,capable of field measurement,thus can improve the contact wire testing efficiency.
