英文摘要：

The digital radiography(DR) location technique based on stereo vision,whose detection efficiency is higher than that of film,is brought forward.The key techniques of DR location are discussed.Depth location of defect based on rotation parallax is studied emphatically.It has more advantages than location based shift parallax.Than the source of error in depth locating is analyzed in detail and the solution is provided.The high location precision can be obtained using these techniques.
