The computer vision imaging technology is adopted to peek gun tube’s bore

such as crackle flaw

ablation stain

local fling rib rupture and so on.Micro-displacement sensor and microcomputer measurement and control technology are applied to sample the inner diameter data.The data transmission is realized by the upper and lower computer communication mechanism

data processing is carried out by the upper computer and data acquision is carried out by the lower computer.The gun tube’s bore and inner diameter can be peeked and measured with higher precision

and the gun tube’s life prediction also can be gained.The system has been successfully applied in ground artillery maintenance center of a department

and the actual measuring result indicates that the gun tube’s bore can be peeked clearly and the life prediction is accurate

so the system can meet the need of bore peek and diameter measurement.
