Some methods metering instrumentation ship's hull deformation are generalized
and their advantages and disadvantages are compared. A new raster metering method is put forward
which not only has some advantages of small bulk
light weight and ease of installation
but also has higher precision. A high precision sub-pixel location technology is used in this approach and the precision of angle metering can be higher. Through theoretic analysis and practical experiment
the results show the precision of angle metering has excelled 5 arc second.
