Plate bending by line heating is a main forming method for bi-curve shell plate in shipbuilding. It is usually operated by means of template,so it is hard to automatic process. Researches on the relations between line heating parameters and forming have been published at home and aboard. It is necessary to measure angle deformation of plate after line heating. A new high precision measuring device for angle deformation of bending plate by line heating is presented and developed in this paper. It comprises two high precision encoders that form measuring mechanism for angle. It is easily used. And very little angle deformation of bending plate can be measured with high accuracy ±0.01°.
