The invention provides a method for positioning by using laser three-dimensional projection in hull construction. A projector fixing portal frame is arranged on the ground. A ship body segmented structure is arranged below the portal frame, a laser projector is fixed to the upper portion of the fixed portal frame, the outline of a T-shaped profile projected by the projector of the laser projectorirradiates the faces of the segmented structures on the two sides, the segmented structures are arranged on a segmented structure jig frame, and a projector software system is fixed to the bottom faceof one side of the fixed portal frame through a support. T-shaped material structure positioning point and line projection is carried out through the steps of ship body structure model processing, projection coordinate system conversion, establishment of a ship body T-shaped material structure projection positioning file, format importing into a laser projector software system, establishment of aprojected ship body structure real coordinate system, establishment of an operation package and projection operation. The positioning precision of the hull structure can be detected through laser projection images. The method is suitable for being applied to laser three-dimensional projection positioning in hull construction.

本发明提出的是一种船体建造中使用激光三维投影定位的方法。在地面上设置投影仪固定门架，在门架下面为船体分段结构，在固定门架上部固定有激光投影仪，激光投影仪的投影仪投影的T型材轮廓照射在两侧分段结构的面上，分段结构设置在分段结构胎架上，在固定门架一侧的底面上通过支架固定有投影仪软件系统。经过船体结构模型处理、投影坐标系转换、建立船体T型材结构投影定位文件、格式导入激光投影仪软件系统、建立被投影船体结构现实坐标系、建立作业包和投影作业的步骤进行T型材结构定位点、线投影。本发明能够激光投影影像检测船体结构定位精度。适宜作为船体建造中使用激光三维投影定位的方法应用。
