Online monitoring system and method for laser deposition additive manufacturing

The invention provides a laser deposition additive manufacturing online monitoring system and method. The laser deposition additive manufacturing online monitoring system comprises a laser deposition additive manufacturing module, a robot system module and a computer module. In the laser deposition module, firstly, metal materials are deposited through laser in combination with a digital model path, meanwhile, data in the additive manufacturing process are collected in real time through the robot system module, and all the data are transmitted to the computer module. The acquired data is combined with the algorithm model module, the deposition layer surface and the molten pool state can be monitored in real time, monitored information such as defects or the molten pool abnormal state is fed back to the laser deposition module, real-time control is achieved, the workpiece surface forming quality is guaranteed, and the product percent of pass is increased. 本申请提供一种激光沉积增材制造在线监测系统及方法，包括：激光沉积增材制造模块、机器人系统模块和计算机模块；在激
