Method and device for estimating height of 3D printing object formed during 3D printing process and 3D printing system

A method and a device for estimating the height of a 3D printed object formed during a 3D printing process are disclosed. The method comprises the following steps: extracting more than one temperature related data of a 3D printing object formed in a 3D printing process, and establishing an artificial neural network model for estimating the height of the 3D printing object by utilizing the extracted temperature related data; and estimating the height of the 3D printed object by inputting the newly measured thermal image and the one or more temperature related data values into the artificial neural network model. And the height of a 3D printing object can be measured in real time. 公开了一种用于估算3D打印过程中形成的3D打印物体的高度的方法和装置。该方法包括提取在3D打印过程中形成的3D打印物体的一个以上的温度相关数据，通过利用提取的温度相关数据建立用于估算3D打印物体的高度的人工神经网络模型；以及通过将新测量的热图像和一个以上的温度相关数据值输入到人工神经网络模型中估算3D打印物体的高度。可以实时测量3D打印物体的高度。
