The method comprises the following steps: collecting a plurality of laser directional energy deposition area images, manually marking a molten pool label of each image, and further constructing a training set; building a full convolutional neural network, inputting the images in the training set into the neural network, predicting the existence value of the molten pool, further combining with the marked construction loss function, optimizing to Nash equilibrium, and obtaining an optimized neural network; collecting a to-be-detected image, inputting the to-be-detected image into the optimized neural network, and judging whether the image has a molten pool area; if the molten pool exists, graying the image to obtain a grey-scale image, and then carrying out binarization to obtain a binary image; and performing a topological structure analysis method on the binary image to obtain a molten pool contour pixel coordinate set of the image, and further calculating the area of the molten pool. According to the invention, the molten pool in the laser directional energy deposition process can be recognized, the area of the molten pool is calculated, and the manufacturing process can be regulated and controlled easily.
