Abstract

The invention discloses an intelligent human-computer interaction method and device based on graphic-text matching, belonging to the field of computer vision. The method includes: collecting user's voice information and converting it into a text sequence, using natural language processing technology to extract target features in the text sequence; collecting real environment images, and using a deep convolutional neural network to extract natural image features from the original image data ; Calculate the matching degree of each target in the original image and the target in the text sequence, take the target in the image with the highest matching degree as the matching result, and convert it into a machine instruction. The invention combines computer vision technology and natural language processing technology to realize the matching of complex commands and real images, and can automatically locate the relevant entity targets in the image according to a natural language expression command, making the interaction process more natural, and can be applied to disabled robots, rescue A wide range of scenarios such as robots and special robots.
