The invention discloses an intelligent character recognition and structured processing method based on multi-modal deep learning, and belongs to the technical field of character recognition, and the method comprises the following steps: 1, receiving an image uploaded by a user, carrying out the detection of a character main body region, and extracting a main body region image containing characters; step 2, preprocessing the image; 3, performing character target detection on the preprocessed image by adopting a YOLOv8 model, and positioning a text region; step 4, identifying the detected character area by using a CRNN model, and outputting text content; 5, performing layout analysis on the recognition result, and determining a reading sequence and a logic structure of the text; and step 6, using a natural language model, combining the text content and the coordinate information, and carrying out structured output on an identification result. Multiple tasks such as business licenses and licenses are integrated into one model, the problem of multiple models in the prior art is solved, the resource utilization rate is high, and the recognition precision is high.

The invention discloses a multi-terminal video monitoring processing system based on intelligent character recognition, which relates to the technical field of video monitoring, and comprises a monitoring equipment terminal, a monitoring transmission terminal, a server terminal and a client. Under the support of a control system, massive video data monitored by front-end character recognition cameras in different areas are encrypted layer by layer, stored and transmitted to a client in real time, Web clients and mobile clients of different levels are decrypted to different degrees through a security decryption device, and the video data are transmitted to the client in real time. Intelligent dynamic remote intelligent video monitoring and video playback of different levels and different regions are realized, the problem of cross-region multi-level and multi-level management of each industry is solved, and for units requiring mutual confidentiality of internal functional mechanisms, monitoring among the levels is encrypted, and lower levels cannot check and monitor in an override manner, so that the security is high.

The invention discloses an intelligent character recognition method based on scanned character edge color deviation, which comprises the following steps of: 1, preparing a data set: collecting a single character picture only containing a handwritten or printed body, cutting a complete text line into single character areas, and labeling category labels; 2, multi-dimensional feature extraction: for each input picture, extracting texture and morphological features and point cloud color features; 3, model training: splicing the texture and morphological features and the point cloud color features to form a high-dimensional feature vector, and training a random forest model by using the high-dimensional feature vector; and 4, model application: inputting a to-be-processed scanning picture into the trained random forest model, and outputting a division result of handwritten and printed character areas by the random forest model to finish segmentation of handwritten and printed characters.
