The invention provides a remote unmanned aerial vehicle cluster control method and system based on 3G (the 3rd Generation Telecommunication) and GPRS (General Packet Radio Service) cell phone communication and belongs to the technical field of unmanned aerial vehicles. Each unmanned aerial vehicle is provided with an independent unique electronic identification code by integrating a cell phone communication module into a flight control computer board card; as long as the system is started and electrified, the current relevant information of the unmanned aerial vehicle is transmitted to a remote control center; a permission instruction is necessarily applied from a control center for each flight; information such as an airway plan is made uniformly in the control center; and the information is transmitted to an operation terminal of the unmanned aerial vehicle through a cell phone communication module. Consequently the unmanned aerial vehicle cannot fly away without a headquarter control instruction. The state of each unmanned aerial vehicle is fed back to the control center and can be shared with networked data of relevant national supervision departments so as to play roles in unified supervision and scheduling. In addition, the on-site operation personnel do not need professional knowledge such as airway point setup; and the unmanned aerial vehicle can be operated by common people subjected to simple training, so that the problem of staff shortage in unmanned aerial vehicle control is solved.

Image super-resolution method based on SAE and sparse representation

The invention discloses an image super-resolution method based on SAE and sparse representation, and belongs to the field of image processing. The image super-resolution method mainly comprises an off-line training stage and a test refactoring stage, wherein in the off-line training stage, image characteristics extracted by an SAE (Sparse Auto Encoding) model are subjected to dictionary training, and a dictionary pair reflecting corresponding relations of high-resolution images and low-resolution images is established; in the test refactoring stage, low-resolution images inputted by a user are subjected to super-resolution reconstruction by the obtained dictionaries and a sparse representation method. Through the application of the image super-resolution method, unsupervised learning training is performed on original image sampling data by using the SAE model, so that the defects that manually designed operator characteristic extraction is time-consuming and strenuous and the extracted characteristics are single are avoided, meanwhile, image characteristics represented by SAE compression are directly used for training of the high-low-resolution dictionary pair, the dictionary training is facilitated, lost detail components in the images can be estimated by the sparse representation method, and higher-quality high-resolution images can be restored from the low-resolution images conveniently.
