An unmanned aerial vehicle vision navigation landing system based on a multi-scale marker comprises the multi-scale marker, an identification and attitude resolution algorithm and a navigation system. The multi-scale marker uses an image center as a world coordinate system origin (0,0,0). The side length of the origin is one pixel. The origin extends in four directions around the pixel. In every outward extension, the side length of a black matrix becomes two times of the original side length. The multi-scale marker is automatically generated according to the pixel dimension and the integral dimension of the marker. Supposing the world coordinate system is at the central point of the marker, the z-axis coordinate of the point on the marker is zero and the central coordinate of each matrix is known; a rotational translation matrix of a camera relative to the marker is calculated. The navigation system comprises a coordinate system calibration module, an image acquisition module and an operational processing module. The operational processing module is used for target identification, attitude resolution, navigation control and communication with an unmanned aerial vehicle flight controller. The unmanned aerial vehicle vision navigation landing system has advantages of high dimension change adaptability, high attitude resolution capability and relatively high expandability.

A system of radio frequency communication between Readers and Tags, the system comprising at least one tag Reader and a plurality of Tags, each tag is given a unique tag ID, deployed in a region in which at least some of the Tags are in radio communication with the tag Reader and a Media Access Control protocol such that the tag Reader is configured to send and receive radio communication to and from at least some of the plurality of Tags. The plurality of Tags are configured to send and receive radio communication to and from the tag Reader and the Media Access Control protocol is configured to control the radio communication between the tag Reader and the plurality of Tags The Media Access Control protocol includes a multi-dimensional addressing scheme allowing Readers to efficiently address tag communities ranging from small to very large in unicast, multicast and broadcast modes. The multi-dimensional addressing scheme enables division of the plurality of Tags into a number of groups for different stages of Media Access Control protocol processing, based on different portions of the tag ID. A hash function is used to transform the tag ID into a pseudo random ID, so as to achieve better spreading of tag population and lower statistical dependency between dimensions. The MAC has an inherent flexibility in the sense that it allows readers to communicate with different versions of tags and also to optimize communication parameters to reader's capabilities, without pre-configuration of the tags. Furthermore, the MAC supports means to achieve very high access reliability, such as relay between tags, and the ability to work with tags that alternate between active and sleep mode) including means for power savings. All of these novel features, coupled with some prior art concepts like collision resolution algorithms, result in a scalable MAC protocol for an active RFID system employing multiple access.

The present provides for consistent resolution of data conflicts when synchronizing data between two or more devices in order to reduce the likelihood of an infinite synchronization loop within a distributed computing system. More particularly, example embodiments provide for a conflict resolution algorithm capable of generating unique values for properties that are in conflict. Data selection criteria can then be used to determine which of the properties should be used to resolve the conflict. Such data selection criterion increases the likelihood of providing consistent resolution of similar data conflicts between other devices in the distributed system.

The invention provides a deep attention coding and decoding single-image super-resolution algorithm based on perception loss guidance. The deep attention coding and decoding single-image super-resolution algorithm comprises the following steps: constructing a deep attention coding and decoding network model based on perception loss guidance; designing a perception loss objective function accordingto the network model; presetting network model hyper-parameters, and training a network model by adopting a back propagation algorithm according to the perception loss objective function; if the network model converges, outputting an expected high-resolution image, otherwise, returning to execute the previous step until the network model converges. According to the invention, the residual space attention unit is added into the network and is used for capturing and reconstructing more low-frequency information; the perceptual loss composed of an average absolute error and structural similarityloss is used as a loss function to optimize network parameters, so that the network can pay more attention to the visual sensitive area to store the visual information structure, the quality of the reconstructed image is improved, the reconstructed image has an excellent visual effect, and the reconstruction efficiency of the network is extremely high.
