The task of relevance score assignment to a set of items onto which an artificial neural network is applied is obtained by redistributing an initial relevance score derived from the network output, onto the set of items by reversely propagating the initial relevance score through the artificial neural network so as to obtain a relevance score for each item. In particular, this reverse propagationis applicable to a broader set of artificial neural networks and / or at lower computational efforts by performing same in a manner so that for each neuron, preliminarily redistributed relevance scoresof a set of downstream neighbor neurons of the respective neuron are distributed on a set of upstream neighbor neurons of the respective neuron according to a distribution function.

A virtual window assembly for an airborne vehicle includes at least one camera configured to capture a panoramic and time-resolved image data stream from the view to the outside of the airborne vehicle, at least one image data processor coupled to the camera and configured to receive the captured image data stream and split the image data stream into a plurality of partial image data streams corresponding to different viewing angles of the panoramic image data stream, and a plurality of electronic displays mounted to an inside of a hull of the airborne vehicle, coupled to the image data processor and configured to receive the partial image data streams. Each of the electronic displays is configured to display one of the partial image data streams so that the physical mounting location of the electronic displays in the airborne vehicle corresponds to the associated camera viewing angle of the displayed partial image data stream.

The invention provides a unified calibration model for robot structure parameters and hand-eye relations. A three-dimensional sensor is used for replacing optical tracking equipment which needs to beused in robot parameter calibration; a robot-three-dimensional sensor system is taken as a new robot system; a three-dimensional sensor coordinate system is regarded as a new robot tail end coordinatesystem; and the hand-eye relations in the original robot-three-dimensional sensor system are simultaneously calibrated in the process of calibrating D-H parameters of a new robot, namely, the calibration work of the robot structure parameters and the hand-eye relations are completed through one-time calibration according to an existing method, and the calibration precision is improved. The coordinate system conversion relation of a traditional method is as follows: a laser tracker coordinate system l - a robot base coordinate system w - a robot tail end coordinate system n - a three-dimensional sensor coordinate system s; and the coordinate system conversion relation of the unified calibration model is as follows: a target coordinate system m - a robot base coordinate system w - a three-dimensional sensor coordinate system s. By means of the unified calibration model, the calibration work is simplified, the calculation work is reduced, and the calibration precision is improved.

The invention discloses a triangle intersection detection method applied to three-dimensional visual simulation of remote operation, and proposes a new triangle intersection detection algorithm for fine collision detection of three-dimensional graphic models. Compared with the traditional triangle intersection test algorithm, the present invention does not have the step of exchanging two triangles for recalculation, thereby saving a lot of calculation work by reusing the calculation results of the same triangle, and improving the speed of fine collision detection of 3D graphic models as a whole.

The invention provides an expressway charging method based on bidirectional verification of social evaluation-credit data. The method has two party verification mechanisms including a client side and a charging station side. A customer submits the registration information to complete registration through the mobile communication terminal, after registration, the registered customer can access a central platform database of an expressway management center to acquire arrearage information saved in the central platform database, according to the arrearage information, the arrearage is paid up. A service management server of the expressway management center conducts to verify the registration information, calculate the arrearage and issue the corresponding charging instructions uniformly, the charging station side charges previous arrearages and current tolls for the registered customers and unregistered customers according to the instructions issued by the service management server. The expressway charging method can save the expressway chargeable time and improve the traffic quality of the expressway, at the same time, the charging method can simultaneously charge the previous arrearages and current tolls of vehicles, and provide more channels for the payment of the customers to facilitate the expense management of the expressway management center.
