Automatic recognition of sample media content is provided, A spectrogram is generated for successive time slices of audio signal. One or more sample hash vectors are generated for a time slice by calculating ratios of magnitudes of respective frequency bins from a column for the time slice. In a primary evaluation stage an exact match of bits of the sample hash vector is performed to entries in a look-up table to identify a group of one or more reference hash vectors. In a secondary evaluation stage a degree of similarity between the sample hash vector and each of the group of reference hash vectors is performed to identify any reference hash vectors that are candidates for matching the sample media content, each reference hash vector representing a time slice of reference media content.

The invention discloses a novel construction setting-out method under an invisible condition of known points. A virtual resection method is adopted, and an instrument does not need to be erected at a resection point to observe the known points. The novel construction setting-out method is characterized by comprising the steps: setting two temporary working base points between the resection point and the two known points, wherein an extension line intersection point of the two known points and the two temporary working base points is a virtual resection point; solving coordinate values of the two temporary working base points according to a geometrical relationship among all the points, and further calibrating a position of a to-be-set-out point on a construction site. According to the method, the setting-out operation can be completed by utilizing a common total station, the process is simple, and a new choice is provided for the construction setting out of a building dense area.

The invention discloses a target layout device and method for photogrammetry on the top of a historic building. The device comprises an overhanging pipe, an exhausting pipe in the overhanging pipe is communicated with a sucking pump through an exhaust hole, a sucking disc communicated with the exhausting pipe is installed at the front end of the overhanging pipe, and a target for photogrammetry is adsorbed on the sucking disc; a touch type switch is installed at outer side of the front end of the overhanging pipe simultaneously, and a telescopic trigger rod in the touch type switch is parallel to the overhanging pipe and extends to the outer side of the sucking disc. The target layout method comprises the following steps: firstly, installing the overhanging pipe on an unmanned aerial vehicle through an installing frame, and communicating the exhaust hole at the root of the exhausting pipe with the sucking pump on the unmanned aerial vehicle; adhering the frontage of the target to the sucking disc, switching on a power source of the sucking pump so as to fix the target on the sucking disc, and uncovering a sticker on a sponge double-faced adhesive tape on the back of the target to expose a viscous surface; and enabling the unmanned aerial vehicle to take off to gradually approach to a correct position on the historic building and adhering the target to the building, and repeating the process until the layout of multiple and various targets is finished.

The invention discloses a plant pollen treating device which comprises a pollen collecting component, a pollen sorting component and a control circuit component. The pollen collecting portion is used for sucking pollen by the aid of negative pressures generated by a negative-pressure device and blowing the pollen into the pollen sorting component; the pollen sorting component is used for differentiating the quality of the pollen by the aid of electrostatic fields by the aid of up-down superposition electric fields; the control circuit component is used for supplying power for the negative-pressure device and the up-down superposition electric fields. The plant pollen treating device has the advantages that the pollen sucked by the aid of the negative pressures generated by the negative-pressure device can be blown into the pollen sorting component by the pollen collecting component, and accordingly the pollen of plants can be conveniently collected by users; pollen particles are tiny, are provided with negative charge and can be settled at different locations under the comprehensive conditions of gravity, electric field force, buoyancy and air resistance in the electrostatic fields generated by the pollen sorting component, accordingly, the purpose of differentiating the quality of the pollen can be achieved, and the quality of fruits of the pollinated plants can be improved.

The invention discloses a method for acquiring knowledge graphs based on deep learning, including acquiring heterogeneous data, dividing the heterogeneous data into structured data, semi-structured data and unstructured data; The heterogeneous data is processed accordingly to obtain a word vector; the word vector is input into the graph neural network model to obtain the first knowledge graph; the first knowledge graph is processed according to the clustering method and the bag-of-words model to obtain The second knowledge map, compared with the traditional self-supervision mode, the present invention is more flexible, different data sources can use different methods, and can also be selected according to different demand biases and scene characteristics, maximizing the advantages of each method , better reduce costs and improve the accuracy of results.
