The invention provides a real-time modeling method and system for cooperative work of land and flight scanning devices, and relates to the technical field of scanning and modeling. The method comprises the following steps: preliminarily scanning a target area by using a land scanning device to generate three-dimensional point cloud data; a flight scanning device is used for conducting supplementary scanning on the complex area, and the coverage blind area of ground scanning is made up; fusing the land scanning data and the flight scanning data to generate a high-precision three-dimensional model; based on real-time data analysis, a flight path is dynamically adjusted to improve scanning efficiency and coverage rate. Through cooperative work of the land and the flight device, the modeling precision and efficiency are effectively improved, and the method is suitable for complex terrains and multi-scene application and has high real-time performance and reliability.

The invention discloses a management method for tracing a corresponding relation between an outer packaging box and an inner packaging product of a color box, and the method comprises the steps: building a production informatization management system and an anti-counterfeiting traceability system, and correspondingly generating a product information two-dimensional code according to different products in the color box through the production informatization management system; the anti-counterfeiting traceability system generates corresponding anti-counterfeiting codes one by one according to different products in the color box, the anti-counterfeiting codes and the product two-dimensional codes generated in the first step are printed on labels through printing equipment, and the corresponding anti-counterfeiting codes and the corresponding product two-dimensional codes are pasted on the color box through production equipment; compared with the prior art, the management method has the following advantages that data are imported into the production informatization management system in advance, so that during shipping, only the box number codes on the shipping marks of the outer packaging boxes need to be directly scanned through a scanning instrument, and corresponding data and corresponding 1D data are exported from the production informatization management system through the corresponding box number codes and sent to clients; and unboxing and scanning of bar codes on the color boxes and re-boxing are not needed.

The invention provides an instant depth acquisition method, a three-dimensional imaging method, equipment and a medium. The method comprises the following steps: acquiring a current-moment first point cloud frame of a to-be-acquired scene and a current-moment first image frame of the to-be-acquired scene; the first point cloud frame comprises first point cloud acquisition and a first depth map; the first image frame comprises a plurality of first target areas; the process of acquiring the point cloud acquisition at the next moment comprises the following steps: carrying out region adaptive scanning and global scanning on a scene to be acquired based on a plurality of first target regions of a first image frame, a first depth map and scanning angle resolutions set by different target regions; acquiring point cloud acquisition at the next moment; and acquiring a depth map at the next moment based on point cloud acquisition at the next moment. According to the method, on the basis of the point cloud and the image frame at the current moment, the point cloud collection and the depth map at the next moment can be obtained in real time, and real-time obtaining and processing of depth information are achieved.

The embodiment of the invention provides a reinsurance policy data processing method and device, electronic equipment and a storage medium, and relates to the technical field of data processing. The method comprises the following steps: acquiring an initial reinsurance data table; screening the initial reinsurance data table according to a first screening rule to obtain data of a plurality of first target insurance policies, the first screening rule comprising a first field in a plurality of fields and a field value of the first field; summarizing the data of the plurality of first target insurance policies to obtain target data; and newly adding a target field in the initial reinsurance data table, and adding the target data into the target field corresponding to the row where the data of the first target insurance policy in the initial reinsurance data table is located, thereby obtaining a target reinsurance data table. According to the embodiment of the invention, the target reinsurance data table can be obtained after the initial reinsurance data table is processed, so that cross-field data scanning is reduced, the time for screening the data of the reinsurance policy is shortened, and the screening efficiency of the data of the reinsurance policy is improved.

The invention belongs to the technical field of nuclear reaction, and discloses a nuclear reactor physical numerical simulation method and system based on a CPU / GPU heterogeneous platform, and the method comprises the steps: assuming that each resonance nuclide adopts a subgroup fixed source equation needing to be solved for N times on average; according to subgroup transport calculation, circulation is carried out on each subgroup of each resonance nuclide in a calculation system, for M resonance nuclides, the number of calling times of a characteristic line method transport solver by a subgroup fixed source equation is MN, and characteristic line scanning calculation needs to be carried out for each calling; the MN subgroups are combined together to form a'multi-group 'structure; the multi-group structure is applied to subgroup fixed source transport calculation, feature line scanning is carried out in the whole multi-group structure at the same time, and fixed source flux of all subgroups is solved at the same time; a multi-group grouping calculation method is adopted, it is assumed that the number of energy groups adopted by final multi-group transport calculation is G, and sub-group fixed source calculation of a multi-group structure is conducted through existing multi-group transport variables.

The application provides a method for sending a data packet based on a Wi-Fi switch circuit. The Wi-Fi switch circuit comprises a power module, a switch module and an output module. The power module comprises a button cell and a front-stage capacitor. The switch module comprises a key switch. The output module comprises a Wi-Fi chip. The method for sending a data packet comprises the following steps: in response to pressing the key switch, the Wi-Fi switch circuit is instantaneously turned on, the Wi-Fi chip is triggered to enter an initialization state, it is determined whether the Wi-Fi chip has been bound to a receiving end device, the Wi-Fi chip sends a data packet, and the front-stage capacitor supplies power to the Wi-Fi chip when the Wi-Fi chip sends the data packet. After the Wi-Fi chip sends the data packet each time, the Wi-Fi chip enters a sleep state. During the sleep state, the button cell charges the front-stage capacitor, so that the front-stage capacitor stores electric energy. After a predetermined time length arrives, the Wi-Fi chip enters a working state again.
