7 results about "Historical maps" patented technology

The application discloses a robot map updating method, which comprises the following steps: step 1, a robot establishes a current map in a current environment; step 2, the current map is updated according to the angle relationship between the current map and a map stored in a historical map library last time, the updated current map is stored in the historical map library, and the updated current map is updated as the map stored in the historical map library last time, so that the current map established in step 1 is updated; wherein each frame of map stored in the same historical map library represents the current environment.

The present application belongs to the technical field of space planning, and discloses a land space planning suitability evaluation system based on space-time big data; by constructing a projection zone distribution topology graph and an anisotropic distortion tensor field, coordinate distortion at the junction of projection zones is accurately identified and corrected. By using a spatial autocorrelation analysis method, systematic deviation areas in the residual system in the process of digitizing historical maps are identified, and a residual propagation influence domain model is established, so that accurate coordinate correction of each position point is realized. Through an adaptive fusion mechanism of compensation components, the fusion accuracy of multi-source space-time data is improved. A coordinate correction confidence evaluation mechanism is introduced, data uncertainty information is included in the suitability evaluation process, and more scientific and reliable evaluation results and confidence intervals are provided for decision makers.

The method, the display method, the electronic device and the storage medium are used for updating the current map with the historical map as the initial map after the single-point laser radar detects the environmental parameter each time in the process of executing the cleaning task by the self-moving cleaning device, determining whether the current map has the superposition according to the angle difference between the main direction of the current map and the main direction of the historical map in the process of executing the cleaning task, and achieving the accurate detection of the superposition without increasing the hardware cost of the self-moving cleaning device with the single-point laser radar, accurately and completely executing the cleaning task, and successfully returning to the base station after executing the cleaning task or after the cleaning task is completed, and improving the user experience.

This disclosure presents a map processing method integrating image semantics and a head-mounted display device. One specific implementation of the method includes: in response to detecting semantic change detection information of the head-mounted display device, generating semantic record information containing semantic landmark information based on acquired surrounding environmental data; generating current map information based on the semantic record information; and in response to detecting that the head-mounted display device meets preset change conditions, generating updated map information based on the current map information and target historical map information, or based on surrounding environmental data, device motion data, and the current map information. This implementation can shorten the time spent on map construction and maintenance, improve the accuracy of map construction and maintenance, shorten the time spent on relocation and improve the accuracy of relocation, and enhance the user's spatial interaction experience.

The proposed invention is a dynamic platform designed to revolutionize the visualization and recording of human history. It is an HTML / JAVA-based system accessible through any browser, facilitating simultaneous edits on a map to document historical events and the evolution of civilization across Earth's history. Crowd input forms the backbone of this platform, with the goal of digitizing human history onto a single map for each time period, potentially creating one unique map for each month in human history. This ambitious endeavor aims to comprehensively digitize all global historical events and cultural establishments. Users can seamlessly “flip” between different time periods, allowing for the visualization of the evolution of key cultural establishments over time. Additionally, the platform enables users to compare events and cultural establishments that share the same time period on the same map, providing valuable insights into the interconnectedness of historical events and their impact on global civilization.

This invention discloses a method for managing robot maps. The method includes: Step 1, the robot builds a current map within the current environment; Step 2, based on the angular relationship between the current map and the previously stored map in the historical map database, the current map is stored in the historical map database. By saving historical map records based on the same environmental area, a map that more closely matches the actual scenario is preserved, increasing the stability and richness of the map. This also maintains the validity of the robot's historical maps and effectively improves the robustness of the mobile robot's mapping and localization algorithms.
