209 results about "Geocoding" patented technology

Geocoding is the computational process of transforming a physical address description to a location on the Earth's surface (spatial representation in numerical coordinates). Reverse geocoding, on the other hand, converts geographic coordinates to a description of a location, usually the name of a place or an addressable location. Geocoding relies on a computer representation of address points, the street / road network, together with postal and administrative boundaries.

Crime scene reduction method based on video map and augmented reality

The invention relates to the city safety management field and concretely discloses a crime scene reduction method based on video map and augmented reality, and the method comprises the steps as follows: based on the space position information, building the coordinate city video monitoring network to obtain the video including the position information, correlating the video monitoring device with the data server; when the video target appears, obtaining the geography coordinate value of the video target in different frames of the city video monitoring network for forming the movement track of the video target; projecting the video and the video target on the electric map for forming the three-dimensional city video map; according to the real scenes of the video and video target on the city video map, building the virtual object, fusing the virtual object with the real scenes of city video map; displaying the augmented reality information to the user, having interaction with the user and changing the enhanced information. The video map is fused with the augmented reality technology, so that the crime scene can be displayed intuitively and realistically for offering effective basis for investigation.

ActiveCN111998766ASpatio-temporal decoherenceSolve the serious problem of atmospheric delayElectrical/magnetic solid deformation measurementSatellite radio beaconingHigh spatial resolutionObservation data
The invention relates to a surface deformation inversion method based on a time sequence InSAR technology. The surface deformation inversion method comprises the following steps of geocoding and imageregistration, differential interference pair generation, PS point selection, space-time unwrapping and error separation. Specifically, on the basis of an image registration mode, coarse registrationand fine registration are adopted, and the registration precision requirement in a TOPS imaging mode is guaranteed; for an atmospheric delay error, the layered atmosphere and the floating atmosphere are respectively processed by using different algorithms, so that influence of the atmospheric error is weakened to the greatest extent, and the deformation inversion precision is improved; and if GNSSdata is provided, atmospheric delay can be corrected by utilizing the observation data, and meanwhile, joint adjustment is carried out by taking the observation data as a constraint condition in an InSAR observation equation, so that the precision and reliability of a deformation result are ensured, and all-weather, large-area, continuous and high-spatial-resolution surface deformation monitoringis realized.

Geographical-position related hash virtual geocoding method and system

The invention relates to a geographical-position related hash virtual geocoding method and a system. The geographical-position related hash virtual geocoding method comprises the following steps of: diving the earth surface space repeatedly by adopting a region quadtree method based on the uniform division of a spherical surface; establishing indexes based on the hash plaintext coding for a terrain block and a scene block; indexing the user incarnation by adopting the hash plaintext virtual geocoding in the virtual world; and storing the indexes based on the hash plaintext coding of all data into a data index database based on the hash plaintext coding according to the division layer. According to the method, a set of space dividing and indexing mechanism is established and abstracted into a mathematical model, the space dividing and indexing mechanism can be expanded to be used for the real world division and the three-dimensional earth division, and the space dividing and indexing mechanism can be used as a core index data structure in a system to map various objects in the virtual world. Due to the hash plaintext virtual geocoding, the user incarnation and various element models in the three-dimensional earth scene can be indexed, and the relative positions of objects in the virtual world and the real world can be unified.

Star-loaded SAR image geocoding method based on star ground coordinate transformation

The invention provides a geocoding method for spaceborne SAR images based on conversion of satellite topocentric coordinates. A relation of six coordinate systems among the satellite topocentric coordinates is used, and an observation visual angle (an intermediate variable) is skillfully used for finishing the high-precision rapid geocoding of the spaceborne SAR images on the premise of needing no iterative operation. Most of the traditional geocoding methods for the spaceborne SAR images need iterative operation, have low processing efficiency, affected positioning precision due to approximation processing in the operation, in particular has satellite velocity error which is the greatest factor affecting the precision of the traditional geocoding results of the spaceborne SAR images. The method of the invention is not affected by the satellite velocity error, when the ephemeris parameters are not very good, the positioning precision of the method is rather better than that of the traditional positioning method, thus the method is more applicable to the actual engineering application. The method is a brand-new positioning method of the spaceborne SAR images, and has great significance in realizing the rapid and high-precision geocoding of the spaceborne SAR images.
