Abstract

Translated fromRussian

Способ, системы и устройства для осуществления усовершенствованной трилатерации на основе местоположения включают прием информации о местоположении (например, точки траектории) с одного или нескольких внешних устройств, определение достоверности принятой информации о местоположении, выполнение операций нормализации для нормализации принятой информации о местоположении, присвоение общего рейтинга и рейтинга, зависящего от конкретного устройства, информации о местоположении и сохранение достоверной и нормализованной информации о местоположении в запоминающем устройстве. Усовершенствованная трилатерация на основе местоположения также может содержать выбор четырех местоположений (например, точек траектории) из запоминающего устройства на основании сочетания общего рейтинга и рейтинга, зависящего от конкретного устройства, и генерирование значения конечного местоположения или точки траектории на основании результата применения четырех выбранных точек траектории к фильтру Калмана. Выходные данные из фильтра Калмана также могут быть предоставлены и/или использованы в качестве текущего местоположения устройства.Method, systems and devices for implementing improved location based trilateration include receiving position information (eg, trajectory points) from one or more external devices, determining the reliability of received position information, performing normalization operations to normalize received position information, assigning an overall rating and rating, depending on the specific device, location information and the preservation of reliable and normalized information about m There is a location in the storage device. Advanced location-based trilateration can also include selecting four locations (for example, track points) from a storage device based on a combination of an overall rating and a device-specific rating, and generating a final location value or path point based on the result of applying four selected path points to Kalman filter. The output from the Kalman filter can also be provided and / or used as the current location of the device.
