Abstract
Изобретение относится к области обработки данных, в частности к обработке телематических данных, получаемых от телематического устройства транспортного средства (ТС) для целей построения карты его маршрута. Техническим результатом является повышение точности формирования маршрута движения ТС с привязкой к цифровой карте. Заявленный результат достигается за счет осуществления способа построения карты маршрута ТС на основе данных телематики, который содержит этапы, на которых получают на вычислительном устройстве данные по меньшей мере от одного телематического устройства ТС, включающие, по меньшей мере, скорость, географические координаты, обороты двигателя ТС, значение снижения точности (DOP), вектор движения (ВД) и время фиксации указанных параметров в точках маршрута; определяют для каждой точки маршрута ВД и DOP, причем если по меньшей мере для одной точки маршрута ВД и DOP отсутствуют, то для данной точки присваивается ВД и DOP известной следующей точки маршрута; выполняют фильтрацию точек маршрута, для которых показатель DOP в горизонтальной плоскости выше заданного значения, а также точек, для которых отличие ВД выше заданной погрешности по отношению к ВД для соседних точек; формируют набор отфильтрованных точек маршрута ТС; определяют радиус нахождения ТС в географической области на основании, по меньшей мере, показаний DOP для каждой точки из отфильтрованного набора; осуществляют нормализацию данных с помощью обогащения отфильтрованного набора точек маршрута точками с усредненным DOP и скорости движения ТС; осуществляют наложение нормализованных данных на цифровую карту и формируют карту маршрута ТС с привязкой к цифровой карте.The invention relates to the field of data processing, in particular to the processing of telematic data received from a telematics device of a vehicle (TC) for the purpose of constructing a map of its route. The technical result is to improve the accuracy of the formation of the route of movement of the vehicle with reference to a digital map. The claimed result is achieved by implementing a method for constructing a vehicle route map based on telematics data, which contains the stages at which data from at least one vehicle telematics device is received on a computing device, including at least speed, geographic coordinates, vehicle engine speed , the value of the reduction in accuracy (DOP), the motion vector (VD) and the time of fixing the specified parameters at the points of the route; determine for each point of the route the air pressure and DOP, and if for at least one point of the route the air pressure and DOP are absent, then for this point the air pressure and DOP of the known next route point are assigned; filtering route points for which the DOP in the horizontal plane is higher than a predetermined value, as well as points for which the difference in VD is higher than a predetermined error in relation to VD for neighboring points; form a set of filtered points of the vehicle route; determining the radius of the vehicle in the geographic area based on at least the DOP readings for each point from the filtered set; normalizing the data by enriching the filtered set of route points with points with an averaged DOP and vehicle speed; overlaying the normalized data on the digital map and forming the vehicle route map with reference to the digital map.
