摘要： The present application relates to the field of automatic driving technology, and discloses a vehicle positioning method and device based on environment matching, a vehicle and a storage medium. The method includes: step S10: obtaining current environment data and a current road image of a location of a vehicle to be located; step S20: searching for an environmental impact road image set matching with the current environment data; step S30: matching the current road image with an environmental impact road image in the environmental impact road image set respectively to obtain a target environmental impact road image matching with the current road image; and step S40: determining current location information of the vehicle to be located based on the target environmental impact road image. Compared with the existing technology which mostly uses high-precision maps produced under sunny day conditions for carrying out vehicle positioning, ignoring positioning errors caused by weather and time periods, by means of the steps above, the mapping effects caused by different environmental factors is fully considered, thereby reducing positioning errors caused by environmental interference and improving vehicle positioning accuracy under different environmental conditions.
