Vehicle positioning method and apparatus, computer device, and storage medium

A vehicle positioning apparatus, comprising:

• at least one memory configured to store program code;
• and
• at least one processor configured to read the program code and operate as instructed by the program code, the program code comprising:
• obtaining code configured to cause at least one of the at least one processor to obtain odometer data from an odometer of a vehicle during driving;
• prediction code configured to cause at least one of the at least one processor to predict, and a first working state of a filter at a first moment, a second working state of the filter at a second moment based on the odometer data;
• and predict location information of the vehicle at the second moment based on the second working state;
• determining code configured to cause at least one of the at least one processor to select a target road section that matches the location information from candidate road sections in an electronic map, and determine matching point information corresponding to the location information in the target road section;
• and
• correction code configured to cause at least one of the at least one processor to correct the location information based on the matching point information, to obtain positioning information of the vehicle at the second moment, the positioning information and working states of the filter being defined in the same coordinate system.

A non-transitory computer-readable storage medium storing computer code which, when executed by at least one processor, causes the at least one processor to at least:

• obtain odometer data from an odometer of a vehicle during driving;
• predict, based on the odometer data and a first working state of a filter at a first moment, a second working state of the filter at a second moment, the second moment being after the first moment;
• predict location information of the vehicle at the second moment based on the second working state;
• select a target road section that matches the location information from candidate road sections in an electronic map, and determine matching point information corresponding to the location information in the target road section;
• and
• correct the location information based on the matching point information, to obtain positioning information of the vehicle at the second moment, the positioning information and working states of the filter being defined in the same coordinate system.
