  "textContent": "A vehicle positioning method and apparatus are provided. The vehicle positioning method includes: obtaining measurement information within preset angle coverage at a current frame moment by using a measurement device, where the measurement information includes a plurality of pieces of static target information (201); determining, based on the measurement information, current road boundary information corresponding to the current frame moment (202); determining first target positioning information based on the current road boundary information, where the first target positioning information is used to indicate a location of a target vehicle on a road (203); determining road curvature information based on the current road boundary information and historical road boundary information, where the road curvature information is used to indicate a bending degree of the road on which the target vehicle is located (204); and outputting the first target positioning information and the road curvature information (205). This method can improve a confidence level and reliability of positioning information, and estimate a bending degree of a lane in which the vehicle is located. Therefore, vehicle positioning accuracy is improved.",
