Method for improving 2D frame positioning precision based on vehicle identification

The invention discloses a method for improving 2D frame positioning precision based on vehicle identification, and the method comprises the following steps: setting an observation point in front, and setting a camera at the observation point; recognizing image information of a rear coming vehicle through a camera; according to the image information, the outline of the rear coming vehicle is judged; a rectangular detection frame attached to the outline is arranged on the outer side of the outline; setting the coordinates of the upper left corner of the rectangular detection frame as (x1, y1); setting parameters for representing a rectangular detection frame; the invention relates to the technical field of vehicle identification, and the method for improving the 2D frame positioning precision based on vehicle identification can better assist a system to judge the actual position of a vehicle and the midpoint of the vehicle through cooperation with external hardware and setting of different types of functions in a program, is more accurate compared with a traditional judgment form, and improves the positioning precision of the 2D frame. Deviation and errors are prevented, it is guaranteed that a driver does not have the situation of misjudgment of coming vehicles, and the life safety of the driver is better guaranteed.
