Abstract

The invention discloses a vehicle classification detection method based on an optimized YOLOv5 model. The method comprises the steps of obtaining road traffic vehicle image data; performing vehicle type division on the road traffic vehicle image data to establish a vehicle identification detection data set; according to the vehicle identification detection data set, constructing an OP-YOLOv5 vehicle classification detection model; and inputting to-be-detected image data into the OP-YOLOv5 vehicle classification detection model to obtain a detection result. According to the invention, the precision and speed of vehicle detection are improved.

Description

technical field [0001] The invention relates to the technical field of target recognition, in particular to a vehicle classification and detection method based on an optimized YOLOv5 model. Background technique [0002] In recent years, with the rapid development of the economy, the number of automobiles in the country has increased rapidly.
