Abstract

The present invention discloses a method for positioning a moving target based on a camera pitch, including: obtaining a vehicle trajectory of a moving target in a to-be-detected video and performing coordinate conversion; performing positioning correction on vehicle trajectory by using error correction method, to obtain final vehicle positioning, where a positioning correction process includes: obtaining a camera height and a camera pitch, constructing a relationship between camera height and camera pitch and a coordinate conversion error, calculating a coordinate conversion error, and calculating a target actual vehicle location based on the coordinate conversion error, to obtain vehicle positioning coordinates. In the present invention, a theoretical relationship between positioning error and camera installation height and angle is deduced based on an imaging principle and a geometrical projection relationship of an optical lens of the camera, so as to perform accurate error correction to implement high-precision positioning of a moving target.
