Target object measurement method and device, measurement equipment and storage medium

The invention discloses a target object measurement method and device, measurement equipment and a storage medium, and the method comprises the steps: obtaining observation point data and camera posture data of the measurement equipment when a target object is photographed at at least two photographing positions; determining first pose information of the measurement equipment in a space coordinate system at each shooting moment based on the observation point data and the camera pose data; determining first coordinate information of the target object in a space coordinate system at each shooting moment based on the first pose information and a camera observation equation; converting the first pose information into target pose information in a geodetic coordinate system based on the observation point data, and converting the first coordinate information into target coordinate information in the geodetic coordinate system; and performing point cloud modeling on the target object based on the target pose informat
