The invention discloses a baseline distance adjustable scanning type automobile morphology detector based on a cylindrical pose benchmark, and aims to solve a problem of realizing automobile morphology scanning by adopting a baseline distance adjustable scanning method based on the cylindrical pose benchmark. The baseline distance adjustable scanning type automobile morphology detector based on the cylindrical pose benchmark is mainly composed of a cylindrical target (1), a T-slot guide rail (2), a laser demarcation device (3), a camera (4) inside the target, a camera (5) outside the target and a tripod (6). The baseline distance adjustable scanning type automobile morphology detector based on the cylindrical pose benchmark provided by the invention is small in occupied space, simple in structure, high in inspection accuracy, simple and convenient to operate, easy to install, low in cost and reliable in performance.
