The invention discloses a steel rail profile registration method, device and equipment and a storage medium, and relates to the technical field of rail dynamic measurement. The method comprises the following steps: acquiring a standard steel rail profile; a dynamic measurement result output by the laser sensor is obtained, and an actually-measured steel rail profile is obtained through preprocessing based on the dynamic measurement result; based on the rail waist area of the standard steel rail profile and the rail waist area of the actually-measured steel rail profile, rail waist profile rough registration is carried out in a geometric constraint and feature point registration mode, and a rough registration result is obtained; and on the basis of the coarse registration result, performing fine registration according to a preset rotation angle correction value range and a preset translation amount correction value range to obtain a final steel rail profile matching result. Rapid and accurate registration of the actually-measured steel rail profile and the standard steel rail profile is achieved, and the efficiency of steel rail profile registration in dynamic track detection is greatly improved.
