The present invention provides an apparatus and a method for detecting a piping alignment using image information and laser sensors capable of precisely and accurately measuring and aligning the alignment of the entire pipes. The apparatus includes: a fixed plate installed on a base stage and having a reference pipe located thereon; a movable plate installed on the base stage along three axes to face the reference pipe and has an aligning pipe located thereon; a circular stage installed between the reference and aligning pipes and is configured to rotate and move along three axes so as to detect levelness and deformations of the reference and aligning pipes; a laser sensor and an imaging device installed on an upper side of the circular stage; and a controller configured to control the laser sensor and the imaging device and determine an alignment of the aligning pipe.
