A 3D modeling system employing a commercially available structured light source is disclosed. The light source projecting a light stripe is swung manually across an object or a particular area of interest on the surface of the object. Under the illumination of the swinging light stripe, the object is imaged to produce a sequence of images. For each of the images, the position and orientation of the structured light source are independently and dynamically derived. From each of the images, a set of curvilinear points from the (deformed) projected line falling on the object or the area of interest are calculated in conjunction with a calibration model of the imager. The curvilinear points from all the images are merged to provide accurate and complete 3D data about the object or the area of interest.
