Abstract
A measuring system for a 3D object includes a base, a horizontal scanning device disposed on the base, a first light emitting device, a second light emitting device, an image capture device, and a control device. The first light emitting device, the second light emitting device, and the image capture device are connected to the horizontal scanning device. The control device controls the horizontal scanning device to cause planar motion relative to the base. With the control of the control device, the first light emitting device and the second light emitting device alternate in projecting a light source onto a 3D object. The image capture device includes a double-sided telecentric lens to capture a plurality of images of the 3D object when the light source is projected onto the 3D object.
