Abstract: A workpiece measuring apparatus and a method for measuring a workpiece are provided. A first image of a first portion of a workpiece is captured, and a first location of the first portion is determined. A second image of a second portion is captured that is selected according to the first location and the location of a portion of the workpiece to be measured, and a second location of the second portion is determined. If the second image determines that the first location is correctly determined, a workpiece holding unit is moved along the original direction; otherwise, the second image replaces the first image, and the workpiece holding unit is moved along a new direction. Also, a third image of a third portion of the workpiece is further captured to replace the second image, until the third image determines that the second location is correctly determined.

Abstract: A stereo display system including a plurality of projection apparatuses and a screen module is provided. The projection apparatuses project a plurality of image beams. The screen module is disposed in front of the projection apparatuses, wherein the image beams are transmitted toward the screen module. The screen module includes a light diffusion layer and a beam splitting layer. The light diffusion layer has at least one diffusion direction, and the light diffusion layer diffuses the image beams with a diffusion angle. The light diffusion layer is disposed between the beam splitting layer and the projection apparatuses, wherein each of the image beams is divided into a plurality of sub image beams by the beam splitting layer. The sub image beams of each image beam transmit with different angles, such that the image beams form a plurality of stereo image viewing zones after passing through the screen module.
