20140293081 | COMPUTING DEVICE AND METHOD OF IMAGE MATCHING - A computing device is connected to a measurement device including a projector, a left camera and a right camera. The projector is controlled to project gratings with a number M of frequencies on an object. The left camera captures a number N of left grating images, and the right camera captures a number N of right grating images of the gratings with each of the frequencies. A luminous intensity of each pixel in each of the left grating images and the right grating images is computed. According to the luminous intensity of each pixel in each of the left grating images, a first phase grayscale image is obtained. According to the luminous intensity of each pixel in each of the right grating images, a second phase grayscale image is obtained. A matched image is obtained by matching the first phase grayscale image and the second phase grayscale image. | 10-02-2014 |
