  • Image processing method and apparatus, and image processing device using infrared binocular cameras to obtain three-dimensional data
    Patent number: 11461908
    Abstract: Disclosed are an image processing method and apparatus, and an image processing device. According to the image processing method and apparatus, and the image processing device, an infrared binocular camera collects images formed when a measured object is illuminated by a speckle pattern projected by a projection assembly to obtain a first image collected by a first camera and a second image collected by a second camera; and three-dimensional data of the measured object is determined according to a pair of images constituted by the first image and the second image. By means of the method, three-dimensional data of a measured object can be relatively accurately obtained through measurement, thereby improving precision and accuracy of measurement, and also precision requirements for a projection assembly are low, so that costs can be lowered.
