  • Patent number: 11438520
    Abstract: A processor obtains an input image containing both bright and dark regions. The processor obtains a threshold between a first pixel value and a second pixel value of the display. Upon detecting a region of the input image having an original pixel value above the threshold, the processor can create a data structure including a location of the region in the input image and an original pixel value of the region. The data structure occupies less memory than the input image. The display presents the input image including the region of the image having the original pixel value above the threshold. The processor sends the data structure to a camera, which records the presented image. The processor performing postprocessing obtains the data structure and the recorded image and increases dynamic range of the recorded image by modifying the recorded image based on the data structure.

  • Patent number: 11054546
    Abstract: A system and method for measuring three-dimensional (3D) coordinates is provided. The method includes rotating a 3D scanner about a first axis, the 3D scanner having a light source, a light receiver and a color camera. A light beams are emitted from the light source and reflected light beams are received with the light receiver. A processor determines 3D coordinates of points on the object based on the emitted light beams and the reflected light beams. For each of the points an intensity value is measured based on the reflected light beams. A color image of the object is acquired with the color camera. The intensity values are fused with the color image to generate an enhanced image, the enhanced image includes color data. Color data is merged with the 3D coordinates of the points. The 3D coordinates of the points are stored with the color data.
