摘要： An automatic exposure system for an imaging-based bar code reader. The automatic identification system includes: an aiming apparatus generating a beam to aid in aiming the system at a target object when the system is actuated; an imaging system including a pixel array, a focusing lens to focus an image of the target object onto the pixel array; and an automatic exposure system to determine an integration time for capturing an image of the target object. The automatic exposure system, determines an integration time by: projecting an aiming pattern on the target object and capturing an image of the aiming pattern; determining a target distance from the imaging system to the target object based on a location of the aiming pattern within the captured image; determining a gain-integration time product utilizing an equation wherein the gain-integration time product is a function of a predetermined target image brightness and the target distance; and determining the integration time by selecting a gain value and solving for integration time given the gain-integration time product.

摘要： An optical code reading system and method are provided for reading and decoding an optical code. The system includes a plurality of light sources, a color image sensor, a processor and a decoder. Each light source produces a unique wavelength/color of light to illuminate the optical code, such as a direct mark optical code. The image sensor detects the reflected light from the optical code and generates an integrated multi-colored image. The processor separates the integrated image into individual color channels, where each color channel includes data representative of the imaged optical code in one color. The processor analyzes the contrast for each color channel and determines which color channel has the optimum contrast. The data corresponding to the color channel having the optimum contrast is then decoded by a decoder.

摘要： A system for removing artifacts caused by x-ray reflective materials from an x-ray image of a patient's teeth. The system includes an x-ray source, an x-ray detector that captures several x-ray images, and a surface scanner that captures a surface scan of the patient's teeth. An image processor generates three-dimensional models from the optical surface data and the CT volumetric data. The models are resized and oriented to be of the same scale and orientation and then overlaid to create a combined data set. Data points that extend beyond the surface of the patient's teeth in the surface model are identified and may be removed if it is determined that they are artifacts. An artifact-reduced CT model is then displayed.

The image scanning device includes an optical system and an image sensor array (403, 603) for focusing a light beam and imaging the target. The device preferably includes an automatic focusing system for adjusting the position of the optical system in order to adjust the focal point, and thereby focus the image of the target onto the image sensor array. In one embodiment of the image scanning device, the distance is determined by analyzing a collimated aiming pattern formed by collimating the light beam. In another embodiment, the distance is determined by analyzing a speckle pattern caused by the speckle effect upon the light beam hitting the target.
