Abstract: A system performs calibration of sensors mounted on a vehicle, for example, lidar and camera sensors mounted on a vehicle, for example, an autonomous vehicle. The system receives a lidar scan and camera image of a view and determines a lidar-to-camera transform based on the lidar scan and the camera image. The system may use a pattern, for example, a checkerboard pattern in the view for calibration. The pattern is placed close to the vehicle to determine an approximate lidar-to-camera transform and then placed at a distance from the vehicle to determine an accurate lidar-to-camera transform. Alternatively, the system determines edges in the lidar scan and the camera image and aligns features based on real-world objects in the scene by comparing edges.

Abstract: A digital microform imaging apparatus, comprising a chassis, a fold mirror supported by the chassis and including a reflecting surface for directing light from a first substantially vertical optical axis to a second substantially horizontal optical axis, a microform media support structure supported at a location intersected by the first optical axis, a first carriage supported for movement along a trajectory that is substantially parallel to the second optical axis, an area sensor supported for movement along the second optical axis, the area sensor further supported by the first carriage for rotation about an axis parallel to the second optical axis and a lens supported for movement along the second optical axis, the lens positioned between the area sensor and the fold mirror, a first motor mounted to the first carriage and linked to the area sensor for rotating the area sensor between at least two positions for obtaining portrait and landscape images of a microform media.

Abstract: The invention is directed to a digital microform reader that has a form carrier. A light projection system projects light onto the form carrier. A digital imaging system images a portion of the form carrier. A computer communication data interface system receives an electronic image from the digital imaging system, wherein the digital microform reader does not contain a viewer. A light diffusion sheet may be used with a condenser lens of the light projection system. The digital imaging system includes a CMOS (Complementary Metal Oxide Semiconductor) detector. CMOS detectors are able to capture an image much faster than CCD (Charge Coupled Device) detectors. Because the system does not have a separate viewer it is much less expensive than prior art systems. The system also uses less energy than prior art machines because of its use of light diffusion sheets with the condenser lens and as a background for the microform.

Abstract: A system and method for storing documents in human and machine readable format. A laser scanner is used to write de-magnified visual copies and digital records of the documents in an optical recording medium. A table of contents and record headers are provided to ease document retrieval. The optical recording medium is made of materials which can be written directly by the laser scanner without the need for post-writing processing. The direct write characteristic allows immediate retrieval, and allows additional documents to be added to the optical recording medium at later times. The documents are retrieved from the optical recording medium by either magnifying the visual copies or by regenerating the documents in visual form using the digital information.

Abstract: A process and device for analyzing image data and performing automatic optimization of a black and white image created by a scanner. The process and device performs dynamic thresholding by approximating the information level and the background level at every pixel in the image, the threshold being calculated as a function of the background and information levels at that point, and a characterization process step comparing the pixel intensity at that point with the threshold, so that if the pixel is darker, it is considered to be black, or if it is lighter, it is considered to be white.

Abstract: An apparatus for digitally archiving analog film images includes a support surface on which an analog film image may be supported, and a digitizer that is spaced from the support surface in a direction defining a Z axis perpendicular to the support surface. A light transilluminates the film image and projects it toward the digitizer through an objective lens which focuses the image. The positions of the digitizer and the lens along the Z axis are adjustable so that the size of the image projected onto the digitizing means can be varied. For example, it is possible to move the digitizer and objective lens between a range of enlarging positions in which the lens is closer to the film image than to the digitizer, and a range of reducing positions in which the lens is further from the film image than from the digitizer so that the film image may be either enlarged, reduced or reproduced at the same size before being sensed and converted into digital data.
