    摘要： A three dimensional model method based on combination of ground based images and images taken from above. An existing 3D model based on images taken from above is matched with images taken from ground level. All images including information about position and attitudes of the camera when the images from ground level and the images taken from above were taken and direction of each pixel. The method offers an automatically carried out imaging solving or at least mitigating occlusion problems.

    摘要： An air/fuel ratio controller (6) and a method that uses an upstream control loop to maintain a given optimum air/fuel ratio (λopt), whereas the optimum air/fuel ratio (λopt) is determined in the controller (6) in an downstream control loop by adding incremental offset (Δλ) to the air/fuel ratio set-point (λSP) of an upstream control loop while monitoring a NOx sensor (10) output. The air/fuel ratio set-points (λSP) at two turning points (SP1, SP2) in the NOx sensor (10) output are used to calculate a new optimum air/fuel ratio set-point (λopt) as mean value of the air/fuel ratio set-points (λSP1, λSP2) at the turning points (SP1, SP2).

    摘要： An automated three dimensional mapping method estimating three dimensional models taking advantage of a plurality of images. Positions and attitudes for at least one camera are recorded when images are taken. The at least one camera is geometrically calibrated to indicate the direction of each pixel of an image. A stereo disparity is calculated for a plurality of image pairs covering a same scene position setting a disparity and a certainty measure estimate for each stereo disparity. The different stereo disparity estimates are weighted together to form a 3D model. The stereo disparity estimates are reweighted automatically and adaptively based on the estimated 3D model.
