Abstract: Systems and methods for evaluating the performance of three-dimensional (3D) sensors can include, for example, obtaining, via a 3D sensor in a testing apparatus, range information of a scene within a field-of-view (FOV) of the 3D sensor. The scene includes a plurality of targets disposed within the testing apparatus. Each of the plurality of targets is located at a different distance from the 3D sensor in the testing apparatus. A validation of the performance of the 3D sensor at the different distances is performed at a same point in time, based on the range information. An indication of a result of the validation is provided.

Abstract: A detection sensor to detect a receiving position of laser light according to the present invention includes a pair of light receiving element arrays (11X and 11Y), wherein adjacent light receiving elements (PDXi) are positioned as spaced equidistantly from one another and are mutually connected via a resistor (RXj), and wherein the output lines (11a and 11b) are respectively connected to the light receiving elements that are present at both ends of the respective light receiving element arrays (11X and 11Y). The light receiving element arrays (11X and 11Y) configure a composite array wherein the light receiving elements of a first light receiving element array are respectively positioned between the mutually adjacent light receiving elements of a second light receiving element array. When the laser beam makes contact with any of the light receiving elements, an analysis arithmetic device derives the position whereupon the laser beam is received, by performing a computation in accordance with the output that is obtained from each respective output line.

Abstract: Digitized stereo image pairs are analyzed by first aggregating the images to produce several levels of lower resolution images, bandpass filtering each of the images by applying a Laplacian filter to edge enhance the features, matching the features of low resolution images while generating a disparity image which contains elevation information, repeating the feature matching at successively higher resolutions and creating progressively improving disparity images, and extracting the elevation data from the final disparity image. The feature matching procedure uses an estimate of feature disparity to help locate a feature in one image which corresponds to a feature in another image and is applied iteratively at each level of resolution. Dilation of disparity data from matched points to neighboring unmatched areas produces a comprehensive disparity image which aids in more efficient feature location on the next pass.
