    摘要: The present invention provides a system and method (400) of generating a three-dimensional model of an object. The method (400) includes capturing first image and range data corresponding to a first portion of the object from at least two different positions (step 405) and generating a first three-dimensional model of the first portion of the object using the first image and range data (step 410). The method further includes capturing second image and range data corresponding to a second portion of the object from at least two different positions and generating a second three-dimensional model of the second portion of the object using the second image and range data (step 415). The first and second portions are overlapping. Finally, a third three-dimensional model is generated describing the first and second portions of the object by combining the first and second three-dimensional models into a single three-dimensional model (step 420).

    摘要: Disclosed is a structured light 3D scanner based on the principle of triangulation with a light source for generating a light pattern, two cameras with two-dimensional sensors recording the reflection of the light pattern from a target object, and one axis moving the cameras. Wherein the cameras are arranged with at least partly overlapping fields of view and where the sensors in the cameras are read out partially and concurrently during at least some period of the scanning process, thus providing partial images and where the partial images are merged prior to performing the triangulation calculations.

    摘要: Provided is a measurement method or apparatus that can reduce the time for measuring the shape of an entire test surface.
    Each of a plurality of measurement ranges is set so that one measurement range overlaps a portion of at least another measurement range to form an overlap region, each measurement range being a portion of the test surface. Then, the shape of the test surface is measured at a first resolution in a first measurement range among the plurality of measurement ranges, and is measured at a second resolution in a second measurement range. Pieces of data of the shapes of the test surface in the plurality of measurement ranges are stitched using the resulting measurement data to calculate the shape of the test surface,

    摘要: The invention relates to a method for determining a combined data record for an object to be measured using individual data records based on individual scans of the object, said scans being measured using at least one sensor. In order to avoid accumulating errors and allow individual data to be rectified or corrected, first partial scans of the object are measured using at least one first sensor and are aligned relative to one another and/or corrected using second partial scans performed by at least two second sensors that are stationary relative to one another, and the individual data records for the combined data record are determined from the aligned and/or corrected partial scans.

    摘要: The invention relates to generating a total data set of at least one segment of an object for determining at least one characteristic by merging individual data sets determined by means of an optical sensor moving relative to the object and of an image processor, wherein individual data sets of sequential images of the object contain redundant data that are matched for merging the individual data sets. In order that the data obtained by scanning the object are of sufficient quantity for performing an optimal analysis, but without being too great an amount of data for processing, the invention proposes that individual data sets determined per unit of time be varied as a function of the relative motion between the optical sensor and the object.
