摘要： The invention relates to a system and process for generating a two-dimensional stitched and annotated digital image of a site having at least one as-built structure thereon. The process includes acquiring a plurality of digital images, still frames and/or video images of the site, the structure, or both, with each of the digital images including one or more reference objects positioned on or about the site, the structure, or both. The reference objects are configured to accurately scale and orient each of the digital images. The process photogrammetrically generates a three-dimensional point cloud from the digital images, and one or more reference objects and features of interest are identified in the three-dimensional point cloud. Based on the identified reference objects and features, the process and system generates the two-dimensional stitched and annotated digital image of the site and/or the structure.

摘要： A method of determining at least one of position and attitude in relation to an object is provided. The method includes capturing at least two images of the object with at least one camera. Each image is captured at a different position in relation to the object. The images are converted to edge images. The edge images of the object are converted into three-dimensional edge images of the object using positions of where the at least two images were captured. Overlap edge pixels in the at least two three-dimensional edge images are located to identify overlap points. A three dimensional edge candidate point image of the identified overlapped points in an evidence grid is built. The three dimensional candidate edge image in the evidence grid is compared with a model of the object to determine at least one of a then current position and attitude in relation to the object.

摘要： The present invention provides a method for implementing high-precision orientation and evaluating orientation precision of a large-scale dynamic photogrammetry system, including steps: a) selecting a scale bar, arranging code points at two ends of the scale bar, and performing length measurement on the scale bar; b) evenly dividing a measurement space into multiple regions, sequentially placing the scale bar in each region, and photographing the scale bar by using left and right cameras; d) limiting self-calibration bundle adjustment by using multiple length constraints, adjustment parameters including principal point, principal distance, radial distortion, eccentric distortion, in-plane distortion, exterior orientation parameter and spatial point coordinate; and e) performing traceable evaluation of orientation precision of the photogrammetry system. The present invention can effectively reduce the relative error in length measurement.

摘要： An objective is to provide a body measurement device capable of carrying out a body measurement, such as of abdominal girth or chest girth, with a simple configuration which eliminates moving components. This body measurement device comprises: light projection devices which project linear light beams so as to encircle a measurement subject within a measurement plane; image capture devices which are positioned on the perimeter of the measurement subject such that the total circumference of the linear light beams which are projected upon the measurement subject are captured, and the optical axis of each respective image capture optical assembly is positioned in an oblique direction with respect to the measurement plane; a database which, with the measurement plane divided into respective measurement ranges of the image capture devices, associates two-dimensional coordinates with respect to captured images of the image capture devices with two-dimensional coordinates with respect to the measurement plane; and a computing device which, with the measurement plane divided into the respective measurement ranges of the image capture devices, queries the database from two-dimensional coordinates of a point with respect to the linear light beams with respect to the captured images of the respective image capture devices corresponding to the measurement plane, identifies two-dimensional coordinates with respect to the measurement plane, and computes a circumference of a body surface of the measurement subject with respect to the measurement plane.

摘要： A three-dimensional optical model is created from a stereo-pair of aerial photographs by projecting the photographs by means of two projectors, and a moving aperture scans the optical model. A photosensitive film is exposed to one of these beams and is shifted in a direction perpendicular to the plane of the film so that the portion of film that is being exposed intersects the optical model. Superimposed on the vertical shift motion of the film is a displacement tangential to the plane of the film, the amount of displacement being in a preselected relationship to the extent of the vertical shift.

摘要： Systems and methods related to an image capture process using ring paths may include traversing a user device around a ring path in a center of a room, capturing imaging data using the user device during the traversal, and processing the imaging data using photogrammetry. The imaging data may be captured using an imaging sensor associated with the user device, and the imaging data may be processed based on data received from position and orientation sensors associated with the user device. In addition, a three-dimensional model of the room may be generated based on the imaging data.
