摘要： A reflecting stereoscope has picture holders and oculars for the observation of pictures held by the picture holders, and an optical train between the picture holders and the oculars. Picture marks and measuring markers carrying adjustable measuring marks are interposed in the optical train and there is a measuring device for measuring the location of the measuring marks. The picture holders are disposed in the focal plane of the oculars and a lens system on the optical axis of the oculars projects the magnified image of the measuring marks onto the focal plane of the oculars. Partially reflecting mirrors in the light path of the optical train observe picture marks and the measuring marks. A special system for moving the measuring markers and measuring their position is provided.

摘要： This invention describes an analog system for the automation of the stereocompilation process and for producing contour maps and orthophoto maps. It employs a combination of coherent optical and electronic techniques for the correlation of stereophoto pairs and thus the computation of parallaxes in the photogrammetric sense, for the selection of specific parallaxes, and for the production of contour maps and orthophoto maps.The system in a basic form reproduces perspective contours of the imagery, and in a more complete system corrects the perspective contours into orthographic contours and orthophoto-maps.

摘要： A structural analysis computing device for determining structural characteristics of an object pictured in a three-dimensional (3D) image may be provided. The structural analysis computing device may include a memory, a user interface, an object sensor configured to capture the 3D image of the object, and at least one processor in communication with the memory and the object sensor. The processor may be configured to access the 3D image including the object, automatically determine a first plurality of measurements of the object from the 3D image, and display the 3D image on the user interface. The processor may be further configured to generate a data file including the 3D image and the first plurality of measurements, and store the data file within the memory. The processor may also be configured to transmit the data file to an insurance server computing device for generation of an associated insurance claim form.

摘要： The present invention relates to a tracker and a surveying apparatus comprising the tracker, which improve the reliability of tracking a target. The tracker comprises a first imaging region having a plurality of pixels for taking a first image of a scene including the target; a second imaging region having a plurality of pixels for taking a second image of a scene including the target; a control unit to receive a timing signal indicating a time duration during which an illumination illuminating the target in the scene is switched on and off, control the first imaging region to take the first image of the scene when the timing signal indicates that the illumination unit is switched on, and control the second imaging region to take the second image when the illumination is switched off; and a read out unit configured to read out the first image from the first imaging region and the second image from the second imaging region and to obtain a difference image.

摘要： Embodiments of the invention provide a camera array imaging architecture that computes depth maps for objects within a scene captured by the cameras, and use a near-field sub-array of cameras to compute depth to near-field objects and a far-field sub-array of cameras to compute depth to far-field objects. In particular, a baseline distance between cameras in the near-field subarray is less than a baseline distance between cameras in the far-field sub-array in order to increase the accuracy of the depth map. Some embodiments provide an illumination near-IR light source for use in computing depth maps.

摘要： A method for detecting a displacement of a mobile platform includes acquiring a first frame and a second frame using an imaging device coupled to the mobile platform, obtaining an angle of the imaging device relative to a reference level while acquiring the first frame, and determining the displacement of the mobile platform based at least on the first frame, the second frame, and the angle of the imaging device relative to the reference level.

摘要： A method for generating an optical marker for image processing/photogrammetry/motion detection using an output unit and/or a control and/or regulation unit. The optical marker is output/generated in such a way that the represented optical marker is formed by a regular pattern of angular structures and by substructures, each of which is situated completely within one of the structures. In each case, at least two directly adjacent structures, viewed in at least two mutually perpendicularly oriented directions along a projection plane of the optical marker, have different colors, and a color sequence of the plurality of structures periodically repeats along the two directions. The optical marker is formed from unique minimum recognition areas within the optical marker. The optical marker is output/generated in such a way that the substructures each include an imaging surface that corresponds to at least 15% of a maximum projection surface spanned by one of the structures.

摘要： A pile head analysis system captures a plurality of images of a construction site including a pile using a camera mounted on an unmanned aerial vehicle (UAV), acquires the images, generates a three-dimensional model of the construction site, detects a pile head from the three-dimensional model, and determines consistency between the detected pile head and preliminarily acquired design information.
