Abstract: An image depicting an object has a center that is not on an optical axis of a camera used to capture the image. The image is on an image plane, and the object is in an object space. A method implemented for automatically determining the position of the camera relative to the object includes displaying the image via a user interface, receiving vanishing point information from the user interface, such that the vanishing point data indicates a respective location on the image plane of each of a first vanishing point, a second vanishing point, and a third vanishing point, and automatically determining the position of the camera based on the first vanishing point, the second vanishing point, and the third vanishing point.

Abstract: A method for determining a centerline for a triangulation-based optical profilometry system, compensating for the spatial variations of the reflectance of an object's surface. The method comprises providing a luminous line on the object, the luminous line being a triangulation line superposed with a compensation line; capturing an image of the triangulation line and of the compensation line; for each position along the imaged triangulation line, determining a transverse triangulation profile from the imaged triangulation line and a transverse compensation profile from the imaged compensation line; determining a transverse correction profile given by the reciprocal of the transverse compensation profile; multiplying the transverse triangulation profile with the transverse correction profile to obtain a corrected transverse triangulation profile; computing a center of the corrected transverse triangulation profile. The centers determined at positions along the triangulation line form the centerline.

Abstract: A camera of a computing device can capture two or more images of a region including an object of interest, in order to allow for separation of the object from a background of the images through a process such as image subtraction. In order to compensate for rotations of the device between image captures, an element such as an electronic gyroscope can be used to monitor changes in orientation and predict an amount of shift of objects between images. The predicted shift can be used to attempt to align images captured around the time of the rotation, in order to enable subtraction or similar processes by effectively removing the shifting effect of the rotation.

Abstract: Embodiments alter the swoop trajectory depending on the terrain within the view of the virtual camera. To swoop into a target, a virtual camera may be positioned at an angle relative to the upward normal vector from the target. That angle may be referred to as a tilt angle. According to embodiments, the tilt angle may increase more quickly in areas of high terrain variance (e.g., mountains or cities with tall buildings) than in areas with less terrain variance (e.g., flat plains). To determine the level of terrain variance in an area, embodiments may weigh terrain data having higher detail more heavily than terrain data having less detail.

Abstract: A method utilizing image correlation to determine position measurements in a machine vision system. In a first operating state, the machine vision system utilizes traditional scale-based techniques to determine position measurements, while in a second operating state, image correlation displacement sensing techniques are utilized to determine position measurements. The image correlation techniques provide for higher accuracy for measuring distances between features that are separated by more than one field of view. The user may toggle between the operating states through a selection on the user interface, and guidance may be provided regarding when the image correlation mode is likely to provide higher accuracy, depending on factors such as the distance to be measured and the characteristics of the surface being measured.

The difference is indicative of a change in perceived depth by a viewer.
