Abstract: The invention relates to a method for more effectively capturing the three-dimensional surface geometry of objects, particularly for teeth and/or intraoral structures, such as when a scanning processing is interrupted. Depth images are created in which the spatial relationships of points of the depth images to one another remain constant, but an overall spatial orientation of each new depth image is different. Points of the depth image that fulfill a first attribute is verified for every pose. The number of points that have this attribute is then counted. The pose that accordingly has the highest count is thus chosen, and an artificial depth image is then generated, in which the ascertained pose is applied “backwards” to create an artificial depth image. The real new depth image can then be transferred into the artificial depth image in order to create a new pose, which may then be verified by computation.

As described below, a system may analyze images captured by a camera to identify objects that may be represented by the images. These objects may be identified in the images based on their size, color, and/or other physical attributes. After identifying these potential objects, the system may define a region around each object for further inspection. Thereafter, portions of a depth map of the environment corresponding to these regions may be analyzed to determine whether any of the objects identified from the images are “objects of interest”—or objects that the system has previously been instructed to track. These objects of interest may include portable projection surfaces, a user's hand, or any other physical object. The techniques identify these objects with reference to the respective depth signatures of these objects.

The determination of the motion vectors are based on two neighboring frames temporally located before and after the current frame. If the position of the current occlusion area is matched with the previous occlusion area by using one of the motion vectors, the neighboring area corresponding to the motion vector is designated as a foreground area.

Abstract: An automated method to quantify the pitching and yawing motion of a projectile during ballistic flight using two camera/tracker video systems. Image processing tools are used to segment the shape of the projectile in each frame of a launch video, which allows the location and observed pitch angle to be calculated with sub-pixel accuracy. Subsequent automated analysis uses the history of the projectile location and the pitching behavior to calculate estimates for the epicyclic motion, as well as other ballistic parameters such as aeroballistic coefficients. Using two cameras located at different orthographic views of the line-of-fire (LOF) allows the pitching and yawing motion history of the projectile to be calculated in three dimensions (3D). In addition, input of the camera locations, cannon trunnion location, and the cannon pointing direction allows for automatic correction for camera misalignment.
