The present disclosure describes systems and techniques relating to generating three dimensional (3D) models from range sensor data. According to an aspect, frames of range scan data captured using one or more three dimensional (3D) sensors are obtained, where the frames correspond to different views of an object or scene; point clouds for the frames are registered with each other by maximizing coherence of projected occluding boundaries of the object or scene within the frames using an optimization algorithm with a cost function that computes pairwise or global contour correspondences; and the registered point clouds are provided for use in 3D modeling of the object or scene. Further, the cost function, which maximizing contour coherence, can be used with more than two point clouds for more than two frames at a time in a global optimization framework.

The present invention provides a method and apparatus for adjusting stereoscopic image parallax and a stereo camera. The parallax adjusting method includes obtaining a depth range of a current scene. A preset parallax range may also be obtained according to a current viewing condition. Expected camera parameters of the current scene are calculated according to the depth range of the current scene and the preset parallax range. The stereo camera is adjusted according to the expected camera parameters and used to capture preprocessed stereoscopic images. Further, the captured preprocessed stereoscopic images are processed according to the expected camera parameters to make the preprocessed stereoscopic images suitable for being viewed under the current viewing condition. The disclosed method and apparatus can jointly adjust parameters of the stereo camera and captured stereo images to obtain images or videos with a maximum parallax as well as desired display effect under a specified condition.

Methods and apparatus provide for an automated system for analyzing damage to insured property. A server may receive images of a scene (e.g., a room, house, apartment, etc.) from a user at a mobile device. The server may analyze the images to create a holistic view of the scene. The server and/or mobile device may be able to generate dimensions of the scene and compare those dimensions to the dimensions of a damaged property at the scene to determine the extent of damage to the property. The server may also be able to detect gaps between images as it creates the holistic view of the scene.

Images captured at short distances, such as “selfies,” can be improved by addressing magnification and perspective effects present in the images. Distance information, such as a three-dimensional depth map, can be determined for an object using stereoscopic imaging or another distance measuring approach. Based on a magnification function determined for a camera lens, magnification levels for different regions of the captured images can be determined. At least some of these regions then can be adjusted or transformed in order to provide for a more consistent magnification levels across those regions, thereby reducing anamorphic effects. Where appropriate, gaps in the image can also be filled to enhance the image. At least some control over the amount of adjustment may be provided to users for aesthetic control.

A method and apparatus merge depth maps in a depth camera system. According to a possible embodiment, a first image of a scene can be received. The first image can include first image coordinates. A second image of the scene can be received. A third image of the scene can be received. An x-axis depth map of the first image coordinates can be generated based on the first and second images. A y-axis depth map of the first image coordinates can be generated based on the first and third images. The y-axis can be perpendicular to the x-axis. Edge detection can be performed on the first image to detect edges in the first image. A confidence score map can be generated for each depth map. A higher confidence score on the confidence score map of the x-axis depth map can be set for a pixel on an edge at an angle closer to the y-axis than the x-axis for the pixel on the x-axis depth map. A lower confidence score on the confidence score map of the y-axis depth map can be set for a corresponding pixel on the y-axis depth map. A depth value of a pixel on a fusion depth map can be selected based on the confidence score maps and the depth maps.

In an example embodiment, method, apparatus and computer program product are provided. The method includes facilitating receipt of first image (I1) and second image (I2) of a scene. Cost volume between images I1 and I2 for set of foreground labels (FL) and set of background labels (BL) is determined that includes matching costs of pixels in I1 and corresponding pixels in I2 for FL and BL. Reduced cost volume is determined from the cost volume, including matching costs of pixels in I1 and corresponding pixels in I2 for FL and a background label (L1) of BL, where matching cost of an individual pixel in I1 and corresponding pixel of the individual pixel in I2 for L1 includes minimum matching cost from a set of matching costs of the individual pixel for BL. A disparity map is generated by performing cost aggregation of the reduced cost volume in I1 and I2.

A stereo camera apparatus which carries out distance measuring stably and with high accuracy by making measuring distance resolution variable according to a distance to an object is provided. A stereo camera apparatus 1 takes in two images, changes resolution of a partial area of each image that is taken in, and calculates a distance from a vehicle to an object that is imaged in the partial area, based on disparity of the partial area of each image in which resolution is changed. Thus, even when the object exists at a long distance and is small in size, distance measuring processing can be carried out stably.

What is disclosed is system and method for contemporaneously reconstructing images of a scene illuminated with unstructured and structured illumination sources. In one embodiment, the system comprises capturing a first 2D image containing energy reflected from a scene being illuminated by a structured illumination source and a second 2D image containing energy reflected from the scene being illuminated by an unstructured illumination source. A controller effectuates a manipulation of the structured and unstructured illumination sources during capture of the video. A processor is configured to execute machine readable program instructions enabling the controller to manipulate the illumination sources, and for effectuating the contemporaneous reconstruction of a 2D intensity map of the scene using the second 2D image and of a 3D surface map of the scene using the first 2D image. The reconstruction is effectuated by manipulating the illumination sources.
