    摘要: Structured light active sensing systems transmit and receive spatial codes to generate depth maps. Spatial codes can't be repeated within a disparity range if they are to be uniquely identified. This results in large numbers of codes for single transmitter/single receiver systems, because reflected ray traces from two object locations may be focused onto the same location of the receiver sensor, making it impossible to determine which object location reflected the code. However, the original code location may be uniquely identified because ray traces from the two object locations that focus onto the same location of the first receiver sensor may focus onto different locations on the second receiver sensor. Described herein are active sensing systems and methods that use two receivers to uniquely identify original code positions and allow for greater code reuse.

    摘要: The subject disclosure is directed towards detecting planes in a scene using depth data of a scene image, based upon a relationship between pixel depths, row height and two constants. Samples of a depth image are processed to fit values for the constants to a plane formulation to determine which samples indicate a plane. A reference plane may be determined from those samples that indicate a plane, with pixels in the depth image processed to determine each pixel's relationship to the plane based on the pixel's depth, location and associated fitted values, e.g., below the plane, on the plane or above the plane.

    摘要: A powerful, scalable, and reconfigurable image processing system and method for processing stereo image data is described. A general purpose, reconfigurable engine with toroidal topology, distributed memory, and wide bandwidth I/O is described for solving real applications at real-time speeds. The reconfigurable image processing system can be optimized to efficiently perform specialized computations, such as real-time video and audio processing. This reconfigurable image processing system provides high performance via high computational density, high memory bandwidth, and high I/O bandwidth. Generally, the reconfigurable image processing system and its control structure include a homogeneous array of 16 field programmable gate arrays (FPGA) and 16 static random access memories (SRAM) arranged in a partial torus configuration (Fig. 46). The reconfigurable image processing system also includes a PCI bus interface chip, a clock control chip, and a datapath chip. It can be implemented in a single board. It receives data from its external environment, computes correspondence, and uses the results of the correspondence computations for various post-processing, industrial applications. The reconfigurable image processing system determines correspondence by using non-parametric local transforms followed by correlation. These non-parametric local transforms include the census, and rank transforms. Other embodiments involve a combination of correspondence, rectification, a left-right consistency check, and the application of an interest operator.

    摘要: A method and system for registering data by first acquiring the data from a scene by a sensor at different viewpoints, and extracting, from the data, three- dimensional (3D) points and 3D lines, and descriptors associated with the 3D points and the 3D lines. A first set of primitives represented in a first coordinate system of the sensor is selected, wherein the first set of primitives includes at least three 3D points. A second set of primitives represented in a second coordinate system is selected, wherein the second set of primitives includes any combination of 3D points and 3D lines to obtain at least three primitives. Then, using the first set of primitives and the second set of primitives, the 3D points are registered with each other, and the 3D points with the 3D lines to obtain registered primitives, wherein the registered primitives are used in a simultaneous localization and mapping (SLAM) system.

    摘要: Methods and apparatus for making environmental measurements are described. In some embodiments different devices are used to capture environmental information at different times, rates and/or resolutions. Environmental information, e.g., depth information, from multiples sources captured using a variety of devices is processed and combined. Some environmental information is captured during an event. Such information is combined, in some embodiments, with environmental information that was captured prior to the event. Environmental depth model is generated in some embodiments by combining, e.g., reconciling, depth information from at least two different sources including: i) depth information obtained from a static map, ii) depth information obtained from images captured by light field cameras, and iii) depth information obtained from images captured by stereoscopic camera pairs. The reconciliation process may involve a variety of information weighting operations taking into consideration the advantages of different depth information sources and the availability of such information.
