20090040322 | ENHANCING DIGITAL IMAGES USING SECONDARY OPTICAL SYSTEMS - Apparatuses and methods for enhancing a “primary” large format, digital, macro-image with “secondary” image data are provided. The secondary image data is collected utilizing one or more secondary optical systems having at least one electro-optical detector array (e.g., a CCD array) and a specific set of optical mirrors or optical prisms, arranged in such a way that the secondary optical systems extend the angular angle-of-view of the primary optical system and the resultant digital image in at least two opposing directions, for instance, in the left and right and/or fore and aft directions. The primary image data and the secondary image data may be distinct and/or may include portions that overlap with one another. Further, the primary image data and the secondary image data may be collected at the same or different resolutions. The collected primary image data and secondary image data are utilized to generate a single output image. | 02-12-2009 |

20140267351 | MONOCHROMATIC EDGE GEOMETRY RECONSTRUCTION THROUGH ACHROMATIC GUIDANCE - Many imaging scenarios involve an achromatic image (e.g., a panchromatic image or a near-infrared image) and one or more concurrently captured monochromatic images (e.g., RGB images captured through a Bayer filter array), and the compositing of these images through de-mosaicing and/or pan-sharpening to generate a high-resolution color image. However, in many such scenarios, the monochromatic images may exhibit distortion of edge geometry, resulting in artifacts and/or color distortions near visual edges of the composite image. However, such distortions may be absent from the achromatic image, and edge geometry may be represented as an intensity gradient among respective neighborhoods of achromatic pixels. Presented herein are techniques for reducing such distortions in monochromatic images through iterative adjustment of monochromatic pixel intensity to reflect the gradients of the neighborhoods of the corresponding achromatic pixels. Convergence of such adjustments produces composite images exhibiting accurately reconstructed edge geometry. | 09-18-2014 |
20140300736 | MULTI-SENSOR CAMERA RECALIBRATION - One or more techniques and/or systems are providing for facilitating recalibration of a multi-sensor camera. That is, a multi-sensor camera may comprise a nadir sensor and one or more oblique sensors. Temperature, mechanical stress, and other factors can lead to misalignment of one or more sensors within the multi-sensor camera. Accordingly, a set of tie points and/or observations may be generated based upon a search matching technique, a densification technique, and/or a virtual matching technique. A bundle technique may be utilized to generate updated eccentricity information based upon the set of tie points and/or observations. The updated eccentricity information (e.g., orientation and/or position information of a sensor, such as an oblique sensor, with respect to a nadir view) may be used to recalibrate the multi-sensor camera, such as in real-time (e.g., during a flight mission that utilizes the multi-sensor camera to capture aerial images of a city or other scene). | 10-09-2014 |
20140368651 | MOBILE IMAGING PLATFORM CALIBRATION - Mobile platforms are used to capture an area using a variety of sensors (e.g., cameras and laser scanners) while traveling through the area, in order to create a representation (e.g., a navigable set of panoramic images, or a three-dimensional reconstruction). However, such sensors are often precisely calibrated in a controlled setting, and miscalibration during travel (e.g., due to a physical jolt) may result in a corruption of data and/or a recalibration that leaves the platform out of service for an extended duration. Presented herein are techniques for verifying sensor calibration during travel. Such techniques involve the identification of a sensor path for each sensor over time (e.g., a laser scanner path, a camera path, and a location sensor path) and a comparison of the paths, optionally after registration with a static coordinate system, to verify that the continued calibration of the sensors during the mobile operation of the platform. | 12-18-2014 |

20100183034 | SYNCHRONIZATION OF MULTI-TIME BASE DATA SOURCES - Systems and methods are described herein that cause data from asynchronous data sources to be provided with a timestamp that corresponds to a common time base.

Unsynchronized data sources can generate data independent of the trigger board. System timestamps are generated each time data from the synchronized data source and the unsynchronized data source is received. Values of the system timestamp can be modified, and can be replaced by timestamps that correspond to the time base used by the trigger board. | 07-22-2010 |
