EFFICIENT STORAGE OF HIGH-RESOLUTION INDUSTRIAL ULTRASONIC DATA
A method and device for processing ultrasonic data from an industrial inspection device. Ultrasonic reflections from a high-resolution phased array are sampled at high-frequency to create a large volume of data. The data are converted to I/Q data and compressed to a manageable size. An external computer can beamform and render an image without restoring the compressed data to raw form. This method may be used for in-line inspection, downhole inspection, or ultrasonic testing.
DETECTION OF STRUCTURES
A method for detecting structures is provided. The method can include receiving inspection image data characterizing a region of interest of an object being inspected. The regions of interest can include one or more structures of the object. The method can also include determining, using a computer vision algorithm, a structure within the region of interest with respect to photometric properties of pixel data in the inspection image data. The structure can be determined using a predictive model trained to determine image filter parameter values for image filters of the computer vision algorithm based on applying optimization techniques using training image data and annotation data. An indication of the structure can be provided, for example for display or storage in memory. Systems and computer-readable mediums implementing the method are also provided.

Automated supervision and inspection of assembly process
A method and apparatus for performing automated supervision and inspection of an assembly process. The method is implemented using a computer system. Sensor data is generated at an assembly site using a sensor system positioned relative to the assembly site. A three-dimensional global map for the assembly site and an assembly being built at the assembly site is generated using the sensor data. A current stage of an assembly process for building an assembly at the assembly site is identified using the three-dimensional global map. A context for the current stage is identified. A quality report for the assembly is generated based on the three-dimensional global map and the context for the current stage.
APPARATUS AND METHODS FOR INSPECTING OBJECTS AND STRUCTURES WITH LARGE SURFACES
Continuous, multiple-point surveying or measurement is performed on large areas or objects. The results may be coordinated or combined with 3D localization systems or methods employing GPS, manual theodolites, range finders, laser radars or pseudolites. One disclosed example describes the use of the invention as applied to the problem of routine and repeated inspection of large aircraft, though the system and method are equally applicable to other objects with large surfaces including ships, bridges and large storage structures like tanks, buildings, and roadways.
