Abstract
An exemplary apparatus and associated method are disclosed for analyzing surface degradation. The apparatus can include a sensor configured to acquire images of a surface; and a processing device configured to correlate the acquired images to a geo-coordinate, to extract at least one property of a surface abnormality identified in at least one of the acquired images, and to generate trend data based on changes over time in the at least one property of the surface abnormality identified in the images, which are correlated to a common geo-coordinate.
Claims29
A system for analyzing a surface subject to degradation over time, comprising:
- a sensor configured to acquire at least one image of a surface;
- a first processing device configured to associate a time stamp and geo-coordinate data with each acquired image to identify when a surface abnormality is present in the at least one acquired image, and to select at least one of the acquired images which shows the abnormality in the surface;
- and
- a second processing device configured to extract at least one property of the surface abnormality identified in the at least one selected image, to store data representing the extracted property in a database, and to generate trend data of the surface by analyzing surface degradation over time based on the at least one property extracted from plural images correlated to a common geo-coordinate,
- wherein the second processing device is configured to generate trend data based on at least characteristic conditions of the surface including static characteristics of the surface in combination with at least one of dynamic and environmental characteristics associated with the surface and forecast a life-cycle of the surface abnormality based on the characteristic conditions of the surface and the at least one property extracted from the plural images.
An apparatus for analyzing surface degradation over time, comprising:
- a sensor configured to acquire images of a surface;
- and
- a processing device configured to correlate the acquired images to a geo-coordinate, to extract at least one property of a surface abnormality identified in at least one of the acquired images, and to generate trend data based on changes over time in the at least one property of the surface abnormality identified in the images, which are correlated to a common geo-coordinate,
- wherein the processing device generates trend data based on at least characteristic conditions of the surface including static characteristics of the surface in combination with at least one of dynamic and environmental characteristics associated with the surface and forecasts a life-cycle of the surface abnormality based on the characteristic conditions of the surface and the at least one property of the surface abnormality extracted from the at least one acquired image.
A method of identifying surface degradation, comprising:
- acquiring images of a surface from a sensor;
- associating the acquired images with geo-coordinate data;
- processing the acquired images to identify an abnormality in the surface and extract at least one property of the surface abnormality;
- generating trend data on a selected abnormality by analyzing changes over time in the at least one property extracted from images correlated to a common geo-coordinate, wherein the trend data is generated based on characteristic conditions including static characteristics of the surface in combination with on at least one of dynamic and environmental characteristics of the surface;
- and
- forecasting a life-cycle of the surface abnormality based on the characteristic conditions and the at least one property of the surface abnormality extracted from the acquired images.
A non-transitory computer readable medium having programming code recorded thereon such that when placed in communicable contact with a processor, the processor executes a method of measuring surface degradation over time comprising:
- acquiring at least one image of a surface;
- associating the at least one acquired image with geo-coordinate data;
- processing the at least one acquired image to identify an abnormality in the surface and to extract at least one property of the surface abnormality identified in the at least one acquired image using a wavelet transform;
- and
- generating trend data on the surface abnormality and forecasting a life-cycle of the surface abnormality by analyzing surface degradation over time based on the at least one property extracted from plural images correlated to a common geo-coordinate and characteristic conditions of the surface including static characteristics of the surface in combination with at least one of dynamic and environmental characteristics associated with the surface.
