Method and apparatus for cleanliness determination of areas and objects via video monitoring

The present invention generally relates to assigning and reporting the cleanliness of objects and areas, and particularly relates to utilization of object and area cleanliness states as determined by the opposing processes of cleaning and dirtying detected through various methods to provide an indication of the state of cleanliness potentially utilized to alter the process of cleaning and/or dirtying to reach a desired state of cleanliness. Detection of the cleaning and dirtying operations can be performed automatically through image processing and behavior detection of still images/video indicating the activity taking place in the area of interest and time. The state of cleanliness can then be reported to interested parties as textual reports and/or augmented reality overlays on still images/video.

VIDEO INSPECTION METHOD FOR INSPECTING WELDS, STRUCTURAL BEAMS, AND UNDERDECKS OF MARINE VESSELS AND LIKE STRUCTURES

A method for inspecting a marine vessel underdeck utilizes a video camera such as a digital video camera with a magnifying or telephoto lens. The method produces a magnified image on a monitor for viewing by an inspector that appears to be no more than about 24 inches (61 cm) away. The method includes the step of filming the underdeck of a distance of about 40-70 feet (12-21 m). The lens provides a focal length of between about 15 feet (4.6 m) and 150 feet (46 m). Thus the method is conducted at a workable focal range of between about 15 feet (4.6 m) and 150 feet (46 m). The lens preferably has a focal length of between 30 feet (9 m) and 75 feet (23m). The method includes the step of scanning the suspect area of the underdeck of a speed of about 1 inch (2.54 cm) per second to three feet (91.4 cm) per second. The preferred method contemplates scanning of the suspect area of a rate of between about 0.5-1 foot (15.2-30.5 cm) per second. The digital video can be focused on a particular area for about 15-30 seconds to create a loop for vetting.

Surface defect monitoring system

A system for taking high-resolution photographs from a vehicle-mounted camera, forming orthomosaics from video and/or multiple high-resolution photographs, and using artificial intelligence to detect and classify pavement flaws and defects in the imagery. Detection also includes the ability to capture quantifiable metrics for the defects and/or a region of interest. Three-dimensional imagery is produced from the same images as the orthomosaics. Surface and terrain map products made from the same source images capture additional details such as depth and volume. The highlighted orthomosaics and three-dimensional imagery can then be used as a basis to determine the pavement surface condition and subsequently support maintenance orders and manage pavement repairs. Further, metadata such as latitude, longitude, and altitude geo-location coordinates and sampling time can also be transferred to the output products to create a digital time history and enable analysis for preventative maintenance planning. Alternatively-sourced imagery may also be analyzed.
