Underwater Inspection Process

Because of the nature of work at various depths and currents and weather , operations require constant monitoring for safety and integrity. To achieve this, operators need to place equipment at specified points in the water in order to obtain surface views. Or hire dedicated professional certified divers.

The first and most basic thing to look at is the integrity of the ship. This entails a thorough visual inspection. This part of the inspection is performed by an inspector diving down through the water to the bottom. The inspector must go through all of the same processes of regular operations. So, at any given time, at least one person is down at the bottom and a crew is up above monitoring the situation. And don’t forget about all the regulations and scheduling time and resource commitments. The equipment is needed to ensure that the human does not enter water at too high a pressure or current or wind and risk an environmental hazard or human casualty.

The ability to inspect with more accuracy and quicker, compared to human sight f. Faster automated processing. G. Thermal and sonar complex analysis humans are incapable of doing.

Why does machine vision and AI help visual inspections?

The good news is that visual inspection has been around for centuries, first with people and animals , next with Audio and video cameras. It was at first considered too expensive and too complex for visual inspection to become the mainstream. However, as the inspection technology started to be integrated with modern visualization, automation and industrial control systems, AI-based technology in visual inspection and robotics have started to become widely popular. The bad news is that most of the machine vision and AI tools have limitations in the quality of the inspection they can provide. The good news is Pagarba solutions is the visual inspection intelligence experts.

Image recognition basics

Image recognition is a technique for automatically identifying the objects in an image and then classifying those objects into segments , categories and metadata. High definition images and objects are represented using pixel values. Image recognition algorithms can extract pixel values that represent an object or a color and can identify those pixel values.

A common approach is to employ a convolutional neural network to perform image recognition. Convolutional neural networks are a computational structure that learn to map features to representations of the object or the color. Neural networks can also be categorized into convolutional neural networks, net-based convolutional neural networks, and Recurrent Neural Networks amongst many more.

Visual inspection Object detection basics

For smart manufacturing applications, real-time visual inspection is a significant application of image-based machine vision. There is a wide variety of inspection solutions that can be implemented in a smart manufacturing environment. The most common inspection systems utilize the live image of a physical asset to perform a visual inspection. Each single-camera-based inspection system includes components that can: a. adjust object focus; b. remove foreground objects; c. correct for lighting; d. correct for exposure; e. correct for scene shape and contrast. The above are general image-based inspection systems, as defined by ISO/IEC 14443:2008.
