A multi-camera measuring system is a type of metrological (measurement) system that uses multiple cameras to measure the dimensions and features of an object. These systems are often used in manufacturing and quality control applications to ensure that parts or products meet specific tolerances and specifications.

The cameras in a multi-camera measuring system can be mounted on a stationary frame, or they can be mounted on a moving platform such as a robotic arm or ROV. The cameras are typically calibrated to ensure accurate measurements, and they are usually equipped with specialized lenses and filters to enhance the accuracy of the measurements.

The data collected by the cameras is typically processed by specialized software, which can compute the dimensions and features of the object being measured. This data can then be used to create detailed 3D models of the object, or it can be used to compare the object to a set of predetermined specifications.

Overall, multi-camera measuring systems are useful tools for ensuring the quality and accuracy of manufactured parts and products, and they are widely used in a variety of industries.
