This document is a user manual for the QYSEA Laser Scaler, an accessory designed for underwater measurement in conjunction with FIFISH Remotely Operated Vehicles (ROVs).
Function Description
The Laser Scaler is an accessory that provides a visual reference for underwater measurements. It projects two parallel laser points, 10 cm apart, onto an object, allowing users to estimate or measure the size of objects captured by the ROV's camera. This feature is particularly useful for scientific research, inspection, and other underwater tasks where accurate sizing is required. The device integrates with the FIFISH APP interface, where users can select the Laser Scaler widget to activate and utilize its functionality. When the ROV is switched to 'S' (Sport) mode, the Laser Scaler can be used to measure objects from multiple angles, enhancing its versatility.
