The development and deployment of compact ROVs (remotely operated underwater vehicles) in recent years have immensely helped users overcome the technical difficulties and efficiency issues of small-scale, underwater tasks. Professional activities like 4K filming, day-to-day aquaculture operations and deep-sea operations have been bolstered by innovations in this sector.

While the ROVs' capacity in shooting, mobility and power are continuously improving, the ability to accurately and actively lock onto subjects visually underwater has remained a challenging bottleneck within the industry. In light of recent breakthroughs and developments, QYSEA Technology has launched an AI-based vision platform allowing its FIFISH underwater robots to achieve precise underwater active visual locking capabilities.

The newly-developed QYSEA AI platform includes a range of adaptive position and vision locking systems for all FIFISH ROVs. Among these dynamic features, the AI vision lock system can visually secure onto selected targets across any underwater environment with ease and precision. The user needs to simply press on the area of interest on their APP screen and the ROV then intuitively adjusts its position, locking the target at the screen centre.

Activating the AI vision lock unleashes a range of smart capabilities that ensure selected subjects are at the main focus, improving operating efficiency and resistance against currents for the FIFISH user. Once locked onto the selected target and if the posture of the ROV – such as its pitch, direction and rolls – is changed from outside elements or thought the controller, the FIFISH will intuitively re-adjust its position towards the original point of focus.

The key technology behind QYSEA's AI platform is the dead reckoning inertial navigation system (DR-INS). FIFISH ROVs utilise their built-in accelerometer and gyroscope to measure the acceleration and angular velocity of objects, as well as their computing systems to actively estimate and calculate the position, attitude and velocity of objects in motion which results in a stabilised and smooth real-time target locking. QYSEA's AI platform and vision lock system brings disruptive and essential changes across the marine industries, further enhancing the capabilities for the needs of both professionals and enthusiasts.

ROVs gaining ground in aquaculture

Aquaculture in China has developed rapidly, ranking first in the world for more than 20 consecutive years and accounting for nearly 70 percent of the world's total output. However, its rapid development has also been accompanied by various challenges; traditional fish farming operations have relied on labour-intensive methods for inspections, as well as harmful breeding practices to manage its efficiency. Deploying compact ROVs into the world of aquaculture has greatly reduced human-based and fish-breeding risks. With the recent AI vision lock upgrade, the FIFISH can quickly locate and lock onto damaged areas around the fishing net and execute a quick repair with the net patch kit add-on tool. Through these modernised methods, the marine industry is able to experience immense improvements in its standards and operations.

The marine applications and scenarios where the FIFISH can benefit the user are not only limited to aquaculture. The QYSEA's AI vision lock platform introduces a new level of operational efficiency and capabilities for its ROV users. From underwater filming and discovery missions to advanced operational tasks, QYSEA's latest comprehensive APP upgrade pushes the industry of compact ROVs to new and exciting heights.
