Fishmetrics proposes an alternative solution based on a sophisticated, portable, digital measurement system using computer vision and non-contact 3D metrology solutions, and a back-end server which aggregates all sampling databases and automates all the required statistical analysis. > more

Automatic Acquisition System
Fishmetrics' Automatic acquisition system consists of a device placed over a box of unit responsible for the acquisition of the data (2D and 3D images of the fish), composed of an RGB camera, a depth sensor and a computer. The system uses infrared light, thus is non-damaging for the fish. The automatic system uploads the data to a remote database, where samplers can access the data and measure the fish. This cloud application can also store all the relevant metadata, including the fish species, vessel identification, capture location, fishing gear and more.

Manual Acquisition System
Fishmetrics' Manual acquisition system is a tablet application running on a iPad device incorporated with a depth sensor. The device captures pictures of the fish in any situation allowing the instant measurement of the specimen.

Fishmetrics Systems Cloud
This is Fishmetrics' remote database unit, into which images captured from the automatic and manual system are uploaded. In this browser application, users can select the fish samples, classify the specimens, measure them, assign measurement tasks to remote samplers, generate detailed reports and compute detailed statistics on the data.

Artificial Intelligence
Fishmetrics developed algorithms for the identification of fish species and size using neural networks and artificial intelligence. The outline of the fish can also be determined. This paves the way for a fully automatic solution that is able not only to capture pictures of the landed fish, but also to automatically measure it instantly, which allows the creation of very large samples of data, reducing operation costs.

MEDUSA: A compact underwater stereo vision system for measuring fish
In the context of aquaculture, fish length is a key parameter to assess fish stocks, essential for feeding regime and contributes for decisions at several production levels. However, taking length measurements is a cumbersome task that, when applied to living individuals, can induce considerable stress, increasing the risk of damage or hindering their growth. Computer vision is one of the most used non-contact tools to overcome this issue, being fast, consistent and repeatable. However, its use in aquatic environments is limited by the high cost, the difficulty of calibrating the system in underwater conditions and the complexity of implementation. FISHMETRICS proposes a low-cost easy-to-use vision system MEDUSA that can take measurements on live fish in aquatic conditions, without the need for a special calibration and a demanding image analysis service. Given some structural conditions such as a short baseline, the system is able to measure fish with an error of less than 1%. The short baseline allows to have a compact system and reduces the effect of water refraction on the 3D reconstruction. > Learn more.
