The Counting Technology

The counter uses VAKI computer vision technology originally developed for counting fry, smolts and juvenile fish. Fish pass over a light source where an imaging line scanning camera is used to grab silhouette image of every single fish. The silhouettes are analysed and used for counting and size estimation.

Recording Of Images

The images of the fish are automatically recorded and can be used to validate and check the accuracy of the count. The image file can be given to a customer and / or stored as a permanent record.

The red chart indicates the numbers of fish counted during the entire count and is used to select a time frame for further analyses. The screen displays images of fish passing the camera for each one second interval. Accuracy can be verified by a manual check of the number of fish images to the count shown on the screen.

Macro App

Among other features the Macro app provides the user the option to run the counter, view the results and email the count report from a smart phone or tablet.

Counting Report

The automatic count report gives valuable and detailed information on the counting. The report can be supplied to the receiver of fish along with the counting file containing the images of all the fish. The throughput chart shows the rate of fish passing thru the counter. With this information the quality of the count can be assessed by checking for any overload time.

Size Measurements

An optional feature to the counting program, the size measurement module, presents accurate average weight and size distribution of the counted fish.
In one simple operation complete data on number and size of fish is obtained without handling or stress.

VAKI Smart Flow

The Smart Flow System gathers information from all devices. This facilitates the optimization of every grading/ counting operation as the various devices can be controlled and fine-tuned electronically in order to result in more precise controlled output.

VAKI Cloud

The VAKI Cloud is the online location to store and access all  your VAKI Counter Reports ,  fish images and smart flow grading reports. All VAKI Counters and Graders have the ability to automatically backup the files to VAKI Cloud.

With a secure Log in the VAKI Cloud will also allow access to current operational status and service information for your VAKI equipment in the VAKI Customer Care Program.
