AI Fish Size Estimation Camera
The patented AI Fish Size Estimation Camera is a product that records images of fish with a stereocamera, detects the fish body using deep learning image recognition technology, and measures the size based on the positional information from the two lenses of the stereo camera.
Underwater camera for fish size recognition
The AI Fish Size Estimation Camera combines deep learning and stereo camera surveying technology to estimate fish size without physical contact. This device uses an underwater stereo camera with two cameras positioned side by side to capture three-dimensional images of swimming fish. Fish that appear sideways in the images are detected using deep learning object detection technology. The size of the detected fish is calculated using the position information of the fish and the principles of the stereo camera.
At the time of patent acquisition, the measurements included ‘body length’ from the tip of the upper jaw to the base of the tail fin and ‘body height’ from the base of the dorsal fin to the base of the pelvic fin. Currently, it is also possible to measure fork length, total length, and weight.
Concept
The AI Fish Size Estimation Camera is a system that captures fish using a stereo camera, detects fish bodies through deep learning image recognition technology, and calculates the length and height of the fish based on their position information.
This system allows for the measurement of fish size and weight without removing them from the pond. Data on fish body size and weight, including ‘average’, ‘maximum’, ‘minimum’, and ‘standard deviation’, can be viewed in a list format on a computer or smartphone. In addition to listing the data, the system enables the accumulation of video data and the visualization of measurements over time through graphs, making it possible to monitor growth processes in real-time and analyze accumulated data.
Furthermore, since learning models are created for each fish species, the system can measure various fish species without being limited to specific ones.
Analyze growth
The reports not only lists data values, but also stores video data and easily generates graphs for data analysis.
