Abstract
An underwater detection system is provided that can effectively use a discrimination result. A fish detector of the system is configured to implement a discrimination function including a fish species discrimination function; however, a fish detector and a sonar of the system do not comprise such a discriminator including a fish species discriminator. The fish detector transmits various discrimination results such as fish species discrimination, etc., through an onboard LAN to the fish detector or the sonar. The fish detector and the sonar superimpose various received discrimination results on the detection result of the device itself and display them on a display.
Claims14
An underwater detection device that detects a school of fish based on an echo received from an underwater detector by transmitting and receiving an ultrasonic wave, and displays an echo image of the school of fish on a screen, comprising:
- an acquisition module for acquiring fish species information in connection with position information indicating the position where an external device distinguished the fish species information;
- a determiner for determining based on the position information whether the school of fish displayed as the echo image on the screen and the school of fish from the fish species information acquired by the acquisition module are the same school of fish or not;
- and
- a display combiner for displaying the acquired fish species information superimposed on the echo image of the school of fish on the screen when the determiner determines they are the same school of fish.
An underwater information display system, comprising:
- a fish detector for transmitting and receiving an ultrasonic wave directly below the device itself, detecting fish species information from an acquired echo signal, and transmitting the detected fish species information in connection with position information indicating the position of the acquired fish species information;
- and
- an underwater detection device having an acquisition module that acquires the fish species information transmitted from the fish detector and the position information, a display that detects a school of fish based on an echo acquired by underwater detection by transmitting and receiving the ultrasonic wave and displays an echo image of the school of fish, a determiner that determines based on the position information whether the school of fish displayed as the echo image on the display and the school of fish for which fish species information was acquired by the acquisition module are the same school of fish or not, and a display combiner that displays the acquired fish species information by superimposing on the echo image of the school of fish on the screen when determined to be the same school of fish by the determiner.
An underwater information display method according to which an underwater detection device detects a school of fish based on an echo acquired by underwater detection by transmitting and receiving an ultrasonic wave and displays an echo image of a school of fish on a screen, comprising the steps of:
- at a fish detector:
- transmitting and receiving an ultrasonic wave directly below the device itself, detecting fish species information from an acquired echo signal, and transmitting the detected fish species information in connection with a position information indicating the position where the fish species information was acquired, and
- at the underwater detection device:
- acquiring the fish species information transmitted from the fish detector and the position information;
- detecting the school of fish based on an echo acquired by underwater detection by transmitting and receiving the ultrasonic wave, and displaying the echo image of the school of fish;
- determining based on the position information whether the school of fish displayed as the echo image on the display and the school of fish for which the fish species information was acquired are the same school of fish or not, and
- displaying the acquired fish species information superimposed on the echo image of the school of fish on the screen when the school of fish displayed as the echo image is determined to be the same school of fish for which the fish species information was acquired by the determiner.
