Abstract

The invention discloses a live fish size detection device and a detection method. The live fish size detection device comprises a detection box, a frame and a controller, wherein the detection box is internally provided with a rotation shaft, and the rotation shaft is provided with a plurality of separators; the separators divide the detection box into a plurality of box lattices, one end of each box lattice is provided with an inlet door and a first switch, and the other end of each box lattice is provided with a baffle; a first motor is arranged outside the detection box, and the rotation shaft passes through the baffles to be connected with the first motor; each box lattice is internally provided with a fish attracting device, a first ultrasonic sensor, a second ultrasonic sensor and a binocular camera; the side wall of the detection box is provided with an outlet door and a second switch; and the controller is electrically connected with each first switch, the first motor, each fish attracting device, each first ultrasonic sensor, each second ultrasonic sensor, each binocular camera and the second switch respectively. Zero damages are caused to the fish body, human errors do not exist, and the measurement data are accurate.

Description

technical field [0001] The invention relates to the technical field of biological measurement equipment, in particular to a non-contact live fish size detection device and a detection method with zero damage to the fish body. Background technique [0002] In ichthyology research, it is often difficult to measure the body shape characteristic parameters of live fish. [0003] At present, the collection of fish size is generally measured manually by using a ruler, vernier caliper, tape measure, etc. The above-mentioned measurement method has the following disadvantages: manual measurement takes too long, and it needs to be measured out of water, so it often causes fish Damage, such as scales falling off, fin damage, etc., can cause death to live fish in severe cases; the size of fish requires a lot of data to be measured, and manual measurement and data recording often require the cooperation of two people to complete, wasting manpower and time. Low efficiency and large human...
