Abstract

The invention provides a fish growth data measurement device based on machine vision, and the device comprises a tray, an input apparatus, a weighing sensor, a controller and a camera. The weighing sensor is mounted on the tray, and the camera is arranged corresponding to the tray and the scale of the tray. The input device, the camera, and the weighing sensor are connected with the controller, and the controller sends a received shooting instruction to the camera, calculates the body length, the body width, the body circumference and the body area of a fish according to a fish body image anda scale image, sends the received weighing instruction to the weighing sensor, and receives the body weight of the fish. The camera captures the images of the fish body on the tray and the scale of the tray according to the shooting instruction, and obtains the fish body image and the scale image and then sends the images to the controller. The weighing sensor weighs the fish body according to theweighing instruction, obtains the weight of the fish body and sends the weight of the fish body to the controller. The device based on the machine vision measures the data of the fish body, is smallin time consumption, is small in fish body pressure, is small in damage risk, is small in impact on the feeding rate, and is accurate in measurement.

Description

technical field [0001] The invention relates to the field of measurement, and more specifically, to a machine vision-based fish growth data measurement device and measurement method. Background technique [0002] my country, as a big fishery development country, has a large scale of fish farming factories. The measurement of fish growth data is essential in the breeding process, which is related to the company's stocking of fish fry, feed feeding, disease control, harvesting and fishing, etc. [0003] The collection of traditional fish data mainly relies on a single instrument measurement, that is, the vernier caliper to measure the body length and width, and the weight measurer to measure the weight, etc. The measurement process requires multiple workers to work together. The process is cumbersome and the fish body is exposed to the air for a long time. Stress the fish body, increase the risk of damage or inhibit growth by reducing the fish's feeding rate. At present, ins...
