Automatic bait casting method based on sound wave location and image collection

Abstract

The present invention relates to an automatic bait casting method based on sound wave location and image collection, belonging to the detection method technology field. The method comprises the following steps: after performing bait casting into a net cage, allowing baits to be gradually submerged in water, and allowing shoal of fish to start feeding in the submerging process; employing a Doppler particle sensor, performing location of residual feeds; employing the Doppler particle sensor, performing image collection of the residual feeds located by the Doppler particle sensor; employing the images collected by the Doppler particle sensor for analysis to distinguish bait particles and other substances; determining whether the residual feed amount submerged at the bottom of the net cage reaches a substantial level or not; allowing the Doppler particle sensor to perform real-time detection of the position and the density of the shoal of fish; and when the residual feed amount is lower than a setting substantial level and the shoal of fish is located at a residual feed area and is large in density, allowing a controller to control a bait caster to cast the baits; and when the residual feed amount is higher than the setting substantial level and the shoal of fish is not located at the residual feed area, or the shoal of fish is low in density, stopping putting of the baits.

Description

technical field [0001] The invention relates to a fully automatic bait casting method based on acoustic wave positioning and image acquisition, and belongs to the technical field of detection methods. Background technique [0002] Compared with the existing bait feeding machine method, the feeding amount is preset first, and the feeding is stopped when the feeding amount is reached. Often, the dynamic change of fish feeding in the real situation is ignored and the quantitative inaccurate feeding is carried out, which is easy to cause overdose Feed is wasted due to feeding. At the same time, the accumulation of feed in the water pollutes the water quality and the water environment around the cages, which affects the survival and growth of fish schools. It is also possible that the amount of feeding is insufficient, which cannot meet the feeding needs of fish schools and cannot realize the growth potential of fish schools. , leading to slow fish growth.
