Fish species and body length measurement method using the image

摘要

The present invention relates to a type of fish and a method for measuring the length of a fish using an image capable of measuring the type and length of the fish obtained through a fishing activity such as fishing, wherein the user terminal is located in a short distance from the fish and the fish to obtain an image in which the auxiliary aid engraved with a marker is captured; recognizing a specific marker in the acquired image to distinguish the auxiliary; and image processing the obtained image to extract the outline image of the fish; determining the type of fish by comparing the outline image with pre-stored shape information for each fish, and measuring the length of the auxiliary object by comparing the auxiliary material recognized through the marker with the pre-stored auxiliary size information for each marker; Scanning the outline shape from the image-processed image, calculating the maximum value among the distances from the first point to the second point corresponding to the length of the fish in the outline, and the ratio of the actual length of the auxiliary object to the length on the image Through the step of determining the length of the fish by multiplying the coefficient and the variable that is the distance between the first point and the second point of the fish, image the fish caught by fishing using a mobile communication terminal such as a universal smartphone It is possible to easily measure the body length such as the type and length of the fish from the captured image.
