Abstract

We propose a method to measure the number of specific species of class using CAFFE model and a method to measure length and width of object using stereo vision. To obtain the width of an object, the location coordinates of objects appearing on the left and right sensor is compared and the distance from the sensor to the object is obtained. Then the length of the object in the image by using the distance and the approximate value of the actual length of the object is calculated.

CAFFE 모델을 이용하여 클래스의 특정 종의 수량 측정하는 방법과 스테레오 비전을 이용하여 물체의 길이와 너비를 측정하는 방법을 제안한다. 물체의 너비를 구하는 방법은 좌측 센서와 우측 센서의 대상의 좌표 값을 비교하여 센서부터 물체까지의 거리를 계산한다. 그 후 거리와 영상 속의 대상의 길이를 구해 물체의 실제 길이의 근사 값을 계산한다.
