이하에서는 본 발명을 명확하게 설명하기 위해서 본 발명과 밀접한 관계가 없는 부분은 상세한 설명을 생략하였으며, 발명의 설명 전체를 통하여 동일 또는 유사한 구성요소에 대해서는 동일한 참조 부호를 붙이고, 반복적인 설명을 생략한다.Hereinafter, in order to clearly describe the present invention, detailed descriptions of parts that are not closely related to the present invention are omitted, and the same or similar elements are denoted by the same reference numerals throughout the description of the present invention, and repetitive descriptions are omitted. .
먼저, 본 발명의 일실시예에 따른 다분광센서 탑재 드론을 활용한 식생상태분석 및 환경오염 모니터링방법은, 도 1 및 도 2에 나타낸 바와 같이, 분광데이터수집단계(S10)와, 비교분석단계(S20)와, 식생환경평가단계(S30)를 포함하여 이루어진다.First, the vegetation condition analysis and environmental pollution monitoring method using a drone equipped with a multispectral sensor according to an embodiment of the present invention, as shown in Figs. 1 and 2, a spectral data collection step (S10) and a comparative analysis step It comprises (S20) and the vegetation environment evaluation step (S30).
상기 분광데이터수집단계(S10)에서는 다분광센서(20)가 탑재된 드론(10)을 이용하여 주기적으로 분광데이터를 수집한다.In the spectral data collection step (S10), spectral data is periodically collected using a
상기 드론(10)에 탑재되는 다분광센서(20)는 가시광선 및 극적외선 대역의 10개 이내 파장의 분광을 측정 수집하도록 구성하는 것이 바람직하다.It is preferable that the
상기 드론(10)에 탑재되는 다분광센서(20)는 5개 이내의 분광을 측정 수집하도록 구성하는 것도 가능하다.The
예를 들면, 상기 드론(10)에 탑재되는 다분광센서(20)는 주로 색상정보가 필요한 경우에는 400~1,000nm 파장대의 분광데이터를 수집하도록 구성하는 것도 가능하다.For example, the
또, 상기 드론(10)에 탑재되는 다분광센서(20)는 주로 수분정보와 지질특성, 재질식별에 필요한 분광데이터가 필요한 경우에는 1,000~2,500nm 파장대의 분광데이터를 수집하도록 구성하는 것도 가능하다.In addition, the
나아가, 상기 드론(10)에 탑재되는 다분광센서(20)는 대상물의 온도정보와 재질식별, 가스탐지 등에 유용한 분광데이터가 필요한 경우에는 8~12㎛ 파장대의 분광데이터를 수집하도록 구성하는 것도 가능하다.Furthermore, the
일반적으로, 전자기 스펙트럼에 있어서 물체마다 고유한 특성을 나타내는 파장대가 있으므로, 이를 이용하면 대상물의 상태를 평가하는 것이 가능하다.In general, in the electromagnetic spectrum, each object has a wavelength band that exhibits a unique characteristic, and by using this, it is possible to evaluate the state of the object.
예를 들면, 대기와 수중(50m)의 경우에는 블루(blue) 파장대인 450~515nm 파장대를 이용하고, 식물과 수중구조물(30m)의 경우에는 그린(green) 파장대인 520~590nm 파장대를 이용하고, 인공구조물과 수중(9m)의 경우에는 레드(red) 파장대인 630~680nm 파장대를 이용하고, 농작물의 경우에는 근적외선 파장대인 750~900nm 파장대를 이용하고, 농작물이나 토양의 수분함유율의 경우에는 중적외선 파장대인 1,550~1,750nm 파장대를 이용하고, 토양, 수분, 지형, 화재 등의 경우에는 원적외선 파장대인 2,080~2,350nm 파장대를 이용하고, 복사에너지와 유수의 온도, 화재, 야간탐사의 경우에는 열적외선 파장대인 10,400~12,500nm 파장대를 이용하는 것이 바람직하다.For example, in the case of air and underwater (50m), the blue wavelength band of 450-515nm is used, and in the case of plants and underwater structures (30m), the green wavelength band of 520-590nm is used. , In the case of artificial structures and underwater (9m), the red wavelength band of 630~680nm is used, in the case of crops, the near-infrared wavelength band of 750~900nm is used, and in the case of the moisture content of crops or soil, medium The infrared wavelength band of 1,550~1,750nm is used, in the case of soil, moisture, topography, fire, etc., the far-infrared wavelength band of 2,080~2,350nm is used. It is preferable to use the infrared wavelength band of 10,400 to 12,500 nm.
상기 드론(10)에 탑재되는 다분광센서(20)는 400~12,500nm 파장대 중에서 3~5개 정도(또는 5~10개 정도)를 선택하여 분광데이터를 수집하는 것이 가능하도록 구성하는 것도 가능하다.The
상기에서 많은 파장대 및 넓은 파장대의 분광데이터를 수집하도록 구성하게 되면, 다분광센서(20)의 원가가 상승하므로, 식생환경의 모니터링의 목적을 위해 필요로 하는 분광데이터의 수집에 필수적인 파장대로 한정하여 다분광센서(20)를 구성하는 것이 바람직하다.If it is configured to collect spectral data in a large number of wavelength bands and in a wide wavelength band, the cost of the
상기 비교분석단계(S20)에서는 상기 분광데이터수집단계(S10)에서 수집된 분광데이터를 이전 데이터와 비교 분석하는 과정을 수행한다.In the comparative analysis step S20, a process of comparing and analyzing the spectral data collected in the spectral data collection step S10 with previous data is performed.
상기 비교분석단계(S20)에서의 분광데이터의 비교 분석은 이전 주기에서 수집된 분광데이터와 현재 주기에서 수집된 분광데이터를 동일 지역에서 파장의 분포를 비교하는 것에 의하여 색상의 변화, 수분량의 변화, 온도의 변화 등을 분석하도록 이루어진다.The comparative analysis of the spectral data in the comparative analysis step (S20) is performed by comparing the spectral data collected in the previous period and the spectral data collected in the current period by comparing the distribution of wavelengths in the same area, thereby changing the color, changing the moisture content It is made to analyze changes in temperature and the like.
상기 식생환경평가단계(S20)에서는 상기 비교분석단계(S20)에서 분석된 분광데이터의 색상분포와 파장분포를 평가하여 식생환경의 상태를 진단하는 과정을 수행한다.In the vegetation environment evaluation step (S20), a process of diagnosing the state of the vegetation environment is performed by evaluating the color distribution and wavelength distribution of the spectral data analyzed in the comparative analysis step (S20).
상기와 같은 과정을 거쳐 분광데이터를 분석하고 평가하면, 식물의 상태, 녹조 및 적조의 발생과 확산의 정도 등을 모니터링하는 것이 가능하다.By analyzing and evaluating the spectral data through the above process, it is possible to monitor the condition of plants, the degree of occurrence and spread of green algae and red algae.
예를 들면, 분광데이터를 분석하여 나뭇잎의 수분량을 평가하는 것에 의하여 소나무재선충병에 의해 나무가 고사된 지역의 정도, 가뭄의 정도 등을 모니터링하는 것이 가능하다.For example, by analyzing spectral data and evaluating the moisture content of the leaves, it is possible to monitor the degree of the area where the tree died by the nematode nematode, the degree of drought, and the like.
예를 들면, 식물의 성장 상태를 평가하고자 하는 경우에는 다음의 수학식 1에 나타내는 정규 식생지수(NDVI; Normalized Difference Vegeration Index)를 활용하는 것이 가능하다. 정규 식생지수(NDVI)는 가시광선 파장대와 근적외선 파장대의 정보를 수식화하여 처리한 지수이다.For example, in the case of evaluating the growth state of a plant, it is possible to use the Normalized Difference Vegeration Index (NDVI) shown in Equation 1 below. The normal vegetation index (NDVI) is an index processed by formulating information on the visible and near-infrared wavelength bands.
상기 수학식 1에 있어서, NIR은 근적외선(Near Infrared) 파장대의 반사도를 나타내고, Red는 적색(Red) 파장대의 반사도를 나타낸다.In Equation 1, NIR represents the reflectivity in the near infrared wavelength band, and Red represents the reflectivity in the red wavelength band.
