Provided are a soil-water characteristic curve (SWCC)-hyperspectral cam test method and an apparatus for measuring reflectance by volumetric water content. According to an embodiment, the SWCC-hyperspectral cam test method for measuring reflectance by volumetric water content comprises the following steps of: acquiring volumetric water content with respect to a ground sample by performing an SWCC test; and measuring reflectance by volumetric water content of the ground sample by performing a hyperspectral camera test using the volumetric water content acquired with a result of the SWCC test. 체적함수비별 반사율 측정을 위한 함수특성곡선-초분광 캠 테스트 방법 및 장치가 제시된다. 일 실시예에 따른 체적함수비별 반사율 측정을 위한 함수특성곡선-초분광 캠 테스트 방법은, 함수특성곡선(Soil-Water Characteristic Curve, SWCC) 시험을 수행하여 지반 시료에 대한 체적함수비를 획득하는 단계; 및 상기 함수특성곡선 시험 결과로 획득한 상기 체적함수비를 이용하여 초분광 카메라 시험을 수행하여 상기 지반 시료의 체적함수비별 반사율을 측정하는 단계를 포함하여 이루어질 수 있다.
