Circadian rhythm is a biological process that repeats according to environmental conditions and occurs due to the change of light and temperature. Plants are triggered by biological clocks to help adapt to dark and light changing times in accordance with the presence of light and environmental temperature conditions. The objective of this study was to develop an automatic plant monitoring system to measure the motion rhythmic in plant based on leaf motion. The proposed system allows continuous, high-resolution time-lapse imaging, independent of the presence of visible light, and based on the open-source platform. The system utilized an infrared (IR) camera positioned above and side of the plant as top view projection and side view projection respectively. As the motion tracking, the Optical Flow method was adopted, implementing the Lucas-Kanade technique combined with Shi-Tomasi corner detection. Optical flow is one of the motion detection methods to analyze the motion between two consecutive images by differentiating the constraint. Average of the displacement distance (V) was used as a parameter for representing the motion. As the result, the proposed system could be used to monitor the plant motion resembles the diurnal circadian rhythm. Further investigation of the rhythmic motion and its relation to environmental treatment will be in the future works |
