Intelligent Modular Camera Rig for Classroom Lecture Video Recording System with Automatic Lighting Adjustment

In today's scheme where COVID-19 is the biggest problem faced by the entire world in which it almost forced all schools to suspend and obliged the students to stay at home for their safety., a video recorded lecture is one of the best solutions and ways to help students in their studies. The researchers were intended to improve distance learning as well as its effectiveness to deliver a high-quality video by developing an intelligent system that can be beneficial for both users and viewers. The usage of Arduino Uno served as the brain that controls everything, which makes the system a one-person operation. Given the scenarios of having different values of lux in a room caused by multiple kinds of events, achieving the preferred luminance will be difficult. Nevertheless, our prototype will automatically produce and attain the necessary amount of lighting needed using the LDR sensor along with the code in Arduino. The movement of the platform where the camera is placed follows wherever the user goes in front of the rig as much as the face is recognized. It was then tested using different calibrations by testing and simulating different situations where there are different variables included, such as camera movement and light. The data will be examined using ANOVA test.
