Liigutustunnistus

Liigutustunnistus, meaning motion detection in Estonian, refers to the process of identifying and recognizing physical movement within a given environment. This technology is fundamental to a wide range of applications, from security systems to interactive displays and robotics. At its core, liigutustunnistus involves sensors that capture changes in the visual or physical landscape. These changes are then analyzed by algorithms to distinguish between actual movement and environmental noise or static elements.

Common methods for liigutustunnistus include passive infrared (PIR) sensors, which detect infrared radiation emitted by warm objects like humans and animals, and active systems like radar or lidar, which emit signals and measure their reflection. Video-based motion detection is also prevalent, using cameras to analyze sequences of images for differences. The sensitivity and accuracy of liigutustunnistus systems can vary significantly, impacting their suitability for different tasks. False positives, where movement is incorrectly detected, and false negatives, where actual movement is missed, are key challenges in the development of effective liigutustunnistus solutions. Its applications extend to home automation, where it can trigger lights or alarms, and in industrial settings for safety monitoring and process control.
