Feature detection is an important task for an autonomous vehicle in getting reference or guide in a agriculture field. Recently, a lot of sensors were implemented for feature detection of a field such as sonar sensor, laser range finder, infrared sensor which it is used as height estimation, size area measurement and path tracking that act as reference for desired measurement in creating a virtual...
The aim of this paper is to evaluate real-time accurateness of low-altitude height measurement using a single sonar sensor via Kalman filter algorithm in embedded controller. The function of the one dimension embedded Kalman filter of sonar sensor is to reduce and resolve the error of low altitude height measurement that produced from the sensor for mapping application. Series data of varied height...
Analytical processes is performed for calculating point distance using ultrasonic sensors, with the intention to resolve a low-altitude two-dimensional surface mapping using UAV. An experimental structure model was constructed to allow for dynamic one-dimensional movement of the sensor system in a horizontal plane. Sample experimental surfaces are chosen to be scanned by the sensor system and recreation...
