One of the unique features in the structured and well-organized agriculture field is the arrangement of the plants and crops in such long rows that leaves a small pathway in between them. This pathway is really important to facilitate the movement of the farmers or tractors in providing a maximum plant scouting and monitoring throughout the entire farm. Therefore, in this work, an embedded and automated...
In autonomous quadrocopter navigation, wind disturbances commonly pose a problem for the vehicle to navigate precisely on the planned path. The vehicle easily deviates off from the path and obviously affects the navigation accuracy. Trajectory correction is one possible solution proposed by few researchers to avert the problem. The approaches are proven to increase the efficiency for the vehicle to...
Create a map is an initial task for a robot to maneuver or navigated automatically in a proposed area. It is a difficult task for a robot creates a map and performs the desired task concurrently especially on an aerial application. Aerial application needs a simple and light computational method in order to process the applied algorithm. This paper presents a distinctive technique of single line scanning...
Precise tree diameter estimation for a lightweight and intelligent vehicle such as unmanned aerial vehicle (UAV) in a commercial farm is still an unresolved problem. A lot of UAVs and the ground vehicles (UGV) are navigated across the farm by relying on the aided of the vision sensor as well as laser scanner. All of these methods require an extremely massive image computation, bulky package dimension...
Deviation from a planned path due to dynamic wind disturbances clearly will defect the quadrocopter navigation accuracy thus result to poor execution of a task. Few researchers proposed correction algorithms to be integrated in the autonomous quadrocopter system for the problem arises. However, the algorithms are not applicable to enable quadrocopter to navigate precisely on a planned trajectory around...
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...
This paper presents a new approach in determining the diameter of cylindrical object based on the available two triangles formation technique. The proposed hardware-software system is useful to be implemented on an unmanned aerial vehicle platform in the agriculture field for row detection and navigation techniques based on simultaneous localization and mapping technique as it offers a lightweight...
One of the important aspects in building an autonomous vehicle with the cognitive capability in agriculture field is the potentiality of it to recognize the trees or significant landmarks and map it for future navigation process. Therefore, it is crucial for a machine to detect the trees and keep tracking between them in order to perform the plantation activities autonomously. One of the challenges...
In agriculture field, one of the important task for an automated machine is to detect the trees and keep tracking between them in order to perform the plantation activities. One of the challenges face by this implementation is when the trees are planted at a wider distance to one another. Therefore, individual tree detection is very crucial in facilitating the navigation of the automated machine between...
Surface mappings are widely implemented for use in application of an autonomous robot especially in Unmanned Aerial Vehicle application such as forest monitoring for plantation and etc. A lot of surface mappings were implemented on large surface area with high altitude which needs a capable and special sensor to map such as satellite that produces geographical data for map. The paper proposed a low-altitude...
Autonomous quadrocopter recently has shown a significant usages and potentials to be used widely in the commercial market. This caused the aircraft to become a well-liked subject among the researchers and research organizations. With good controllability and stability on its motions will make the usability of the quadrocopter to perform a task reliably. For this to happen, clean signals from accelerometer...
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...
This paper presents a review of previous work in the field of the unmanned autonomic vehicles in the agricultural field, particularly in the real-time inter-row tracking and localization techniques. A new method in row detection techniques based on simultaneous localization and mapping is proposed. The inter-row tracking technique differs from other available approaches done in terms of detection...
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...
