Estimation of 4-DoF manipulator optimal configuration for autonomous camera calibration of a mobile robot using on-board templates
Ch. 9438925.
Camera calibration is one of the important tasks in the field of robotics and computer vision. It enables to increase the accuracy of metric measurements in photogrammetry applications and provides higher performance in computer vision algorithms such as stereo matching and motion estimation. It is known that regardless of the calibration method used variation of given estimated camera parameters their is inevitable due to multiple reasons: varying weather conditions, temperature fluctuations or severe operation mode of a robotic system. In order to alleviate the aforementioned issues recalibration is required. In this work we employed 4-DoF manipulator Servosila Engineer mobile robotic system equipped with an on-board camera. In order to automate the process of calibration an algorithm is developed which enables to estimate optimal manipulator joint configurations. Forward kinematics is solved on a discretized set of joint angles, subsequently estimating possible camera positions for its further calibration. Experiments on real robot demonstrate the possibility of usage of the developed algorithm to find optimal joint configurations for automatic camera calibration.

Manual assessment of soybean yield components, such as pod number, is laborious, time-consuming, and subjective. Existing computer-vision approaches based on object detection or instance segmentation perform poorly on close-range RGB imagery of soybean canopies due to severe occlusions, ambiguous plant boundaries, and the high cost of bounding-box annotation. To address these challenges, we propose a ...

Improving image quality is becoming an increasingly popular task, especially when working with mobile devices. One common approach to image enhancement is the use of convolutional neural networks. However, to achieve good results, such networks must be large enough, otherwise there is a risk of unwanted artifacts. In addition, large convolutional neural networks require significant ...

In this work, we propose a ratio-dependent intraguild predation model that incorporates fear and gestation delay. Further, the cost of the intraguild predator's fear is thought to decrease the size of the intraguild prey. The interaction between prey and predator takes place in the form ratio-dependence type. This type of functional response offers a valuable ...
