Digital soil mapping (DSM) relies on a broad pool of statistical methods, yet determining the optimal method for a given context remains challenging and contentious. Benchmarking studies on multiple datasets are needed to reveal strengths and limitations of commonly used methods. Existing DSM studies usually rely on a single dataset with restricted access, leading to incomplete and potentially misleading conclusions. To address these issues, we introduce an open-access dataset collection called Precision Liming Soil Datasets (LimeSoDa). LimeSoDa consists of 31 field- and farm-scale datasets from various countries. Each dataset has three target soil properties: (1) soil organic matter or soil organic carbon, (2) clay content and (3) pH, alongside a set of features. Features are dataset-specific and were obtained by optical spectroscopy, proximal- and remote soil sensing. All datasets were aligned to a tabular format and are ready-to-use for modeling. We demonstrated the use of LimeSoDa for benchmarking by comparing the predictive performance of four learning algorithms across all datasets. This comparison included multiple linear regression (MLR), support vector regression (SVR), categorical boosting (CatBoost) and random forest (RF). The results showed that although no single algorithm was universally superior, certain algorithms performed better in specific contexts. MLR and SVR performed better on high-dimensional spectral datasets, likely due to better compatibility with principal components. In contrast, CatBoost and RF exhibited considerably better performances when applied to datasets with a moderate number ( © 2025, CC BY-SA.

Indirect methods for visual SLAM are gaining popularity due to their robustness to environmental variations. ORB-SLAM2 [1] is a benchmark method in this domain, however, it consumes significant time for computing descriptors that never get reused unless a frame is selected as a keyframe. To overcome these problems, we present FastORB-SLAM which is light-weight and efficient as it tracks keypoints between adjacent frames without computing descriptors. To achieve this, a two stage descriptor-independent keypoint matching method is proposed based on sparse optical flow. In the first stage, we predict initial keypoint correspondences via a simple but effective motion model and then robustly establish the correspondences via pyramid-based sparse optical flow tracking. In the second stage, we leverage the constraints of the motion smoothness and epipolar geometry to refine the correspondences. In particular, our method computes descriptors only for keyframes. We test FastORB-SLAM on TUM and ICL-NUIM RGB-D datasets and compare its accuracy and efficiency to nine existing RGB-D SLAM methods. Qualitative and quantitative results show that our method achieves state-of-the-art accuracy and is about twice as fast as the ORB-SLAM2. Copyright © 2020, The Authors. All rights reserved.

The rapid development of autonomous driving in recent years presents lots of challenges for scene understanding. As an essential step towards scene understanding, semantic segmentation thus received lots of attention in past few years. Although deep learning based state-of-the-arts have achieved great success in improving the segmentation accuracy, most of them suffer from an inefficiency problem and can hardly applied to practical applications. In this paper, we systematically analyze the computation cost of Convolutional Neural Network(CNN) and found that the inefficiency of CNN is mainly caused by its wide structure rather than the deep structure. In addition, the success of pruning based model compression methods proved that there are many redundant channels in CNN. Thus, we designed a very narrow while deep backbone network to improve the efficiency of semantic segmentation. By casting our network to FCN32 segmentation architecture, the basic structure of most segmentation methods, we achieved 60.6% mIoU on Cityscape val dataset with 54 frame per seconds(FPS) on 1024 × 2048 inputs, which already outperforms one of the earliest real time deep learning based segmentation methods: ENet.

Recently a large variety of robots are available on the global market for a reasonable price. Often it turns out that even though a robot has a high-quality hardware and architecture, an original software of the robot may have a number of drawbacks or lacks some important features, which are required for a particular application of the robot. In such cases a user may decide to implement new libraries and functionalities using a provided by a manufacturer application programming interfaces as in most cases code of a commercial robot system is not an open-source. A number of our ongoing research projects concentrate on applications of various robots in urban search and rescue operations, and in most of these projects utilize Russian crawler robot Servosila Engineer. This paper describes the development of a new ROS-based control software and graphical user interface for Servosila Engineer robot. © The Authors, published by EDP Sciences.

The deep-learning-based method is a costly method that requires the addition of a lot of learning data and hardware. This paper proposes a 3D vehicle detection method using only 3D lidar in autonomous vehicles. The proposed method generates density image and height image using point clouds. Candidates of the vehicle are detected from the complex image, and images for extracting features are generated from each candidate. In addition, we use the SVM (Support Vector Machine) instead of deep-learning, a low-cost learning method, to classify HOG (Histogram of Oriented Gradient) feature vectors. The proposed method can reduce the amount of computation as well as the execution time. The vehicle can be detected and the distance to the vehicle can be measured. Experimental results show the performance of the proposed method. © ICROS 2018.

With the development of science and technology, virtual reality technology has been applied to various fields. Virtual reality technology is proposed into rehabilitation medical treatment, which can avoid dull rehabilitation training, improve the initiative of patients' rehabilitation and improve the overall effect of rehabilitation training. In order to help patients with hand grab function training, we proposed a virtual reality-based upper limb rehabilitation hand training system. In this paper, we can obtain the bending angle data of fingers and force feedback through the upper limb rehabilitation hand robot with CyberGlove. We established the high precise 3D model, set up the mapping relationship between CyberGlove and the virtual hand to realize the human-computer interaction. Based on the previous work, a VR-based upper limb rehabilitation hand robotic training system is proposed and has collision detection and force feedback, which makes users feel more realistic when interacting with objects in the virtual environment. The relevant verification experiment confirmed that virtual hand and upper limb rehabilitation robot interact well, which increases the interest of training. © 2018 IEEE.

In order to help stroke patients to go on rehabilitation training, a new type of exoskeleton upper limb rehabilitation robot based on biomechanics has been designed in this paper, and speech control has been implemented. The speech control is suitable for patients who can speak. Doctors or family members can also assist patients in training. The system can help patients with hemiplegia to recover the upper limbs and fingers movement function, at the same time, it has the characteristics of small size, more portable and convenient operation. It can also effectively solve the shortage of traditional doctors and patients' one to one rehabilitation training. It is convenient for patients to use in the family. Anybody can help patients with rehabilitation training and has a broad application prospect in the field of rehabilitation. Finally, the speech control system was tested and the master-slave control experiment was implemented. In order to better perform speech recognition and further reduce the noise in the environment, the original speech signals have been de-noised with wavelet transform . The experimental results showed that the success rate of post-noise speech control system rehabilitation training is higher, and the average correct recognition rate of speech control is 94%, thus the feasibility of the speech control system is verified. © 2018 IEEE.

Genetic algorithms (GA) and ant colony algorithm (ACO) are computational models that simulate the process of biological evolution and are widely applied to problems related to path planning. This paper proposes a path planning algorithm which combines the genetic algorithm and the ant colony algorithm. The hybrid algorithm overcomes the problem of genetic algorithm's poor ability in local search, and overcomes the slow convergence speed, local optimal solution of ant colony algorithm's in the process of convergence. The effectiveness and rapidity of the proposed hybrid algorithm is verified by simulation and experiment. The overall performance is better than the genetic algorithm and the ant colony algorithm. Finally, we carried out the experiments to verify the effectiveness of the proposed hybrid algorithm which could avoid collision and reach the target safely, and the proposed hybrid algorithm was compared with ACO and GA respectively. The experimental results showed that the proposed hybrid algorithm overcame the defects of ACO and GA, verified the effectiveness and rapidity of the proposed hybrid algorithm. © 2018 IEEE.
