Abstract

In recent years, China has accelerated the development of oiltea camellia industry and promoted the expansion of oiltea camellia cultivation nationwide, necessitating a refined agricultural climate zoning for oiltea camellia cultivation across the country. Considering soil factors is crucial for enhancing the precision of agricultural climate zoning for oiltea camellia. Therefore, based on the selection of potential climate factors affecting oiltea camellia cultivation distribution, as well as land conditions such as slope and soil thickness, dominant climate factors are analyzed using maximum entropy (MaxEnt) model and ArcGIS technology. It provides a refined climate zoning of oiltea camellia cultivation in China based on the joint effect of climate and land, identifying the potential for expansion and offering a scientific basis for the planning and implementation of oiltea camellia expansion. Results indicate the dominant climate factors affecting oiltea camellia cultivation distribution in China are the average temperature in January, accumulated temperature above or equal to 10 ℃, consecutive days with minimum temperature equal to or below -10 ℃, and annual cumulative precipitation. Taking into account the impact of slope and soil thickness on climatic suitability analysis, the climate zoning for oiltea camellia is divided into four suitability levels: The most suitable, more suitable, suitable region, and unsuitable region. The area for the most suitable region is 3.003×107 hm2, more suitable region is 2.858×107 hm2, and suitable region is 1.458×107 hm2.The precision of regional climate zoning for oiltea camellia cultivation is enhanced, reducing the suitable planting area for oiltea camellia by two-thirds compared to those not considering land factors. Suitable cultivation areas for oiltea camellia in China are in the region south of Yangtze River, especially from Sichuan Basins to the Qinling Mountains to the south of Huai River, and the east of Yungui Plateau to the coastal areas. Compared to the current planting area and range, oiltea camellia in China has significant potential for expansion. The potential planting boundaries, considering the joint effect of climate and land, tend to be further north. It suggests significant potential for expansion in the distribution of oiltea camellia in China. Therefore, when planning the layout of oiltea camellia cultivation, in addition to considering major planting areas such as Hunan, Jiangxi, Guangxi and Hubei, provinces with significant expansion potential such as Yunnan, Sichuan, Guangdong and Chongqing should also be taken into account, and their planting areas should be appropriately increased.

14. On Deep Recurrent Reinforcement Learning for Active Visual Tracking of Space Noncooperative Objects

Abstract

Active tracking of space noncooperative object that merely relies on vision camera is greatly significant for autonomous rendezvous and debris removal. Considering its Partial Observable Markov Decision Process (POMDP) property, this paper proposes a novel tracker based on deep recurrent reinforcement learning, named as RAMAVT which drives the chasing spacecraft to follow arbitrary space noncooperative object with high-frequency and near-optimal velocity control commands. To further improve the active tracking performance, we introduce Multi-Head Attention (MHA) module and Squeeze-and-Excitation (SE) layer into RAMAVT, which remarkably improve the representative ability of neural network with almost no extra computational cost. Extensive experiments and ablation study implemented on SNCOAT benchmark show the effectiveness and robustness of our method compared with other state-of-the-art algorithm. The source codes are available on https://github.com/Dongzhou-1996/RAMAVT.

20. Space Non-cooperative Object Active Tracking with Deep Reinforcement Learning

Abstract

Active visual tracking of space non-cooperative object is significant for future intelligent spacecraft to realise space debris removal, asteroid exploration, autonomous rendezvous and docking. However, existing works often consider this task into different subproblems (e.g. image preprocessing, feature extraction and matching, position and pose estimation, control law design) and optimize each module alone, which are trivial and sub-optimal. To this end, we propose an end-to-end active visual tracking method based on DQN algorithm, named as DRLAVT. It can guide the chasing spacecraft approach to arbitrary space non-cooperative target merely relied on color or RGBD images, which significantly outperforms position-based visual servoing baseline algorithm that adopts state-of-the-art 2D monocular tracker, SiamRPN. Extensive experiments implemented with diverse network architectures, different perturbations and multiple targets demonstrate the advancement and robustness of DRLAVT. In addition, We further prove our method indeed learnt the motion patterns of target with deep reinforcement learning through hundreds of trial-and-errors.

22. A General Framework for Lifelong Localization and Mapping in Changing Environment

Abstract

The environment of most real-world scenarios such as malls and supermarkets changes at all times. A pre-built map that does not account for these changes becomes out-of-date easily. Therefore, it is necessary to have an up-to-date model of the environment to facilitate long-term operation of a robot. To this end, this paper presents a general lifelong simultaneous localization and mapping (SLAM) framework. Our framework uses a multiple session map representation, and exploits an efficient map updating strategy that includes map building, pose graph refinement and sparsification. To mitigate the unbounded increase of memory usage, we propose a map-trimming method based on the Chow-Liu maximum-mutual-information spanning tree. The proposed SLAM framework has been comprehensively validated by over a month of robot deployment in real supermarket environment. Furthermore, we release the dataset collected from the indoor and outdoor changing environment with the hope to accelerate lifelong SLAM research in the community. Our dataset is available at https://github.com/sanduan168/lifelong-SLAM-dataset.
