“…With the research development, the technology will be more applied in farmland environmental sensing. Kragh et al [34] proposed a multimodal obstacle detection method based on the fusion of conditional random field, laser radar and camera (Figure 8c). Camera and laser radar are combined in a probabilistic manner while the spatial temporal, and multimodal links between corresponding 2D and 3D regions as well as the data pairs collected in various agricultural environments by mobile ground vehicles are used.…”

Field environmental sensing can acquire real-time environmental information, which will be applied to field operation, through the fusion of multiple sensors. Multi-sensor fusion refers to the fusion of information obtained from multiple sensors using more advanced data processing methods. The main objective of applying this technology in field environment perception is to acquire real-time environmental information, making agricultural mechanical devices operate better in complex farmland environment with stronger sensing ability and operational accuracy. In this paper, the characteristics of sensors are studied to clarify the advantages and existing problems of each type of sensors and point out that multiple sensors can be introduced to compensate for the information loss. Secondly, the mainstream information fusion types at present are outlined. The characteristics, advantages and disadvantages of different fusion methods are analyzed. The important studies and applications related to multi-sensor information fusion technology published at home and abroad are listed. Eventually, the existing problems in the field environment sensing at present are summarized and the prospect for future of sensors precise sensing, multi-dimensional fusion strategies, discrepancies in sensor fusion and agricultural information processing are proposed in hope of providing reference for the deeper development of smart agriculture.

“…The metal bond surrounding abrasives is removed by amassed erosion, and thus the abrasives can stick from the grinding wheel surface. 10,11 On the other hand, the abrasives’ temperature should be controlled to be below decomposing point (740 °C–840 °C). That is because abrasives are easily subjected to graphitization above decomposing point and then would be damaged by intense heat.…”

Truing and dressing of superabrasive grinding wheels remain as one of the most important issues in hard-to-cut materials' precise machining field. Recently, electrical discharge dressing process with less pollution, aimed to protect environment, has become an urgent studying subject in the world. In this study, various discharge mediums including kerosene-based oil, compressed air, misted deionized water, and misted emulsion were applied in electrical discharge dressing bronze-bonded diamond grinding wheels. Misted deionized water and misted emulsion are liquid-gas mixture. The dressing quality of wheels with various mediums was analyzed according to wheel topographies. The dressing efficiency of various discharge mediums was evaluated by the dressing depth divided by the dressing time. In addition, the performance of electrical discharge dressed wheel was investigated in practical grinding. Misted deionized water and misted emulsion electrical discharge dressing show advantages over the compressed air electrical discharge dressing in better dressing quality and higher dressing efficiency. Compared to kerosene-based oil electrical discharge dressing, misted deionized water and misted emulsion electrical discharge dressing have better dressing quality and lower dressing efficiency.
