其他语种文摘 Recently,significant developments of visual sensing have been observed in imaging technology and data processing, thereby providing great opportunities to enhance our ability to perceive and recognize our real world. Therefore,investigations on visual sensing possess important theoretical value and are required for application needs. Surveying the progress to understand the trend in the field of visual sensing and to clarify the future research direction is beneficial. The reviews are generated mainly based on analyzing peer-reviewed academic publications and related reports. A general description on the states of the art and trends about the visual sensing is provided,mainly including laser scanning,high dynamic range (HDR) imaging,polarization imaging,and ocean acoustic tomography. Specifically,for each of these imaging fields,parts discussed include new hardware,processing technology,and application scenarios. Processing of 3D point cloud data has become more effective along with the great progresses in deep learning and the advancement of hardware devices. Mean-while,applications of 3D point cloud data are increasingly popular for diverse purposes. Over past several years,many domestic institutions and teams focused on developing algorithms for 3D point cloud data processing,such as in feature extraction,semantic labeling and segmentation,and object detection. In particular,several teams have conducted a number of substantive work in the production and sharing of standard data sets,which promote and improve the processing ability and application level of point cloud data. However,at present,the commercial hardware still has some deficiencies. Combining 3D point cloud data with observation from other sensors is a valuable but challenging task. Nevertheless,the laser scanning system is expected to be widely used in transportation,civil engineering,forestry,agriculture,and other civil fields in the future to satisfy different detection and modeling tasks. At the same time,with ongoing advancements in laser scanning equipment,it also plays an important role in understanding natural sciences,such as archaeology and geoscience. High dynamic range imaging is a hot research field in digital image acquisition,processing,display,and applications. Currently, researchers mostly focus on multiple exposure,different modulation methods,and multi detector methods in the HDR imaging. For example,through nonlinear response and multiple exposure imaging,the dynamic range can reach approximately 140 dB,and it can reach approximately 160 dB by using multi detector imaging. Using deep learning directly in HDR image mapping,instead of using traditional methodology,such as optical flow method and the combination of optical flow and neural network,has become a distinguished characteristic. Deep learning neural network has also been gradually applied to single exposure HDR reconstruction and tone mapping. Many domestic research teams have investigated the issues for the combination of deep learning neural network and HDR imaging.
