| 1 | 高光谱激光雷达:三维生物物理化学生态测量学显示文摘生态测量学为生态学、地理学、林学、野生生物学等提供基础的技术支撑,开发适应上述学科发展的新型生态测量技术日渐重要,尤其随着目前生物地球化学的快速推进,开发三维生物物理化学生态测量技术成为当前的研究热点,然而当前的主流遥感测量技术仍无法做到高效准确。高光谱激光雷达技术的发展为解决该问题提供了可能,这也通过基于连续测量的3种单木高光谱激光雷达数据实现反演光合有效辐射、树冠叶绿素含量与氮含量的三维分布及其昼夜变化趋势得到验证。实验结果预示随着高光谱激光雷达的成熟,三维生物物理化学生态测量学将得以建立,相应的三维生物物理化学生态测量技术将进一步推动地理学、生态学、生物地球化学乃至地球系统科学的发展。 | 林沂 Eetu PUTTONEN Juha HYYPPA | 2017 | 遥感信息2017，32，1： | 6 |
| 2 | A practical method utilizing multi-spectral LiDAR to aid points cloud matching in SLAM显示文摘Light Detection and Ranging(LiDAR)sensors are popular in Simultaneous Localization and Mapping(SLAM)owing to their capability of obtaining ranging information actively.Researchers have attempted to use the intensity information that accompanies each range measurement to enhance LiDAR SLAM positioning accuracy.However,before employing LiDAR intensities in SLAM,a calibration operation is usually carried out so that the intensity is independent of the incident angle and range.The range is determined from the laser beam transmitting time.Therefore,the key to using LiDAR intensities in SLAM is to obtain the incident angle between the laser beam and target surface.In a complex environment,it is difficult to obtain the incident angle robustly.This procedure also complicates the data processing in SLAM and as a result,further application of the LiDAR intensity in SLAM is hampered.Motivated by this problem,in the present study,we propose a Hyperspectral LiDAR(HSL)-based-intensity calibration-free method to aid point cloud matching in SLAM.HSL employed in this study can obtain an eight-channel range accompanied by corresponding intensity measurements.Owing to the design of the laser,the eight-channel range and intensity were collected with the same incident angle and range.According to the laser beam radiation model,the ratio values between two randomly selected channels’intensities at an identical target are independent of the range information and incident angle.To test the proposed method,the HSL was employed to scan a wall with different coloured papers pasted on it(white,red,yellow,pink,and green)at four distinct positions along a corridor(with an interval of 60 cm in between two consecutive positions).Then,a ratio value vector was constructed for each scan.The ratio value vectors between consecutive laser scans were employed to match the point cloud.A classic Iterative Closest Point(ICP)algorithm was employed to estimate the HSL motion using the range information from the matched point clouds.According to the test results,we found that pink and green papers were distinctive at 650,690,and 720 nm.A ratio value vector was constructed using 650-nm spectral information against the reference channel.Furthermore,compared with the classic ICP using range information only,the proposed method that matched ratio value vectors presented an improved performance in heading angle estimation.For the best case in the field test,the proposed method enhanced the heading angle estimation by 72%,and showed an average 25.5%improvement in a featureless spatial testing environment.The results of the primary test indicated that the proposed method has the potential to aid point cloud matching in typical SLAM of real scenarios. | Changhui Jiang Yuwei Chen Wenxin Tian Ziyi Feng Wei Li Chunchen Zhou Hui Shao Eetu Puttonen Juha Hyyppä | 2020 | Satellite Navigation2020，1，1： | 2 |
