Summary: Machine perception uses advanced sensors to collect information for situational awareness. State-of-the-art machine perception faces difficulties with increasing number of intelligent agents. Exploiting omnipresent heat signal could be a new frontier for scalable perception. The proposed heat-assisted detection and ranging (HADAR) overcomes the challenge of ghosting and shows promising results compared to AI-enhanced thermal sensing.

Summary: This study investigates the effectiveness of using LiDAR data combined with statistical and plant structure features, along with ground reference values, to estimate LAI for sorghum and maize at different times using wheeled vehicles and drones. Predictive models show R-2 results ranging from around 0.4 in the early season to 0.6 to 0.80 for sorghum and maize in more mature growth stages.

Summary: This study aims to assess the predictive ability of metrics derived from different types of high-resolution remote sensing (RS) products for the habitat suitability of wetland birds. The results show that ALS and Sentinel metrics improve the accuracy of species distribution models (SDMs) for wetland bird species by 11% and 10% of the area under curve (AUC) respectively. The importance of different RS products varies among species.

Summary: A berthing information extraction system based on 3D LiDAR technology has been developed, which utilizes principal component analysis to calculate a ship's heading and normal vector, identify feature points of the bow and stern, and obtain segments passing through these points through region growing. Qualitative and quantitative analyses of the distance, velocity, and approach angle of dynamic ship targets relative to docks are conducted to ensure safe ship berthing, demonstrating the feasibility and effectiveness of the proposed method.

Summary: The popularity of smartphones and advancements in sensor technologies have created new possibilities for scientific applications and cost-effective observations. This study proposes a new methodology using the LiDAR sensor in the Apple iPhone XR to examine wall cracks and resulting displacement. Dedicated spatial measurement targets (SMTs) were used to measure quasi-flat and homogeneous walls. The methodology includes smartphone measurements with and without SMTs, and their analysis compared to terrestrial laser scanner (TLS) measurements. The analysis shows that smartphone measurement with LiDAR and SMT is better than TLS for detecting small cracks such as 0.5-1.0 mm.

Summary: This paper introduces and realizes a 3D imaging method based on compressed sensing technology and dual-frequency laser phase ranging. The time-domain light intensity signal collected by a single-point detector is used for two-dimensional range reconstruction using compressed sensing algorithm. By solving the phase information of the two-dimensional spatial distribution in the time-domain signal, the 3D image information of the target scene is inverted, achieving the effect of scan-free 3D imaging. The feasibility of the system is verified through simulations and different reconstruction algorithms are compared. A non-scanning 3D imaging experimental platform is designed and built, successfully reconstructing 3D images of multiple objects with 32x32 resolution.
