Abstract In this article, a novel necking detection and measurement method for automotive sheet metal components is proposed to detect measure necking. The utilizes point cloud registration-based approach achieve better defect performance in the region of interest. method, an efficient registration algorithm called global feature-iterative closest introduced, which exhibits excellent complex surfaces, such as parts. Subsequently, normal vector propagation extraction, enabling acquisition...
Shallow water bathymetry is essential for maritime navigation, environmental monitoring, and coastal management. While traditional methods such as sonar airborne LiDAR provide high accuracy, their cost time-consuming nature limit application in remote sensitive areas. Satellite sensing offers a cost-effective rapid alternative large-scale bathymetric inversion, but it still relies on significant situ data to establish mapping relationship between spectral depth. The ICESat-2 satellite, with...
A minimized and efficient low temperature loading device cooling with Peltier coolers for indentation test is developed. Both specimen tip are immersed in 50% methanol-water solution, totally eliminating the contact thermal drift problem. Low tests down to 253.8 K can be realized within 10 min. The size of miniaturized 50 × 40 30 mm3, no vacuum environment required. Monocrystalline copper tested perform feasibility device. Based on simple structure stable experimental effect, developed...
