Recently, various calibration techniques proposed for extrinsic calibration for Autonomous Vehicles (AVs) mostly rely on the camera 2D images and depth map to calibrate the 3D LiDAR points. While most methods work with the whole frame, some methods use the objects in the frame to perform the calibration.

Taking research to the bank Behind the doors of BAE Systems' Advanced Technology Center. Testing toward perfection In a competitive global market, commercial aircraft need to be lighter, faster to market, cheaper to build, easier to maintain, and safer than ever.

While good results have been obtained by others using a Total Station or LiDAR to physically measure locations for such purposes, this approach could prove difficult if a site of interest is inaccessible (e.g. on a busy highway that cannot be shut down) or if relevent features of the target location have changed (e.g. due to construction or even restriping of lanes lines).

In recent years, vehicle-intelligent road cooperation is gaining an increasing attention from both academia and industry, which require deployment of a large scale of road side sensors such as lidar and camera. For the road side sensors, calibration is indispensable to obtain transformation between sensor coordinate frame and geographic coordinate frame. ...To simplify the calibration task and improve efficiency, an automatic calibration method for road side lidar and camera using a planar calibration target is proposed in this paper. The feature of planar target is designed to be easily identified by the sensors, and an Integrated Navigation System (INS), which acquires the geographic coordinate of itself in real time at an accuracy of centimeter level, is fixed on the target. ...The experiment results show that the proposed calibration method is able to calibrate road side lidar and camera efficiently and accurately.

Hardware mounted on the roof that are used to support cameras and LIDAR sensors, and mechanisms meant to keep that hardware clean and functioning, add even further noise contamination that can pollute the voice interaction.

Then there were two Prevailing sentiment in the Japanese media, and to some extent among the public, is that there are two truly indigenous automobile manufacturers in Japan: the Toyota group of companies and Honda. Others have entrenched themselves in global alliances for much-needed infusions of foreign capital. Cars and light trucks merge As light-vehicle segments blur in function and utlility, Japanese manufacturers are placing body design emphasis on optimum space utilization and crash safety. Chassis trends Technologies in development by Japanese companies include lane keeping, steer by wire, and dynamic stability via hybrid-electric drive. Engines and electric motors The Japanese industry is pursuing a high-tech mix of internal combustion engines, hybrid IC/electric powertrains, and fuel cells.
