    摘要： Embodiments of the present invention provide a negative electrode material, including a doped carbon material. The doped carbon material includes a carbon-based matrix and doping elements doped in the carbon-based matrix. The doping elements include at least two of B, N, O, P, S, and F. At least a part of the doping elements form C-Ma-Mb chemical bonds with the carbon-based matrix. Ma and Mb represent two different types of doping elements. The negative electrode material includes the doped carbon material, and the doping elements in the doped carbon material form the C-Ma-Mb chemical bonds with the carbon-based matrix. Therefore, the negative electrode material has excellent fast charging performance. Embodiments of the present invention further provide a production method of the negative electrode material, a battery including the negative electrode material, and a terminal.

    摘要： A road information detection method is provided, which is used for vehicle road information detection. The method may be applied to automatic driving or intelligent driving, for example, an advanced driver assistance system ADAS. The method includes: receiving a front-looking image (301) from at least one front-looking camera apparatus (101) and a rear-looking image (302) from at least one rear-looking camera apparatus (102); obtaining front-looking lane line information (303) based on the front-looking image; obtaining rear-looking lane line information (304) based on the rear-looking image; and obtaining target lane line information (305) based on the front-looking lane line information and the rear-looking lane line information. In this method, reliability of determining lane line information in a cooperative vehicle infrastructure system can be improved, thereby improving driving safety performance.

    摘要： This application discloses an obstacle detection method, including: obtaining a first image, where the first image is an image encoded based on an RGB model; reconstructing the first image to obtain a second image, where the second image is a hyper spectral image; and extracting a hyper spectral feature from the hyper spectral image, and classifying a candidate object in the hyper spectral image based on the hyper spectral feature to obtain an obstacle detection result. Because different textures correspond to different hyper spectral features, classifying candidate objects in hyper spectral images based on the hyper spectral features can distinguish an object that has a similar color but a different texture. On this basis, an obstacle that has a color same as or similar to that of an environment can be detected, thereby reducing a detection miss rate. In addition, in the method, a common camera may be used to obtain hyper spectral images in a manner of image reconstruction, without using an imaging spectrometer. Therefore, a cost is low and feasibility is high. This application further discloses a corresponding apparatus, device, and medium.
