Abstract: This application is applicable to the field of intelligent vehicles, and specifically provides a projection method and apparatus, a vehicle, and an AR-HUD. The projection method includes: obtaining image information and position information of a calibration object; projecting the calibration object based on the image information and the position information of the calibration object and an imaging model; and when an overlap ratio between the calibration object and a projection plane of the calibration object is less than a first threshold, adjusting a parameter of the imaging model. According to this application, an image projected and displayed may be aligned with a real world, which improves a projection display effect.

Abstract: This invention relates to conjugates of camptothecin analogs with a cell-binding molecule of formula (I), wherein R1, R2, R3, R4, R5, X, L, n, m, T and ----- are defined herein. It also provides methods of making the conjugates of camptothecin analogs to a cell-binding agent, as well as methods of using the conjugates in targeted treatment of cancer, infection, and immunological disorders.
