Abstract
(EN) Disclosed in the present application are a laser emission method and apparatus, a detection apparatus and a mobile platform, which are applied to autonomous driving or aided driving. The laser emission apparatus comprises a light beam generation apparatus and an optical component. The light beam generation apparatus is used for generating a first light beam and a second light beam, wherein the first light beam is incident to the optical component and is emitted from the optical component, the second light beam is incident to the optical component and is emitted from the optical component, and a first light spot formed by the first light beam in a space is separated, in a horizontal direction, from a second light spot formed by the second light beam in the space. Two light spots emitted by a laser emission apparatus are separated from each other in a horizontal direction, and echoes of the two corresponding light spots are also separated from each other in the horizontal direction, thereby being conducive to avoiding the problem of generating symmetric ghost images, and thus being conducive to improving the identification accuracy of laser radar. The present application can be applied to the Internet of vehicles, such as vehicle to everything (V2X), long term evolution-vehicle (LTE-V) and vehicle-to-vehicle (V2V).
(FR) La présente invention concerne un procédé et un appareil d'émission laser, un appareil de détection et une plateforme mobile, qui sont appliqués à une conduite autonome ou à une conduite assistée. L'appareil d'émission laser comprend un appareil de génération de faisceau lumineux et un composant optique. L'appareil de génération de faisceau lumineux sert à générer un premier faisceau lumineux et un second faisceau lumineux, le premier faisceau lumineux étant incident sur le composant optique et étant émis à partir du composant optique, le second faisceau lumineux étant incident sur le composant optique et étant émis à partir du composant optique, et un premier point lumineux formé par le premier faisceau lumineux dans un espace étant séparé, dans une direction horizontale, d'un second point lumineux formé par le second faisceau lumineux dans l'espace. Deux points lumineux émis par un appareil d'émission laser sont séparés l'un de l'autre dans une direction horizontale, et les échos des deux points lumineux correspondants sont également séparés les uns des autres dans la direction horizontale, ce qui permet d'éviter le problème de génération d'images fantômes symétriques et donc d'améliorer la précision d'identification d'un radar laser. La présente invention peut être appliquée à l'Internet des véhicules, tel que le véhicule à tout (V2X), le véhicule d'évolution à long terme (LTE-V) et le véhicule à véhicule (V2V).
(ZH) 本申请公开了一种激光发射方法、装置、探测装置及移动平台,应用于自动驾驶或辅助驾驶。该激光发射装置包括:光束产生装置和光学组件;光束产生装置,用于产生第一光束和第二光束;第一光束入射光学组件且从所述光学组件出射,第二光束入射光学组件且从光学组件出射,且第一光束在空间所形成的第一光斑和第二光束在空间所形成的第二光斑在水平方向分离。由于激光发射装置发射出的两束光斑在水平方向上分离,相应的两束光斑的回波也会在水平方向产生分离,有助于避免产生对称鬼像的问题,从而有助于提供激光雷达的识别精度。可以应用于车联网,如车辆外联V2X、车间通信长期演进技术LTE-V、车辆-车辆V2V等。
