Abstract
(EN) Disclosed in embodiments of the present application are an image projection method and system. The image projection method comprises: obtaining a state of a vehicle at a current time; measuring a condition parameter of an environment where the vehicle is located at the current time, the condition parameter comprising the light intensity in the environment where the vehicle is located; and controlling an image projection device to project an image indicating the state of the vehicle into the environment on the basis of the light intensity in the environment where the vehicle is located. By means of reflecting light of the environment where the vehicle in located and performing vehicle state projection, and selecting different projection modes according to the light intensity in the environment, the image projection method provided in the present application can solve the problem of heat dissipation of an image projection device during the daytime, can save electrical energy, and can be applied in different application scenarios.
(FR) Sont divulgués, dans des modes de réalisation de la présente demande, un procédé et un système de projection d'image. Le procédé de projection d'image consiste : à obtenir un état d'un véhicule à un moment actuel ; à mesurer un paramètre de condition d'un environnement dans lequel se trouve le véhicule au moment actuel, le paramètre de condition comprenant l'intensité lumineuse dans l'environnement où se trouve le véhicule ; à commander un dispositif de projection d'image pour projeter une image indiquant l'état du véhicule dans l'environnement sur la base de l'intensité lumineuse dans l'environnement où se trouve le véhicule. Au moyen de la réflexion de la lumière de l'environnement où se trouve le véhicule et de l'exécution d'une projection d'état de véhicule, et de la sélection de différents modes de projection selon l'intensité lumineuse dans l'environnement, le procédé de projection d'image selon la présente demande peut résoudre le problème de dissipation de chaleur d'un dispositif de projection d'image pendant la journée, peut économiser de l'énergie électrique et peut être appliqué dans différents scénarios d'application.
(ZH) 本申请实施例公开了一种图像投射方法和系统。所述图像投射方法包括:获取当前时间的车辆状态;检测所述车辆所处环境在所述当前时间的状况参数,所述状况参数包括所述车辆所处环境中的光线强度;以及基于所述车辆所处环境中的光线强度,控制图像投射设备将表示所述车辆状态的图像投射至所述环境中。本申请提供的图像投射方法,通过反射车辆所处环境中的光线进行车辆状态投射,并根据环境中的光线强度选择不同的投射模式,可以解决图像投射设备在白天的散热问题,节约了电能,可以适用于不同的应用场景。
