The invention discloses a head-up display device, a head-up display system and traffic equipment. The head-up display device includes an image source, a reflecting element, a partially reflective and partially transmissive element, and at least one sensor. The image source is configured to output light for displaying an image; the reflecting element is configured to reflect and converge the light for displaying the image; the partially reflective and partially transmissive element is arranged in a light path between the image source and the reflecting element; the at least one sensor is positioned on one side, far away from the image source, of the plane of the partially reflective and partially transmissive element; the partially reflective and partially transmissive element is configured to split a light beam which comes from the outside of the head-up display device and is incident to the partially reflective and partially transmissive element into a first sub-light beam and a second sub-light beam with different transmission directions; the first sub-beam is configured to be transmittable toward the image source and the second sub-beam is configured to be transmittable toward the at least one sensor. According to the head-up display device, the sensor does not influence the display effect of the head-up display device.
一种抬头显示装置、抬头显示系统和交通设备。该抬头显示装置包括图像源、反射元件、部分反射部分透射元件以及至少一个传感器。图像源被配置为输出显示图像的光;反射元件被配置为对显示图像的光进行反射和会聚;部分反射部分透射元件设置在图像源至反射元件之间的光路中;至少一个传感器位于部分反射部分透射元件所在平面的远离图像源的一侧;部分反射部分透射元件被配置为可将源于抬头显示装置外部并入射到部分反射部分透射元件的光束分束为传输方向不同的第一子光束和第二子光束;第一子光束被配置为可朝向图像源传输,第二子光束被配置为可朝向至少一个传感器传输。该抬头显示装置使得传感器不影响抬头显示装置的显示效果。
