Description

Technical Field

[0001] The utility model relates to the technical field of HUD, and more specifically, to a HUD structure controlled by gestures shot by a camera. Background Art

[0002] With the rapid development of automobile technology, the head-up display (HUD) system has become an important feature in modern cars. It improves driving safety by displaying information such as vehicle speed and navigation on the front windshield, so that drivers do not need to look down at the dashboard while driving. However, traditional HUD systems have some limitations and inconveniences.

[0003] Traditional HUD systems usually use photometric sensing technology to automatically adjust the brightness according to the ambient light intensity. Although this technology can ensure that the HUD display content has appropriate readability under different lighting conditions, it cannot adapt to the driver's personalized needs. For example, drivers may have different preferences for brightness under different lighting conditions. In addition, when switching other functions of the HUD, the driver usually needs to manually press buttons or touch screens, which not only distracts the driver's attention and increases driving risks, but also makes the operation cumbersome and reduces the driving experience. Therefore, we have made improvements to this and proposed a HUD structure that controls gestures through camera shooting. Utility Model Content

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0036] Embodiment 1 of the utility model controlling the HUD structure by shooting gestures with a camera

[0037] Please refer to Figure 1-Figure 2 The utility model controls the HUD structure by shooting gestures with a camera, including: a HUD host 1, a secondary reflector 3 and a primary reflector 2 located above the HUD host 1, a gesture capture camera 5 is arranged between the primary reflector 2 and the HUD host 1, and the gesture capture camera 5 and the HUD host 1 are both connected to the vehicle control system, the gesture capture camera 5 is used to collect the driver's gestures so that the vehicle control system can control the HUD host 1 according to the driver's gestures, the application sets a gesture capture camera 5, and the gesture capture camera 5 is located within the reverse light path range of the HUD host 1, so that the gesture capture camera 5 can capture the driver's gestures, and the driver can control the HUD host 1 through simple gestures to adapt to different lighting conditions and personal preferences, thereby improving the readability and comfort of the HUD; the driver does not need to manually press buttons or touch screens, but can complete the switching of HUD functions through gestures, which makes the operation more convenient and reduces the driver's distraction during driving.

[0038] When in use, for the convenience of description and understanding, this application uses G to represent the front windshield and E to represent the driver. The image of the HUD host 1 is refracted by the primary reflector 2 and the secondary reflector 3 and then projected onto the front windshield, and then refracted by the front windshield to the driving driver. The driver's gesture is refracted by the windshield to the secondary reflector 3, and then refracted by the primary reflector 2 to the gesture capture camera 5. The gesture capture camera 5 can capture the driver's gesture and pass the gesture data to the vehicle control system. The vehicle control system controls the HUD host 1 according to the corresponding instructions of the preset gesture.

[0039] Further, such as Figure 4 As shown, the gesture capture camera 5 is arranged on the HUD host 1, so that the gesture capture camera 5 and the HUD host 1 are arranged together, thereby making it unnecessary to install the gesture capture camera 5 additionally.
