Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] refer to Figure 1~Figure 4 , an augmented reality driving assistance warning system, including a vehicle camera unit, a central processing unit, and a head-up display unit. The vehicle-mounted camera unit includes a front-view camera and two face cameras, wherein the front-view camera is arranged in front of the center rearview mirror for photographing road conditions ahead; the face cameras are symmetrically built in the middle of the instrument panel for To capture the driver's head information. The patterns captured by the three cameras will be transmitted to the central processing unit for processing.

[0022] The central processing unit is arranged in the center console of the vehicle, and it will first identify the specific position of the external risk factor according to the specific image content of the front-view camera, and mark the corresponding p...

Abstract

The invention discloses an actually-enhanced driver-assisted early warning system, which comprises a vehicle camera unit, a central processor unit and a head-up display unit. The vehicle camera unit comprises a front camera for shooting circumstance of a road ahead and two face cameras for shooting head information of a driver, wherein the front camera is arranged in the front of a middle-rear view mirror; the face cameras are arranged in an instrument panel symmetrically; and the three cameras are connected with the central processor unit. The central processor unit is used for identifying the specific locations of external risk factors according to the specific image contents of the front camera, and marking the locations in the images. The head-up display unit is arranged in the front of a steering wheel and below a front windshield and is used for projecting modified identification information to the front windshield together with warning prompt patterns after receiving an early warning command. The actually-enhanced driver-assisted early warning system can effectively avoid the distraction of the driver so as to improve an early warning effect.

Description

technical field [0001] The invention relates to a driving assistance warning system. Background technique [0002] With the attention to car safety performance, various driving assistance warning systems such as forward collision avoidance warning system and lane departure warning system have been applied more and more. Give the driver corresponding warning or prompt information before the situation occurs, so as to avoid the occurrence of accidents. But for the current driving assistance early warning system, there are two problems in the early warning. One, these early warning signals are mostly arranged on the instrument panel, which, while causing a burden on the necessary space of the instrument panel, also requires the driver to divert the line of sight to check its alarm content, which is easy to disperse the driver's attention, thereby causing new problems. security risks. Second, the warning information of the commonly used early warning systems is similar, which...
