Automobile monitoring method and system

Abstract

The invention discloses an automobile monitoring method and system. The method comprises the following steps: acquiring a current vehicle speed in response to a monitoring startup request, wherein the monitoring startup request is triggered by a driving signal for operating a vehicle; determining the range of the current vehicle speed, and determining a picture mode for displaying on an automobile monitoring picture according to the range and the driving signal for triggering the monitoring startup request; acquiring camera data, screening and integrating the acquired camera data according to the picture mode, and matching pre-selected 3D car model data into the screened and integrated camera data to generate a corresponding view to be displayed on the automobile monitoring picture, wherein the view is a real-scene image obtained by observing from a virtual viewpoint correlated with the view to the location of the 3D car model data. A camera is started up intelligently to generate the picture mode consistent with the driving intent of a driver, so that the driver can observe the surrounding situation of the vehicle more easily, and driving accidents are avoided.

Description

technical field [0001] The invention relates to the technical field related to automobiles, in particular to an automobile monitoring method and system. Background technique [0002] Existing car monitoring methods can acquire images through multiple cameras installed on the vehicle to form a surrounding view monitor (AVM for short) monitoring screen, so that the driver can confirm the safety around the vehicle through the monitoring screen. [0003] However, the existing monitoring screens are relatively simple, and often have the following problems or limitations: [0004] 1. Generally, there are only a few simple screen display modes, such as front view, rear view, and top view. The screen angle is monotonous, and it cannot respond to different driving scenarios in a targeted manner, and the user experience is not good. [0005] 2. If figure 1 As shown in the top view, the combination of 2D car model and 2D camera data is used. However, since the driving environment act...

Problems solved by technology

[0003] However, the existing monitoring screens are relatively simple, and often have the following problems or limitations:

[0004] 1. Generally, there are only a few simple screen display modes, such as front view, rear view, and top view. The screen angle is monotonous, and it cannot respond to different driving scenarios in a targeted manner, and the user experience is not good.

[0005] 2. If figure 1 As shown, in the top view, the combination of 2D car model and 2D camera data is used. However, since the driving environment actually seen by the human eye is three-dimensional, this 2D display mode is difficult to realistically simulate the actual driving environment. Intuitive and comprehensive understanding of the surrounding environment of the vehicle

[0006] 3. If figure 2 As shown, some monitoring screens also combine the video images on the left or right side of the vehicle, so that the driver can see more of the left or right side of the vehicle, but these left or right video images are directly used The data captured by the camera on the left side of the vehicle or the camera on the right side of the vehicle can only see the driving environment in a small range on one side of the vehicle in each view. The field of view of a single view is extremely limited. If you want to understand the surrounding environment of the vehicle, you must monitor it Multiple views are displayed on the screen, and the monitoring screen appears complicated and messy, which will affect the user's driving attention

Moreover, this monitoring picture still cannot intuitively provide the real scene effect combined with the vehicle
