no. 1 example

[0056] see figure 1 , which is a flow chart of the method for intelligent terrain recognition provided in this embodiment.

[0057] The intelligent terrain recognition method provided in this embodiment specifically includes the following steps:

[0058] S101: Acquiring an image of a preset driving range of the driving area in front of the vehicle.

[0059] It can be understood that the preset driving range does not need to be set too large. Generally, it is enough to set a predetermined width and distance in front of the vehicle. For example, it is enough to obtain images within the area of ​​10 meters in width and 20 meters in front of the vehicle.

[0060] In this embodiment, the preset driving range can set different image acquisition ranges for different types of vehicles to adapt to the structure of different vehicles, so that ideal images can be acquired for subsequent image processing and more accurate data.

[0061] Examples of vehicle types include: off-road vehicl...

[0079] see Figure 2A , which is a flowchart of a specific implementation method of S102 provided in this embodiment.

[0080] Include the following steps:

Embodiment 1

[0081] S102 in Embodiment 1 includes:

[0082] S201: Perform pixel analysis on the image by using a deep neural network, and segment a ground area from the image.

[0083] In this embodiment, an optional image acquisition method is provided, which specifically includes: acquiring an image of a preset driving range of the driving area in front of the vehicle through a camera installed in front of the vehicle, and setting the preset driving range by setting the parameters of the camera scope.

[0084] Wherein, the parameters of the camera may include internal parameters and external parameters. The internal parameters include the focal length fx, fy, x0, y0 as the main point coordinates (relative to the imaging plane), s is the coordinate axis tilt parameter, etc. The external parameters include rotation matrix and translation matrix, etc. Different camera parameters are set for different vehicles so that the camera can capture images with a reasonable preset driving range.

Abstract

The invention discloses a method and a device of intelligently recognizing a terrain, a vehicle-mounted terminal and a vehicle. The method includes: acquiring an image of a preset driving range of a driving area in front of a vehicle; extracting a road surface feature from the image; judging a type of a road surface according to the extracted road surface feature; and thus enabling the vehicle toselect a corresponding driving strategy according to the type of the road surface. Through the method provided by the embodiment of the invention, the vehicle can intelligently recognize the type of the current road surface, and automatically switch a driving strategy of the vehicle for the road surface type, convenience of an adaptation function of the vehicle on the terrain is greatly improved,driving experience is improved, and probability of occurrence of safety hidden-troubles is reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent driving, in particular to a method, device, vehicle-mounted terminal and vehicle for intelligently recognizing terrain. Background technique [0002] In the actual driving experience, the vehicle will provide corresponding driving strategies for different terrain conditions when it leaves the factory. It can be used as an input for automatic emergency braking (AEB) to improve driving safety. On the one hand, for the consideration of comfort, it provides users with a comfortable, stable, fuel-efficient and energy-saving driving strategy. That is to say, for different terrains, such as roads, sand, snow, mud, grass, etc., by adjusting vehicle-related parameters, different terrains can correspond to different driving strategies, which can not only provide users with a good driving experience, but also Can reduce the damage to the vehicle. [0003] At present, the choice of driving strategy mai...
