Embodiment 1

[0044] image 3 It is a schematic flowchart of a method for identifying road conditions through a driving recorder provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation where a driving recorder is used to assist in identifying road conditions during vehicle driving. The method can be implemented by a It is executed by a device for road condition recognition by a driving recorder, which is implemented by software and / or hardware, and generally can be configured on a driving recorder. Such as image 3 The shown method specifically includes the following steps:

[0045] S110. Obtain light intensity information of the external environment of the vehicle;

[0046] Wherein, the driving recorder acquires the light intensity information of the external environment where the vehicle is located during the driving process of the vehicle. There is no limitation on the specific form and acquisition method of the external light intensity inform...

Embodiment 2

[0055] Figure 4A It is a schematic flowchart of a method for identifying road conditions through a driving recorder provided in Embodiment 2 of the present invention. This embodiment is further optimized on the basis of the foregoing embodiments. Optimize "obtaining the light intensity information of the external environment of the vehicle" to "obtain the light intensity information of the environment in which the vehicle is located through a light sensor; use the light intensity information as the light intensity information of the external environment". The method specifically includes the following steps:

[0056] S210A. Obtain light intensity information in the environment where the vehicle is located through a light sensor;

[0057] In this step, the driving recorder is equipped with a light sensor, and the light sensor is used to collect the light intensity information of the environment where the vehicle is located, and the light intensity information is used as the l...

Embodiment 3

[0093] Figure 5 The third embodiment of the present invention provides a schematic structural diagram of a system for road condition recognition through a driving recorder. This embodiment can be used in the case of using a driving recorder to assist in road condition recognition during vehicle driving. The system includes: light intensity information An acquisition module 310 , a thermal imaging image acquisition module 320 and a road condition prompt module 330 .

[0094] Wherein, the light intensity information acquisition module 310 is used to acquire the light intensity information of the external environment of the vehicle;

[0095] The thermal imaging image acquisition module 320 is configured to turn on the infrared sensor to acquire the thermal imaging image in the set detection area in front of the vehicle when the external ambient light intensity information meets the preset auxiliary identification conditions;

[0096] The road condition prompting module 330 is c...

Abstract

The embodiment of the invention discloses a method and system for identifying road conditions through a driving recorder. The method includes: obtaining the light intensity information of the external environment of the vehicle; when the light intensity information of the external environment satisfies a preset auxiliary identification condition, turning on the infrared sensor to obtain a thermal imaging image in a set detection area in front of the vehicle; Obstacles identified in the image will prompt the driver of the vehicle on the road conditions. The above technical solution solves the problem that the driving recorder can only record the video information of the surrounding environment during the driving process of the vehicle, and cannot assist the driver to identify the road conditions when driving at night, and realizes the informatization and intelligence of the driving process of the vehicle. Effectively reduce safety risks, ensure driving safety, and enhance the driver's driving experience.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle equipment, and in particular to a method and system for identifying road conditions through a driving recorder. Background technique [0002] With the advancement of science and technology, the concept of "intelligent transportation system" has become a new research field, and it has rapidly developed into a new information-based, intelligent and socialized transportation system. The rise of intelligent transportation systems has improved the level of traffic safety, reduced the possibility of accidents and avoided accidents. At the same time, with the occurrence of various moral decline incidents in recent years and the chaotic traffic in the city, more and more car owners install driving recorders in their cars to better protect their legal rights on the way. [0003] In the process of realizing the present invention, the inventor found that the prior art has the following...
