Embodiment Construction

[0079] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0080] see figure 1 , a schematic flowchart of a driving reminder method according to an embodiment of the present disclosure. It includes the following steps:

[0081] In step 11, road images are collected in real time.

[0082] In the embodiments of the present disclosure, by setting a camera and a time-of-flight (TOF) sensor on the vehicle, road images on the vehicle's traveling road are collected in real time. Among them, the time-of-flight (TOF) sensor can be used to obtain the depth image of the road image. A TOF sensor is an array or collection of TOF pixel sensors. The TOF sensor can be a light sensor, a phase detector, etc., to detect the time-o...

Abstract

The present disclosure discloses a driving reminder method, device and vehicle. The method includes: collecting road images in real time; performing preprocessing on the collected road images; performing stop line recognition according to the preprocessed images; , determine the target image; determine the region of interest in the target image for traffic signal recognition; and perform driving reminders according to the stop line recognition result and the traffic signal recognition result. This disclosure collects the road image in front of the vehicle in real time, recognizes the stop line and the traffic signal light on the road image, and makes corresponding judgments in combination with the running information of the vehicle, so as to provide the driver with driving under different conditions when crossing the intersection. The reminder greatly improves the accuracy of the driver's driving judgment.

Description

technical field [0001] The present disclosure relates to the technical field of automobile control, in particular, to a driving reminder method, device and vehicle. Background technique [0002] With the rapid development of automotive electronic products, the safe driving of vehicles is becoming more and more important. For complex driving environments such as traffic intersections, driving reminders play an important role in driving safety. [0003] In the intersection driving reminder in the related art, the processing of traffic light targets is generally limited to recognition, and is limited to distinguishing a single traffic light target. That is, the embedded processor in the vehicle processes the images collected by the camera, including the road conditions at the intersection, and then makes an early warning judgment, and sends early warning information to the user according to the judgment result, as a means of assisting the driving of the vehicle. However, ther...
