The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
The pedestrian reminding method and system based on the vehicle-mounted terminal, the storage medium and the vehicle-mounted terminal can remind pedestrians in front of the vehicle to avoid timely through a specific light flashing mode, so that potential safety hazards can be avoided to the maximum extent, the intelligent degree is high, and the user experience is greatly improved.
As shown in fig. 1, in an embodiment, the method for reminding a pedestrian based on a vehicle-mounted terminal of the present invention includes the following steps:
and step S1, receiving the vehicle front image information sent by the vehicle-mounted front image pickup device.
Specifically, a vehicle-mounted front-mounted camera device, such as a camera, is arranged in front of the vehicle and used for collecting image information in front of the vehicle and sending the collected image information in front of the vehicle to a vehicle-mounted terminal. The image information in front of the vehicle is not limited to an image directly in front of the vehicle, but includes an image in a field of view in front of the vehicle. That is, the image information in front of the vehicle includes all images that are expanded in front of the vehicle to the left and right by a certain angle, so that the image information in front of the vehicle includes not only pedestrian information immediately in front of the vehicle but also pedestrian information that is about to go in front of the vehicle and immediately before the vehicle.
In an embodiment of the present invention, the vehicle-mounted front-end camera device is connected to the vehicle-mounted terminal in a wired or wireless manner. When the connection is carried out in a wired mode, data communication CAN be carried out through the CAN bus; when the connection is made in a wireless manner, data communication can be performed in a WiFi manner, a bluetooth manner, or the like.
And step S2, recognizing the image information in front of the vehicle.
Specifically, the vehicle-mounted terminal performs image recognition on the image information in front of the vehicle to judge whether the image information in front of the vehicle contains pedestrian information. Image recognition refers to a technique for processing, analyzing and understanding images to recognize various different patterns of objects and objects. In general industrial use, an industrial camera is adopted to shoot pictures, and then software is utilized to further identify and process the pictures according to the gray level difference of the pictures. For those skilled in the art, image recognition is a mature prior art, and therefore, is not described in detail herein.
And step S3, when the image information in front of the vehicle contains pedestrians, controlling the headlights of the vehicle to emit light according to a preset mode so as to remind the pedestrians to avoid the vehicle.
Specifically, when the image recognition shows that the image information in front of the vehicle contains a pedestrian, the vehicle-mounted terminal sends control information to a vehicle control system, so that the vehicle control system controls a headlight of the vehicle to emit light according to a preset mode. When the pedestrians see the light in the preset mode, the pedestrians are aware of the need to avoid the vehicles around the pedestrians in time, and therefore potential safety hazards which may exist are avoided as far as possible.
In an embodiment of the invention, the preset manner includes one or more combinations of a preset illumination shape, a preset illumination height, a preset illumination color, a preset lamp group switching sequence, and a preset illumination direction. Specifically, the illumination shape, the illumination height, the lamp group switching sequence and the illumination direction of the vehicle headlamp can be set according to requirements. When the pedestrians are reminded to avoid the vehicle, the vehicle-mounted terminal controls the front lamp of the vehicle to emit light according to a preset mode, and therefore specific light beams are generated to remind the pedestrians.
In order to further ensure the safety of the vehicle during driving, in an embodiment of the present invention, the method for reminding pedestrians based on the vehicle-mounted terminal further includes controlling the vehicle to send out reminding information and/or decelerate when the image information in front of the vehicle contains pedestrians. When the vehicle headlights are lighted according to the preset mode, pedestrians can still not avoid in time, so the vehicle-mounted terminal simultaneously sends control information to the vehicle control system, so that the vehicle control system controls the vehicle to decelerate, and the safety of the pedestrians is ensured. When the vehicle headlights are lighted in a preset mode, pedestrians may avoid without consciousness in time, and therefore the vehicle-mounted terminal simultaneously sends control information to the vehicle control system, so that the vehicle control system reminds the pedestrians again in a voice or whistle mode.
As shown in fig. 2, in an embodiment, the pedestrian reminding system based on the vehicle-mounted terminal of the invention includes a receiving module 21, an identifying module 22 and a reminding module 23.

That is, the image information in front of the vehicle includes all images that are expanded in front of the vehicle to the left and right by a certain angle, so that the image information in front of the vehicle includes not only pedestrian information immediately in front of the vehicle but also pedestrian information that is about to go in front of the vehicle and immediately before the vehicle.
In an embodiment of the present invention, the vehicle-mounted front-end camera device is connected to the vehicle-mounted terminal in a wired or wireless manner. When the connection is carried out in a wired mode, data communication CAN be carried out through the CAN bus; when the connection is made in a wireless manner, data communication can be performed in a WiFi manner, a bluetooth manner, or the like.
The recognition module 22 is connected with the receiving module 21 and is used for recognizing the image information in front of the vehicle.
Specifically, the vehicle-mounted terminal performs image recognition on the image information in front of the vehicle to judge whether the image information in front of the vehicle contains pedestrian information. Image recognition refers to a technique for processing, analyzing and understanding images to recognize various different patterns of objects and objects. In general industrial use, an industrial camera is adopted to shoot pictures, and then software is utilized to further identify and process the pictures according to the gray level difference of the pictures. For those skilled in the art, image recognition is a mature prior art, and therefore, is not described in detail herein.
The reminding module 23 is connected with the recognition module 22 and is used for controlling the front lamp of the vehicle to emit light according to a preset mode when the image information in front of the vehicle contains pedestrians so as to remind the pedestrians to avoid the vehicle.
Specifically, when the image recognition shows that the image information in front of the vehicle contains a pedestrian, the vehicle-mounted terminal sends control information to a vehicle control system, so that the vehicle control system controls a headlight of the vehicle to emit light according to a preset mode.
