During attached drawing, unless otherwise indicated, the same numbers in different attached drawings represent the same or similar element.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the disclosure.On the contrary, they be only with it is such as appended
The example of the consistent apparatus and method of some aspects be described in detail in claims, the disclosure.
The embodiment of the present disclosure provides a kind of collision warning systems on automobile, wherein, collision warning systems
Referred to as frontal collisions early warning system when being that one kind detects Ben Che and front truck by potential risk of collision, is reminded, to prevent or
Reduce the alarm system of traffic accident.
As shown in Figure 1, collision warning systems include camera 1 and processor 2, wherein：Processor 2 is electrical with camera 1
Connection；The obstructions chart picture of acquisition is sent to processor 2 by camera 1 for gathering obstructions chart picture；Processor 2 is used for
Obstructions chart picture based on multiframe, determines collision prediction duration, if collision prediction duration is less than or equal to default value,
Alarm command is sent to the warning piece 3 being electrically connected with processor 2, so that warning piece 3 sends alarm signal.
Wherein, warning piece 3 may belong to collision warning systems, such as one can be set to raise one's voice in collision warning systems
Device etc., warning piece 3 can also be the component of automobile in itself, such as can be internal loudspeaker, can also be the instrument of automobile
Disk etc..
In force, which is typically mounted on the room mirror pedestal of automobile, wherein 1 court of camera
The direction advanced to automobile.As shown in Fig. 2, processor 2 is also electrically connected with warning piece 3, warning piece 3 is used to send alarm
Signal is to remind driver.Camera 1 can gather the obstructions chart picture of vehicle front, and the obstructions chart picture of acquisition is sent
To processor 2, obstructions chart picture of the processor 2 based on continuous multiple frames using image processing algorithm, such as optical flow method, determines collision
It is expected that duration.Wherein collision prediction duration that is to say, the duration that following duration Nei Benche collides with barrier.If this is touched
Estimated duration is hit less than default value, then processor 2 can be to the transmission alarm command of warning piece 3, and warning piece 3 is based on alarm
Instruction sends alarm signal.Wherein, above-mentioned alarm signal can audibly, can also be in a manner of vision, can also
