The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that, in the following examples and embodiments, features may be combined with each other without conflict.
Referring to fig. 1, an embodiment of the present application provides a vehicle vision system, and the vehicle vision system 300 may include a first optical system 310 and an infrared light source 320, where the first optical system 310 includes a visible light source 311, a lamp lens module 312, and a light receiving module. The infrared light source 320 of the present embodiment is disposed at the visible light source 311, and in the present embodiment, the infrared light emitted from the infrared light source 320 and the visible light emitted from the visible light source 311 can be simultaneously emitted through the lamp lens module 312 in a converging manner to illuminate a target in front of the vehicle, which may include, but is not limited to, a person, an obstacle, and the like. Further, the infrared light and the visible light are reflected by the target and then incident on the light receiving module 313, and are condensed and imaged in the light receiving module 313 to obtain a target image. According to the vehicle vision system provided by the embodiment of the invention, the infrared light source 320 is arranged at the visible light source 311, so that the infrared light source 320 and the visible light source 311 share the same vehicle lamp lens module 312, the vehicle lamp space is saved, the vehicle lamp does not need to be specially customized, and the vehicle vision system can be adapted to various vehicles; meanwhile, the same set of light receiving module 313 is used for collecting infrared light and visible light, so that the cost is reduced, the target image collected by the light receiving module 313 not only displays the visible light information of the target but also displays the infrared radiation characteristic information of the target, the content of the target image is rich, the time delay of the target image collecting mode is small, and the distortion of the target image is small.
The visible light source 311 and the infrared light source 320 may be mounted on the same lamp socket, or may be mounted on different lamp sockets, and when the visible light source 311 and the infrared light source 320 are mounted on different lamp sockets, the lamp socket on which the visible light source 311 is mounted and the lamp socket on which the infrared light source 320 is mounted need to be arranged side by side.
The infrared light source 320 is generated by an infrared fill light, the visible light source 311 is generated by a visible light lamp, and the visible light lamp can be a halogen lamp or a xenon lamp. The outer fill light and the visible light lamp of this embodiment are one each.
The visible light of the present embodiment and the lens module 312 cooperate to realize the low beam function and the high beam function of the first optical system 310, wherein one of the low beam function and the high beam function is turned on and the other is turned off at the same time.
In this embodiment, the car light lens module 312 at least includes a light-gathering lens, for example, in one embodiment, the car light lens module 312 includes a light-gathering cup and a light-gathering lens, wherein the light-gathering cup is provided with a groove, which is substantially "bowl" shaped, the visible light source 311 and the infrared light source 320 are disposed in the groove, and the light-gathering lens is installed at an opening of the light-gathering cup and faces the visible light source 311 and the infrared light source 320. The light-gathering cup can gather the visible light emitted by the visible light source 311 and the infrared light emitted by the infrared light source 320 into a parallel mixed light, and then the mixed light is diffused into fan-shaped light through the light-gathering lens.
The condensing lens can be a single-light lens or a double-light lens, and the type of the condensing lens is specifically determined by the structure of the vehicle headlamp. The single optical lens includes a low beam lens and a high beam lens corresponding to the low beam and the high beam, respectively. The bifocal lens is a lens shared by a high beam and a low beam, and can be used as a change similar to the conversion of the high beam and the low beam, and particularly, the switching of the high beam and the low beam is realized through a light shielding sheet in the bifocal lens, for example, when the light shielding sheet is closed, visible light obtains the low beam after passing through the bifocal lens; when the shading sheet is opened, visible light passes through the double-light lens to obtain high beam. The electromagnetic mechanism can be used for operating the opening and closing of the shading sheet.
It should be understood that the vehicle lamp lens module 312 of the present embodiment may also be selected from existing vehicle lamp lens modules.
The infrared light source 320 may be turned on in different ways, for example, in some embodiments, the turning on of the infrared light source 320 and/or the visible light source 311 is controlled in an automatic manner. Referring to fig. 2, the vehicle vision system 300 further includes a processor 330 and an ambient light sensor 340, and the infrared light source 320, the visible light source 311, and the ambient light sensor 340 are electrically connected to the processor 330 respectively. The ambient light sensor 340 is configured to detect an ambient light level, and in some embodiments, the processor 330 turns on the infrared light source 320 when the ambient light level is less than or equal to a preset brightness threshold. In some embodiments, the processor 330 turns on the visible light source 311 in addition to the infrared light source 320 when the ambient light level is less than or equal to the preset brightness threshold. For example, when the vehicle travels at night or in other low-light environments, the intensity of the ambient light detected by the ambient light sensor 340 is less than or equal to the first preset brightness threshold, and at this time, the processor 330 turns on the infrared fill light and controls one of the low beam function and the high beam function to be turned on. Optionally, when the intensity of the ambient light detected by the ambient light sensor 340 is less than or equal to the second preset brightness threshold, the processor 330 controls the high beam function to be turned on, for example, when the vehicle is running in an environment with very poor light such as a high speed or a rural road, and the like, and simultaneously turns on the infrared fill light and the high beam function, so that the illumination intensity is increased by the high beam function, the remote detection under weak ambient light can be realized, and the driving safety under weak light such as a high speed or a rural road and the like is ensured; when the intensity of the ambient light detected by the ambient light sensor 340 is greater than the second preset brightness threshold and less than or equal to the first preset brightness threshold, the processor 330 controls the dipped headlight function to be turned on, for example, when the vehicle is running on an urban road or other environment with weak light, the requirement for safe running of the vehicle can be satisfied by using the dipped headlight function. The first preset brightness threshold and the second preset brightness threshold can be set according to needs. In addition, the installation position of the ambient light sensor 340 can be selected according to the requirement, for example, the ambient light sensor 340 is arranged on the front side of the vehicle head to better detect the ambient light brightness on the front side of the vehicle; of course, the ambient light sensor 340 may also be provided in other areas of the vehicle, for example, by providing the ambient light sensor 340 on the front side of the roof, for example, integrated into a cross member on the front side of the roof. The type of the ambient light sensor 340 is not particularly limited in the embodiments of the present invention, and any sensor capable of detecting the ambient light brightness is within the protection scope of the present invention.
In some other embodiments, the infrared light source 320 and the visible light source 311 are controlled to be turned on manually, for example, referring to fig. 3, the vehicle vision system 300 further includes two control switches 350, wherein one control switch 350 is used for controlling the infrared light source 320 to be turned on and turned off, and the other control switch 350 is used for controlling the visible light source to be turned on and turned off. As shown in fig. 3, the first control switch 351 controls the on/off of the visible light source 311, and the second control switch 352 controls the on/off of the infrared light source 320. Of course, in other embodiments, the infrared light source and the visible light source may be turned on simultaneously by the same control switch, for example, the infrared fill-in light and the dipped headlight function may be turned on simultaneously by the same control switch, or the infrared fill-in light and the high beam function may be turned on simultaneously by the same control switch. The type of the control switch can be selected according to the requirement, and the control switch can be a key, a knob and the like. The control switch can be arranged at a position which is easy to operate by a vehicle driver, for example, a button of the infrared light source 320 can be added to the existing vehicle light control module, the button is used for independently controlling the on-off of the infrared light source 320, in addition, the existing vehicle light control module is also provided with a knob which can control the on-off of the high beam function and the low beam function, when the knob is rotated to a triggering angle corresponding to the low beam function, the low beam function is turned on, and the high beam function is turned off; when the knob is rotated to the triggering angle corresponding to the high beam function, the high beam function is turned on, and the dipped headlight function is turned off. For another example, for the existing knob that is rotated to different angles to correspondingly control the on/off of the high beam function and the low beam function, when the knob is rotated to the triggering angle corresponding to the low beam function and the angle corresponding to the high beam function, the infrared light source 320 is triggered to be turned on at the same time, that is, when the knob is rotated to the triggering angle corresponding to the low beam function, the low beam function and the infrared light source 320 are turned on at the same time; when the knob is turned to the triggering angle corresponding to the high beam function, the high beam function and the infrared light source 320 are turned on simultaneously.
The light receiving module 313 of the present embodiment may be disposed inside a front windshield 3132 of a vehicle, that is, the light receiving module 313 is disposed inside the vehicle, which effectively prevents the light receiving module 313 from being lost, and simultaneously effectively prevents the light receiving module 313 from being worn by an external environment, thereby prolonging the service life of the light receiving module 313; of course, the light receiving module 313 may be disposed outside the vehicle front windshield 3132, that is, the light receiving module 313 is disposed outside the vehicle, for example, the light receiving module 313 is disposed on the front side of the roof. When the light receiving module 313 is provided outside the vehicle, the light receiving module 313 may be provided in a cross member on an upper side of the front windshield 3132 of the vehicle, for example, integrated in the cross member and configured to receive light in front of the vehicle.
Next, description will be made taking an example in which the light receiving module 313 is provided on the inner side of the vehicle front windshield 3132.
The light receiving module 313 can be detachably mounted on the front windshield 3132 of the vehicle, for example, the light receiving module 313 can be detached separately in a clamping manner, a threaded connection manner and the like, so that the light receiving module 313 can be replaced and maintained conveniently; of course, the light receiving module 313 may be fixed to the front windshield 3132 in a non-detachable manner, and the light receiving module 313 cannot be detached alone.
It should be understood that the vehicle front windshield 3132 of the present embodiment is a glass that can transmit infrared light and visible light.
Alternatively, in some embodiments, the vehicle front windshield 3132 is part of the light receiving module 313, and the vehicle front windshield 3132 cooperates with other structures of the light receiving module 313 to achieve the acquisition of the target image; alternatively, in some embodiments, the light receiving module 313 is disposed independently of the vehicle front windshield 3132, that is, the vehicle front windshield 3132 does not belong to the structure of the light receiving module 313, in the present embodiment, the light receiving module 313 may independently achieve the acquisition of the target image, and the loss of infrared light and visible light through the vehicle front windshield 3132 is small or non-existent.
Referring to fig. 1, the light receiving module 313 may include a housing (not shown) and an image capturing module 3131, wherein the image capturing module 3131 is received in the housing, and the housing is provided with a light transmitting opening facing a front windshield 3132 of the vehicle. The image collection module 3131 of the present embodiment includes a single lens 31311 and an image sensor 31312. In the present embodiment, after the infrared light and the visible light are reflected by the target, the reflected infrared light and the reflected visible light pass through a front windshield 3132 of the vehicle and are incident to the image capturing module 3131 from the light transmitting opening, the infrared light and the visible light are captured by the lens 31311 at the same time, and the infrared light and the visible light are converged onto the image sensor 31312 to obtain an image of the target.
The existing method adopts a set of visible light receiving module to be matched with a visible light source and a car lamp lens module to collect a visible light image of a target, simultaneously adopts a set of infrared light receiving module to be matched with an infrared light source and an infrared lens to collect an infrared light image of the target, and then fuses the visible light image and the infrared light image collected at the same moment to form the target image. The vehicle vision system 300 of this embodiment simultaneously irradiates the target with the infrared light and the visible light, and then simultaneously collects the infrared light and the visible light reflected by the target using the same set of light receiving module 313, so that the target image collected by the vehicle vision system 300 of this embodiment displays both the visible light information and the infrared radiation characteristic information of the target, and this way reduces the time delay and reduces the image distortion.
In addition, in some embodiments, the focal length of the lens 31311 in the image acquisition module 3131 for infrared light and the focal length of the lens 31311 in the image acquisition module 3131 for visible light are equal in size, and in this design, the focal plane offset of visible light and infrared light is eliminated, so that the vehicle vision system 300 can image clearly under the illumination conditions of visible light and infrared light at the same time.
For example, the lens 31311 may be an infrared lens, which may eliminate the focal plane offset of the visible light and the infrared light, so that the visible light and the infrared light are imaged on the same focal plane to obtain a clear image. In addition, the surface of the infrared lens can be coated with multiple layers of films so as to increase the transmittance of infrared light and increase the monitoring distance at night.
Further alternatively, the light receiving module 313 may further include a bracket, and the lens 31311 and the image sensor 31312 in the image collection module 3131 are fixedly connected to the housing through the brackets, respectively. The lens 31311 and the image sensor 31312 in the image capture module 3131 may be fixedly connected to the housing based on the same bracket, saving installation time; of course, the lens 31311 and the image sensor 31312 in the image capturing module 3131 may also be fixedly connected to the housing by different brackets, reducing the weight of the brackets. Wherein, the support can be based on connected modes fixed connection such as buckle, screw thread with the inside wall of shell.
The image sensor 31312 may be a CCD (Charge-coupled Device) image sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor, or may be another type of image sensor.
Further alternatively, the light receiving module 313 may further include a light shield, and the housing is accommodated in the light shield, and the light shield is provided with an opening matched with the light transmitting opening. This embodiment prevents that outside veiling glare from getting into the shell and leading to the precision of the target image of collection to descend through setting up the lens hood. A light shielding layer may be directly disposed on the inner wall of the housing to replace the function of the light shielding cover. Of course, the light receiving module 313 may not be provided with a light shield, thereby reducing the cost.
In order to reduce the weight of the light receiving module 313, the housing, the bracket, the light shield, and the like of the light receiving module 313 are made of light materials, such as plastics.
In addition, the infrared light supplement system in the existing vehicle directly displays the acquired target image on a display platform of vehicles such as a vehicle instrument panel and the like for drivers to distinguish by naked eyes, the final judgment is still made by the drivers, and the distinguishing accuracy is poor. Optionally, the present embodiment recognizes the target image based on machine vision, and outputs the recognition result. For example, in some embodiments, the processor 330 of the vehicle vision system 300 is in communication with the light receiving module 313, the light receiving module 313 sends the target image to the processor 330, and the processor 330 is capable of recognizing the target image and outputting the recognition result. Illustratively, the processor 330 is configured to send the recognition result to a display platform of the vehicle, and the display platform of the vehicle displays the recognition result. For a vehicle driven by a person, the processor 330 of the vehicle vision system 300 may identify the classification of each target in the target image based on machine identification, such as whether the target is a person or an object, so as to warn the driver and improve driving safety.
In other embodiments, the light receiving module 313 sends the target image to a processing platform of the vehicle, so that the processing platform recognizes the target image and outputs the recognition result. In this way, the vehicle vision system 300 does not need to be provided with a processor, reducing hardware costs. For a vehicle driven by a person, the classification of each target in the target image can be recognized by the vehicle processing platform based on a machine recognition mode, such as whether the target is a person or an object, so that a driver is warned, and driving safety is improved.
Wherein, the processing platform can output the identification result through the display platform of the vehicle.
The recognition result can be output in a form of text, graphics or a combination of text and images, or in other forms, such as voice. Additionally, the display platform may be a display screen or dashboard of the vehicle.
Of course, the target image collected by the light receiving module 313 may also be directly displayed on the display platform of the vehicle in the existing manner, and then recognized by the naked eye of the driver for driving guidance.

The vehicle vision system 300 of the embodiment of the invention arranges the infrared light source at the visible light source, so that the infrared light source and the visible light source share the same vehicle lamp lens module, thereby saving the vehicle lamp space, not needing to customize the vehicle lamp specially, and being adaptable to various vehicles; meanwhile, the same set of light receiving module is used for collecting infrared light and visible light, so that the cost is reduced, the target image collected by the light receiving module 313 not only displays the visible light information of the target but also displays the infrared radiation characteristic information of the target, the content of the target image is rich, and the mode of collecting the target image has small delay and small distortion of the target image; based on the machine recognition target image, the recognition result has higher accuracy, thereby effectively guiding the vehicle to run.
