DETAILED DESCRIPTION

[0021] In view of the problem that the infrared fill light system of existing vehicles is expensive, requires a separately designed infrared lens, and is not adaptable for installation, the vehicle vision system of the present application sets the infrared light source at the visible light source, so that the infrared light source and the visible light source share the same headlight lens module, saving headlight space, eliminating the need for specially customized headlights, and can be adapted to a variety of vehicles; at the same time, the same set of light receiving modules is used to collect infrared light and visible light, reducing costs.

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] It should be noted that, in the absence of conflict, the features in the following embodiments and implementations may be combined with each other.

[0024] See also Figure 1 , an embodiment of the present application provides a vehicle vision system, the vehicle vision system 300 may include a first optical system 310 and an infrared light source 320, wherein the first optical system 310 includes a visible light source 311, a headlight lens module 312 and a light receiving module. The infrared light source 320 of this embodiment is arranged at the visible light source 311, and in this embodiment, the infrared light emitted by the infrared light source 320 and the visible light emitted by the visible light source 311 can be simultaneously converged and emitted through the headlight lens module 312 to illuminate the target in front of the vehicle, and the target may include but is not limited to people, obstacles, etc. Further, the infrared light and the visible light are reflected by the target and incident on the light receiving module 313, and converge in the light receiving module 313 to form an image to obtain the target image. The vehicle vision system of the embodiment of the present invention sets the infrared light source 320 at the visible light source 311, so that the infrared light source 320 and the visible light source 311 share the same headlight lens module 312, thereby saving headlight space, eliminating the need for specially customized headlights, and being adaptable to a variety of vehicles; at the same time, the same set of light receiving modules 313 is used to collect infrared light and visible light, thereby reducing costs. The target image collected by the light receiving module 313 displays both the visible light information and the infrared radiation characteristic information of the target. The target image is rich in content, and the method of collecting the target image has low delay and low distortion of the target image.

[0025] The visible light source 311 and the infrared light source 320 can be installed on the same lamp holder or on different lamp holders. When the visible light source 311 and the infrared light source 320 are installed on different lamp holders, the lamp holder for installing the visible light source 311 and the lamp holder for installing the infrared light source 320 need to be arranged side by side.

[0026] The infrared light source 320 is generated by an infrared fill light, and the visible light source 311 is generated by a visible light lamp, which may be a halogen lamp or a xenon lamp. In this embodiment, there is one external fill light and one visible light lamp respectively.

[0027] The visible light lamp and the headlight lens module 312 of this embodiment cooperate to realize two functions of the first optical system 310, namely, the low beam function and the high beam function. At the same time, one of the low beam function and the high beam function is turned on and the other is turned off.

[0028] In this embodiment, the headlight lens module 312 at least includes a focusing lens. For example, in one embodiment, the headlight lens module 312 includes a focusing cup and a focusing lens, wherein the focusing cup is provided with a groove, which is roughly in the shape of a "bowl", the visible light source 311 and the infrared light source 320 are provided in the groove, and the focusing lens is installed at the opening of the focusing cup and faces the visible light source 311 and the infrared light source 320. The focusing cup can focus the visible light emitted by the visible light source 311 and the infrared light emitted by the infrared light source 320 into a beam of parallel mixed light, and then diverge into fan-shaped light through the focusing lens.

[0029] Among them, the focusing lens can be a single-beam lens or a double-beam lens, and the type of focusing lens is specifically determined by the structure of the vehicle headlight. The single-beam lens includes a low-beam lens and a high-beam lens, which correspond to low beam and high beam respectively. The double-beam lens is a lens that shares the same lens for high beam and low beam, which can be used as a change similar to the conversion between high and low beams. Specifically, the switching between high and low beams is achieved through the shading sheet in the double-beam lens. For example, when the shading sheet is closed, the visible light obtains low beam after passing through the double-beam lens; when the shading sheet is opened, the visible light obtains high beam after passing through the double-beam lens. The opening and closing of the shading sheet can be operated by an electromagnetic mechanism.

[0030] It should be understood that the vehicle light lens module 312 of this embodiment may also be an existing vehicle light lens module.

[0031] The infrared light source 320 can 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 automatically. Figure 2, the vehicle vision system 300 also 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. Among them, the ambient light sensor 340 is used to detect the brightness of the ambient light. In some embodiments, the processor 330 turns on the infrared light source 320 when the brightness of the ambient light is less than or equal to the preset brightness threshold. In some embodiments, when the brightness of the ambient light is less than or equal to the preset brightness threshold, the processor 330 turns on the visible light source 311 in addition to turning on the infrared light source 320. Exemplarily, when the vehicle is driving at night or in other low-light environments, the ambient light intensity detected by the ambient light sensor 340 is less than or equal to the first preset brightness threshold. 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 ambient light intensity 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 driving in a very poor light environment such as a highway or a country road, the infrared fill light and the high beam function are turned on at the same time. By increasing the illumination intensity through the high beam function, long-distance detection under weak ambient light can be achieved, ensuring driving safety in a low light environment such as a highway or a country road; when the ambient light intensity 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 low beam function to be turned on. For example, when the vehicle is driving in a low light environment such as an urban road, the low beam function can meet the requirements of safe driving of the vehicle. The first preset brightness threshold and the second preset brightness threshold can be set as needed. In addition, the installation position of the ambient light sensor 340 can be selected as needed. For example, the ambient light sensor 340 is arranged at the front side of the vehicle to better detect the ambient light brightness at the front side of the vehicle. Of course, the ambient light sensor 340 can also be arranged in other areas of the vehicle, for example, the ambient light sensor 340 is arranged at the front side of the roof, such as integrated in the crossbeam at the front side of the roof. The embodiment of the present invention does not specifically limit the type of the ambient light sensor 340, and any sensor that can detect the ambient light brightness is within the protection scope of the present invention.

[0032] In some other embodiments, the infrared light source 320 and the visible light source 311 are manually controlled to be turned on. For example, see Figure 3 The vehicle vision system 300 further includes two control switches 350, one of which is used to control the on / off of the infrared light source 320, and the other is used to control the on / off of the visible light source. Figure 3As shown, the visible light source 311 is turned on and off by the first control switch 351, and the infrared light source 320 is turned on and off by the second control switch 352. Of course, in other embodiments, the infrared light source and the visible light source can also be turned on at the same time by the same control switch. For example, the infrared fill light and the low beam function are turned on at the same time by the same control switch, and the infrared fill light and the high beam function can also be turned on at the same time by the same control switch. Among them, the type of control switch can be selected as needed, and the control switch can be a button, a knob, etc. The control switch can be set at a position that is easy for the vehicle driver to operate. For example, a button for the infrared light source 320 can be added to the existing headlight control module, and the button is used to control the opening and closing of the infrared light source 320 separately. In addition, the existing headlight control module also has a knob that can control the opening and closing of the high beam function and the low beam function. When the knob is rotated to the trigger 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 trigger angle corresponding to the high beam function, the high beam function is turned on and the low beam function is turned off. For another example, with respect to an existing knob that controls the on and off of the high beam function and the low beam function by rotating to different angles, when the knob is rotated to a trigger angle corresponding to the low beam function and an angle corresponding to the high beam function, the infrared light source 320 is simultaneously triggered to turn on, that is, when the knob is rotated to a trigger angle corresponding to the low beam function, the low beam function and the infrared light source 320 are simultaneously turned on; when the knob is rotated to a trigger angle corresponding to the high beam function, the high beam function and the infrared light source 320 are simultaneously turned on.

[0033] The light receiving module 313 of this embodiment can be arranged on the inner side of the front windshield 3132 of the vehicle, that is, the light receiving module 313 is arranged inside the vehicle, which effectively prevents the light receiving module 313 from being lost, and effectively prevents the light receiving module 313 from being worn by the external environment, thereby extending the service life of the light receiving module 313; of course, the light receiving module 313 can also be arranged on the outer side of the front windshield 3132 of the vehicle, that is, the light receiving module 313 is arranged outside the vehicle, for example, the light receiving module 313 is placed on the front side of the roof. When the light receiving module 313 is arranged outside the vehicle, the light receiving module 313 can be arranged in the crossbeam on the upper side of the front windshield 3132 of the vehicle, for example, integrated in the crossbeam and used to receive light in front of the vehicle.

[0034] The following description will be made by taking the case where the light receiving module 313 is disposed on the inner side of the front windshield 3132 of the vehicle as an example.

[0035] The optical receiving module 313 can be installed on the vehicle's front windshield 3132 in a detachable manner, such as by snap-on, threaded connection, etc., the optical receiving module 313 can be removed separately, which is convenient for replacement and maintenance of the optical receiving module 313; of course, the optical receiving module 313 can also be fixed on the vehicle's front windshield 3132 in a non-detachable manner, and the optical receiving module 313 cannot be removed separately.

[0036] It should be understood that the vehicle front windshield 3132 of this embodiment is a glass that can transmit infrared light and visible light.

[0037] Optionally, in some embodiments, the vehicle front windshield 3132 is a part of the light receiving module 313, and the vehicle front windshield 3132 cooperates with other structures of the light receiving module 313 to realize the acquisition of the target image; optionally, in some embodiments, the light receiving module 313 is independently provided from 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 this embodiment, the light receiving module 313 can independently realize the acquisition of the target image, and the loss of infrared light and visible light passing through the vehicle front windshield 3132 is small or there is no loss.

[0038] Please combine Figure 1 , the light receiving module 313 may include a housing (not shown) and an image acquisition module 3131, wherein the image acquisition module 3131 is housed in the housing, and the housing is provided with a light-transmitting port, which is arranged toward the front windshield 3132 of the vehicle. The image acquisition module 3131 of this embodiment includes a single lens 31311 and an image sensor 31312. In this embodiment, after the infrared light and the visible light are reflected by the target, they are incident on the image acquisition module 3131 from the light-transmitting port after passing through the front windshield 3132 of the vehicle, and the infrared light and the visible light are simultaneously collected by the lens 31311, and the infrared light and the visible light are converged onto the image sensor 31312 to obtain the target image by imaging.

[0039] In the prior art, a set of visible light receiving modules is used in conjunction with a visible light source and a headlight lens module to collect visible light images of a target, and a set of infrared light receiving modules is used in conjunction with an infrared light source and an infrared lens to collect infrared light images of a target, and then the visible light image and infrared light image collected at the same time are fused to form a target image. The target image obtained in this way not only has a delay, but also inevitably has image distortion. Since the vehicle vision system 300 of this embodiment uses infrared light and visible light to illuminate the target at the same time, and then uses the same set of light receiving modules 313 to simultaneously collect infrared light and visible light reflected back by the target, the target image collected by the vehicle vision system 300 of this embodiment displays both the visible light information of the target and the infrared radiation characteristic information of the target. This method reduces delay and image distortion.

[0040] In addition, in some embodiments, the focal length of the lens 31311 in the image acquisition module 3131 for infrared light is equal to the focal length of the lens 31311 in the image acquisition module 3131 for visible light. With this design, the focal plane offset of visible light and infrared light is eliminated, so that the vehicle vision system 300 can simultaneously form clear images under visible light and infrared light lighting conditions.

[0041] For example, the lens 31311 can be an infrared lens, which can eliminate the focal plane offset of visible light and infrared light, so that visible light and infrared light are imaged on the same focal plane to obtain a clear image. In addition, the surface of the infrared lens can also be multi-layer coated to increase the transmittance of infrared light and increase the monitoring distance at night.

[0042] Further optionally, the light receiving module 313 may also include a bracket, and the lens 31311 and the image sensor 31312 in the image acquisition module 3131 are fixedly connected to the housing through the bracket. The lens 31311 and the image sensor 31312 in the image acquisition module 3131 can 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 acquisition module 3131 can also be fixedly connected to the housing by different brackets to reduce the weight of the bracket. Among them, the bracket and the inner side wall of the housing can be fixedly connected based on a connection method such as a buckle or a thread.

[0043] 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 other types of image sensors.

[0044] Further optionally, the light receiving module 313 may also include a light shield, the housing is accommodated in the light shield, and the light shield is provided with an opening that matches the light transmission port. In this embodiment, by providing a light shield, external stray light is prevented from entering the housing, resulting in a decrease in the accuracy of the collected target image. A light shielding layer may also be directly provided on the inner side wall of the housing to replace the function of the light shield. Of course, the light receiving module 313 may also not be provided with a light shield to reduce costs.

[0045] In order to reduce the weight of the light receiving module 313 , the housing, bracket, light shield, etc. of the light receiving module 313 are made of lighter materials, such as plastic.

[0046] In addition, the infrared fill light system in the existing vehicle directly displays the collected target image on the vehicle's display platform such as the vehicle dashboard for the driver to distinguish with the naked eye. The final judgment is still made by the driver, and the accuracy of the distinction is poor. Optionally, this embodiment recognizes the target image based on machine vision and outputs the recognition result. For example, in some of the embodiments, the processor 330 of the vehicle vision system 300 communicates with the light receiving module 313, and the light receiving module 313 sends the target image to the processor 330. The processor 330 can recognize the target image and output the recognition result. Exemplarily, the processor 330 is used to send the recognition result to the display platform of the vehicle, and the recognition result is displayed by the display platform of the vehicle. For manned vehicles, the processor 330 of the vehicle vision system 300 can identify the classification of each target in the target image based on machine recognition, such as whether the target is a person or an object, thereby warning the driver and improving driving safety.

[0047] In some other embodiments, the light receiving module 313 sends the target image to the 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 equipped with a processor, which reduces the hardware cost. For manned vehicles, the processing platform of the vehicle can identify the classification of each target in the target image based on machine recognition, such as whether the target is a person or an object, thereby warning the driver and improving driving safety.

[0048] Among them, the processing platform can output the recognition results through the vehicle's display platform.

[0049] The recognition result can be output in the form of text, graphics, or a combination of text and images, or in other ways, such as voice. In addition, the display platform can be a display screen or dashboard of the vehicle.

[0050] Of course, the existing method can also be adopted to directly display the target image collected by the light receiving module 313 on the display platform of the vehicle, and the driver can distinguish it with naked eyes to provide driving guidance.

[0051] See also Figure 1 and Figure 4 An embodiment of the present application also provides a vehicle, which may include a processing platform 100, a display platform 200 and the vehicle vision system 300 of the above embodiment, wherein the processing platform 100 is electrically connected to the display platform 200 and the vehicle vision system 300 respectively.

The vehicle vision system 300 of the embodiment of the present invention sets the infrared light source at the visible light source, so that the infrared light source and the visible light source share the same headlight lens module, saving headlight space, eliminating the need for specially customized headlights, and being adaptable to a variety of vehicles; at the same time, the same set of light receiving modules is used to collect infrared light and visible light, reducing costs. The target image collected by the light receiving module 313 displays both the visible light information of the target and the infrared radiation characteristic information of the target. The target image is rich in content, and the method of collecting the target image has low delay and low distortion of the target image; based on machine recognition of the target image, the recognition result is more accurate, thereby effectively guiding vehicle driving.
