Description

Visual enhancement system and device thereof

The present invention relates to a vision enhancement system and apparatus therefor.

Usually, in low visibility situations, such as at night or on a rainy day, the driver needs to rely on the headlights of the vehicle to illuminate the road ahead.

Such headlamps typically produce many different types of illumination, with the most common being low beam and high beam. However, as shown in Fig. 1, the conventional illumination can provide a visibility range of up to 50 meters. However, if the vehicle is driving at a high speed on the highway at night, there will not be enough for the driver. The time to perform an emergency stop action. As a result, the Transportation Authority in many countries has severely restricted commercial vehicles to a lower vehicle speed limit.

Many people have considered the upper speed range as the cause of such problems, but high-intensity lights have been proposed as an alternative. Although such a luminaire can increase the range of illumination, it may obscure the sight of other passers-by. In this regard, regulations also prohibit the use of such high-intensity lights.

Subsequently, the car night vision system was introduced to reinforce the headlights, and the car night vision system can increase the line of sight, especially at night, in bad weather, etc., far exceeding the limits of the headlamps. The car night vision system, especially the existing system, is composed of an infrared (IR) light source and an infrared camera, red The external light source is used to illuminate the road ahead, because infrared light is invisible to humans, and the infrared camera is used to receive infrared light so that the driver can obtain a distant range of visual images. In addition, with regard to invisible infrared light, infrared light does not cause wild animals to be alarmed, thus reducing the number of road-kills that are commonly found on the roads in cities.

While such automotive night vision systems are clearly capable of assisting the driver in visibility of the road, current systems have some disadvantages, such as the complexity of such systems and the high cost of installation. Therefore, these systems are more commonly installed only in high-priced luxury vehicles. In addition, these systems usually operate only in a short range, such as 150 to 200 meters, which is not enough for practical use standards. Furthermore, it is very difficult to rewrite such a system to operate smoothly in fog, rain or snow. Another disadvantage is that such systems are very common with flare issues, and it has been observed that such systems are difficult to avoid halos from any intensity source, let alone any general illumination.

Furthermore, the longer the wavelength of conventional electromagnetic radiation, such as visible light and infrared light (IR), the less energy there is. It is also known that the intensity of the light emitted by the point source decreases as the distance increases. This is due to the further the distance from the source of the emission, the greater the surface area illuminated by the source, since the source propagates in a divergent manner with distance. In this regard, since infrared light is a longer wavelength light source, it is more difficult for infrared light to propagate to a farther range.

Similarly, as the wavelength of light increases, the refractive index of light decreases. It is known that the light sources of different wavelengths behave differently after passing through the lens. More specifically, since infrared light generally has a longer wavelength, that is, has a relatively lower refractive index, it means that it is more difficult to focus the infrared light, which is further caused by an increase in wavelength, an optical system such as a lens. The fact that the focal length will increase will also be supported. Since the focal length is related to the effect of the optical system focusing the light, this means that for short-wavelength infrared light, the optical system is often more difficult to focus on.

As can be seen from the above, a visual augmentation system can simplify the complexity of the existing car night vision system, reduce the cost of the existing system, increase the line of sight to 200 meters or more, and solve the problem of low visibility due to rain, fog, or night. /Limited issues, providing anti-halation, and the ability to add optical systems to focus on infrared light is a must.

Accordingly, a visual enhancement system and apparatus therefor are provided.

According to an aspect of the invention, a visual enhancement system includes a plurality of illumination units, an infrared (IR) optical imaging unit for capturing an image in a first direction, and a display unit for displaying an image.

Each illumination unit has a complex infrared source and a plurality of infrared focusing lenses, a plurality of infrared sources for emitting infrared beams, and a plurality of infrared focusing lenses for focusing the infrared beams in a first direction.

The infrared focusing lens includes a bottom surface, a side surface, and a top surface, red The external focusing lens is divided into a plurality of types; the infrared beam focused by the infrared focusing lens contains a different distance range and a range of regions depending on the type of the infrared focusing lens, and the wavelength range of the infrared beam is negatively correlated with the region range. And vice versa.

According to another aspect of the present invention, a visual enhancement device includes a plurality of illumination units, an infrared vision camera unit for capturing an image in a first direction, and a display unit for displaying an image.

Each illumination unit has a complex infrared source and a plurality of infrared focusing lenses, a plurality of infrared sources for emitting infrared beams, and a plurality of infrared focusing lenses for focusing the infrared beams in a first direction.

The infrared focusing lens comprises a bottom surface, a side surface, and a top surface, and the infrared focusing lens is divided into a plurality of types; the infrared beam focused by the infrared focusing lens comprises a different distance range and a region range, which is determined by infrared focusing. The type of lens, and the distance range of the infrared beam is inversely related to the area range, and vice versa.

It is a further object of the present invention to provide a visual enhancement system and apparatus thereof that address the problem of low/limited visibility due to rain, fog, or nighttime.

A further object of the present invention is to provide an infrared focusing lens having a specific shape and function capable of solving a low refractive index caused by relatively long wavelength infrared light, and focusing the infrared light to a longer range, such as 200 Up to 500 meters, the problem. Since the infrared focusing lens can not only focus on the infrared light, but also focus the infrared light to the above distance, the divergence of the infrared light with the distance can be reduced, thereby reducing the decrease of the infrared light with the distance intensity.

A final object of the present invention is to provide a visual enhancement system and apparatus therefor that includes an antihalation element that is mounted in a CCD camera (Charge-Couple Device camera). The anti-halo element is used to prevent or reduce the halo problem of the image, and can also be used to confirm that the anti-halo element and the camera still operate normally when a strong light source directly illuminates the camera.

The novel features and elements of the present invention are set forth in the Detailed Description of the Drawings. The scope and variety of variations of the invention can be varied.

The present invention is directed to a visual enhancement system 100 and apparatus 1000 thereof, and a preferred embodiment of the visual enhancement system 100 of the present invention will be described hereinafter with reference to the drawings, but it is understood that the preferred embodiments are not intended to limit the invention. The drawings are only intended to illustrate the invention, and any modifications and adaptations may be made without departing from the spirit of the invention.

Alternatively, the visual enhancement system 100 of the present invention and its apparatus 1000 can be considered a car night vision system.

Referring to FIG. 2, the visual enhancement system 100 and apparatus 1000 thereof of the present invention include an infrared vision camera unit 10, a plurality of illumination units 20, and a display unit 30.

Referring to FIG. 5, the infrared vision camera unit 10 includes a camera, which may be a modified CCD camera (modified Charge-Couple Device camera), or a camera, such as a rear view camera. For the camera. In addition, the resolution of the rear view camera is modifiable, such as the screen refresh rate is basically set to a delay of 0.5 seconds.

An antihalation unit is combined with a camera, and the antihalation unit is used to prevent or reduce the halo problem of the image, and is selectively mounted with an antihalation processing element for solving the existing infrared camera. The flash blindness ensures that the anti-halation treatment component is still functioning when a strong light source is directly incident on the camera.

Referring to FIG. 6, optionally, an electrochromic processing element (not shown) may also be disposed in the visual enhancement system 100 and the device 1000 thereof. The electrochromic element includes an electrochromic film 600 fixed to the camera. A rear or front side of an outer lens, an electrochromic sensing element (not shown), and an electrochromic processing element (not shown) are coupled to the electrochromic film 600 and the electrochromic sensing element. The electrochromic sensing element is used to blacken the electrochromic film 600 when a strong light source is detected to be directed toward the camera or the ambient light source is below a predetermined level. The electrochromic processing element also causes the electrochromic film 600 to become transparent when the electrochromic sensing element detects that no strong light source or ambient light source is above a predetermined level.

In addition, the size of the CCD camera is also significantly reduced to be able to be mounted just in a selected mounting area. As shown in FIG. 6, the infrared vision camera unit 10 further has an opening 230 for connecting the input of the power cable.

Referring to FIG. 4 and FIGS. 7 to 10, each illumination unit 20 has a plurality of infrared light sources 60 and a plurality of infrared focus lenses 40, and the infrared focus lens 40 is Mounted to a plurality of individual components 70, the intensity of the infrared source 60 is adjustable. The plurality of illumination units 20 further includes an illumination processing component for controlling the intensity of the plurality of infrared light sources 60, wherein the greater the intensity of the plurality of infrared light sources 60, the longer the range of distances that can be illuminated, and the decrease in intensity is related to the infrared beam distance range. of.

Optionally, each infrared source 60 is an infrared light emitting diode (LED) rather than a conventional infrared light bulb. The use of infrared light-emitting diodes is due to the ability of infrared light-emitting diodes to overcome low visibility, especially when it is raining, fogging or at night. In addition, the complex infrared light emitting diodes are capable of emitting infrared beams of uniform intensity. Due to the dispersion characteristics of the light of the infrared light emitting diode, the infrared focusing lens 40 is used to focus the infrared light beam, especially on the road.

Referring to FIGS. 7-10, the infrared focusing lens 40 includes a conical structure having a bottom surface 41, a side surface 43, and a top surface 45. A platform 820 is coupled to the bottom surface 41. The side surface 43 is outwardly curved in a direction perpendicular to its surface, and the top surface 45 includes a top surface slot 830 having an inner bottom surface 850. Optionally, the side surface 43 can include a plurality of sides (not shown).

The top surface slot 830 may have a cylindrical shape. The inner bottom surface 850 includes a spherical top end 860. The plurality of infrared light sources are fixed in front of the spherical tip 860.

Specifically, the infrared focusing lens 40 is divided into a plurality of types. Referring to FIG. 3, the infrared focusing lens 40 is used to focus to different distances depending on the type. Infrared beams from range and area, in general, the range of distance is related to the distance from which the target is still visible.

The infrared focusing lens 40 changes a range of distances and a range of infrared beams depending on the type, such as an infrared beam from a short range to a long distance, and a range from a large area to a small area. The distance range of the infrared beam is inversely related to the area range. In other words, for a lens type that can focus the infrared beam to a relatively long range of distances, the range of the infrared beam is relatively small. On the other hand, for a lens type that can focus the infrared beam to a relatively short range of distances, the range of the infrared beam is relatively large.

The complex infrared focusing lens 40 is divided into a first type of infrared focusing lens, a second type of infrared focusing lens, and a third type of infrared focusing lens. Although the plurality of infrared focusing lenses 40 are classified into three types, such as a first type of infrared focusing lens, a second type of infrared focusing lens, and a third type of infrared focusing lens, the plurality of infrared focusing lenses 40 may include at least two types of infrared rays. Focusing lens 40, wherein each type selectively produces infrared beams of different or the same range of distances and regions.

Referring to FIG. 7, the first focusing lens 42 includes a bottom surface groove 840 formed at a center of the bottom surface 41 and on the same vertical axis as the spherical tip 860, the vertical axis being perpendicular to the center of the spherical tip. Additionally, referring to Figures 8 and 9, the platform 820 of the second focusing lens 46 includes a matte outer surface 870. As shown in Figure 8, the matte outer surface 870 can be a flat surface 910, as shown in Figure 9, frosted The outer surface 870 can be an inner curved surface 920 having a center of curvature on the same vertical axis as the spherical top end 860, the vertical axis being perpendicular to the center of the spherical tip.

Referring to FIG. 10, the platform 820 of the third focusing lens 48 can include a textured outer surface 880, the textured outer surface 880 includes an inner curved surface 920, and the center of curvature of the inner curved surface 920 is the same as the spherical top end 860. On the vertical axis, the vertical axis is perpendicular to the center of the spherical tip.

Referring again to FIG. 3, in all types of infrared focusing lenses 40, the first focusing lens 42 is used to focus the infrared beam to a region having a lower range of the longest distance and a minimum region in the region of the sacrificial infrared radiation. The infrared beam. The number of infrared light emitting diodes using the first type of infrared focusing lens 40 is in the range of 4 to 15. Specifically, about 6-12 infrared focusing lenses 40 of this type are used with each system 100 or device 1000. This type of infrared focusing lens enables a range of distances of up to 200 meters or more, as shown in the example of Figure 3. The first type also enables the region of the infrared beam to be moved radially between 4 and 8 degrees from the axis of travel of the infrared beam, or more accurately 6 degrees.

The second focusing lens 46 is an infrared beam that is used to focus the infrared beam to a relatively short range of distances and a larger area. Specifically, since some areas are still the first type of infrared focusing lens 40, which cannot control the area where the infrared beam is divergent, to solve this problem, the second type of infrared focusing lens is set. The range of regions used to expand the illumination of the infrared beam is selected to selectively cover the extent that the first type of infrared focusing lens does not cover or partially cover one of the first regions. The number of infrared light-emitting diodes using the second type of infrared focusing lens is in the range of 2 to 10. Alternatively, however, each system 100 or device 1000 will use exactly 4-8 second type infrared focusing lenses. Alternatively, the second type of infrared focusing lens can achieve a distance ranging from 50 meters to 100 meters, as shown in FIG. The second type also enables the region of the infrared beam to be moved radially between 10 and 14 degrees from the axis of travel of the infrared beam, or more precisely 12 degrees.

The third focusing lens 48 is adapted to focus the infrared beam to an infrared beam having a range of regions that are shorter than the shortest distance. The third type of infrared focusing lens is also more suitable for further increasing the range of the infrared beam illumination until it covers the extent that the first type and the second type of infrared focusing lens do not cover or partially cover a second area. The third type of infrared focusing lens can also be used as an ambient light source. This is because this type is most suitable for illuminating areas that are not covered or partially covered by the first and second types of infrared focusing lenses in front of the vehicle 410. The number of infrared light-emitting diodes using the third type of infrared focusing lens is in the range of 1 to 6. Optionally, each system 100 or device 1000 will have exactly 2-4 infrared illuminating diodes utilizing a third type of infrared focusing lens. The third type provides an infrared beam of the largest extent, substantially between 20 and 40 degrees of radial movement from the axis of travel of the infrared beam, or more precisely 30 degrees.

The first type of infrared focusing lens, the second type of infrared focusing lens, and the third type of infrared focusing lens are substantially 1:2:3, and the third type of infrared focusing lens is selectively capable of illuminating from 0 to 50 meters. The range of distance is shown in the example of FIG. Further, the infrared focusing lens 40 may be made of plastic, acrylic, or a combination of both.

Referring to Figure 4, the infrared illuminating diode and infrared focusing lens 40 are mounted to a plurality of individual components 70, which, for example, as shown in Figure 4, are arranged on the front side 125 of the lighting unit 20. Optionally, the plurality of independent elements 70 may be arranged adjacent to each other in a plurality of rows, and arranged along a long side of the illumination unit 20 as a single or a plurality of columns, or alternatively, the plurality of independent elements 70 may be arranged in a straight line (as shown in the figure). 4), or obliquely arranged in the direction of the line (not shown). Alternatively, the plurality of individual elements 70 may be arranged such that the distance of the plurality of individual elements 70 to focus the infrared beam in accordance with the lens type ranges from near to far, and the corresponding area ranges from wide to narrow, along the illumination unit 20 Change in the length direction, width direction, or a tilt direction.

Referring next to FIG. 2, for the display unit 30, a high definition liquid crystal display (LCD) is selectively used, which may range in size from 4.3 inches to 7 inches.

In addition, the visual enhancement system 100 and its apparatus 1000 further include an ambient light source sensing component 50 for activating the plurality of illumination units 20 when the luminance value of the ambient light source is reduced to a predetermined level. And optionally, the plurality of lighting units 20 are turned off when the brightness value of the ambient light source is increased to a predetermined level. As shown in FIG. 4, the ambient light source sensing element 50 can be selectively secured to one side of the front side 125 of the illumination unit 20.

The plurality of lighting units 20 further includes a cooling unit for cooling the plurality of lighting units 20. Optionally, the cooling unit comprises at least one heat sink. The heat sink is mounted to enable the heat generated by the plurality of infrared light sources 60 to be effectively dissipated. To effectively transfer the heat of the complex infrared source 60, the heat sink is mounted behind a plurality of individual components 70. Alternatively, the thickness of the heat sink can be varied.

Alternatively, at least one fan 90, in particular an ultra-quiet fan, may be mounted on the plurality of lighting units 20. For example, as shown in FIG. 4, the fan 90 is mounted on the rear side 115 of the lighting unit 20 to effectively cool the lighting unit 20. In addition, the fan 90 can also be fixed to the side (135 or 145), the upper side 155, the bottom 165, or the front side 125 of the lighting unit 20.

The lighting unit 20 further includes a plurality of through holes 220 formed on the side 135 or 145 thereof. The plurality of through holes 220 provided herein allow the heat guided by the operating fan 90 to flow out of the plurality of through holes 220 instead of being accumulated in the lighting unit 20.

However, the size of the fan 90 on the front side 125 needs to be reduced to accommodate the individual elements 70 or to be received in the through holes 220 on the side (135 or 145) where the plurality of through holes 220 are located. With the installation of the fan 90, the number or thickness of the heat sink can be further reduced, thereby further reducing the lighting unit 20 size.

Referring to FIGS. 4 and 5, the lighting unit 20 may not include a fan 90 and a plurality of through holes 220. If this is the case, the lighting unit 20 optionally includes at least one heat sink 80. The mounted heat sink 80 can have external fins 82, pins, or any other form to increase the surface area such that heat release is outwardly diffused by the rear side 115 of the lighting unit 20.

Therefore, the housing of the lighting unit 20 can be made of a heat resistant plastic material or an aluminum alloy such as aluminum alloy 6111. In addition, in fact, this material is also an easily available material that can further reduce costs.

Since the plurality of infrared light sources 60 generate heat, in order to prevent overheating, or to prevent the worst case, that is, the lighting unit 20 or the internal material is melted, the cooling unit includes a fan 90, a casing, and a heat sink to solve the heat dissipation problem. .

Next, the plurality of illumination units 20 further includes a thermal sensing component for sensing the heat in the plurality of illumination units 20. The thermal sensing element is connected to a cooling unit, in particular a fan 90. The thermal sensing element is further configured to activate the cooling unit when the heat is increased to a predetermined level, and selectively to close the cooling unit when the heat is reduced to a predetermined level. Alternatively, the thermal sensing element can also be used to turn off the plurality of illumination units 20 when the heat reaches a predetermined maximum level to prevent overheating, or to prevent a worst-case condition, such that the illumination unit 20 or the interior material melts.

Optionally, the visual enhancement system 100 and its apparatus 1000 are expected to be safe Mounted within the interior 310 of the vehicle 410. The plurality of lighting units 20 are sized to facilitate carrying and easy mounting of each lighting unit 20 to the interior 310 or exterior of the vehicle 410. Also optionally, the display unit 30 is sized to enable the display unit 30 to be mounted inside the vehicle 410.

The plurality of lighting units 20 further includes a first lighting unit and a second lighting unit. Optionally, the first lighting unit 21 is placed on the upper left of one of the windshields of the vehicle 410, and the second lighting unit 22 is placed on the upper right of the windshield of the vehicle 410. Referring to FIGS. 2 and 4, the plurality of through holes 220 are formed on the side (135 or 145) of each of the illumination units 20 such that the plurality of through holes 220 of each of the illumination units 20 are always individually directed toward the rear view mirror 330. Furthermore, since the size of the lighting unit 20 in which the fan 90 is mounted is much smaller, the lighting unit 20 mounted above does not block the lower sun visor. Still relating to the illumination unit 20, when the plurality of individual elements 70 are arranged in a range from short to long depending on the distance of the infrared beam, and the area ranges from wide to small in a stepwise manner (from left to right, or from right to left), The individual elements 70 of the infrared beam having the longest distance range and the smallest area range should be located closest to the mirror 330, as shown in FIG.

Additionally, the camera is selectively located behind one of the rearview mirrors 330 of the vehicle 410. The display unit 30 is selectively located in front of the driver.

Referring to Figure 2, since the visual enhancement system 100 and its apparatus 1000 are intended to be mounted inside the vehicle 410, it is easier to enter the infrared camera lens relative to the infrared beam of the windshield. If this situation continues, the camera will face To the flare problem. Thus, the camera is selectively positioned behind the plurality of illumination units (21 and 22) such that no infrared beam can directly enter the lens of the camera to reduce the halo effect of the image.

Optionally, power is supplied to the visual enhancement system 100 or device 1000 through a power cable in the vehicle 410. The visual augmentation system 100 or device 1000 uses existing power cables in the vehicle instead of providing power from itself, such as using batteries, to further reduce the size of the plurality of lighting units 20 such that the plurality of lighting units 20 are less bulky and user friendly. To this end, the plurality of lighting units 20 have a plurality of openings 230 disposed on their upper or bottom side for input of a power cable, as shown in FIG. Moreover, the ambient light source sensing element 50 can be selectively affixed only to a camera having a relatively stable power source for the visual enhancement system 100 or device 1000.

Also optionally, the maximum distance of visibility of the visual enhancement system 100 or device 1000 ranges from 200 meters to 500 meters.

Thus, the visual enhancement system 100 or device 1000 selectively does not provide an obstacle detection system. This is because such an obstacle detection system is an additional function and based on the performance of the visual augmentation system 100 or the device 1000, when it detects any obstacles on the road, such as animals, crossing the road (including any pedestrian crossing the road) ), stone, etc., visual augmentation system 100 or device 1000 is sufficient to assist the driver. Moreover, installing such an obstacle detection system inevitably adds to the cost of the visual enhancement system 100 or device 1000.

Further, alternatively, as a safety measure for protecting the visual enhancement system 100 or the device 1000, a fuse box may be installed in each of the illumination units 20, the infrared vision camera unit 10 such as a camera, and the display unit 30.

The visual augmentation system 100 or device 1000 can also typically be activated during the day.

The technical contents of the present invention have been disclosed in the above preferred embodiments, and are not intended to limit the present invention. Any modifications and refinements made by those skilled in the art without departing from the spirit of the present invention are encompassed by the present invention.
