Abstract: Disclosed herein is a method for mitigating glare from a windshield of an automobile. Plurality of images, captured from plurality of image capturing devices placed at predefined locations of automobile, are collected. Various image processing techniques are applied on the plurality of collected images to identify line of sight of driver of the automobile, presence of glare on the windshield and position of glare. A free floating opaque matter placed within the windshield is moved to the position of glare on windshield, thereby preventing the glare from affecting the driver. Movement of opaque matter on to the position of the glare is achieved by varying electrostatic potential to be applied across metal frame encircling the windshield. The windshield disclosed hereinabove is capable of adaptively positioning the opaque matter over the position of the glare without requiring any intervention from the driver, thereby facilitating in a smooth drive of the automobile. FIG. 1A
Claims:WE CLAIM:
1. A method for mitigating glare from a windshield (101) of an automobile, the method comprising:
receiving, by a glare mitigation system (201), a plurality of images (207) from each of plurality of image capturing devices (103) placed at predefined locations of an automobile;
determining, by the glare mitigation system (201), line of sight (107) of a driver of the automobile based on one of the plurality of images (207);
determining, by the glare mitigation system (201), position of a glare based on location of each of the plurality of image capturing devices (103), resolution of each of the plurality of images (207), and reference point of windshield (105) of the automobile upon determining the line of sight (107) of the driver; and
positioning adaptively, by the glare mitigation system (201), a free floating opaque matter (111), present within the windshield (101), over the position of the glare for mitigating the glare from the windshield (101).
2. The method as claimed in claim 1, wherein presence of the glare on the windshield (101) is detected based on another of the plurality of images (207).
3. The method as claimed in claim 2, wherein the glare is verified to be present along line of sight (107) of driver when intensity of light in the another of the plurality of images (207) is higher than a threshold intensity value (209).
4. The method as claimed in claim 3, wherein the threshold intensity value (209) is dynamically determined based on ambient light intensity around the automobile.
5. The method as claimed in claim 1, wherein the determining the position of the glare on the windshield (101) comprises:
identifying one or more image blocks, having predetermined block size, in another of the plurality of images (207);
comparing intensity of light in each of the one or more image blocks with the intensity of light in each of other image blocks to identify an image block having highest intensity of light;
identifying position of the image block having the highest intensity of light based on the block size of the image block and resolution of the another of the plurality of images (207); and
determining the position of the glare on the windshield (101) based on the position of the image block with respect to the reference point of the windshield (105) and the location of each of the plurality of image capturing devices (103).
6. The method as claimed in claim 1, wherein positioning the free floating opaque matter (111) over the position of the glare comprises varying electrostatic potential across a metal (109) frame enclosing the windshield (101), thereby causing movement of the free floating opaque matter (111) within the windshield (101).
7. The method as claimed in claim 6, wherein density, shape and size of the free floating opaque matter (111), to be positioned over the position of the glare, is determined based on the intensity of light, size and shape of the glare.
8. A windshield (101) comprising:
a first layer of a solid transparent material;
a second layer of the solid transparent material, placed adjacent to the first layer, wherein a region between the first layer and the second layer is provided with a liquid transparent material and a free floating opaque matter (111), wherein edges of the first layer and the second layer are enclosed within a metal frame (109); and
the metal frame (109) is connectable to an electrostatic power source (113) in the automobile.
9. The windshield (101) as claimed in claim 8 is associated with plurality of image capturing devices (103), placed at predefined locations on at least one of the first layer or the second layer of the windshield (101), to capture plurality of images (207).
10. The windshield (101) as claimed in claim 8 is connected to a control unit (225), associated with the electrostatic power source (113), to control electrostatic potential to be applied across the metal frame (109).
11. The windshield (101) as claimed in claim 8 is connected to a glare mitigation system (201), wherein the glare mitigation system (201) adaptively positions the free floating opaque matter (111) over position of glare on the windshield (101).
12. The windshield (101) as claimed in claim 11, wherein the free floating opaque matter (111) is positioned over the position of the glare by varying electrostatic potential, generated by electrostatic power source (113), across metal frame (109) enclosing the windshield (101).
