Systems and arrangements for providing situational awareness to an operator of a vehicle
View Patent ↗Vehicular situational awareness systems, method and arrangements are disclosed herein. In one embodiment digitized video can be acquired by a camera on a vehicle, and utilizing pixel differentiation at least one area of interest in the digitized video can be identified. The area of interest could be, for example, a group of pixels that represent another vehicle, a sign etc. Attribute information for the area of interest, such as size, movement etc. of an object, can be acquired and then it can be determined if the attribute information is significant enough or important enough to set an alarm condition and notify the driver.
1. A method comprising:
acquiring, by a video acquisition module utilizing at least hardware, a digitized video comprising pixel data;
performing pixel differentiation to locate differentiations in the pixel data in a video frame of the digitized video, by a pixel differentiation module;
defining an area of interest in the pixel data of the video frame, by the pixel differentiation module, the area of interest comprising a pool of light produced by a headlight of a vehicle on the ground with an identifiable edge in front of the vehicle; and
detecting attribute information of the area of interest by an attribute detector to track edges of the pool of light to determine a distance and a sideways separation of the vehicle and to compare the edges with other attribute information for the vehicle to determine a speed of the vehicle.
2. The method of claim 1 , further comprising projecting a path of the vehicle.
3. The method of claim 1 , further comprising scanning at least one edge of the object to locate a point of interest.
4. The method of claim 1 , further comprising enhancing the pixel data by acquiring the radar data.
5. The method of claim 1 , further comprising utilizing a point at infinity to determine the attribute information comprises at least one attribute that is moving in relation to the earth.
6. The method of claim 1 , further comprising determining if the attribute information for the vehicle indicates that the vehicle represents a collision threat.
7. The method of claim 1 , further comprising triggering an alarm if the at least a portion of the vehicle represents a threat.
8. The method of claim 1 , wherein detecting attribute information of the area of interest comprises detecting where a light beam of the headlight of the vehicle hits the ground in front of a bumper of the vehicle.
9. The method of claim 1 , wherein detecting attribute information of the area of interest comprises detecting edges where a front tire of the vehicle touches the ground.
10. An apparatus comprising:
a video acquisition module utilizing at least hardware to acquire a digitized video comprising pixel data;
a pixel differentiation module to perform pixel differentiation to locate differentiations in the pixel data in a video frame of the digitized video and to define an area of interest in the pixel data of the video frame, the area of interest comprising a pool of light produced by a headlight of a vehicle on the ground with an identifiable edge in front of the vehicle; and
an attribute detector to detect attribute information of the area of interest to track edges of the pool of light to determine a distance and a sideways separation of the vehicle and to compare the edges with other attribute information for the vehicle to determine a speed of the vehicle.
11. The apparatus of claim 10 , further comprising a display to display information based on the attribute information.
12. The apparatus of claim 10 , further comprising a pixel group movement predictor to project a path of the vehicle.
13. The apparatus of claim 10 , wherein the pixel differentiation module defines the area of interest in the pixel data of the video frame by performing shape detection to detect a portion of a shape and performing optical character recognition to acquire textual and numerical content if the shape is a sign.
14. The apparatus of claim 10 , further comprising a pixel group movement detector to utilize a point at infinity to compare the attribute information with other attribute information to determine if the vehicle is moving in relation to the earth.
15. The apparatus of claim 10 , wherein the pixel differentiation module detects attribute information of the area of interest by detecting where a light beam of the headlight of the vehicle hits the ground in front of a bumper of the vehicle.
16. The apparatus of claim 10 , wherein the pixel differentiation module detects attribute information of the area of interest by detecting edges where a front tire of the vehicle touches the ground.
17. The apparatus of claim 10 , wherein the video acquisition module is sensitive to infra-red wavelength during low light conditions.
18. A computer program product for providing situational awareness, the computer program pro duct comprising:
a computer usable storage medium having computer usable program code embodied therewith, the computer usable program code comprising:
computer usable program code configured to perform operations, the operations comprising:
acquiring, by a video acquisition module utilizing at least hardware, a digitized video comprising pixel data;
performing pixel differentiation to locate differentiations in the pixel data in a video frame of the digitized video, by a pixel differentiation module;
defining an area of interest in the pixel data of the video frame, by the pixel differentiation module, the area of interest comprising a pool of light produced by a headlight of a vehicle on the ground with an identifiable edge in front of the vehicle; and
detecting attribute information of the area of interest by an attribute detector to track edges of the pool of light to determine a distance and a sideways separation of the vehicle and to compare the edges with other attribute information for the vehicle to determine a speed of the vehicle.
19. The computer program product of claim 18 , wherein the operations further comprise projecting a path of the vehicle.
20. The computer program product of claim 18 , wherein the operations further comprise scanning at least one edge of the object to locate a point of interest.
