Abstract

A method of partial frame perception, comprising receiving a bottom portion of an inverted image, detecting traffic areas of interest in the bottom portion of the inverted image, streaming the detected traffic areas of interest to a perception processor, receiving a top portion of the inverted image, detecting stationary areas of interest in the top portion of the inverted image and streaming the detected stationary areas of interest to the perception processor.

Claims (30)

1. A method of partial frame perception, comprising:

receiving a traffic portion of an inverted image in a half-row rolling, shutter format;

detecting traffic areas of interest in a rectangular traffic portion of the inverted image beginning with the traffic portion nearest a vehicle based on an inverted image format and prioritizing the detection of the traffic areas of interest;

streaming the detected traffic areas of interest to a perception processor;

receiving a stationary portion of the inverted image in the half-row rolling shutter format, wherein the inverted image only includes the rectangular traffic portion and a rectangular stationary portion;

detecting stationary areas of interest in the rectangular stationary portion of the inverted image beginning with the stationary portion nearest the vehicle based on the inverted image format after detection of the traffic areas of interest; and

streaming the detected stationary areas of interest to the perception processor.

2. The method of partial frame perception of claim 1 , further comprising inverting a non-inverted image based on flipping the non-inverted image.

3. The method of partial frame perception of claim 1 , further comprising asymmetrically filtering the traffic portion of the inverted image.

4. The method of partial frame perception of claim 1 , further comprising asymmetrically filtering the stationary portion of the inverted image.

5. The method of partial frame perception of claim 1 , further comprising integrating the traffic portion of the inverted image and the stationary portion of the inverted image.

6. The method of partial frame perception of claim 1 , further comprising storing the stationary portion of the inverted image to a top frame buffer.

7. The method of partial frame perception of claim 1 , further comprising storing the traffic portion of the inverted image to a bottom frame buffer.

8. The method of partial frame perception of claim 1 , further comprising receiving a non-inverted image and inverting the non-inverted image.

9. The method of partial frame perception of claim 1 , wherein the traffic portion of the inverted image is received from a first camera and the stationary portion of the inverted image is received from a second camera.

10. A method of partial frame perception, comprising:

receiving a rectangular traffic portion of an inverted image in a half-row rolling shutter format;

storing the traffic portion of the inverted image to a bottom frame first in first out buffer;

detecting traffic areas of interest in the traffic portion of the inverted image beginning with the traffic portion nearest a vehicle based on an inverted image format in the bottom frame first in first out buffer and prioritizing the detection of the traffic areas of interest;

receiving a rectangular stationary portion of the inverted image in the half-row rolling shutter format, wherein the inverted image only includes the rectangular traffic portion and the rectangular stationary portion;

storing the stationary portion of the inverted image to a top frame first in first out buffer; and

detecting stationary areas of interest in the stationary portion of the inverted image beginning with the stationary portion nearest the vehicle based on the inverted image format in the top frame first in first out buffer after detection of the traffic areas of interest.

11. The method of partial frame perception of claim 10 , further comprising inverting a non-inverted image based on flipping the non-inverted image.

12. The method of partial frame perception of claim 10 , further comprising asymmetrically filtering the traffic portion of the inverted image.

13. The method of partial frame perception of claim 10 , further comprising asymmetrically filtering the stationary portion of the inverted image.

14. The method of partial frame perception of claim 10 , further comprising integrating the traffic portion of the inverted image and the stationary portion of the inverted image.

15. The method of partial frame perception of claim 10 , further comprising streaming the detected traffic areas of interest to a perception processor.

16. The method of partial frame perception of claim 10 , further comprising streaming the detected stationary areas of interest to a perception processor.

17. The method of partial frame perception of claim 10 , further comprising receiving a non-inverted image and inverting the non-inverted image.

18. The method of partial frame perception of claim 10 , wherein the traffic portion of the inverted image is received from a first camera and the stationary portion of the inverted image is received from a second camera.
