Abstract

The accident avoiding system includes an image obtaining unit, a detection module, a location analysis module, and a determination module. The image obtaining unit captures the image of the scene behind the car. The detection module analyzes whether there is a moving object in the captured images. The location analysis module analyzes the relative distance and the relative position between the moving object and the car. The determination module determines the warning level according to the analyzed results for preventing accidents. The disclosure further provides an accident avoiding method.

Claims

1. An accident avoiding system, comprising:

an image obtaining unit configured to capture images, each of the captured images comprising a distance information including distances between points on an object and the image obtaining unit;

a detection module configured to analyze the captured images and the distance information to determine whether there is a moving object;

a location module configured to determine a relative distance and a relative position between the moving object and the image obtaining unit; and

a determination module configured to determine whether the relative position is within an operating range of a door and whether the relative distance is smaller than a predetermined distance.

2. The accident avoiding system of claim 1, wherein the determination module transmits a first control signal when the relative position is within the operating range of the door and the relative distance is smaller than the predetermined distance and the determination module transmits a second control signal upon one of conditions that the relative position is out of the operating range of the door and that the relative distance is larger than or equal to the predetermined distance.

3. The accident avoiding system of claim 2, further comprising:

a first warning unit configured to provide a first warning signal when the first warning unit receives the first control signal.

4. The accident avoiding system of claim 3, further comprising:

a sensing unit configured to detect whether a door open unit is touched.

5. The accident avoiding system of claim 4, wherein the first warning unit further provides a second warning signal when the first warning unit receives the second control signal and the door open unit is touched.

6. The accident avoiding system of claim 4, further comprising:

a second warning unit configured to provide a third warning signal during receiving the first control signal and a fourth warning signal during receiving the second control signal if the door open unit is touched.

7. The accident avoiding system of claim 1, wherein the image obtaining unit is a depth-sensing camera.

8. The accident avoiding system of claim 7, wherein the depth-sensing camera is a time of flight camera.

9. The accident avoiding system of claim 1, further comprising:

a speed analysis module configured to analyze at least two of the captured images and the corresponding distance information to estimate a speed of the moving object for the determination module.

10. An accident avoiding method, comprising:

using an image obtaining unit to capture images, each of the captured images comprising a distance information including distances between points on an object and the image obtaining unit;

analyzing the captured images and the distance information to determine whether there is a moving object;

determining a relative distance and a relative position between the moving object and the image obtaining unit; and

determining whether the relative position is within an operating range of a door and whether the relative distance is smaller than a predetermined distance.

11. The accident avoiding method of claim 10, further comprising:

transmitting a first control signal when the relative position is within the operating range of the door and the relative distance is smaller than the predetermined distance; and

transmitting a second control signal upon one of conditions that the relative position is out of the operating range of the door and that the relative distance is larger than or equal to the predetermined distance.

12. The accident avoiding method of claim 11, further comprising:

providing a first warning signal by a first warning unit when the first control signal is received.

13. The accident avoiding method of claim 12, further comprising:

detecting whether a door open unit is touched or not.

14. The accident avoiding method of claim 13, further comprising:

providing a second warning signal by the first warning unit when the second control signal is received and the door open unit is touched.

15. The accident avoiding method of claim 13, further comprising:

providing a third warning signal by a second warning unit during receiving the first control signal if the door open unit is touched; and

providing a fourth warning signal by the second warning unit during receiving the second control signal if the door open unit is touched.

16. The accident avoiding method of claim 10, wherein the image obtaining unit is a depth-sensing camera.

17. The accident avoiding method of claim 16, wherein the depth-sensing camera is a time of flight camera.

18. The accident avoiding method of claim 10, further comprising:

analyzing at least two of the captured images and the corresponding distance information to estimate a speed of the moving object for determining whether the relative distance is smaller than a predetermined distance.
