Abstract

A blind spot detection alert system. The system comprises two image capturing modules, a processing module, a first display module and a second display module. The two image capturing modules capture a right image and a left image respectively. The first display module is disposed on the right of the second display module. The processing module receives the right image and the left image to analyze a car moving direction. When the processing module determines the car moving direction is a right direction, the first display module displays the right image. When the processing module determines the car moving direction is a left direction, the second display module displays the left image. The processing module calculates a distance to a coming car, a moving direction of the coming car and a speed of the coming car according to the image to get an alert message.

Claims

1. A blind spot detection alert system, comprising:

two image capturing modules, capturing a right image and a left image respectively;

a first display module and a second display module, wherein the first display module is installed on the right side of the second display module; and

a processing module, receiving the right image and the left image to perform an image processing to analyze a car moving direction, such that when the car moving direction is determined to be right, the right image is displayed by the processing module at the first display module; and

when the car moving direction is determined to be left, the left image is displayed by the processing module at the second display module.

2. The blind spot detection alert system of claim 1, wherein the processing module calculates a distance to a coming car, a moving direction of the coming car or a speed of the coming car, and compare the distance to the coming car, the moving direction of the coming car or the speed of the coming car with a safety range to determine issuing an alert message;

wherein the safety range is determined by the processing module range according to the right image or the left image.

3. The blind spot detection alert system of claim 1, further comprising at least one head-up display module for displaying an object pattern, a distance to a coming car, a moving direction of the coming car, a speed of the coming car or an alert message.

4. The blind spot detection alert system of claim 3, wherein the processing module recognizes at least one object in the right image or the left image, and converts the at least one object into the object pattern, and the object pattern is displayed by the head-up display module.

5. The blind spot detection alert system of claim 1, wherein the processing module analyzes the car moving direction according to a turning information or a direction light information of a steering wheel.

6. The blind spot detection alert system of claim 5, wherein the processing module detects a black shadow or an approaching optical flow according to the turning information or the direction light information, so as to determine an alert message.

7. The blind spot detection alert system of claim 5, wherein the processing module dynamically adjusts a computing resource, a screening threshold of a false alarm, a screen resolution or a frame rate used for processing the right image and the left image according to the car moving direction.

8. A blind spot detection alert system, comprising:

an image capturing module, capturing a right image or a left image;

a processing module, calculating a distance to a coming car, a moving direction of the coming car or a speed of the coming car according to the right image or the left image, and setting a safety range, and comparing the distance to the coming car, the moving direction of the coming car or the speed of the coming car with the safety range to determine an alert message; and

a head-up display module, displaying the distance to the coming car, the moving direction of the coming car, the speed of the coming car or the alert message.

9. The blind spot detection alert system of claim 8, wherein the processing module recognizes at least one object in the right image or the left image, and converts the at least one object into an object pattern, and the object pattern is displayed by the head-up display module.

10. The blind spot detection alert system of claim 8, wherein the processing module determines the car moving direction according to a turning information or a direction light information of a steering wheel.

11. The blind spot detection alert system of claim 10, wherein the processing module dynamically adjusts a computing resource, a screening threshold of a false alarm, a screen resolution or a frame rate of the car moving direction according to the car moving direction.

12. The blind spot detection alert system of claim 8, further comprising a first display module for displaying the right image.

13. The blind spot detection alert system of claim 8, further comprising a first display module and a second display module, and the first display module being installed on the right side of the second display module, and the right image being displayed by the first display module, and the left image being displayed by the second display module.

14. A blind spot detection alert system, comprising:

two image capturing module, capturing a right image and a left image; and

a processing module, processing the right image and the left image, and dynamically adjusting a computing resource, a screening threshold of a false alarm, a screen resolution or a frame rate used for processing the right image and the left image according to a car moving direction.

15. The blind spot detection alert system of claim 14, further comprising a display module for displaying the right image or the left image.

16. The blind spot detection alert system of claim 14, wherein the processing module calculates a distance to a coming car, a moving direction of the coming car or a speed of the coming car and sets a safety range according to the right image and the left image, and the distance to the coming car, the moving direction of the coming car or the speed of the coming car are compared with the safety range to determine an alert message.

17. The blind spot detection alert system of claim 14, wherein the processing module recognizes at least one object in the right image or the left image, and converts the at least one object into an object pattern, and the blind spot detection alert system further comprises at least one head-up display module for displaying the object pattern and a distance to a coming car, a moving direction of the coming car, a speed of the coming car or an alert message calculated by the processing module.
