Abstract

A driving support system with plural dimension processing units (DPUs) for indicating a condition of a surrounding area is disclosed. The driving support system of a vehicle includes plural image capturing devices disposed around the vehicle; at least a dimension processing unit (DPU) connected with the plural image capturing devices for receiving images from the plural image capturing devices and then producing plural related depth maps; a controller connected with the DPU for receiving the plural related depth maps and then producing an indicating data; and a display device connected with the controller for displaying the indicating data around the vehicle in a vertical view.

Claims

1. A driving support system of a vehicle comprising:

plural image capturing devices disposed around said vehicle;

plural dimension processing units (DPUs) connected with said plural image capturing devices for receiving images from said plural image capturing devices and then producing plural related depth maps; and

a controller connected with said plural DPUs for receiving said plural related depth maps and indicating a condition of a surrounding area of said vehicle.

2. The driving support system according to claim 1, wherein said plural image capturing devices are cameras.

3. The driving support system according to claim 1, wherein each of said plural DPUs further comprises:

an intrinsic camera parameter calibration module for receiving images from said plural image capturing devices;

a disparity estimation module connected with said intrinsic camera parameter calibration module;

an extrinsic camera parameter estimation module connected with said disparity estimation module;

a depth estimation module connected with said extrinsic camera parameter estimation module; and

a depth fusion module connected with said depth estimation module for outputting said plural related depth maps.

4. The driving support system according to claim 1, wherein more than one of said plural image capturing devices is connected to one of said plural DPUs.

5. The driving support system according to claim 1, further comprising a display device connected with said controller for indicating said condition of said surrounding area of said vehicle in a vertical view.

6. The driving support system according to claim 1, further comprising a GPS/GPRS module communicating with said controller for providing a display data.

7. The driving support system according to claim 6, wherein said display data comprises a unit'"'"'s ID, a time, a GPS'"'"'s latitude and longitude, a speed, a direction, a temperature, a device'"'"'s status, an event number, a report configuration parameter, and a mixture thereof.

8. A driving support system of a vehicle comprising:

plural image capturing devices disposed around said vehicle;

at least a dimension processing unit (DPU) connected with said plural image capturing devices for receiving images from said plural image capturing devices and then producing plural related depth maps;

a controller connected with said DPU for receiving said plural related depth maps and then producing an indicating data; and

a display device connected with said controller for displaying said indicating data around said vehicle in a vertical view.

9. The driving support system according to claim 8, wherein said plural image capturing devices are cameras.

10. The driving support system according to claim 8, wherein said DPU further comprises:

an intrinsic camera parameter calibration module for receiving images from said plural image capturing devices;

a disparity estimation module connected with said intrinsic camera parameter calibration module;
