Abstract

An automatic installation method for video wall comprises the following steps. In the step (a), it employs a control system to output a plurality of identifiable images to a plurality of video devices of the video wall. In the step (b), it employs an image capturing device to capture the plurality of identifiable images. In the step (c), based-on the plurality of identifiable images, it employs the image capturing device to determine position data for the video devices, frame dimension of each of the video devices and spacings between adjacent video devices, and calibrate the identifiable images to obtain a setting value thereof. In the step (d), based-on the position data for the video devices, the frame dimension of each of the video devices and spacings between adjacent video devices and the setting value, it employs the control system to install and set-up the video wall automatically.

First claim

What is claimed is:

1. A method for automatically installing a video wall, comprising:
(a) an image output controller outputting each of a plurality of identifiable images to a corresponding one of a plurality of video devices that form the video wall;
(b) an imaging device capturing the plurality of identifiable images displayed on the video wall;
(c) based on the plurality of identifiable images, a first processor determining position data for the video devices and spacings between adjacent video devices and frame data of the video devices,
wherein the first processor obtains a size of an image of the video wall, calculates a ratio between the size and an actual size of the video wall, recognizes image frames of the video devices and distances between the image frames using image recognition, and calculates physical distances, including horizontal spacing and vertical spacing, between the video devices based on the ratio and the recognized distances between the image frames; and
(d) based on the position data for the video devices, a second processor automatically setting up image display of the video wall, the second processor being same as or different from the first processor.

2. The method of claim 1 , further comprising: based on the plurality of identifiable images, the first processor calibrating the identifiable images to obtain an image setting value.

3. The method of claim 2 , further comprising: the second processor calibrating images of the video devices based on the image setting value.

4. The method of claim 1 , further comprising, before step (a): connecting the plurality of video devices that form the video wall to output ports that are coupled to the image output controller, in a one-to-one relationship without predetermined correspondence between the output ports and the video devices.

5. The method of claim 1 , wherein the size is at least one of a length and a width.

6. An image capture device, comprising:
a processor;
an imaging module coupled to the processor;
a memory coupled to the processor; and
a video wall automatic-installation application program stored in the memory and configured to be executed by the processor, for processing a plurality of identifiable images which are displayed on a video wall and captured by the imaging module, to determine position data for a plurality of video devices that form the video wall and spacings between adjacent video devices and frame data of the video devices, including to obtain a size of an image of the video wall, calculate a ratio between the size and an actual size of the video wall, to recognize image frames of the video devices and distances between the image frames using image recognition, and to calculate physical distances, including horizontal spacing and vertical spacing, between the video devices based on the ratio and the recognized distances between the image frames.

7. The image capture device of claim 6 , wherein the video wall automatic-installation application program is configured to be executed by the processor to calibrate the identifiable images to obtain an image setting value.

8. The image capture device of claim 6 , wherein the size is at least one of a length and a width.

9. A system for automatically installing a video wall, comprising:
an image output controller coupled to a plurality of video devices that form a video wall, and outputting one of a plurality of identifiable images to each of the plurality of video devices;
an imaging device, for capturing the plurality of identifiable images displayed on the video wall;
a first processor; and
a memory storing a video wall automatic-installation application program which is configured to be executed by the first processor, for determining position data for the plurality of video devices based on the captured plurality of identifiable images and spacings between adjacent video devices and frame data of the video devices based on the captured identifiable images, including to obtain a size of an image of the video wall, to calculates a ratio between the size and an actual size of the video wall, to recognize image frames of the video devices and distances between the image frames using image recognition, and to calculate physical distances, including horizontal spacing and vertical spacing, between the video devices based on the ratio and the recognized distances between the image frames,
a second processor which automatically sets up image display of the video wall based on the position data for the video devices, the second processor being same as or different from the first processor.

10. The system of claim 9 , wherein the video wall automatic-installation application program is configured to be executed by the first processor to calibrate the identifiable images to obtain an image setting value.

11. The system of claim 9 , wherein the second processor calibrates images of the video devices based on the image setting value, the spacings between adjacent video devices and the frame data of the video devices.

12. The system of claim 9 , wherein the imaging device, the first processor and the memory storing the video wall automatic-installation application program form an image capture device and wherein the second processor is different from the first processor.

13. The system of claim 9 , wherein the image output controller, the first processor and the memory storing the video wall automatic-installation application program form a control system and wherein the second processor is the same as the first processor.

14. The system of claim 9 , wherein the size is at least one of a length and a width.
