Image processing system and method

The invention relates to an image processing system and method.

Image Resolution refers to the amount of information stored in an image. The larger the amount of information in an image file, the more detailed the detail can be. This resolution has a complex measure, typically measured in terms of the number of elements per inch.

Generally, when shooting, the size of the image that the camera can display is related to its maximum resolution. When photographing at the maximum resolution of the camera, the captured image has a fixed size. Then, when the size of the image to be displayed is large, we can only reduce the resolution of the image to get a larger size image. In this way, an image with a higher size and resolution can be obtained only by increasing the maximum resolution of the camera. In addition, the conventional camera generally only obtains the plane information of the scene to be photographed when shooting, that is, the distance between each object in the scene and the camera cannot be known, so that the image obtained by the shooting contains too little information. So that only a small amount of processing of the image can be done later.

In view of the above, it is necessary to provide an image processing system and method by which a large-sized and high-resolution image can be obtained.

An image processing system comprising:

a plurality of TOF cameras for separately capturing different areas of the scene to obtain a plurality of images, the images including distance information of points in the scene and the corresponding TOF camera;

An image capture card for combining the plurality of images to obtain a complete image of the captured scene, the complete image of the captured scene having a large size, high resolution, and including points in the captured scene and the corresponding TOF camera Distance information.

An image processing method includes the following steps:

The plurality of TOF cameras respectively capture different regions of the captured scene to obtain images of different regions of the captured scene at the same time, and images of different regions of the captured scene include points in the captured scene and corresponding TOF cameras. Distance information;

Combining images of different regions through an image capture card to obtain a complete image of the captured scene, the complete image of the captured scene has a large size, high resolution and includes points in the captured scene and corresponding TOF Camera distance information.

The image processing system and method use a plurality of cameras to respectively capture different regions of the captured scene, and combine the images through the image capture card to obtain a complete image of the captured scene, the complete image having a large size And high resolution.

Referring to FIG. 1, the image processing system of the present invention is used for photographing a scene to be photographed, and processing the captured image to obtain a large-sized and high-resolution image. A preferred embodiment of the image processing system includes a plurality of cameras 10 and an image capture card 20.

Each camera 10 is a TOF (Time-of-Flight) camera that provides the distance between points in the scene and the camera 10. The cameras 10 are arranged in a camera array in which each camera 10 has a different shooting angle so that different areas of the scene can be photographed.

As shown in FIG. 2, the cameras 10 include a total of nine cameras whose shooting angles are respectively directed from the first area A to the ninth area I of the subject 100. When the image processing system starts to work, the nine cameras 10 are simultaneously turned on, and the subject scene 100 is photographed at multiple angles, so that nine images 101-109 can be obtained at the same time. The nine images 101-109 are transmitted to the image capture card 20.

The image capture card 20 can be mounted in a computer system. When the camera 10 transmits the captured images 101-109 to the image capturing card 20, the image capturing card 20 combines the images 101-109 to obtain a complete image of the captured scene 100. . In the present embodiment, the nine images 101-109 are not overlapped as an example. In other embodiments, the nine images may partially overlap. Wherein, the complex image is combined to obtain another image, that is, the image synthesis technology belongs to the prior art, and details are not described herein again.

Assuming that the camera 10 is shooting at its maximum resolution, the size of the image that can be obtained is 10 inch * 10 inches. Obviously, the image size obtained by the image processing system is 30 inch * 30 inch, and its resolution is equal to each. The resolution of the image captured by the camera 10, that is, the maximum resolution of the camera 10. When a camera 10 is used for shooting, if the image size to be displayed is 30 inches*30 inches, the resolution of the image is significantly smaller than the original image captured by the camera 10.

In the present embodiment, only nine cameras 10 are taken as an example. In other embodiments, the image processing system may include more cameras, and the cameras may be arranged in other arrays, such as a circular arrangement, a circular multilayer. Arrangement, arc arrangement, and so on.

In addition, since the TOF camera is used in the present embodiment, the distance between each point in the scene 100 and the camera 10 can be obtained, so that the user can easily access the camera 10 for the complete image of the scene 100 that is obtained later. Images that are separated by a certain distance are erased or replaced for more post-processing functions.

Referring to FIG. 3 together, a preferred embodiment of the image processing method of the present invention includes the following steps:

Step S1: The plurality of cameras 10 respectively capture different areas of the scene 100 to obtain images 101-109 of different areas A-I of the scene 100 at the same time. Each image includes a distance between each point in the scene 100 and the corresponding camera 10.

Step S2: Images 101-109 of different areas A-I of the scene 100 at the same time are transmitted to the image capture card 20.

Step S3: The image capture card 20 combines the images 101-109 to obtain a complete image of the captured scene 100. The complete image of the scene 100 includes the distance between each point in the scene 100 and the corresponding camera 10, and has a large size and a high resolution.

The image processing system and method use the plurality of cameras 10 to respectively capture different areas of the scene 100, and combine the images 101-109 through the image capturing card 20 to obtain a complete image of the scene 100. This complete image has a large size and high resolution. Moreover, since the complete image of the captured scene 100 includes the distance between each point in the captured scene 100 and the corresponding camera 10, the user can easily access the camera 10 for the complete image of the captured scene 100 obtained later. Images that are separated by a certain distance are erased or replaced for more post-processing functions.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
