Embodiment 1

[0092] FIG. 1 is a schematic structural diagram of a camera system based on PC Camera in Embodiment 1 of the present invention. As shown in FIG. 1 , the camera system based on PC Camera in this embodiment includes: PC Camera and PC.

[0093] The PC Camera in this embodiment includes: two cameras, an image processing unit, an image matching correction unit, an image synthesis unit, an image compression unit, and an image transmission unit.

[0094] Specifically, the two cameras of PC Camera simulate human eyes based on the principle of stereoscopic imaging, and the optical axes of the two cameras have an intersection point on the imaging plane, that is, the two cameras aim at the target image from different angles, but There is a focal point on the plane where the target image is located, see Figure 2. In practical applications, the distance between the two cameras is preferably less than or equal to 6-7 cm between the human eyes.

[0095] The two cameras are respectively use...

Embodiment 2

[0133] In this embodiment, the two cameras are still set in one PC Camera, but the processing such as stereo synthesis is implemented by the PC.

[0134] FIG. 5 is a schematic structural diagram of a camera system based on PC Camera in Embodiment 2 of the present invention. As shown in FIG. 5 , the camera system based on the PC Camera in this embodiment includes: a PC camera and a PC.

[0135] The PC Camera in this embodiment includes: two cameras, an image processing unit, an image compression unit and an image transmission unit.

[0136] The optical axes of the two cameras have an intersection on the imaging plane, which are respectively used to generate one image signal and output it to the image processing unit.

[0137] The image processing unit performs denoising processing on the two received image signals respectively, and outputs them to the image compression unit.

[0138] The image compression unit is configured to compress the image signal output by the image pro...

Abstract

The invention discloses a PC Camera, a photographing system based on the PC Camera and a photographing method based on the PC Camera. The invention is based on the three-dimensional image formation principle, two camera heads are arranged in the PC Camera, each camera head can generate a two-dimensional plane image, then two two-dimensional plane images are synthesized, and a synthesized two-dimensional plane image and the elevation information of the two-dimensional plane image can be obtained. Because the elevation information can reflect the distance of each pixel vertical to the image in the plane direction in the two-dimensional plane image, the synthesized two-dimensional plane image is colored and decorated according to the corresponding elevation information, namely a three-dimensional image can be obtained through one PC Camera.

Description

technical field [0001] The invention relates to camera technology based on a personal computer (PC), in particular to a PC Camera, a camera system based on a PC Camera, and a camera method based on a PC Camera. Background technique [0002] The existing PC Camera has a camera, which is a relatively commonly used camera. The PC Camera is connected with the PC, and the image signal generated by the camera is de-noised and then output to the PC for display and output by the PC. [0003] However, the existing PC Camera can only capture two-dimensional plane images through its camera, but cannot realize stereoscopic imaging, thereby failing to meet user needs. Contents of the invention [0004] In view of this, the present invention provides a PC Camera, a camera system based on the PC Camera, and a camera method based on the PC Camera, capable of realizing stereoscopic imaging. [0005] A kind of PC Camera provided by the present invention comprises: two camera heads, image ...
