Embodiment 1

[0088] The first preferred embodiment of the present invention is to correct the image of the stereoscopic digital camera with the first camera module and the second camera module, the stereo digital camera with the first camera module and the second camera module is due to the difference between the image sensing devices , there are differences in color and brightness between the two captured images, and the difference will change with changes in the environment. When taking still photos, it can be manually processed by image processing software on the computer, but for videos, if the same method is used, the post-processing workload will be huge. Therefore, based on the consumer-level stereo digital camera at present, the first and second videos captured often have obvious deviations in color and brightness in the first and second two-way images.

[0089] The image correction method of described stereo camera, comprises the steps:

[0090] S1. Obtain the color deviation rat...

Embodiment 2

[0117] The second preferred embodiment of the present invention is also to modify the image of the stereo digital camera with the first and second camera modules. The difference from the first preferred embodiment is that the color brightness of the second camera module is modified to approach the first Camera module, subsequent image reprocessing is also based on the first camera module, and the image correction method of the stereo camera includes the following steps:

[0118] S1. Obtain the color deviation rates of the first and second camera modules in different color temperature ranges;

[0119] S2. Measure the color temperature of the use environment, calculate the color temperature interval of the use environment color temperature, and determine the current color deviation rate;

[0120] S3. Correcting the second image according to the current color deviation rate;

[0121] S4. Synthesize the first image and the corrected second image into one stereo image data.

[01...

Embodiment 3

[0146] The above-mentioned first preferred embodiment and the second preferred embodiment both use the correction of the three primary colors of red, green and blue to achieve the purpose of correcting the image. The difference between the third preferred embodiment of the present invention and the above two embodiments is that it adopts The way to correct the YUV color space of brightness and chromaticity, the specific correction process is exactly the same as above, just replace all the above RGB values ​​with YUV, for example, the color components of the first camera module in N color temperature environments The average value is (Ya1, Ua1, Va1), (Ya2, Ua2, Va2)...(YaN, UaN, VaN); the average value of the color components of the second camera module is (Yb1, Ub1, Vb1), (Yb2, Ub2, Vb2)...(YbN, UbN, VbN);

[0147] For another example, the color deviation rate between the lowest and highest color temperature of the first camera module and the second camera module in the light ...

Abstract

The invention relates to a method and system for correcting images shot in a stereoscopic mode. The method for correcting the images shot in the stereoscopic mode comprises the following steps that S1, the color deviation ratio of two camera modules used for stereoscopic shooting in a standard color temperature environment is acquired; S2, the color temperature of a used environment is measured, and the current color deviation ratio is determined; S3, two ways of images acquired by the two camera modules are corrected according to the current color deviation ratio. According to the method and system, the deviation of all ways of images on color and brightness can be adjusted dynamically in real time, the influence of the difference of an image sensor and environment light on imaging is removed, and the watching comfort level and the stereoscopic feeling can be obviously improved.

Description

technical field [0001] The invention relates to the field of stereo imaging, and more specifically, to an image correction method and system for stereo imaging. Background technique [0002] When shooting stereoscopic video images, at least two images need to be collected at the same time, such as the first image and the second image corresponding to the first and second eye images of people respectively. The first image and the second image are spliced ​​and synthesized. In the process of acquiring the first image and the second image, due to the individual differences between the first image sensor and the second image sensor, the color and brightness of the two images are significantly different, resulting in the inability to synthesize a high-quality stereoscopic image . [0003] For current digital cameras, the collection of front-end data requires high-precision photosensitive image sensors. Image sensors are mainly divided into Charge-coupled Device (CCD) image sens...
