The display device for automatically adjusting the parallaxes of the stereo images has the advantages of precise parallax detection of the stereo images, simple parallax adjustment and the like; additionally, the parallax between the first image and the second image which is shot from different angles for the same object is obtained; the calculated adjustment parallax is applied to the first image and the second image; and the first image and the second image with adjusted parallaxes are output.
Description
Technical field
The utility model relates to camera head and image parallactic adjustment field thereof, especially relates to a kind of display unit of automatic adjustment stereo-picture parallax.
Background technology
When the human eyes are seen target, exist different between the horizontal level of the horizontal level of the image of seeing with left eye and the image seen with right eye.And the corresponding distance in the interval between two is called as binocular parallax.In this case, examine the image identical, then when the people watches this image, can experience stereoeffect with real image if observe with two.The three-dimensional camera shooting device generates the stereogram picture based on a plurality of visual point images that generated respectively by a plurality of image pickup parts, and this stereogram is looked like to be presented in the stereopsis demonstration.The third dimension of the three-dimensional view picture that is photographed by the three-dimensional camera shooting device can receive the influence of distance of user's eyes, so about the stereoscopic function of three-dimensional camera shooting device, have the bigger problem of individual difference.Therefore, in the three-dimensional camera shooting device, based on user's operation and can adjust the parallax of a plurality of visual point images, can adjust the third dimension of stereogram picture thus.The image of taking.In this case, if move right the image of being taken by left side camera with the adjustment parallax, then image possibly seem outstanding forward from screen.In addition, if be moved to the left the image of being taken by the right camera, then image possibly seem at the screen rear.Therefore, can adjust the stereoeffect of image through changing parallax.
Yet present stage has problems, and for example, in the time of when the parallax amount of obtaining according to a plurality of visual point images that obtained by camera part self has problems, maybe can't detecting parallax adjustment object, can have the problem that can't suitably carry out the parallax adjustment.
Summary of the invention
The utility model purpose provides a kind of display unit of automatic adjustment stereo-picture parallax.Technical problems such as the existing stereo-picture parallax of prior art can't detect to solve, parallax adjustment difficulty.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: adjust the display unit of stereo-picture parallax automatically, comprise camera head, parallax amount detection module, parallax adjustment calculation unit, output unit, parallax adjusting module; Said camera head comprises two video cameras; Said parallax amount detection module comprises parallax estimation device, parallax amount receiver module; Wherein the parallax amount receiver module is used for receiving the parallax amount that pixel that video camera produces first image and second image has same disparity, and this parallax amount receiver module is connected with parallax estimation device; Said parallax adjustment calculation unit is connected with the parallax amount detection module, and this parallax adjustment calculation unit representes parallax amount with the histogram of parallax frequency, and histogrammic value added up produces the integral density histogram; Said parallax adjusting module is connected with the parallax adjustment calculation module through output unit.
As preferably, said video camera generates a plurality of images through taking same subject from different perspectives to each frame.
As preferably, said parallax adjustment calculation unit is provided with the relation between input parallax and the adjustment parallax through minimum value and the maximum of using histogrammic mean value of integral density and input parallax, and calculates the adjustment parallax based on the relation that is provided with.
As preferably, said parallax adjusting module does not carry out parallax adjustment first time unusually through judging parallax amount, and parallax amount has carries out second time parallax unusually and adjust.
The utlity model has advantages such as the stereo-picture parallax detects accurately, the parallax adjustment is simple, through taking first image that same target obtains and the parallax between second image from different perspectives; The histogram that use obtains through the frequency of calculating estimated parallax calculates the adjustment parallax between first image and second image; Be applied to first image and second image with the adjustment parallax that will calculate, and first image and second image of parallax have been adjusted in output.
Description of drawings
Fig. 1 is the block diagram of the utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical scheme of the utility model is further specified.
Fig. 1 is the block diagram of the utility model.Can know by figure, adjust the display unit of stereo-picture parallax automatically, mainly form by camera head, parallax amount detection module, parallax adjustment calculation unit, output unit, parallax adjusting module etc.; Said camera head comprises two video cameras, and video camera generates a plurality of images through taking same subject from different perspectives to each frame.The parallax amount detection module comprises parallax estimation device, parallax amount receiver module; Wherein the parallax amount receiver module is used for receiving the parallax amount that pixel that video camera generates first image and second image has same disparity, and this parallax amount receiver module is connected with parallax estimation device; Disparity estimator is estimated through taking first image that same target produces and the parallax between second image from different perspectives.First image and second graphical representation separate with two imaging devices of the corresponding distance of binocular parallax through use takes the image that same target obtains.One of first image and second image can be the left images of taking in the left side, and another image can be the right image of taking on the right side.Disparity estimator compares left image and right image, and estimates the parallax between the match point in left image and the right image.
The parallax adjustment calculation unit is connected with the parallax amount detection module, and this parallax adjustment calculation unit uses the histogram that obtains through the frequency of calculating the parallax of being estimated by disparity estimator to calculate the adjustment parallax between first image and second image.Here, the number of times of same disparity appears in the frequency representation of estimated parallax between first image and second image.The parallax adjustment calculation unit calculates (-) adjustment parallax and (+) adjustment parallax between first image and second image through using the histogram relevant with the parallax frequency.
The parallax adjusting module is connected with the parallax adjustment calculation module through output unit; The parallax adjustment calculation unit is provided with the relation between input parallax and the adjustment parallax through minimum value and the maximum of using histogrammic mean value of integral density and input parallax, and calculates the adjustment parallax based on the relation that is provided with.The parallax adjusting module does not carry out the parallax adjustment first time unusually through judging parallax amount, and parallax amount has carries out the parallax adjustment second time unusually.
