Problems solved by technology

However, most of the handheld stereoscopic shooting equipment, such as mobile terminals, are non-professional shooting equipment and are not equipped with corresponding fixing devices. The ground plane is parallel, which affects the shooting effect, which in turn affects the viewing effect of the image

Embodiment Construction

[0039] The existing digital image processing technology is very mature. The so-called image transformation in digital image processing is the coordinate transformation from the source image to the target image. The new coordinates of the point. Therefore, digital image processing technology can perform transformation processing such as twisting, stretching, scaling or cropping on any digital image.

[0040] In addition, with the development of electronic technology, accelerometers are becoming more and more miniaturized, but their accuracy is getting higher and higher, and they can be sensitive to small changes in acceleration, and are now widely used in various handheld devices.

[0041] The basic idea of ​​the present invention is: during the shooting process, use the accelerometer to measure the value of the gravitational acceleration suffered by the hand-held stereo camera device, and calculate the center connection line of the dual cameras on the hand-held stereo camera d...

Abstract

The invention discloses a method for automatically adjusting shake of hand-held three-dimensional shooting equipment, which comprises the following steps of: in a shooting process, measuring the value of gravitational acceleration of the hand-held three-dimensional shooting equipment by using an accelerometer; calculating an included angle between a central connecting line of double cameras on the hand-held three-dimensional shooting equipment and a horizontal plane according to the measured value of the gravitational acceleration; and converting a left eye image and a right eye image which are acquired by shooting according to the calculated included angle. The invention also discloses a device for automatically adjusting the shake of the hand-held three-dimensional shooting equipment. Due to the adoption of the method and the device, the influence of the shake of the hand-held three-dimensional shooting equipment on image shooting quality can be effectively reduced and image viewing effect is further enhanced.

Description

technical field [0001] The invention relates to stereoscopic image shooting technology, in particular to a method and device for automatically adjusting the shaking of a hand-held stereoscopic shooting device. Background technique [0002] At present, various methods can be used to display stereoscopic images, such as: color division method, light division method, time division method and grating method, etc., all of which are realized by utilizing the parallax characteristics of human eyes. Although the specific implementation methods of the above methods are different, the basic principles on which they are based are similar, that is, when shooting, two shooting devices placed side by side, such as cameras, represent the left eye and right eye of a person respectively, and the two The shooting equipment synchronously shoots two kinds of images with slight horizontal parallax; when projecting, the two kinds of images are respectively loaded into the left-eye projection devi...
