Description
一种立 像装置 技术领域 An image device
本实用新型涉及立体成像技术领域， 特别是指一种立体摄像装置。 背景技术 The utility model relates to the technical field of stereo imaging, in particular to a stereo camera device. Background technique
随着数字成像技术的日趋成熟， 立体成像技术正在快速的发展。 立体 成像技术主要利用人的两只眼睛的视差特性实现的， 其具体实现方式主要 包括： 色分法、 光分法、 时分法和光栅法等。 具体实现方式虽然有多种， 但所有实现方式的原理相似， 即： 利用两台并列安置的摄影机， 同步拍摄 出两个略带水平视差的画面， 这两台摄影机分别代表人的左眼与右眼。 放 映时， 将两个画面分别装入左眼放映装置与右眼放映装置， 左眼放映装置 与右眼放映装置同步运转， 同时将画面放映出来， 形成包括左眼图像与右 眼图像的双影图像。 观看者通过一些特殊设备， 例如： 偏光眼镜等， 使左 眼只能看到左眼图像， 右眼只能看到右眼图像， 再通过双眼的汇聚功能， 分别将左眼图像、 右眼图像叠合在视网膜上， 由大脑神经产生三维立体的 视觉效果。 With the maturity of digital imaging technology, stereo imaging technology is rapidly developing. Stereoscopic imaging technology is mainly realized by the parallax characteristics of two eyes of human beings. The specific implementation methods mainly include: color separation method, light division method, time division method and grating method. Although there are many specific implementation methods, the principles of all implementations are similar, namely: using two cameras arranged side by side, two pictures with horizontal parallax are simultaneously captured, and the two cameras respectively represent the left eye and the right of the person. eye. During the screening, the two screens are respectively loaded into the left-eye projection device and the right-eye projection device, and the left-eye projection device and the right-eye projection device are synchronized, and the screen is projected to form a double shadow including the left-eye image and the right-eye image. image. The viewer uses some special equipment, such as polarized glasses, so that the left eye can only see the left eye image, the right eye can only see the right eye image, and then through the binocular convergence function, the left eye image and the right eye image respectively. Superimposed on the retina, the three-dimensional visual effect is produced by the brain nerves.
以上描述说明： 无论釆用哪种实现方式， 关键在于必须做到观看者的 左眼与右眼看到的图像不能完全相同， 即： 对应于左眼的画面只被左眼观 察到， 对应于右眼的画面只被右眼观察到。 如此， 具有立体效果的拍摄装 置必须带有两个摄像头进行成像， 并对图像进行处理。 但是， 现有的拍摄 装置存在一些缺点， 主要表现在以下三个方面： The above description explains: Regardless of which implementation is used, the key is that the image seen by the viewer's left eye and right eye must not be exactly the same, ie: the picture corresponding to the left eye is only observed by the left eye, corresponding to the right The picture of the eye is only observed by the right eye. In this way, a stereoscopic camera must have two cameras for imaging and processing the image. However, existing camera devices have some shortcomings, mainly in the following three aspects:
首先， 两个摄像头由于物理性能不可能完全相同， 比如： 焦距不完全 相同， 因此， 会造成两个摄像头在聚焦性能上不完全一致， 进而导致左右 视频清晰度不完全一致， 最终导致图像成像模糊。
其次， 两个摄像头在安装对位上存在误差， 导致双摄像头拍摄的图像在 视角的水平和倾斜上不完全一致， 进而导致图像处理时出现偏差， 最终导 致图像产生叠影。 First of all, the two cameras may not be identical in physical performance, for example: the focal lengths are not exactly the same, so the two cameras are not completely consistent in focusing performance, which leads to the inconsistency of left and right video intelligibility, resulting in image blurring. . Secondly, there are errors in the installation alignment of the two cameras, which causes the images captured by the dual cameras to be inconsistent in the horizontal and oblique angles of the viewing angle, which leads to deviations in image processing, which ultimately leads to image superimposition.
最后， 双摄像头中各自的图像传感器存在电性能上的差异， 致使所拍摄 到的图像在亮度、 对比度、 色度、 灰阶等特性上不一致， 进而导致左右图 像出现视觉差异， 最终导致观众产生视觉眩晕、 图像模糊等现象。 Finally, the difference in electrical performance between the respective image sensors in the dual cameras causes the captured images to be inconsistent in characteristics such as brightness, contrast, chromaticity, grayscale, etc., which in turn causes visual differences between the left and right images, ultimately leading to visual perception of the viewer. Dizziness, blurred images, etc.
图 1为申请号为 200910104853.9的中国专利 《一种立体摄像装置及方 法》 的摘要附图， 该专利公开了一种立体摄像装置， 用精密光学成像结构 来保证光路上的一致性， 仅用一个图像传感器来接收两路图像的技术， 但 是， 从图 1中看出， 该专利存在重要技术缺陷， 主要表现在： 1 is a summary drawing of a Chinese patent "A Stereo Camera Device and Method" of Application No. 200910104853.9, which discloses a stereo camera device that uses a precision optical imaging structure to ensure uniformity on the optical path, using only one The technique of image sensor to receive two-way image, however, as seen in Figure 1, the patent has important technical defects, mainly in:
首先， 第一光学成像透镜组 111、 第二光学成像透镜组 112与图像传感 器 120 的光路距离较远。 当拍摄远景时， 根据透镜成像规则， 一般要求光 学成像透镜组与图像传感器的光路距离较近， 否则会成像模糊， 因此， 该 专利阐述的装置及方法， 无法拍摄远景； First, the optical paths of the first optical imaging lens group 111, the second optical imaging lens group 112, and the image sensor 120 are far apart. When shooting a distant view, according to the lens imaging rule, it is generally required that the optical imaging lens group and the image sensor have a relatively close optical path, otherwise the image will be blurred. Therefore, the device and method described in the patent cannot capture the distant view;
其次，由于物体发出的每束光线中所有的光线只有经过平面镜相同角度 的反射后才可以成像， 该专利未充分披露第一平面反射镜 114、 第二平面反 射镜 115与第三反射镜 113的镜面的位置存在一定关系的技术细节， 如此， 可能会造成无法在图像传感器 120上成像， 从而根本无法实现拍摄的目的。 发明内容 Secondly, since all the light in each of the rays emitted by the object can be imaged only after being reflected by the plane mirror at the same angle, the patent does not fully disclose the first planar mirror 114, the second planar mirror 115 and the third mirror 113. There is a certain technical detail in the position of the mirror, which may result in the inability to image on the image sensor 120, so that the purpose of shooting cannot be achieved at all.
