Abstract

The invention discloses a method of manufacturing and displaying a three-dimensional image. The method comprises the following steps: combining two two-dimensional images into a three-dimensional image using a three-dimensional image combining algorithm, acquiring optical field distribution of the three-dimensional image based on light intensity of the three-dimensional image and depth distance, generating a light intensity type or phase type computer generated hologram of the light intensity of the three-dimensional image, controlling voltage of liquid crystal dot matrixes according to light intensity or phase of pixel points of the light intensity type or phase type computer generated hologram, and displaying the three-dimensional images by the liquid crystal dot matrixes using light beams shining the liquid crystal dot matrixes. The method can use an existing device to acquire a two-dimensional image simply, and meet the needs that material objects need to be recorded by holographic records in an optical holographic method. Due to the fact that the holographic method is used for reproducing the three-dimensional image, and the reproduced three-dimensional image is similar to a real three-dimensional image which can be observed by human eyes, so observers can observe the three-dimensional image conveniently without wearing any special glasses, and the problems of manufacturing and display of the three-dimensional image are solved effectively.

Description

technical field [0001] The invention relates to a method for making and displaying three-dimensional images. Background technique [0002] The three-dimensional or three-dimensional objects observed by human eyes in nature not only have size and brightness information, but also have distance information from human eyes. Two binoculars are similar to two cameras in fixed relative positions. At any moment, two two-dimensional images with parallax can be obtained at the same time. These two two-dimensional images can be restored to a three-dimensional image of the real world after processing by the human brain. Such a three-dimensional image can make us feel the relationship between the front, back and distance of different objects, which is lacking in the flat image. Although flat images can also give people the feeling of distance, but this feeling is calculated based on people's daily life experience, not the result of direct observation. In order to gain an immersive feel...
