Technical Field

Background

It is well known that although we can observe images and videos of remote environments, the angle of our observation is fixed by the angle of the photographer. Just as we are looking at a landscape picture, if the close objects are sharp, then the distant scene must be blurred. One person can only see the back shadow if only shooting from the back, and cannot see the real effect of one meter if the shooting distance of the object is five meters; furthermore, the music that we listen to has been developed from mono to surround stereo effect of 5.1 channels for better enjoyment, making music enjoy more realistic and realistic. The image video only has a single picture, and although the resolution of the current video image is higher and finer, the video image is only a plane image and has no sense of depth. Although stereoscopic image and video technology is available, the real effect is not ideal and is basically calculated by computer simulation.

Drawings

Fig. 1 is a schematic view of light propagation according to an embodiment of the present invention.

Detailed Description

Embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways, which are defined and covered by the claims.

As shown in fig. 1, the present embodiment provides a holographic three-dimensional space imaging method, which includes the steps of:

s1, simultaneously imaging the targets with different distances in the same target range through the imaging objective lens 8;

s2, taking out target images with different distances formed by the imaging objective lens in a prism light splitting mode;

and S3, respectively irradiating the target images with different distances onto the corresponding sensors.

Specific examples are as follows:

s1, imaging the long-distance target 1, the middle-distance target 3 and the short-distance target 5 in the same target range through the imaging objective lens 8;

s2, taking three target images of a long-distance target 1, a middle-distance target 3 and a short-distance target 5 formed by an imaging objective lens in a prism light splitting mode;

and S3, respectively irradiating three target images of the long-distance target 1, the middle-distance target 3 and the short-distance target 5 onto corresponding sensors.

Based on the above, the target is imaged through the imaging objective lens 8, the mixed target images are separated by utilizing prism light splitting, and the images with different distances can be displayed under the cooperation of the sensor; any observation distance in the whole observation range is real and clear, and the shooting distance and angle limitation of a photographer is broken.

Based on the foregoing scheme, with reference to fig. 1, an embodiment of the present invention further provides a holographic three-dimensional space imaging device. The imaging device comprises a long-distance target 1, a medium-distance target 3, a near-distance target 5, an imaging objective 8 and a three-split prism 9 which are sequentially arranged, wherein the three-split prism 9 is positioned on the light-emitting side of the imaging objective 8, one side of the three-split prism 9 is provided with a long-distance sensor 10, the other side of the three-split prism 9 is provided with a medium-distance sensor 11, one side of the three-split prism 9, which is opposite to the other two sides, is provided with a near-distance sensor 7, the imaging objective 8 obtains the long-distance object light 2 of the long-distance target 1 and images the long-distance object light 2 to the light-emitting side of the imaging objective 8, the imaging objective 8 obtains the medium-distance object light 4 of the medium-distance target 3 and images the medium-distance object light 4 to the light-emitting side of the imaging objective 8, the imaging objective 8 obtains the near-distance object light, The images of the intermediate target 3 and the near target 5 are refracted onto the distance sensor 10, the intermediate sensor 11 and the near sensor 7, respectively.

The environment in the same target range is divided into three sections of a far target 1, a middle target 3 and a near target 5 due to different distances, and the far object light 2 of the far target 1 is converted into the near object light 2; intermediate object light 4 of the intermediate target 3; the near object light 6 of the near target 5 is simultaneously incident to the imaging objective lens 8;

the long-distance object light 2, the middle-distance object light 4 and the short-distance object light 6 are imaged behind the imaging objective lens 8 at the same time, and because the three target images are simultaneously superposed behind the imaging objective lens 8, the imaging distance of the long-distance target 1 is the closest, the imaging distance of the short-distance target 5 is the farthest, and the imaging distance of the middle-distance target 3 is between the two;

since the far, middle and near three sections of targets are imaged on the same optical axis, when the image sensor is used for picking up the image, the spatial positions are mutually influenced, and the images cannot be simultaneously acquired. A three-beam splitter prism 9 is therefore provided behind the imaging objective 8. The three-beam splitter prism 9 splits an image formed by mixing the three sections of targets into three paths of non-coaxial images with equal energy from a coaxial superposition state.

Based on this, the invention images the long-distance target 1, the middle-distance target 3 and the short-distance target 5 in the same target range through the imaging objective lens 8, the images of the long-distance target 1, the middle-distance target 3 and the short-distance target 5 after imaging are separated by the three-beam splitter prism 9, the long-distance sensor 10, the middle-distance sensor 11 and the short-distance sensor 7 outside the three-beam splitter prism 9 respectively acquire the images of the long-distance target 1, the middle-distance target 3 and the short-distance target 5, the imaging objective lens 8 is matched with the three-beam splitter prism 9, simultaneously imaging different distances of the same observation environment target range, recording the shot whole space pattern information through a sensor, the system can reproduce pictures and images at any angles of different distances and different angles in a shooting environment, so that any observation distance in the whole observation range is real and clear, and the shooting distance and angle limitation of a photographer is broken.

The distance between the long-distance sensor 10 and the trisection prism 9 is a first distance, the distance between the middle-distance sensor 11 and the trisection prism 9 is a second distance, the distance between the short-distance sensor 7 and the trisection prism 9 is a third distance, the first distance is smaller than the second distance, and the second distance is smaller than the third distance; the relative distance between the sensor and the trisection prism 9 is adjusted, and images formed by the far, middle and near three sections of targets can be acquired simultaneously.

Based on the foregoing solution, as shown in fig. 1, an embodiment of the present invention further provides a holographic stereo space imaging system, which includes a left imaging system 12 and a right imaging system 13, where the left imaging system 12 and the right imaging system 13 each include the holographic stereo space imaging apparatus according to any one of claims 1-2, and the holographic stereo space imaging apparatus includes the left imaging system 12 and the right imaging system 13, so as to ensure that video image shooting is more suitable for human observation, and ensure stereo space and distance sense of the environment; of course, the holographic three-dimensional space imaging systems are arranged in a three-axis bidirectional distribution manner, and 360-degree holographic space shooting and recording of the environmental target can be realized.
