Description

Optical quasi-three-dimensional space converter and applications TECHNICAL FIELD

[0001] The present application belongs to the field of optical three-dimensional imaging, and particularly relates to an optical quasi-three-dimensional space converter and applications such as three-dimensional photographing, three-dimensional projection and three-dimensional optical processing based on the optical quasi-three-dimensional space converter. BACKGROUND

[0002] The commonly used cameras can only record two-dimensional world without distance or depth information of the third dimension. In order to obtain the distance or depth information, some auxiliary technologies are needed, such as ultrasonic ranging, laser radar ranging, infrared ranging, monocular structured light ranging and binocular ranging; the ultrasonic, laser and infrared devices calculate the distance between the measured object and the sensor by measuring the time difference between the emission and return of the emission source, which is called active method. The active method is convenient, rapid and simple in calculation, and thus is widely used in real-time control. However, the emission and receiving devices are expensive and have high cost, and environmental problems such as reflection, noise and cross are difficult to avoid, and it is difficult to realize large pixels. The monocular structured light ranging can only be used for short distance measurement, such as the structured light ranging of face distance developed to improve the accuracy of face recognition. The binocular stereo vision can accurately restore the three-dimensional information of the field of view through the parallax information of the two images provided by the left and right cameras, but the binocular vision needs to match and analyze the corresponding points of the left and right images to obtain the spatial distance information, which has large calculation workload and is easily affected by the feature point mismatching, and thus is difficult to meet the real-time requirement.

[0003] The stereoscope presents different visual angles to each eye through two slightly different images, and produces depth and stereoscopic sense. However, the modern stereoscopic movie projection technology, virtual reality stereoscopic display technology and head-mounted display need to wear glasses, which is very inconvenient. Although the naked-eye stereoscopic display technologies such as holographic display, multi-viewpoint display based on parallax barrier or cylindrical lens have been developed, the stereoscopic display is still not the three-dimensional space display mode in nature, and has high cost and poor user experience.

[0004] Light processing technology includes laser processing, ultraviolet light processing, or infrared light processing. Taking laser processing as an example, laser processing is to irradiate a laser beam to the surface of a workpiece to cut off, melt the material and change the surface properties of the object by the high energy of the laser, including laser welding, laser cutting, surface modification, laser marking, laser drilling, etc. For laser marking, the laser marking machine first moves a three-dimensional positioning mobile platform to the vicinity of the three-dimensional position measurement system to be processed, determines the position of the object to be processed (positioning subsystem), and then uses another mobile platform to drive the laser to move along the X, Y and Z axes, and makes the laser beam gather and fall on the position to be marked (processing subsystem). The positioning subsystem and the processing subsystem of the above laser processing system are carried out separately, the positioning subsystem finds the position of the object to be processed, and then the processing subsystem is operated to the corresponding position for processing. This operation causes the precision error of the positioning and processing positions.

[0005] In addition, laser treatment, which also belongs to light processing technology, is a treatment method for removing tumors by surgery or directly irradiating tumors with a laser. Laser treatment is a new method developed in the past ten years. Laser is a high-energy light beam, and a specific laser beam can cut various tissues in the human body like a sharp surgical knife. Using this laser, not only can tumor tissue be easily removed, but also has good hemostatic effect. Using high-power focused laser to directly irradiate human tissue can vaporize human tissue, mainly including tumor cells. At present, the clinical application of laser treatment in tumors mainly includes skin, head and neck, forehead, facial organs and neurology, and the treatment of internal organ tumors such as liver, lung, stomach, kidney and intestine is still in the active exploration stage. The existing laser treatment needs a doctor to first move a three-dimensional positioning mobile platform to the vicinity of the tumor position with a three-dimensional imaging device such as a computed tomography (CT) device using X-rays, and accurately position the tumor position (positioning subsystem). Then, another mobile platform is used to align the laser beam with the tumor position (processing subsystem) to remove the tumor. This method has high requirements for the positioning and processing subsystems of the entire laser treatment system. SUMMARY

[0006] The purpose of the present application is to provide an optical quasi-three-dimensional space converter and some applications, which can compress large three-dimensional space objects in nature into a large number of small two-dimensional space images, or magnify small microscopic three-dimensional space objects in nature into a large number of large two-dimensional space images.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows. The present invention provides an optical quasi-three-dimensional space converter, comprising: a zoom telephoto lens as an objective lens, used to receive light from the object side in a large three-dimensional space and image it as an intermediate real image; a short-focal-length microlens array as an eyepiece, wherein each microlens in the short-focal-length microlens array converts the intermediate real image imaged by the zoom telephoto lens into an intermediate virtual image according to the spatial angle range corresponding to each microlens; a camera lens disposed on the side of the short-focal-length microlens array, converting the intermediate virtual image into a two-dimensional real image with a fixed position in a small quasi-three-dimensional space; and an object-image distance related parameter adjuster, used to adjust the focal length of the zoom telephoto lens, the short-focal-length microlens array, the camera lens, and the relative positions between the lenses; the object-image distance related parameter includes the focal length of the zoom telephoto lens, the short-focal-length microlens array, the camera lens, and the relative position data between the lenses.

[0008] The present invention also provides a second optical quasi-three-dimensional space converter, comprising: a short-focal-length microlens array as an objective lens, wherein each microlens in the short-focal-length microlens array receives light from the object side of the small three-dimensional space according to the spatial angle range corresponding to each microlens, and images it as an intermediate real image; a zoom telephoto lens as an eyepiece, used to convert the intermediate real image imaged by the short-focal-length microlens array into an intermediate virtual image; and a camera lens disposed on the side of the zoom telephoto lens, which converts the intermediate virtual image into a two-dimensional real image with a fixed position in a large quasi-three-dimensional space.

[0009] This invention also provides a third type of optical quasi-three-dimensional real image space converter, comprising: a zoom telephoto lens as an objective lens, used to receive light from the object side in a large three-dimensional space and image it into an intermediate real image; an intermediate image horizontal flipper, used to horizontally flip the intermediate real image imaged by the zoom telephoto lens to become a flipped intermediate real image; a short-focal-length microlens array as an eyepiece, wherein each microlens in the short-focal-length microlens array converts the flipped intermediate real image into a two-dimensional real image with a fixed position in a small quasi-three-dimensional space according to the spatial angle range corresponding to each microlens; and an object-image distance related parameter adjuster, used to adjust the focal length of the zoom telephoto lens, the short-focal-length microlens array, the intermediate image horizontal flipper, and the relative position between each lens; wherein the object-image distance related parameter includes the focal length of the zoom telephoto lens, the short-focal-length microlens array, the camera lens, and the relative position data between each lens.

[0010] This invention also provides a fourth type of optical quasi-three-dimensional real image space converter, comprising: a short-focal-length microlens array as an objective lens, wherein each microlens in the short-focal-length microlens array receives light from the object side of the small three-dimensional space according to the spatial angle range corresponding to each microlens, and images it as an intermediate real image; an intermediate image horizontal flipper, used to horizontally flip the intermediate real image imaged by the short-focal-length microlens array to become a flipped intermediate real image; and a zoom telephoto lens as an eyepiece, used to convert the flipped intermediate real image into a two-dimensional real image with a fixed position in a large quasi-three-dimensional space.

[0011] In the four types of optical quasi-3D spatial converters mentioned above, the object-image distance related parameter adjuster is used to adjust the focal length of the zoom telephoto lens, the short focal length microlens array, the intermediate image horizontal flipper, the camera lens, and the relative positions between each lens. The object-image distance related parameters include the focal length of the zoom telephoto lens, the short focal length microlens array, the camera lens, and the relative position data between each lens. The number of microlenses in the short focal length microlens array is ≥2. The focal length of the zoom telephoto lens is greater than the focal length of each microlens in the short focal length microlens array. The zoom telephoto lens is a single zoom telephoto lens or a zoom telephoto lens group consisting of at least two lenses connected in series. The short focal length microlens array is a single short focal length microlens array or a short focal length microlens group array. The short focal length microlens array consists of at least two short focal length microlenses arranged in parallel, the short focal length microlens group array consists of at least two short focal length microlens groups arranged in parallel, and the short focal length microlens group consists of at least two microlenses connected in series.

[0012] This invention also discloses a three-dimensional camera, which further includes a quasi-three-dimensional sensor comprising a fixed-position two-dimensional photosensitive film and an object-image distance correlation parameter recording unit disposed on the side of a short-focal-length microlens array or a zoom telephoto lens. The two-dimensional photosensitive film captures and records two angular coordinates of a two-dimensional real image, and the object-image distance correlation parameter recording unit records a set of object-image distance correlation parameters corresponding to the object distance when capturing this two-dimensional real image, thereby obtaining the three-dimensional coordinates of the spatial object. The object-image distance correlation parameter adjuster is also used to transmit the object-image distance correlation parameters to the object-image distance correlation parameter recording unit.

[0013] The present invention also discloses a three-dimensional projector, which further includes a quasi-three-dimensional projection image source generator, which is disposed on the side of a short-throw microlens array or on the side of a zoom telephoto lens and includes a two-dimensional image source with a fixed position and an object-image distance related parameter providing unit. The quasi-three-dimensional projection image source generator rapidly projects two-dimensional light from two-dimensional image sources with different projection image distances provided by the object-image distance related parameter providing unit, and the object-image distance related parameter providing unit transmits the object-image distance related parameters to the object-image distance related parameter adjuster.

[0014] This invention also discloses a three-dimensional light processing machine, further comprising a quasi-three-dimensional light-emitting and photosensitive assembly, including a fixed-position two-dimensional light source and photosensitive film assembly and an object-image distance related parameter recording and providing unit, disposed on the side of a short-focal-length microlens array or a zoom telephoto lens. The two-dimensional photosensitive film in the two-dimensional light source and photosensitive film assembly captures and records two angular coordinates of a two-dimensional real image. The object-image distance related parameter recording and providing unit records a set of object-image distance related parameters corresponding to the object distance when capturing this two-dimensional real image. Simultaneously, the quasi-three-dimensional light-emitting and photosensitive assembly uses a large number of light-emitting units in the two-dimensional light-emitting and photosensitive film assembly to emit two-dimensional light with a projection image distance equal to the above object distance, and the shape of the object to be processed. The two-dimensional light emitted during the capture is focused onto the object being captured or the object being processed at the object distance position. The object-image distance related parameter adjuster is also used to transmit the object-image distance related parameters to the recording unit of the object-image distance related parameter recording and providing unit. The providing unit of the object-image distance related parameter recording and providing unit transmits the object-image distance related parameters to the object-image distance related parameter adjuster.

[0015] This invention also discloses a three-dimensional stereoscopic perception artificial eye based on a three-dimensional camera, which further includes an electrical signal control and processor and an object-image distance related parameter recording unit. The electrical signal control and processor and the object-image distance related parameter recording unit are also connected to an object-image distance related parameter adjuster to adjust the relative positions of the two-dimensional photosensitive film, each lens, and the object-image distance related parameters. The electrical signal control and processor and the object-image distance related parameter recording unit control the two-dimensional photosensitive film to take pictures and record images, and process the electrical signals containing the three-dimensional coordinate information of spatial objects. The electrical signal control and processor and the object-image distance related parameter recording unit outputs electrical signals consistent with the signal reception rules of the optic nerve of the eye to the optic nerve of the eye. The zoom telephoto lens is equivalent to an artificial cornea and lens, and the intermediate image horizontal flipper, short focal length microlens array, two-dimensional photosensitive film, and electrical signal control and processor and the object-image distance related parameter recording unit are equivalent to an artificial retina.

[0016] This invention also discloses a laser therapy device based on a three-dimensional optical processing machine. It employs a two-dimensional laser + photosensitive composite sheet composed of a large number of cross-arranged laser units and photosensitive units as a two-dimensional light source + photosensitive sheet assembly. An infrared light source that is partially transparent to human tissue is used to irradiate the area where the cancerous tumor is located, causing the cancerous tumor to scatter light. The numerous two-dimensional photosensitive units in the two-dimensional laser + photosensitive composite sheet capture and record the two angular coordinates of the two-dimensional real image of the cancerous tumor. A set of object-image distance related parameters is recorded by the object-image distance recording and providing unit records the corresponding object distance when capturing the two-dimensional real image of the cancerous tumor. Simultaneously with the capture and recording, the numerous laser units in the two-dimensional laser + photosensitive composite sheet send two-dimensional lasers with the same projected image distance as the above object distance, showing the edge shape of the cancerous tumor tissue to be removed, or the shape of blood vessels inside or outside the cancerous tumor that need to be sintered and blocked. The two-dimensional lasers sent simultaneously with the capture are focused on the object distance position of the edge of the captured cancerous tumor tissue or the object distance position of the blood vessels inside or outside the cancerous tumor. The two-dimensional laser sheet and the photosensitive sheet can be separate components. In this case, the wavelength division multiplexer is used to separate the infrared light for photography that reaches the two-dimensional photosensitive sheet from the laser light for laser therapy emitted from the two-dimensional laser sheet.

[0017] The optical quasi-3D spatial converter of this invention can compress large three-dimensional objects in nature into a large number of small, fixed-position two-dimensional images, or magnify small, microscopic three-dimensional objects in nature into a large number of large, fixed-position two-dimensional images. The resulting fixed-position two-dimensional images are real images, each with its own specific object-image distance parameters related to the object distance of the corresponding three-dimensional object. Because the short-focal-length microlenses are arranged in a parallel array, the optical quasi-3D spatial converter of this invention can provide a wide field of view. The size of the images compressed or magnified by the quasi-3D spatial converter is suitable for wide-field-of-view 3D cameras, wide-field-of-view naked-eye 3D real-image projectors, 3D optical processing machines that synchronize 3D photography and optical processing, artificial eyes, etc. Since the quasi-3D spatial conversion yields two-dimensional real images, and the image positions are fixed, these applications are technically easy to implement.

[0018] The optical quasi-3D spatial converter described in this invention can be applied to 3D optical processing machines. The motion positioning subsystem used for 3D object imaging and the motion positioning subsystem used for optical processing are the same, thus eliminating the alignment errors between the two systems and achieving high processing position accuracy. This 3D optical processing machine can simultaneously activate the 2D light source of the optical processing subsystem while the 3D camera is positioned to the workpiece, enabling 3D optical processing (such as 3D cutting, welding, repair, scorching, etc.) and improving processing efficiency.

[0019] Simultaneously, the 3D optical processing machine can be applied to laser tumor resection. A tumor can be viewed as a group of point-like tumor fragments (tumor points). When the photosensitive unit / image point is located at part or all of this group of tumor points, the laser unit adjacent to the photosensitive unit / image point in 3D localization, or the laser unit on the 2D light-emitting sheet corresponding to the image point position, emits laser light. The tumor points and the image points received by the photosensitive unit are very close, forming a one-to-one correspondence. The laser emitted near an image point can be focused onto the corresponding tumor point, thereby achieving the purpose of tumor resection. This 3D optical processing machine only requires a photographic positioning and moving platform; no additional laser irradiation alignment platform is needed. Because the photographic positioning and moving platform can have microscopic magnification positioning capabilities, its positioning accuracy can be very high. Therefore, the laser tumor resection positioning accuracy of this 3D optical processing machine is also very high.

[0020] 3D optical processing machines can also be used in 3D laser welding technology. Laser welding is a highly efficient welding method that uses a high-energy-density laser beam as a heat source. Laser welding machines are equipped with microscopes and CCD display subsystems for easy workpiece positioning and welding effect inspection. First, the workpiece is positioned using a microscope, and then the laser welding head is moved to the positioning point for laser welding. Laser welding requires that the laser beam's position on the workpiece not deviate significantly. If the laser beam is not aligned with the weld point, welding defects are easily caused. 3D optical processing machines can emit laser light simultaneously with the photosensitive unit positioning the workpiece at the welding location, achieving precise alignment for welding. This eliminates the need to move the laser processing subsystem after the positioning subsystem has located the workpiece, improving welding accuracy. Attached Figure Description

[0047] Example 1: This invention discloses an optical quasi-3D space converter, suitable for conversion between large 3D space and small quasi-3D space, as shown in Figure 1. Specifically, it includes: a zoom telephoto lens as the objective lens, used to receive light from the object side of the large 3D space and image it as an intermediate real image; a short-focal-length microlens array as the eyepiece, where each microlens in the array converts the intermediate real image imaged by the zoom telephoto lens into an intermediate virtual image according to the spatial angle range corresponding to each microlens; a camera lens positioned on the side of the short-focal-length microlens array, converting the intermediate virtual image into a fixed-position two-dimensional real image in the small quasi-3D space; and an object-image distance related parameter adjuster, used to adjust the focal lengths of the zoom telephoto lens, the short-focal-length microlens array, and the camera lens, as well as the relative positions between the lenses, so that 3D objects at different object distances are clearly imaged on a fixed-position two-dimensional real image at a fixed image distance; thus completing the conversion between large 3D space and small quasi-3D space. The object-image distance related parameters include the focal lengths of the zoom telephoto lens, the short-focal-length microlens array, and the camera lens, as well as their relative position data.

[0048] The focal length F0 of the zoom telephoto lens is greater than the focal length f of each microlens in the short focal length microlens array. i The short-focal-length microlens array has at least two microlenses, and the focal lengths of the individual microlenses in the array can be the same or different. The focal length f of each microlens in the short-focal-length microlens array is... i For fixed focal length or variable focal length.

[0049] The zoom telephoto lens is a single zoom telephoto lens or a zoom telephoto lens group consisting of at least two lenses connected in series. The short focal length microlens array is a short focal length microlens array or a short focal length microlens group array. The short focal length microlens array consists of at least two short focal length microlenses arranged in parallel. The short focal length microlens group array consists of at least two short focal length microlens groups arranged in parallel. The short focal length microlens group consists of at least two microlenses connected in series.

[0050] The object-image distance related parameter adjuster can adjust the relative position such as up and down, left and right, forward and backward, and rotation, and can also transform the same three-dimensional object space two or more times to compensate for the lack of optical function of the gap part that does not participate in imaging and the edge part of the microlens with poor imaging quality in the short focal length microlens array.

[0051] The focal planes of each microlens in the short focal length microlens array can all coincide with the focal plane of the zoom telephoto lens, or partially coincide with it and partially lie to the left of the focal plane of the zoom telephoto lens (intersecting within the focal planes), or all lie to the left of the focal plane of the zoom telephoto lens (intersecting within the focal planes).

[0052] The large three-dimensional object space within the object angle range Δa (Δa = a2 - a1) from a1 to a2 is reduced to a three-dimensional virtual image space within the image angle range Δβ (Δβ = β2 - β1) from β1 to β2 by this optical quasi-three-dimensional space converter. Δa and Δβ can be equal or unequal. The reduction factor from object to image size is related to the focal length ratio F0 / f. i Related: F0 / f i The larger the value, the greater the reduction ratio. A large object angle range 'a' can be divided into multiple smaller object angle ranges 'Δa'. i Each Δa i The three-dimensional object within is converted by the quasi-3D space converter into a tiny image angle range Δβ within the short focal length microlens. i A three-dimensional virtual image within the space. Multiple tiny image angle ranges Δβ i The three-dimensional virtual images are merged into a large image angle range β, which serves as the second intermediate three-dimensional virtual image.

[0053] Example 2: This invention discloses an optical quasi-3D space converter. Unlike Example 1, this example is applicable to the conversion between small 3D space and large quasi-3D space, as shown in Figure 2. The objective lens is a short-focal-length microlens array. Each microlens in the short-focal-length microlens array receives light from the object side of the small 3D space according to the spatial angle range corresponding to each microlens, forming an intermediate real image. The eyepiece is a zoom telephoto lens, which is used to convert the intermediate real image formed by the short-focal-length microlens array into an intermediate virtual image. The camera lens is set on the side of the zoom telephoto lens to convert the intermediate virtual image into a fixed-position two-dimensional real image in the large quasi-3D space.

[0054] Example 3: This invention discloses an optical quasi-three-dimensional real image space converter. Unlike Example 1, as shown in Figure 3, it further includes an intermediate image horizontal flipper, used to horizontally flip the intermediate real image formed by the zoom telephoto lens to become a flipped intermediate real image; a short-focal-length microlens array as an eyepiece, where each microlens in the short-focal-length microlens array converts the flipped intermediate real image into a two-dimensional real image with a fixed position in a small quasi-three-dimensional space according to the spatial angle range corresponding to each microlens; and an object-image distance related parameter adjuster, used to adjust the focal length of the zoom telephoto lens, the intermediate image horizontal flipper, the short-focal-length microlens array, and the relative positions between each lens.

[0055] Example 4: This invention discloses an optical quasi-three-dimensional space converter, which differs from Example 2 in that, as shown in Figure 4, it further includes an intermediate image horizontal flipper, used to horizontally flip the intermediate real image imaged by the short focal length microlens array to become a flipped intermediate real image; a zoom telephoto lens as an eyepiece, used to convert the flipped intermediate real image into a two-dimensional real image with a fixed position in a large quasi-three-dimensional space; and an object-image distance related parameter adjuster, used to adjust the focal length of the zoom telephoto lens, the intermediate image horizontal flipper, the short focal length microlens array, and the relative positions between each lens.

[0056] Example 5: As shown in Figure 5, this is a 3D camera based on Figure 1, which also includes a quasi-3D sensor with a fixed position of a two-dimensional photosensitive film and an object-image distance related parameter recording unit disposed on the side of the short focal length microlens array. The two-dimensional photosensitive film records two angular coordinates of the two-dimensional real image, and the object-image distance related parameter recording unit records a set of object-image distance related parameters corresponding to the object distance (third dimension) when the two-dimensional real image is captured, thereby obtaining the three-dimensional coordinates of the spatial object; the object-image distance related parameter adjuster is also used to transmit the object-image distance related parameters to the object-image distance related parameter recording unit.

[0057] In specific implementation, as shown in Figure 18, a zoom telephoto convex lens (or a zoom telephoto convex lens group) is used as the zoom telephoto lens, a short focal length micro convex lens array (or a short focal length micro convex lens group array) is used as the short focal length micro lens array, a convex lens (or convex lens group) is used as the camera lens in the quasi-3D sensor, and an arc-shaped two-dimensional photosensitive film composed of a large number of photosensitive units is used as a fixed-position two-dimensional photosensitive film in the quasi-3D sensor. The two-dimensional photosensitive film is used to capture and record the two angular coordinates (two dimensions) of the two-dimensional real image. The object-image distance related parameter recording unit records a set of object-image distance related parameters corresponding to the object distance of the three-dimensional object (third dimension) when this two-dimensional real image is captured, thus obtaining the three-dimensional coordinates of the three-dimensional object. The azimuth angle of the two-dimensional image represents the azimuth angle of the location of the three-dimensional object (or three-dimensional image), and one azimuth angle has two angular coordinates. The object-image distance related parameters represent the object distance (or image distance) of the three-dimensional object (or three-dimensional image), thereby realizing the conversion from three-dimensional coordinates to quasi-3D coordinates.

[0058] The projection azimuth and image distance of the two-dimensional light from each two-dimensional image source or two-dimensional light source correspond to a set of object-image distance related parameters. If the two-dimensional image source is obtained by using the device shown in Figure 5, the projected image distance of each two-dimensional image source can use the corresponding set of object-image distance related parameters used during shooting. If the set of object-image distance related parameters used for shooting is different from the set of object-image distance related parameters used for projection, they have a corresponding calculation relationship. If the two-dimensional image source is generated by a computer, the projected image distance of each two-dimensional image source corresponds to a set of object-image distance related parameters required for this three-dimensional real image.

[0059] Example 6: As shown in Figure 6, this is a 3D real image projector based on Figure 1. It also includes a quasi-3D projection image source generator, located on the side of the short-throw microlens array, comprising a fixed-position 2D image source and an object-image distance related parameter providing unit. The quasi-3D projection image source generator rapidly projects 2D light from the fixed-position 2D image source with different projection image distances provided by the object-image distance related parameter providing unit, projecting a 3D real image in the air for naked-eye viewing. Different projection image distances are determined by the system's object-image distance related parameters, i.e., by the focal length of each lens and the position between the lenses. If the same fixed image distance used when capturing the 2D image source is used as the fixed object distance of the image source for projection, the object-image distance related parameters of the capturing system and the projection system can be the same or different (there is a calculation relationship between them: when they are the same, the size of the 3D object during capture is the same as the size of the 3D real image during projection; when they are different, the size of the 3D object during capture is different from the size of the 3D real image during projection). If different fixed image distances when shooting a two-dimensional image source are used as the fixed object distance of the image source for projection, the object-image distance related parameters of the shooting system and the projection system can be the same or different (there is a calculation relationship between them: when they are the same, the size of the three-dimensional object when shooting is different from the size of the three-dimensional real image when projecting; when they are different, under a certain calculation relationship, the size of the three-dimensional object when shooting is different from the size of the three-dimensional real image when projecting is the same).

[0060] In practical implementation, as shown in Figure 19, a zoom telephoto convex lens (or a zoom telephoto convex lens group) is used as the zoom telephoto lens, a short-focal-length micro-convex lens array (or a short-focal-length micro-convex lens group array) is used as the short-focal-length micro-lens array, and a convex lens (or convex lens group) is used as the camera lens in the quasi-3D projection image source generator. An arc-shaped two-dimensional image emitting sheet composed of numerous light-emitting units serves as a fixed-position two-dimensional image source in the quasi-3D projection image source generator. By rapidly projecting two-dimensional light from the two-dimensional image emitting sheet with different projection image distances, provided by the object-image distance related parameter providing unit, into the air, a three-dimensional real image can be formed for naked-eye viewing. The different projection image distances are determined by the system's object-image distance related parameters.

[0061] Example 7: As shown in Figure 7, this is a three-dimensional light processing machine based on Figure 1. It further includes a quasi-three-dimensional light-emitting and photosensitive assembly, located on the side of the short-focal-length microlens array, comprising a fixed-position two-dimensional light source and photosensitive film assembly, and an object-image distance related parameter recording and providing unit. The two-dimensional photosensitive film in the two-dimensional light source and photosensitive film assembly captures and records two angular coordinates of a two-dimensional real image. The object-image distance related parameter recording and providing unit records a set of object-image distance related parameters corresponding to the object distance (third dimension) when capturing this two-dimensional real image. Simultaneously, the quasi-three-dimensional light-emitting and photosensitive assembly uses numerous light-emitting units in the two-dimensional light-emitting and photosensitive film assembly to emit two-dimensional light with a projection image distance equal to the above object distance, representing the shape of the object to be processed. The two-dimensional light emitted during the capture is focused onto the object being captured or the object being processed. The object-image distance related parameter adjuster is also used to transmit the object-image distance related parameters to the recording unit of the object-image distance related parameter recording and providing unit; the providing unit of the object-image distance related parameter recording and providing unit transmits the object-image distance related parameters to the object-image distance related parameter adjuster.

[0062] In specific implementation, as shown in Figure 20: a zoom telephoto convex lens (or a zoom telephoto convex lens group) is used as the zoom telephoto lens, a short focal length micro-convex lens array (or a short focal length micro-convex lens group array) is used as the short focal length micro-lens array, and a micro-convex lens array (or a micro-convex lens group array) is used as the camera lens in the quasi-three-dimensional light-emitting + photosensitive assembly. An arc-shaped two-dimensional light-emitting + photosensitive assembly composed of a large number of cross-arranged photosensitive and light-emitting units serves as a fixed-position two-dimensional light source + photosensitive film assembly within the quasi-three-dimensional light-emitting + photosensitive assembly. The numerous two-dimensional photosensitive units in the two-dimensional light-emitting + photosensitive assembly record the two angular coordinates of the two-dimensional real image, and record and provide a set of object-image distance related parameters for the corresponding object distance (third dimension) when capturing this two-dimensional real image. Simultaneously, the numerous light-emitting units in the two-dimensional light-emitting + photosensitive assembly emit two-dimensional light with a projection image distance equal to the above object distance. The two-dimensional light emitted during shooting is focused onto the object distance of the photographed object. The light intensity density at the focused position is much higher than at other positions. When the light intensity density at the focused point reaches the light intensity density threshold required for the optical processing of the workpiece, optical processing of the workpiece can be completed. By sending multiple two-dimensional lights with corresponding different object distances that reach the optical processing intensity density threshold, three-dimensional optical processing at various depths can be achieved.

The two-dimensional photosensitive film captures and records two angular coordinates of a two-dimensional real image, and the object-image distance correlation parameter recording unit records a set of object-image distance correlation parameters corresponding to the object distance (third dimension) when capturing this two-dimensional real image, thus obtaining the three-dimensional coordinates of the spatial object.

The object-image distance related parameter providing unit transmits the object-image distance related parameters to the object-image distance related parameter adjuster. The quasi-3D projection image source generator rapidly projects 2D light from the 2D image source with different projection image distances provided by the object-image distance related parameter providing unit, projecting a 3D real image in the air for naked-eye viewing. Different projection image distances are determined by the system's object-image distance related parameters.

The object-image distance related parameter recording and providing unit records a set of object-image distance related parameters corresponding to the object distance (third dimension) when capturing this two-dimensional real image. Simultaneously, the quasi-three-dimensional light-emitting and photosensitive assembly uses numerous light-emitting units in the two-dimensional light-emitting and photosensitive assembly to emit two-dimensional light with a projection image distance equal to the above object distance, representing the shape of the object to be processed. The two-dimensional light emitted during the capture is focused onto the object being captured or the object being processed. The object-image distance related parameter adjuster is also used to transmit the object-image distance related parameters to the recording unit of the object-image distance related parameter recording and providing unit; the providing unit of the object-image distance related parameter recording and providing unit transmits the object-image distance related parameters to the object-image distance related parameter adjuster.

[0066] Example 11: A three-dimensional camera based on Figure 3, as shown in Figure 11, further includes a quasi-three-dimensional sensor containing a two-dimensional photosensitive film with a fixed position and an object-image distance related parameter recording unit. The two-dimensional photosensitive film records two angular coordinates of the two-dimensional real image, and the object-image distance related parameter recording unit records a set of object-image distance related parameters corresponding to the object distance (third dimension) when the two-dimensional real image is captured, thus obtaining the three-dimensional coordinates of the spatial object; the object-image distance related parameter adjuster is used to adjust the relative positions between the two-dimensional photosensitive film, the zoom telephoto lens, the intermediate image horizontal flipper, and the short focal length microlens array, and to adjust the object-image distance related parameters.

[0067] In specific implementation, as shown in Figure 21, a zoom telephoto convex lens (or a zoom telephoto convex lens group) is used as the zoom telephoto lens, a fan-shaped array of columnar self-focusing microlenses is used as the intermediate image horizontal flipper (this intermediate image horizontal flipper also includes the intermediate image magnification function, and the magnification is fixed), a short-focus micro-convex lens array (or a short-focus micro-convex lens group array) is used as the short-focus microlens array, and an arc-shaped two-dimensional photosensitive film composed of a large number of photosensitive units is used as a fixed-position two-dimensional photosensitive film in the quasi-three-dimensional photosensitive sensor. The two-dimensional photosensitive film is used to photograph and record the two angular coordinates (two dimensions) of the two-dimensional real image, and the object-image distance related parameter recording unit records a set of object-image distance related parameters corresponding to the object distance of the three-dimensional object in the three-dimensional space when this two-dimensional real image was photographed (third dimension), thus obtaining the three-dimensional coordinates of the three-dimensional object.

[0068] Example 12: A three-dimensional stereoscopic sensing artificial eye based on Figure 11, as shown in Figure 17, further includes an electrical signal control and processor and an object-image distance related parameter recording unit; the electrical signal control and processor and object-image distance related parameter recording unit are also connected to an object-image distance related parameter adjuster to adjust the relative positions of the two-dimensional photosensitive film, each lens, and the object-image distance related parameters; the electrical signal control and processor and object-image distance related parameter recording unit control the two-dimensional photosensitive film to take pictures and record, and process the electrical signal containing the three-dimensional coordinate information of the spatial object; the electrical signal control and processor and object-image distance related parameter recording unit outputs an electrical signal consistent with the signal reception rules of the optic nerve of the eye to the optic nerve of the eye, wherein the zoom telephoto lens is equivalent to the artificial cornea and lens, and the intermediate image horizontal flipper, short focal length microlens array, two-dimensional photosensitive film, and electrical signal control and processor and object-image distance related parameter recording unit are equivalent to the artificial retina.

[0069] In specific implementation, as shown in Figure 26, a zoom telephoto convex lens (or a zoom telephoto convex lens group) is used as the zoom telephoto lens, a fan-shaped columnar self-focusing microlens array is used as the intermediate image horizontal flipper (the intermediate image horizontal flipper here also includes the intermediate image magnification function, and the magnification is fixed), a short focal length micro convex lens array (or a short focal length micro convex lens group array) is used as the short focal length microlens array, and an arc-shaped two-dimensional photosensitive film composed of a large number of photosensitive units is used as a fixed-position two-dimensional photosensitive film in the quasi-three-dimensional photosensitive film. The two-dimensional photosensitive film is used to take pictures and record the two angular coordinates (two dimensions) of the two-dimensional real image. The electrical signal control and processor and the object-image distance related parameter recording unit record a set of object-image distance related parameters corresponding to the object distance (third dimension) of the three-dimensional spatial object when the two-dimensional real image is captured, so as to obtain the three-dimensional coordinates of the three-dimensional spatial object.

[0070] On the far right of the artificial eye, an electrical signal control and processor, along with a recording unit for object-image distance correlation parameters, is connected to a zoom telephoto lens, a two-dimensional photosensitive film, and an object-image distance correlation parameter adjuster. This control unit manages the relative positions of the two-dimensional photosensitive film and the lenses, as well as the recording process of the two-dimensional photosensitive film. It also processes the electrical signals containing three-dimensional spatial information output from the two-dimensional photosensitive film, the zoom telephoto lens, and the object-image distance correlation parameter adjuster. The electrical signals processed and output by the electrical signal control and processor, along with the recording unit for object-image distance correlation parameters, are consistent with the electrical signals received by the optic nerve of the eye. The processed electrical signals are then transmitted to numerous optic nerves of the eye through a large number of electrical connections.

[0071] The zoom telephoto lens is equivalent to an artificial cornea and lens, while the self-focusing microlens array, short-focus microconvex lens array, two-dimensional photosensitive film, electrical signal control and processor, and object-image distance related parameter recording unit are equivalent to an artificial retina.

[0072] In practical use, the artificial cornea and lens of the artificial eye (as shown in Figures 17 and 26) can be implanted to replace the cornea and lens of one eye; or the artificial retina can be implanted to replace the retina of one eye; or the entire artificial eye can be implanted to replace the cornea, lens, and retina of one eye, which can bring good news to blind patients.

[0073] Example 13: A three-dimensional real image projector based on Figure 3, as shown in Figure 12, further includes a quasi-three-dimensional projection image source generator with a fixed position of a two-dimensional image source and an object-image distance related parameter providing unit, which is set on the side of the intermediate image horizontal flipper. The quasi-three-dimensional projection image source generator quickly projects two-dimensional light from two-dimensional image sources with different projection image distances provided by the object-image distance related parameter providing unit.

[0074] In specific implementation, as shown in Figure 22, a zoom telephoto convex lens (or a zoom telephoto convex lens group) is used as the zoom telephoto lens; a fan-shaped array of columnar self-focusing microlenses serves as the intermediate image horizontal flipper (this intermediate image horizontal flipper also includes an intermediate image magnification function, with a fixed magnification); a short-focal-length micro-convex lens array (or a short-focal-length micro-convex lens group array) serves as the short-focal-length microlens array; and an arc-shaped two-dimensional image emitting sheet composed of numerous light-emitting units serves as the two-dimensional image source in the quasi-three-dimensional projection image source generator. By rapidly projecting two-dimensional light from the two-dimensional image emitting sheet with different projection image distances provided by the object-image distance related parameter providing unit in the air, a three-dimensional real image can be formed in the air for naked-eye viewing. The different projection image distances are determined by the system's object-image distance related parameters.

[0075] Example 14: A three-dimensional light processing machine based on Figure 3, as shown in Figure 13, further includes a quasi-three-dimensional light-emitting + photosensitive assembly with a fixed position of a two-dimensional light source + photosensitive film assembly and an object-image distance related parameter recording and providing unit, located on the side of the intermediate image horizontal flipper. The two-dimensional photosensitive film in the two-dimensional light source + photosensitive film assembly takes pictures and records two angular coordinates of the two-dimensional real image. The object-image distance related parameter recording and providing unit records a set of object-image distance related parameters corresponding to the object distance (third dimension) when this two-dimensional real image is taken. At the same time, the quasi-three-dimensional light-emitting + photosensitive assembly uses a large number of light-emitting units in the two-dimensional light-emitting + photosensitive assembly to send two-dimensional light with the same projection image distance as the above object distance, which has the shape of the object to be processed. The two-dimensional light sent at the same time as taking pictures is focused on the object being photographed or the object distance position of the object being processed.

[0076] In specific implementation, as shown in Figure 23, a zoom telephoto convex lens (or a zoom telephoto convex lens group) is used as the zoom telephoto lens, a fan-shaped array of columnar self-focusing microlenses is used as the intermediate image horizontal flipper (the intermediate image horizontal flipper here also includes the intermediate image magnification function, and the magnification is fixed), a short-focus micro-convex lens array (or a short-focus micro-convex lens group array) is used as the short-focus microlens array, and an arc-shaped two-dimensional light-emitting + photosensitive combination sheet composed of a large number of cross-arranged photosensitive units and light-emitting units is used as a fixed-position two-dimensional light source + photosensitive film combination in the quasi-three-dimensional light-emitting + photosensitive combination. The large number of two-dimensional photosensitive units in the two-dimensional light-emitting + photosensitive combination sheet are used to photograph and record the two angular coordinates of the two-dimensional real image, and a set of object-image distance related parameters are recorded and provided by the unit recording the corresponding object distance (third dimension) when this two-dimensional real image is photographed; at the same time, the large number of light-emitting units in the two-dimensional light-emitting + photosensitive combination sheet send two-dimensional light with the same projected image distance as the above object distance, which has the shape of the object to be processed. Simultaneously with the shooting, two-dimensional light is focused onto the object being photographed or processed at a distance from the subject. The light intensity density at the focused point is much higher than at other points. When the light intensity density at the focused point reaches the light intensity density threshold required for the optical processing of the object, the optical processing of the object can be completed. By sending multiple two-dimensional lights at different object distances, each reaching the optical processing intensity density threshold, three-dimensional optical processing at various depths can be achieved.

[0077] Example 15: A three-dimensional camera based on Figure 4, as shown in Figure 14, further includes a quasi-three-dimensional sensor with a fixed two-dimensional photosensitive film and an object-image distance related parameter recording unit disposed on the side of the zoom telephoto lens. The two-dimensional photosensitive film records two angular coordinates of the two-dimensional real image, and the object-image distance related parameter recording unit records a set of object-image distance related parameters corresponding to the object distance (third dimension) when the two-dimensional real image is captured, thus obtaining the three-dimensional coordinates of the spatial object; the object-image distance related parameter adjuster is used to adjust the relative positions between the two-dimensional photosensitive film, the zoom telephoto lens, the intermediate image horizontal flipper, and the short focal length microlens array, and to adjust the object-image distance related parameters.

[0078] Example 16: A three-dimensional real image projector based on Figure 4, as shown in Figure 15, further includes a quasi-three-dimensional projection image source generator with a fixed position of a two-dimensional image source and an object-image distance related parameter providing unit disposed on the side of the zoom telephoto lens. The quasi-three-dimensional projection image source generator quickly projects two-dimensional light from two-dimensional image sources with different projection image distances provided by the object-image distance related parameter providing unit.

[0079] Example 17: A three-dimensional light processing machine based on Figure 4, as shown in Figure 16, further includes a quasi-three-dimensional light-emitting and photosensitive assembly with a fixed position, comprising a two-dimensional light source and photosensitive film assembly and an object-image distance related parameter recording and providing unit, located on the side of the zoom telephoto lens. The two-dimensional photosensitive film in the two-dimensional light source and photosensitive film assembly takes pictures and records two angular coordinates of the two-dimensional real image. The object-image distance related parameter recording and providing unit records a set of object-image distance related parameters corresponding to the object distance (third dimension) when this two-dimensional real image is taken. At the same time, the quasi-three-dimensional light-emitting and photosensitive assembly uses a large number of light-emitting units in the two-dimensional light-emitting and photosensitive assembly to send two-dimensional light with the same projection image distance as the above object distance, which has the shape of the object to be processed. The two-dimensional light sent at the same time as taking pictures is focused on the object being photographed or the object being processed.

[0080] Example 18: As shown in Figure 24, this is a specific embodiment of a laser therapy device for cancer tumors based on the three-dimensional optical processing machine shown in Figure 16 (which cuts the tumor edge tissue or blocks blood vessels inside (or outside) the tumor). A zoom telephoto lens (or a zoom telephoto lens group) is used as the zoom telephoto lens; a fan-shaped array of columnar self-focusing microlenses is used as the intermediate image horizontal flipper (this intermediate image horizontal flipper also includes an intermediate image reduction function, with a fixed reduction magnification); a short-focus micro-convex lens array (or a short-focus micro-convex lens group array) is used as the short-focus microlens array; and an arc-shaped two-dimensional laser + photosensitive composite sheet composed of a large number of cross-arranged laser units and photosensitive units serves as a fixed-position two-dimensional light source + photosensitive film composite within the quasi-three-dimensional light-emitting + photosensitive composite. An infrared light source, partially transparent to human tissue, illuminates the area containing the cancerous tumor, causing the tumor to scatter light. A large number of two-dimensional photosensitive units within a two-dimensional laser + photosensitive film capture and record the two angular coordinates of a two-dimensional real image of the tumor. A set of object-image distance related parameters is recorded, along with the corresponding object distance (third dimension) recorded by the unit. Simultaneously, the numerous laser units within the two-dimensional laser + photosensitive film emit two-dimensional laser beams with the same projected image distance as the object distance, depicting the edge shape of the cancerous tumor tissue to be removed, or the shape of blood vessels within (or outside) the cancerous tumor to be sintered and blocked. The emitted two-dimensional laser is focused at the object distance position of the edge of the cancerous tumor tissue or the object distance position of the blood vessels within (or outside) the cancerous tumor. The laser intensity density at the focused laser position is much higher than at other positions. When the laser intensity density at the focused laser position reaches the laser intensity density threshold required for laser processing of the cancerous tumor, laser processing of the tumor can be completed. By sending two-dimensional lasers at different distances to the edge of the corresponding cancerous tumor tissue or blood vessels inside (or outside) the cancerous tumor to reach the laser intensity density threshold, it is possible to remove cancerous tumors at various depths or to perform laser treatment on cancerous tumors that block blood vessels inside (or outside) the cancerous tumor.

[0081] Example 19: As shown in Figure 25, this is another specific embodiment of the three-dimensional optical processing machine shown in Figure 16 as a laser therapy device for cancer tumors (by cutting the edge tissue of the tumor or blocking blood vessels inside (or outside) the tumor).

[0082] The difference between Example 19 and Example 18 is that Example 19 adds a wavelength division multiplexer to the quasi-three-dimensional light-emitting + photosensitive assembly. This multiplexer separates the infrared light for photography reaching the two-dimensional photosensitive film from the laser light for laser therapy emitted from the two-dimensional laser sheet. The curved two-dimensional laser sheet and the curved two-dimensional photosensitive film in the two-dimensional light source + photosensitive film assembly are two separate components. These two separate devices can increase the density of photosensitive units in the two-dimensional photosensitive film and the density of laser units in the two-dimensional laser sheet, thereby improving the precision of three-dimensional cancer tumor location perception and the precision of three-dimensional laser treatment of cancer tumor location.

[0083] In practical applications, this invention can utilize lasers or non-laser methods, and can employ light of various wavelengths, such as visible light, infrared light, ultraviolet light, X-rays, and even electromagnetic waves (which are also a type of light). Furthermore, the light can be the object's own emission (such as its own thermal infrared light, fluorescence, etc.), or it can be reflected, scattered, or transmitted light emitted from the object when it is illuminated. For example, when using the 3D camera, one application of this invention, a color stereoscopic photograph of the object can be taken using the three primary colors of visible light (the same as those seen by the human eye); a stereoscopic photograph of the infrared light emitted from the object can be taken using infrared light; a stereoscopic photograph of the ultraviolet light emitted from the object can be taken using ultraviolet light; a stereoscopic photograph of the object can be taken using X-rays (especially useful for photographing the three-dimensional structure of the human body); and a stereoscopic photograph of the electromagnetic waves emitted from objects in space can be taken using electromagnetic waves.
