Description

Technical Field

[0001] The present invention belongs to the field of optical three-dimensional imaging, and in particular relates to an optical quasi-three-dimensional space converter and applications such as three-dimensional photography, three-dimensional projection and three-dimensional light processing based on the optical quasi-three-dimensional space converter. Background Art

[0002] The cameras commonly used at present can only record the two-dimensional world, without the third-dimensional distance or depth information. 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. Ultrasonic, laser, infrared and other 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 the active method. The active method of ranging is convenient, fast and simple to calculate, so it has been widely used in real-time control. However, the transmitting and receiving equipment is expensive and the cost is high. In addition, environmental problems such as reflection, noise and crossover are difficult to avoid. It is difficult to achieve large pixels and it is still difficult to achieve universal applicability. 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; binocular stereo vision can restore the three-dimensional information of the field of view more accurately through the parallax information of the two images provided by the left and right cameras. However, binocular vision obtains spatial distance information and requires matching analysis of corresponding points in the left and right images, which requires a large amount of calculation workload. Binocular vision measurement is also easily affected by mismatching of feature points, making it difficult to meet real-time requirements.

[0003] Stereoscopes present different perspectives to each eye through two slightly different images, creating a sense of depth and three-dimensionality. However, modern stereoscopic film projection technology, virtual reality stereoscopic display technology, head-mounted displays, etc. all require wearing glasses, which is very inconvenient to use. Although naked-eye stereoscopic display technologies such as holographic display and multi-viewpoint display based on parallax barriers or cylindrical lenses have also been developed, stereoscopic display is still not a natural three-dimensional space display method, and it is costly and has a poor user experience.

[0004] Optical processing technologies include laser processing, ultraviolet light processing, or infrared light processing. Taking laser processing as an example, laser processing is to irradiate the surface of the workpiece with a laser beam, and use the high energy of the laser to cut, melt materials and change the surface properties of the object, including laser welding, laser cutting, surface modification, laser marking, laser drilling, etc. As for laser marking, the laser marking machine first uses a three-dimensional positioning mobile platform to move the three-dimensional position measurement system to the vicinity of the object to be processed, locates and determines the position of the object to be processed that needs to be marked (positioning subsystem), and then uses another mobile platform to drive the laser to move along the X, Y, and Z axes respectively, and makes the laser beam converge and fall to the position that needs to be marked (processing subsystem). The positioning subsystem and processing subsystem of the above laser processing system are carried out separately. The positioning subsystem first finds the position of the object to be processed, and then operates the processing subsystem to its corresponding position for processing. This operation causes errors in the accuracy of positioning and processing positions.

[0005] In addition, laser therapy, which also belongs to optical processing technology, is a treatment method that uses laser to surgically remove or directly irradiate tumors to eliminate them. Laser therapy is a new method developed in the past decade. Laser is a high-energy light beam. A specific laser beam can cut various tissues of the human body like a sharp scalpel. Using this laser, it can not only easily remove tumor tissue, but also has a 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 therapy in tumors is mainly seen in the skin, head and neck, forehead, five senses and neurology, etc. The treatment of visceral tumors such as liver, lung, stomach, kidney and intestine is still in the active exploration stage. Existing laser therapy requires doctors to first use a three-dimensional positioning mobile platform to move the three-dimensional imaging equipment, such as a computer tomography (CT) device using X-rays, to the vicinity of the tumor location, accurately locate the tumor location (positioning subsystem), and then use another mobile platform to align the laser beam with the tumor location (processing subsystem) to remove the tumor. This method requires high precision in the positioning of the entire laser treatment system and the position control of the processing subsystem. Summary of the invention

[0017] In the above four optical quasi-3D space converters, the object-image distance related parameter regulator is used to adjust the focal length of the zoom telephoto lens, the short-focus microlens array, the intermediate image horizontal flipper, the camera lens, and the relative position between each lens; the object-image distance related parameters include the focal length of the zoom telephoto lens, the short-focus microlens array, the camera lens, and the relative position data between each lens; the number of microlenses in the short-focus microlens array is ≥ 2; the focal length of the zoom telephoto lens is greater than the focal length of each microlens in the short-focus microlens array; the zoom telephoto lens is a zoom telephoto lens or a zoom telephoto lens group composed of at least two lenses connected in series.

The two-dimensional photosensitive film records two angular coordinates of a two-dimensional real image when taking pictures, and the object-image distance related parameter recording unit records a group of object-image distance related parameters corresponding to the object distance when taking the two-dimensional real image, so as to obtain the three-dimensional coordinates of the spatial object; the object-image distance related parameter regulator is also used to transmit the object-image distance related parameters to the object-image distance related parameter recording unit.

[0019] The present invention also discloses a three-dimensional projector, which also includes a quasi-three-dimensional projection picture source generator arranged on the side of a short-focus microlens array or a zoom telephoto lens, and includes a fixed-position two-dimensional picture source and an object-image distance related parameter providing unit. The quasi-three-dimensional projection picture source generator quickly projects two-dimensional light of a two-dimensional picture source 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 regulator.

[0020] The present invention also discloses a three-dimensional optical processing machine, which also includes a quasi-three-dimensional luminous + photosensitive combination body arranged on the side of a short-focus microlens array or a zoom telephoto lens, and includes a two-dimensional light source + photosensitive film combination with a fixed position, and an object-image distance related parameter recording and providing unit. The two-dimensional photosensitive film in the two-dimensional light source + photosensitive film combination records two angle coordinates of a two-dimensional real image by photographing, and the object-image distance related parameter recording and providing unit records a group of object-image distance related parameters corresponding to the object distance when photographing the two-dimensional real image; at the same time, the quasi-three-dimensional luminous + photosensitive combination body uses a large number of luminous units in the two-dimensional luminous + photosensitive combination film to send two-dimensional light with a projection image distance that is the same as the above object distance and in the shape of an object to be processed. The two-dimensional light sent while photographing is focused to the position of the object distance of the photographed object or the object to be processed, and the object-image distance related parameter regulator 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 regulator.

[0021] The present invention also discloses an artificial eye with three-dimensional stereoscopic perception formed on the basis of a three-dimensional camera, which also includes an electrical signal control and processor and a recording unit for object-image distance related parameters; the electrical signal control and processor and the recording unit for object-image distance related parameters are also connected to an adjuster for object-image distance related parameters to adjust the two-dimensional photosensitive film, the relative positions between the lenses and the parameters related to the object-image distance; the electrical signal control and processor and the recording unit for object-image distance related parameters control the two-dimensional photosensitive film to take pictures and record, and process the electrical signal containing the three-dimensional coordinate information of the space object, the electrical signal control and processor and the recording unit for object-image distance related parameters output the electrical signal consistent with the signal receiving rule 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, the short-focus microlens array, the two-dimensional photosensitive film and the electrical signal control and processor and the recording unit for object-image distance related parameters are equivalent to the artificial retina.

[0022] The present invention also discloses a laser therapeutic apparatus formed on the basis of a three-dimensional optical processing machine, which adopts 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 combination, and uses an infrared light source that is partially transparent to human tissue to irradiate the area where the cancer tumor is located, so that the cancer tumor emits scattered light, and uses a large number of two-dimensional photosensitive units in the two-dimensional laser + photosensitive composite sheet to take pictures and record two angle coordinates of the two-dimensional real image of the cancer tumor, and 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 the two-dimensional real image of the cancer tumor is taken. While taking pictures and recording, a large number of laser units in the two-dimensional laser + photosensitive composite sheet send a two-dimensional laser with a projection image distance that is the same as the above object distance, with the edge shape of the cancer tumor tissue that needs to be removed, or with the shape of the blood vessels inside or outside the cancer tumor that need to be sintered and blocked, and the two-dimensional laser sent while taking pictures is focused to the object distance position of the edge of the cancer tumor tissue being photographed or the object distance position of the blood vessels inside or outside the cancer tumor. The two-dimensional laser sheet and the photosensitive sheet may be separate components, in which case a wavelength division multiplexer is used to separate the infrared light for photography that reaches the two-dimensional photosensitive sheet and the laser light for laser therapy that is emitted from the two-dimensional laser sheet.

[0023] The optical quasi-3D space converter of the present 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 converted fixed-position two-dimensional images are real images, and each two-dimensional real image has its specific object-image distance-related parameters related to the object distance of the three-dimensional object corresponding to the real image. Since the short-focus microlenses are an array structure arranged in parallel, the optical quasi-3D space converter of the present invention can provide a wide field of view, and the size of the image compressed or magnified by the quasi-3D space converter can be suitable for wide-field three-dimensional cameras, wide-field naked-eye observation three-dimensional real image projectors, or three-dimensional photoprocessing machines that synchronize three-dimensional photography with light processing, artificial eyes, etc. Since the quasi-3D space conversion obtains a two-dimensional real image, and the position of the image is fixed, it is technically easy to realize the above applications.

[0024] The optical quasi-3D space converter of the present invention can be applied to a 3D optical processing machine. The mobile positioning subsystem for 3D photographing of an object is the same as the mobile positioning subsystem for optical processing, so there is no error in the movement and alignment of the two systems, and high processing position accuracy can be achieved. The 3D optical processing machine can start the 2D light source of the optical processing subsystem while the 3D camera is moving and positioning to the position of the object to be processed, so as to achieve 3D optical processing (such as 3D cutting, welding, repairing, burning, etc.), and also improve the processing efficiency.

[0025] At the same time, the three-dimensional optical processing machine can be used for laser tumor removal. The tumor can be regarded as a group of point-like tumors (tumor points). When the photosensitive unit / image point is positioned to part or all of this group of tumor points, the laser unit adjacent to the photosensitive unit / image point that is three-dimensionally positioned to the tumor point, or the laser unit on the two-dimensional light-emitting sheet corresponding to the image point position, emits laser. The tumor point and the image point received by the photosensitive unit are very close to one-to-one correspondence. The laser emitted near an image point can be focused on the corresponding tumor point, thereby achieving the purpose of removing the tumor. This three-dimensional optical processing machine only needs to use a photographic positioning mobile platform, and does not require an additional laser irradiation to align the mobile platform. Because the photographic positioning mobile platform can have a microscopic magnification positioning function, its positioning accuracy can be very high. Therefore, the laser tumor removal position accuracy of this three-dimensional optical processing machine is also very high.

[0026] 3D optical processing machines can also be used in 3D laser welding technology. Laser welding is an 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 to facilitate the positioning of workpieces and the inspection of welding effects. First, the workpiece is positioned by a microscope, and then the laser welding head is moved to the positioning point for laser welding. Laser welding requires that the position of the laser beam on the workpiece cannot be significantly offset. If the laser beam is not aligned with the weld point, it is easy to cause welding defects. The 3D optical processing machine can emit a laser while the photosensitive unit is positioned at the position where the workpiece needs to be welded, so as to achieve the purpose of precise alignment welding. There is no need to move the laser processing subsystem after the positioning subsystem finds the position of the workpiece, which improves the welding accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Embodiment 1: The present invention discloses an optical quasi-three-dimensional space converter, which is suitable for converting a large three-dimensional space into a small quasi-three-dimensional space, such as Figure 1 As shown, specifically including:

[0054] As an objective lens, the zoom telephoto lens is used to receive light from the object side of a large three-dimensional space and form an intermediate real image;

[0055] As the short-focus micro-lens array of the eyepiece, each micro-lens in the short-focus micro-lens array converts the intermediate real image formed by the zoom telephoto lens into an intermediate virtual image according to the spatial angle range corresponding to each micro-lens;

[0056] The camera lens arranged on the short-focus micro-lens array side converts the intermediate virtual image into a fixed-position two-dimensional real image in a small quasi-three-dimensional space;

[0057] The object-image distance related parameter regulator is used to adjust the focal length of the zoom telephoto lens, short-focus micro-lens array, and camera lens, as well as the relative positions of the lenses, so that three-dimensional objects of different object distances are clearly imaged on a two-dimensional real image with a fixed image distance and a fixed position; and the conversion between a large three-dimensional space and a small quasi-three-dimensional space is completed. The object-image distance related parameters include the focal length of the zoom telephoto lens, short-focus micro-lens array, and camera lens, as well as the relative position data between them.

[0058] The focal length F0 of the zoom telephoto lens is greater than the focal length f of each micro-lens in the short-focus micro-lens array. iThe number of microlenses in the short-focus microlens array is ≥ 2, and the focal lengths of the microlenses in the short-focus microlens array may be the same or different. The focal lengths of the microlenses in the short-focus microlens array are f i Fixed focal length or variable focal length.

[0059] The zoom telephoto lens is a zoom telephoto lens or a zoom telephoto lens group formed by at least two lenses connected in series. The short-focus microlens array is a short-focus microlens array or a short-focus microlens group array. The short-focus microlens array is composed of at least two short-focus microlenses arranged in parallel. The short-focus microlens group array is composed of at least two short-focus microlens groups arranged in parallel. The short-focus microlens group is composed of at least two microlenses connected in series.

[0060] The object-image distance related parameter regulator can also convert the same three-dimensional object space twice or more by adjusting the relative positions of up and down, left and right, front and back, rotation, etc., to compensate for the deficiencies in the optical functions of the gap parts that do not participate in imaging in the short-focus micro-lens array and the edge parts of the micro-lenses with poor imaging quality.

[0061] The focal planes of the microlenses of the short-focus microlens array may all overlap with the focal plane of the zoom telephoto lens, or partially overlap and partially be on the left side of the focal plane of the zoom telephoto lens (crossing within the focal plane), or all be on the left side of the focal plane of the zoom telephoto lens (crossing within the focal plane).

[0062] The large three-dimensional object space within the object angle range Δα (Δα=α2-α1) from α1 to α2 is reduced to a three-dimensional virtual image space within the image angle range Δβ (Δβ=β2-β1) from β1 to β2 through the optical quasi-three-dimensional space converter. Δα and Δβ can be equal or unequal. The reduction ratio of the object to image size is related to the focal length ratio F0 / f i Related: F0 / f i The larger the object angle, the greater the reduction ratio. A large object angle range α can be divided into multiple small object angle ranges Δα i , each Δα i The three-dimensional space object in the short-focus micro lens is converted into a tiny image angle range Δβ by the quasi-three-dimensional space converter. i Three-dimensional virtual image within. Multiple tiny image angle ranges Δβ i The three-dimensional virtual image is merged into a three-dimensional virtual image with a large image angle range β as the second intermediate image.

[0063] Embodiment 2: The present invention discloses an optical quasi-three-dimensional space converter. The difference from Embodiment 1 is that this embodiment is applicable to the conversion between a small three-dimensional space and a large quasi-three-dimensional space, such as Figure 2As shown, the objective lens is a short-focus microlens array, and each microlens in the short-focus 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 forms an intermediate real image; the eyepiece is a zoom telephoto lens, which is used to convert the intermediate real image formed by the short-focus microlens array into an intermediate virtual image; the camera lens is arranged on the side of the zoom telephoto lens, and converts the intermediate virtual image into a two-dimensional real image with a fixed position in the large quasi-three-dimensional space.

[0064] Embodiment 3: The present invention discloses an optical quasi-three-dimensional real image space converter, which is different from Embodiment 1 in that: Figure 3 As shown, it also includes an intermediate image horizontal flipper, which is used to flip the intermediate real image formed by the zoom telephoto lens horizontally to the left and right to form a flipped intermediate real image; a short-focus microlens array as an eyepiece, each microlens in the short-focus 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; an object-image distance related parameter regulator, which is used to adjust the focal length of the zoom telephoto lens, the intermediate image horizontal flipper, the short-focus microlens array and the relative position between each lens.

[0065] Embodiment 4: The present invention discloses an optical quasi-three-dimensional space converter, which is different from Embodiment 2 in that: Figure 4 As shown, it also includes an intermediate image horizontal flipper, which is used to flip the intermediate real image formed by the short-focus microlens array horizontally to the left and right to form a flipped intermediate real image; a zoom telephoto lens as an eyepiece, which is 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 regulator, which is used to adjust the focal lengths of the zoom telephoto lens, the intermediate image horizontal flipper, the short-focus microlens array, and the relative positions of the various lenses.

[0066] Embodiment 5: Figure 5 As shown, based on Figure 1 The three-dimensional camera formed also includes a quasi-3D photoreceptor arranged on the side of the short-focus microlens array, which includes a fixed-position two-dimensional photosensitive film and an object-image distance related parameter recording unit. The two-dimensional photosensitive film records the two angular coordinates of the two-dimensional real image when taking pictures, and the object-image distance related parameter recording unit records a group of object-image distance related parameters corresponding to the object distance (third dimension) when taking this two-dimensional real image, so as to obtain the three-dimensional coordinates of the spatial object; the object-image distance related parameter regulator is also used to transmit the object-image distance related parameters to the object-image distance related parameter recording unit.

[0067] When implementing it, Fig.18As shown, a zoom telephoto convex lens (or a zoom telephoto convex lens group) is used as a zoom telephoto lens, a short-focus micro-convex lens array (or a short-focus micro-convex lens group array) is used as a short-focus micro-lens array, a convex lens (or a convex lens group) is used as a camera lens in a quasi-3D photoreceptor, and an arc-shaped two-dimensional photosensitive sheet composed of a large number of photosensitive units is used as a two-dimensional photosensitive sheet with a fixed position in the quasi-3D photoreceptor. The two-dimensional photosensitive sheet is used to take a photo to record two angular coordinates (two dimensions) of a 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) of the three-dimensional space object when shooting this two-dimensional real image, and obtains the three-dimensional coordinates of the three-dimensional space object. The azimuth of the two-dimensional image represents the azimuth of the position of the three-dimensional space object (or three-dimensional space image), and one azimuth has two angular coordinates. The object-image distance related parameters represent the object distance (or image distance) of the three-dimensional space object ((or three-dimensional space image), thereby realizing the conversion of three-dimensional coordinates to quasi-3D coordinates.

[0068] The projection azimuth and image distance of the two-dimensional light of each two-dimensional image source or two-dimensional light source correspond to a set of object-image distance related parameters; if this two-dimensional image source is obtained by using Figure 5 The projection image distance of each 2D image source can be obtained by shooting with a device. The corresponding set of object-image distance related parameters used in shooting can be used. If the set of object-image distance related parameters used in shooting is different from the object-image distance related parameters used in projection, they have a corresponding calculation relationship; if this 2D image source is generated by a computer, the projection image distance of each 2D image source corresponds to a set of object-image distance related parameters required for this 3D real image.

[0069] Example 6: Figure 6 As shown, based on Figure 1The three-dimensional real image projector formed also includes a quasi-three-dimensional projection image source generator including a fixed-position two-dimensional image source and an object-image distance related parameter providing unit arranged on the side of the short-focus microlens array. The quasi-three-dimensional projection image source generator quickly projects two-dimensional light of a fixed-position two-dimensional image source with different projection image distances provided by the object-image distance related parameter providing unit, and projects a three-dimensional real image in the air for naked eye viewing.
