TECHNICAL FIELD
[0001] The present application belongs to the field of optical three-dimensional imaging, and particularly relates to an optical quasi-three-dimensional real image space converter and applications such as three-dimensional photographing, three-dimensional projection and three-dimensional optical processing based on the optical quasi-three-dimensional real image space converter. BACKGROUND
[0002] The commonly used cameras can only record the two-dimensional world without the third dimension distance or depth information, and some auxiliary technologies such as ultrasonic ranging, laser radar ranging, infrared ranging, monocular structured light ranging and binocular ranging are needed to obtain the distance or depth information; 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 the 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 angles of view 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] At present, the Chinese patent application with the publication number CN119902383A discloses an optical quasi-three-dimensional real image space converter, but it needs an intermediate image horizontal flipper to flip the intermediate image. However, the manufacturing process of the intermediate image flip lens involves the precise arrangement of the microlens array and the precise control of the refractive index distribution of the micro convex lens surface or the micro self-focusing lens, and thus has high manufacturing cost.

The two-dimensional images with fixed positions obtained by conversion are real images, and each two-dimensional real image has a specific object-image distance related parameter corresponding to the object distance of the three-dimensional object. Since the short-focus micro-lens is arranged in an array structure, the optical quasi-three-dimensional real image space converter can provide a wide field of view, and the size of the image obtained by compression or magnification can be applied to a wide-field three-dimensional camera, a wide-field three-dimensional real image projector for naked eye observation, a three-dimensional photo and optical processing synchronous three-dimensional optical processing machine, an artificial eye, etc. Since the quasi-three-dimensional real image space conversion is a two-dimensional real image, and the position of the image is fixed, the above applications are easy to realize in technology.

Through the verification of the inventor: in a short distance, it can be used to detect the object distance more accurately and at a lower cost, and is suitable for application in a short distance; the detection accuracy of the object distance in a long distance is low, and is not suitable for long distance use.
[0016] The optical quasi-three-dimensional real image space converter can be applied to a three-dimensional optical processing machine, and the moving positioning subsystem for three-dimensional photographing and the moving positioning subsystem for optical processing are the same, so there is no error in the movement alignment of the two systems, and high processing position accuracy can be achieved. The three-dimensional optical processing machine can start the two-dimensional light source of the optical processing subsystem while the three-dimensional camera is moving and positioning to the position of the object to be processed, to realize three-dimensional optical processing (such as three-dimensional cutting, welding, repair, burning, etc.), and also improve the processing efficiency.
[0017] Meanwhile, the three-dimensional light processing machine can be applied to laser tumor resection. The tumor can be regarded as a group of point-like tumor objects (tumor points). When the photosensitive unit / pixel is positioned to part or all of the group of tumor points, the laser unit adjacent to the photosensitive unit / pixel positioned to the tumor points, or the laser unit on the two-dimensional light-emitting sheet corresponding to the pixel position, emits laser. The tumor points are very close to one-to-one correspondence with the pixels received by the photosensitive unit. The laser emitted near a pixel can be focused on the corresponding tumor point, thereby achieving the purpose of resecting the tumor. The three-dimensional light processing machine only needs to use the photographic positioning moving platform, and does not need an additional laser irradiation alignment moving platform. Because the photographic positioning moving platform can have a microscopic magnification positioning function, the positioning accuracy can be very high. Thus, the laser tumor resection position accuracy of the three-dimensional light processing machine is also very high.
[0018] The three-dimensional light processing machine can also be used in three-dimensional laser welding technology. Laser welding is a high-efficiency welding method using a high-energy-density laser beam as a heat source. The laser welding machine is configured with a microscope and a CCD display subsystem, facilitating positioning of the workpiece and inspection of the welding effect. The workpiece is first positioned by the 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 have obvious deviation. If the laser beam is not aligned with the welding point, welding defects are easily caused. The three-dimensional light processing machine can emit laser while the photosensitive unit is positioned to the position of the workpiece to be welded, thereby achieving the purpose of accurate alignment welding. The laser processing subsystem does not need to be moved after the positioning subsystem finds the position of the workpiece, thereby improving the welding accuracy. BRIEF DESCRIPTION OF DRAWINGS

The large number of two-dimensional photosensitive units in the two-dimensional laser + photosensitive combination sheet are used to photograph 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 and provided by the unit recording the corresponding object distance (third dimension) when the two-dimensional real image of this cancerous tumor is photographed. At the same time as the photographing and recording, the large number of laser units in the two-dimensional laser + photosensitive combination 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 to be sintered and blocked. Simultaneously with the imaging process, a two-dimensional laser is focused onto the edge of the cancerous tumor tissue or the location of blood vessels within (or outside) the tumor. The laser intensity density at the focused location is significantly higher than at other locations. When the laser intensity density at the focused location reaches the threshold required for laser processing of the cancerous tumor, laser processing can be completed. By repeatedly sending two-dimensional lasers at different distances corresponding to the edge of the cancerous tumor tissue or blood vessels within (or outside) the tumor, achieving the laser intensity density threshold for processing, laser treatment can be performed on cancerous tumors at various depths or on tumors with blocked blood vessels within (or outside) the tumor.
[0043] Example 11: As Figure 14 As shown, it is based on Figure 8 The three-dimensional optical processing machine shown is another specific embodiment of a laser therapy device for cancer tumors (by cutting the edge tissue of the tumor or blocking blood vessels inside (or outside) the tumor).
[0044] The difference between Embodiment 10 and Embodiment 9 is that Embodiment 10 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.
[0045] In specific use, the present application can use laser or non-laser, can use various wavelengths of light, such as visible light, infrared light, ultraviolet light, X-ray, and even electromagnetic waves (also a kind of light). Moreover, the light can be the light emitted by the object itself (such as the infrared light, fluorescence, etc. of the object itself), or the reflected light, scattered light, or transmitted light from the object when the light is used to irradiate the object. For example, when using the three-dimensional camera of one of the applications of the present application, when using the three primary colors of light visible to our human eyes, the color stereo photograph of the object can be taken; when using infrared light, the stereo photograph of the infrared light from the object can be taken; when using ultraviolet light, the stereo photograph of the ultraviolet light from the object can be taken; when using X-ray, the stereo photograph of the X-ray from the object can be taken (especially when using X-ray, which can be used to take the three-dimensional structure of the human body); when using electromagnetic waves, the stereo photograph of the electromagnetic waves from the space object can be taken.
