TECHNICAL FIELD

[002] Aspects of this disclosure are generally related to three-dimensional imaging.

BACKGROUND

[003] Many people use smart phones.

SUMMARY

[004] All examples, aspects and features mentioned in this document can be combined in any technically possible way.

[005] This patent provides a novel stereoscopic imaging system. In the preferred embodiment, the improved stereoscopic imaging system would be incorporated onto a smart phone, which is called the stereoscopic smart phone (SSP). This is also referred to as a 3D smart phone. The SSP would work in conjunction with one or more stereoscopic head display units (SHDUs). Once this system is operational, it will allow significant improvements to video imagery. For example, the stereoscopic cameras on the SSP can move in position to alter stereo separation distance and change the convergence to optimally image a scene. These changes can occur in near real time, so as the scene changes, the cameras change accordingly. Consider the following situation with a roily polly bug. A SSP can be set up near the SSP and object tracking of the roily polly can occur. Each camera of the stereoscopic camera system on the SSP can track the roily polly and the stereo distance can change closer and farther away based on the distance of the roily polly. The roily polly can climb onto a rock and the convergence point of the stereo cameras moves upward and as it climbs downward into a hole, the convergence point of the stereo cameras moves downwards. While all of this is happening, the stereoscopic imagery can be passed via a wired or wireless connection to a stereoscopic head display unit (SHDU). A child in near real time can view the roily polly while wearing the SHDU. The digital images of the roily polly can be enlarged so the roily polly appears the size of a black lab puppy. A wide array of other objects and situations can also be imaged using this system, which overall enhance the viewing experience.

[0023] In some embodiments a very high-resolution camera pair(s) could be used in connection with the type pairs described above. In some embodiments, there could be a disparity between the camera resolution and that of the display system wherein the camera resolution was greater (i.e., provided ‘better resolution’) than that of the display system. These very high-resolution camera pair(s) could be used in connection with changes in camera field of view (FOV). In some embodiments, the field of view could change (e.g., decrease in size) with a corresponding change of image resolution (e g., increase in resolution). As an example, this embodiment could be used with a feedback mechanism wherein a user could, for example, start with a large FOV and then, thru an interactive cursor, indicate an area of interest and desired FOV. Then, the center point of the FOV would change to that point and the image area corresponding to that FOV and the resolution corresponding that FOV would create the image to be displayed.

[0024] The stereoscopic camera system has a variety of components, which include: aperture(s); lens(es); shutter(s); detector(s); mirror(s); and, display(s).

[0025] Aperture diameter would be consistent with the different lenses described below. Changeable or fixed type lenses or user selection of type lens chosen by the user. The current set of lenses within the smart devices is one option. Multi-shaped lenses (Note: this is analogous to reading glasses with variable portions of the lens based on look angle (e.g., top portion for looking straight forward and bottom portion for reading. This would be different to allow convergence (i.e., left lens and right lens in bottom portion would be canted differently.) Differing pointing angles can be based on the particular portion of the lens. Differing zoom can be based on the particular portion of the lens. Fisheye type lenses with high resolution. The idea is that different portions of the digital collection array would be associated with corresponding look angles through the fisheye lens The portion of the array which is used could be user specified. Alternatively, in some embodiments, automatic selection of the portion of the array selected could be based on input data from an inclinometer. Some embodiments comprise using a variable/ differing radius of curvature. Some embodiments comprise using a variable/ differing horizontal fields of view (FOV). Shutters timelines, etc. would be in accordance with the type technology chosen for the particular type detector array technology.

[0026] The standard types of detector arrays would be used for stereo camera pairs. Collection array could include for example, but not limited to: charge couple devices (CCD), complementary metal-oxide semiconductor (CMOS). For camera systems needing a nighttime capability of operation, options would include, but are not limited to: low light level TVs; infrared detector arrays such as (mercury cadmium telluride (MCT); Indium gallium arsenide (InGaAs); and quantum well infrared photodetector (QWIP).

[0027] Composite collection geometries of the collection array would be based on the desired viewing mode of the user. This would include, but would not be limited to: user selection of straight ahead for general viewing of the scene and specific objects at ranges greater that 20 - 30 feet where stereoscopic viewing becomes possible); variable convergence angles based upon the proximity of the object being viewed; to the left or to the right to provide a panoramic view (or, alternatively for scanning (e.g., left, to straight ahead, then to the right). Some embodiments comprise wherein a portion of the collection array would be facing straight ahead. Some embodiments comprise wherein a portion of the collection array would be constructed with different convergence angles. Some embodiments comprise wherein a portion of the collection array would be constructed with different look angles (left/ right; far left/ far right).

[0028] Left eye and right eye imagery could be merged and displayed on the smart device display. This composite image could then be viewed as by polarized glasses. Alternatively, the smart phone could be placed into a HDU with lenses to be converted into a virtual reality unit.

[0029] In some embodiments, the encasing framework of each of the lens could be rotated along 2 degrees of freedom (i.e., left/ right and up// down). Alternatively, the encasing framework of the detector array could be rotated along 2 degrees of freedom (i.e., left/ right and up// down). In some embodiments, a mirror(s) (or reflective surface) could be inserted to the stereo camera system. In a system configuration the user could rotate the mirror such that the desired viewing angles focused on the area/ objects selected by the user.

[0030] In some embodiments, mechanical turning of the collection arrays or lenses or the entire camera. This mechanical turning would correspond with the user’s desired viewing area (i.e., straight ahead or converged and some nearby location. This turning could be done electronically or by a physical mechanical linkage.

[0031] With respect to transmission, the first option would be for the person who collected the left and right eye data/ imagery to view the stereo imagery on his/ her head stereo display unit (HDU). This could be accomplished, for example, by a wire connection between the stereo phone and the stereo HDU. The user could also choose to send the stereo imagery to other persons. The transmission could be for single stereo pair(s) or streaming stereo video. The data transmitted could be interleafed (i.e., alternating between left eye data/ imagery and right eye data/ imagery). Alternatively, the data/ imagery could be transmitted via multi channel with separate channels for left and right eye data/ imagery. Alternatively, the left and right eye imagery frames could be merged for transmission. Using this technique, the HDU could use polarization or anaglyph techniques to ensure proper stereo display to the user. A further option would be store the left and right eye data/ imagery. This storage could be accomplished by, but not limited to the following: on the smart device; on a removable device such as a memory stick; or on a portion of the cloud set aside for the user’s storage, and at some later time download the stereo imagery to a device (e.g., computer) and subsequently displayed on a HDU.

[0032] There are a variety of modes of operations. Example modes of operation would include, but are not limited to the following: stereo snapshot; scanning; staring, tracking, and record then playback.

[0033] In some embodiments a very high-resolution camera pair(s) could be used in connection with the type pairs described above. In some embodiments, there could be a disparity between the camera resolution and that of the display system wherein the camera resolution was greater (i.e., provided ‘better resolution’) than that of the display system. These very high-resolution camera pair(s) could be used in connection with changes in camera field of view (FOV). In some embodiments, the field of view could change (e.g., decrease in size) with a corresponding change of image resolution (e.g., increase in resolution). As an example, this embodiment could be used with a feedback mechanism wherein a user could, for example, start with a large FOV and then, thru a interactive cursor, indicate an area of interest and desired FOV. Then, the center point of the FOV would change to that point and the image area corresponding to that FOV and the resolution corresponding that FOV would create the image to be displayed.

[0034] With respect to user interface, the type of control of the stereo camera pairs would be smart device dependent. For a smart phone device, for example, the principle screen could display a stereo camera icon.

[0035] Next, the Stereoscopic Head Display Unit (SHDU) will be discussed. Types of displays included both immersive (this could include, but would not be limited to: a very dark visor that can be brought down on the far side of the display to block viewing of the external scene; an electronic shutter external to the display and coincident with the HDU eyepieces could be of varying opacity )which could be initiated by the person wearing the head display unit; note that this ); or mixed reality with a relative intensity/ brightness of the intensity of the stereoscopic display relative to the external scene. A computer and memory would be integral to the HDU. A power supply would be integral to the HDU. The communications componentry would include, but is not limited to the following: communications port(s) (e.g., USB, HDMI, composite wire to connect to power source, smart device), antenna and receiver; associated circuitry. The audio componentry would include, but is not limited to: speakers, microphone, or both. A LRF is integral to ’smart device’ and used to determine range from the smart device to the location of the object selected by the user to calculate convergence angles for left and right viewing angles to provide proper stereoscopic images. In addition, a pseudo-GPS system can be integrated as described in US 10,973,485, which is incorporated by reference in its entirety.

[0036] In some embodiments, stereoscopic image processing will be performed on the images produced by the two stereoscopic cameras. One of the image processing techniques is image enhancement. These enhancement techniques include but are not limited to the following: noise reduction, deblurring, sharpening and softening the images, fdtering, etc. In an example of noise reduction, there would be two separate images each of which would undergo a separate noise reduction process. (Note that noise is random in nature and, therefore, a different set of random noise would occur in the left camera image from right camera. And, after the consequent reduction, a different set of pixels would remain in the two images.) Given these images were taken beyond the stereoscopic range, then the two images could be merged resulting a more comprehensive, noise free image. In some embodiments, stereoscopic image processing will include segmentation. These enhancement techniques include but are not limited to the following: edge detection methods; histogram-based methods, tree/graph-based methods; neural network based segmentation; thresholding; clustering methods; graph partitioning methods; watershed transformation; probabilistic; and Bayesian approaches. Given these images were taken beyond the stereoscopic range, a different technique for left and right images could be invoked. If the segmentation produced identical results, then there would be higher confidence in results. If the results were different, however, then a third segmentation method could be invoked, and an adjudication process resolve the segmentation.

[0037] In some embodiments of stereoscopic image processing, a set of left and right images would be produced over time. The user could identify an object(s) of interest which could be tracked over time. Stereoscopic image processing consisting of background suppression could be applied to both left and right images which could enhance stereoscopic viewing of the object(s) of interest. In some embodiments of stereoscopic image processing, false color could be added to the scene and/ or object(s) of interest within the scene. An example of stereoscopic image processing would be to use opposing anaglyph colors for left and right eye images. A further example would be to use color figures to provide augmented reality of stereoscopic images. [0038] In some embodiments of stereoscopic image processing, would be image compression for data storage and transmission. As an example, for compression as it applies to of stereoscopic image processing would be to: for portions of an image beyond stereoscopic ranges, apply stereoscopic image compression processing (to include but not limited to run-length encoding) to only that region to one of either left or right images, but not both. For that region that is within stereoscopic ranges, apply stereoscopic image compression processing to both the left and right images.

[0039] In some embodiments of stereoscopic image processing would include morphological processing which would include but not limited to: dilation, erosion, boundary extraction, region filling. An example for morphological processing as it applies to of stereoscopic image processing would be to perform erosion for the left image but not for the right. Left and right images could be alternated to permit the user to evaluate whether this type of processing was desirable.

[0040] In some embodiments of stereoscopic image processing, stereoscopic object recognition would be invoked. Techniques for stereoscopic object recognition include but are not limited to: cconvolutional neural networks (CNNs); and support vector machines (SVM). A number of support features include, but are not limited to: feature extraction; pattern recognition, edge detection; and corner detection. Examples of automated object recognition (AOR) processing as it applies to of stereoscopic image processing would be to: recognize brands of cars; recognize types of animals, optical character reading; optical character reading coupled with a translation dictionary. For example, CNN AOR could be performed on left camera imagery and SVM on right camera imagery. If both agree on the type object, that type object is presented to the user. However, if agreement is not reached by CNN and SVM, then a third type of recognition methodology such as feature recognition would be invoked.

[0041] In some embodiments of stereoscopic image processing would include image stabilization would be invoked. If a single stereoscopic image was desired by the user and if upon review of the image, the image was blurred dur to vibration or movement(s) of the stereoscopic cameras during the imaging interval then an option would be to decrease the shutter interval and repeat the stereoscopic image collection. If, however, a stereoscopic video collection was to be obtained by the user, then stereoscopic image processing would include, but not be limited to: selection of three or more reference points within the stereoscopic images (i.e., visible in both left and right images) and, from frame to sequential frame, adjust the sequential frame(s) to align the reference points; a border surrounding the displayed stereoscopic images could be invoked to reduce the overall area of the stereoscopic images.

The first camera 102 and the second camera 103 are separated by a stereoscopic distance. In the preferred embodiment, these would be maximally separated to enhance stereo separation to achieve stereoscopic vision at distances greater than a user could with his/her own stereoscopic distance. Some embodiments comprise placing mechanical extensions to further increase the stereo separation. In some embodiments, two phones would work in conjunction to further increase stereo distance. For example, a first smart phone could be placed in 10, 20 or 30 feet from a second smart phone. The video imagery could be synchronized and video imagery from a camera from the first phone and video imagery from a camera from the second phone can be used together to generate stereoscopic imagery. In some embodiments, these phones are to be manufactured with differing stereoscopic distances. In some embodiments, the stereoscopic distance can match that of a person. Some designs will therefore have a larger stereoscopic distance and other designs will have a smaller stereoscopic distance.

These components are the same for both cameras. First, there is the aperture which look outward through the two holes in the back of the phone and front of the phone as described in Figure 1. Next, there is a shutter with a variable speed. The is followed by a lens which will be described in some detail in subsequent figures. Depending on the detailed layout of the components, it is novel to insert a mirror to redirect the light which has passed through the lens to the sensor array which will be illustrated in subsequent figures. In some embodiments, the mirror is a deformable mirror. In some embodiments, the mirror is capable of working with adaptive optics. In some embodiments, the mirror is a curved mirror. In some embodiments, the mirror is a flat mirror. A processor and software support the operation of the camera system. For example, changing the camera viewing angle from looking straight forward to convergence mode where the left camera would look down and the right and the right camera would down and to the left. These viewing angles would intersect at a convergence point on the object of interest. These angles would be based on the proximity of the object of interest to the cameras. Depending on the design option selected there may be mechanical elements that interact with either components or the camera as a whole. There is the display which is part of the phone. Finally, there is communications link which transport data in for the mode of operation and data out to the display. Note that concepts taught in this patent are preferred to be placed in a smart phone; however, could be used in other smart devices.

In the preferred embodiment, this is performed using the same smart phone and the cameras alter the direction from which imagery is obtained. In the preferred embodiment, this is performed based on altering configuration of the componentry of the camera. In other embodiments, this is performed digitally, as is taught in US 17/225,610, AN IMPROVED IMMERSIVE VIEWING EXPERIENCE filed on 4/8/2021 and US Patent Application 17/237,152, AN IMPROVED IMMERSIVE VIEWING EXPERIENCE, filed on 4/22/2021, which are incorporated by reference in their entirety. 200 illustrates a smart phone. 20 IF illustrates the front face of a smart phone. 20 IB illustrates the back of the smart phone. 202 illustrates a first camera of a stereoscopic camera pair. 202B illustrates the center angle of the first camera 202, which is the direction to the center of the field of view of the first camera 202. 203 illustrates a second camera of a stereoscopic camera pair. 203B illustrates the center angle of the second camera 203, which is the direction to the center of the field of view of the second camera 203.

In the preferred embodiment, the convergence point is in the midline (along the plane orthogonal to the front of the smart phone 201 from a point halfway in between the first camera 202 and the second camera 203). In some embodiments, the convergence point can be: at the level of the first camera 202 and the second camera 203; above the level of the first camera 202 and the second camera 203; below the level of the first camera 202 and the second camera 203; or, off of midline. The convergence point can be any point in (x, y, z) space seen by the first camera 202 and second camera 203. In some embodiments, if the relative positions of two smart devices are known, a camera from the first smart device and a camera from the second smart device can also be used to yield stereoscopic imagery, as taught in this patent and in the patents incorporated by reference in their entirety.

Note that 312 is located towards the bottom and towards the first camera of a stereoscopic camera pair. Together, these provide a unique capability to the smart phone with stereoscopic cameras. A progressive lens has a corrective factor to provide looking straight forward and in a ‘progressive’ manner gradually increases magnification in a downward and inward direction through the progressive lens. Note that electronic correction can occur to account for refraction through the lens. In some embodiments, the amount of magnification can be increased in the medial or inferior-medial direction. This can be performed for eyeglasses, which is referred to as “convergence type progressive eyeglasses”.

[00159] Figure 5C illustrates a front view of a curved mirror concept for smart phone with stereoscopic camera capability. 503 illustrates a curved mirror encased by a frame 504.

[00160] Figure 5D illustrates a front view of a curved mirror concept for smart phone with stereoscopic camera capability. 503 illustrates the curved mirror encased by a frame 504. In the preferred embodiment, a spherical-type curvature is used. In some embodiments, a cylindrical- type curvature is used. In some embodiments, the curvature can include both spherical-type curvature and cylindrical-type curvatures. In some embodiments, multiple (at least two) different curved mirrors can be used. For example, if for a long range zooming, a first type of curved mirror can be utilized. If for medium range zooming, a second type of curved mirror can be utilized. These can be used one at a time, so the first type of curved mirror and second type of curved mirror can be swapped out depending on what object is being viewed.

[00161] Figure 5E illustrates a front view of a deformable mirror concept for smart phone with stereoscopic camera capability. 505 illustrates a deformable mirror encased by a frame 506. An inventive aspect of this patent is to use a deformable mirror in conjunction with a stereoscopic camera system. [00162] Figure 5F illustrates a top-down view of the deformable mirror concept for smart phone with stereoscopic camera capability at time equals 1. 505 illustrates a deformable mirror encased by a frame 506. Note the contour of the deformable mirror at this first time point.

[00163] Figure 5G illustrates a top-down view of the deformable mirror concept for smart phone with stereoscopic camera capability at time equals 2. 505 illustrates a deformable mirror encased by a frame 506. Note the contour of the deformable mirror at this second time point, which is different from the contour at the first time point. At a first time point, for the first camera the curvature of the first deformable mirror has a first focal point. At a second time point, for the first camera the curvature of the first deformable mirror has a second focal point, which is different from the first focal point. At a first time point, for the second camera the curvature of the second deformable mirror has a first focal point. At a second time point, for the second camera the curvature of the second deformable mirror has a second focal point, which is different from the first focal point. Thus, at the first time point the first deformable mirror and second deformable mirror would optimize imagery at a first location. This could be an object in the scene or a point in space. This could be a first convergence point. Thus, at the second time point the first deformable mirror and second deformable mirror would optimize imagery at a second location. This could be an object in the scene or a second location. This could be a second convergence point. The second convergence point would be different from the first convergence point. The deformable system is inventive because it maintains high light collection and can rapidly alter the projection of this light from the scene onto the detector. In some embodiments, eye tracking of a user is performed. Based on eye tracking metrics of a user, the deformable mirrors deform to optimize image acquisition from those areas. This includes a location where a user is looking. Thus, imagery collected can be optimized based on where a user is looking. Thus, as the user looks a new objects via saccades movements of his/her eyes, the stereoscopic deformable mirror system can deform to adapt to new areas where the user is looking. Similarly, as the user tracks objects as it moves with smooth tracking movements of his/her eyes, user is looking. Thus, imagery collected can be optimized based on where a user is looking. Thus, as the user looks a new objects via saccades movements of his/her eyes, the stereoscopic deformable mirror system can deform to adapt to new areas where the user is looking.

[00164] Figure 6A illustrates a movable lens for smart phone with stereoscopic camera capability. This figure is the first of three different potential of the smart phone with stereoscopic cameras capability. Figure 6A depicts a movable lens which could be used to change the look angle. Light 601 is shown as a series of parallel wavy lines entering the lens 602. In this case, the lens is the progressive type lens described in Figure 3C. The position of the lens at Time 1 is such that the light enters the top portion of the lens which imagery looking straight forward and no convergence point for the left and right viewing angles is used. At Time 2, the position of the lens has shifted upward and the light 601 now enters the bottom portion of the lens 604. The bottom right portion of the left lens causes the look angle to shift down and to the right. The bottom left portion of the right lens causes the look angle to shift down and to the left. Under this configuration, the viewing angles of the left and right lenses intersect (i.e., converge) and, collectively, provide a stereoscopic view.

[00165] Figure 6B illustrates the composite sensor array concept. The light has already passed through the lens and is converging on one of the sensor arrays of the composite sensor arrays described for Figure 4. At Time 1. the light enters the center array 608 and provides looking straight ahead imagery. At Time 2, the array has rotated, and the light impinges, in this case, on sensor array 609. Thus, the viewing angles from the left and right cameras intersect and provide stereoscopic imagery.

[00166] Figure 6C illustrates a switching out of cameras from Day 1 to Day 2. Note this could be analogous switching lenses on today’s digital cameras. On Day 1, 611 shows the camera box; 612 the aperture, 613 the shutter; 614 the lens; 615 the sensor array and 616 the communications port. On day 2, the user selects a different; takes out the camera used on day 1 and inserts a totally different camera 617 of the same size and shape as the camera uses on Day 1. On Day 2, the aperture 618 is larger and the lens 621 has a curvature. 620 illustrates the shutter. 622 the sensor array and 623 the communications port. In some embodiments, the cameras can be stored on the smart phone and swapped out through mechanical processes on the smart phone. In other embodiments, swapping out can be through manual processes, as is done with today’s SLR cameras. Collectively, Figure 6A, Figure 6B and Figure 6C demonstrate the flexibility of the smart phone with stereoscopic cameras.

[00167] Figure 7A illustrates the Stereoscopic Head Display Unit (SHDU). This figure illustrates key aspects of the Stereoscopic Head Display Unit. Figure 7A shows example placements of key components of the SHDU. 701 illustrates the overall headset. 702 illustrates the left eye display. 702A illustrates the left eye tracking device. 703 illustrates the right eye display. 703A illustrates the right eye tracking device. 704 illustrates the processor. 705 illustrates the left ear speaker. 706 illustrates the power supply. 707 illustrates the antenna. 708 illustrates the right ear speaker. 709 illustrates the inclinometer (or inertial measurement unit). 710 illustrates the microphone. 711 illustrates the communications port. 712 illustrates a scene sensing device.

[00168] Figure 7B shows a side view of a transformable SHDU display unit with an eyepiece cover with augmented reality mode and virtual reality mode. 713A illustrates the side of the frame of the SHDU 701 at Time Point #1. 714A illustrates an eye piece cover. In the preferred embodiment, the eyepiece cover is connected to the SHDU 701 via a hinge. This is called a transformable SHDU because it can transform from a virtual reality type display (where the real world is blocked out) to an augmented reality type display (where the user can see both the virtual world and the real world). Thus, at Time Point #1, the transformable SHDU is in augmented reality mode. The eye piece cover is in the elevated position and does not block the wearer of the SHDU from seeing the external area around him/ her. If the wearer is concurrently viewing virtual imagery (e.g., stereoscopic imagery from smart phone with stereoscopic cameras), this would constitute augmented mixed reality. 713B illustrates the side of the frame of the SHDU 701 at Time Point #2. 714B illustrates an eye piece cover, which is now in position over the front of the SHDU, so it is in virtual reality mode at Time Point #2. At Time Point #2, the eye piece cover has rotated down and now covers the eye piece. The wearer of the SHDU would be blocked from seeing the external area around him/ her. If the wearer is concurrently viewing stereoscopic imagery from smart phone with stereoscopic cameras, this would constitute virtual reality.

[00169] Figure 7C shows a side view of a transformable SHDU display unit with an electronic eye piece with augmented reality mode and virtual reality mode. 713C illustrates the side of the frame of the SHDU 701 at Time Point #1. 714C illustrates an electronic eye piece affixed the SHDU 701 at Time Point #1. At Time Point #1, the setting for the electronic eye piece is transparent and light 715C is able to pass through unfiltered on the SHDU display units. Thus, this is augmented reality mode because the user can see both the real world and the virtual world. 713D illustrates the side of the frame of the SHDU 701 at Time Point #2. 714D illustrates an electronic eye piece affixed the SHDU 701 at Time Point #2. At Time Point #2, the setting for the electronic eye piece is opaque and light 715D is not able to pass through unfiltered on the SHDU display units. Thus, this is virtual reality mode because the user can only see the virtual world. In some embodiments, the opacity ranges in varying degrees of opacity. Thus, the electronic eye piece can a range of realities - mixed reality to virtual reality.

[00170] Figure 8A illustrates wired connectivity means between smart phone with stereoscopic camera capability and stereoscopic head display unit. Figure 8A is the first of three principle connectivity means between the stereoscopic smart phone (SSP) and stereoscopic head display unit (SHDU). Figure 8A shows the front side of the SSP 800A connected to the SHDU 801A via a wire 802. The stereoscopic imagery would be available on both the smart phone display 800A and the SHDU 801A. There are multiple options of what to display on the smart phone display: single left eye image or right eye image filling the entire display; both left eye image and right eye image on a split screen display; a merged left and right eye image to be viewed by a user wearing polarized or anaglyph glasses. In some embodiments, the SSP could be worn on a first user’s head and imagery obtained from the stereoscopic cameras on the back of the SSP as in Figure 1A. In addition, the imagery obtained from the back stereoscopic cameras on the back of the SSP could be displayed on the SHDU worn by a second user. This would allow the second user to view the same imagery as the first user, which can be displayed in near real time. In some embodiments, stereoscopic imagery obtained from the SHDU could be sent to the SSP.

[00171] Figure 8B illustrates wireless connectivity via BlueTooth means between smart phone with stereoscopic camera capability and stereoscopic head display unit. In this embodiment, the stereoscopic imagery would be transmitted from the SSP 800B via a BlueTooth connection 803 to the SHDU 80 IB which would be received through the SHDU’s antenna and subsequently routed to the processor and thence to the SHDU’s left and right displays. In addition, the imagery obtained from the back stereoscopic cameras on the back of the SSP could be displayed on the SHDU 80 IB worn by a second user. This would allow the second user to view the same imagery as the first user, which can be displayed in near real time. In some embodiments, stereoscopic imagery obtained from the SHDU could be sent to the SSP for display, as discussed in Figure 8A.

[00172] Figure 8C illustrates wireless connectivity via the Internet means between smart phone with stereoscopic camera capability and stereoscopic head display unit. In this embodiment, the stereoscopic imagery would be transmitted from the SSP 800C via an Internet connection 804 to the SHDU 801C which would received through the SHDU antenna and subsequently routed to the processor and thence to the SHDU left and right displays. In addition, the imagery obtained from the back stereoscopic cameras on the back of the SSP could be displayed on the SHDU 801C worn by a second user. This would allow the second user to view the same imagery as the first user, which can be displayed in near real time. In some embodiments, stereoscopic imagery obtained from the SHDU could be sent to the SSP for display, as discussed in Figure 8A.

[00173] Figure 9A illustrates system operation using the stereoscopic smart phone (SSP). 901 illustrates the SSP. 902A illustrates a digital icon symbolizing an app, which would be installed and appear on the general display containing multiple apps 903 (including settings, clock, messages). The user could touch his/ her finger 904A to the icon which would enable the SSP to receive commands for setting for the mode of operation of the stereoscopic cameras. These commands could be issued through but limited to: default settings; voice commands by the user into the smart phone via a microphone; antenna 905; via wire 906 into the data port 907; electronic message from the SHDU received at the smart phone. Note that a pull-down menu could appear on the smart phone display once the starting process has been initiated or by pull down menu on the SHDU.

[00174] Figure 9B illustrates near real-time stereo mode at time N. At Time N, the user is enjoying a day at the beach and the stereoscopic cameras are pointed straight ahead at a small ship passing by. The smart phone display shows a split screen of left viewing perspective imagery 908 taken by the left camera and right viewing perspective imagery 909 taken by the right camera.

[00175] Figure 9C illustrates system operation using the stereoscopic smart phone (SSP) with convergence mode. 901 illustrates the SSP. 902B illustrates a digital icon symbolizing the convergence option, which would be installed within the app. The user could touch his/ her finger 904B to the convergence icon. The cameras will adjust according to the convergence point.

[00176] The user touches the display and the current mode of operation of the stereoscopic cameras is indicated by an icon 902B. A command “Converge Near” is issued and the mode of operation changes to convergence at short range The user can the read his/ her book and see it in stereo on the SHDU. In some embodiments, eye tracking can be used to determine a location where in the user’s environment a user is looking. Then, the stereoscopic cameras will adjust the convergence and zoom settings in order to optimize viewing of the location where the user is looking.

[00177] Figure 9D illustrates convergence mode at time N+l. At a later time, Time N+l, the user wearing the SHDU decides to read a book using the SSP under convergence mode. The book is also shown on the smart phone display. Split screen is illustrated 908B and 909B for left and right eyes respectively. Note that in some embodiments, the stereo distance is adjusted so that it is different in Figure 9D as compared to Figure 9B. This could be done by using either the stereoscopic cameras on the front of the SSP or the stereoscopic cameras on the back of the SSP. In some embodiments, a novel stereoscopic camera setup with adjustable stereo distances is disclosed.

[00178] Figure 10A illustrates of before application of automatic object recognition as displayed on the stereoscopic head display unit.

[00179] The purpose of these Figures is to illustrate of before and after application of automatic object recognition (AOR) as displayed on the SHDU. The context for this figure is that the wearer is taking a hike in the forest. The smart phone with stereoscopic cameras could be worn as a body camera, running continuously. The body camera is operating in a look forward mode scanning back and forth covering a hemispherical or near hemispherical field of regard. The SHDU could be operating in the mixed reality mode. Figure 10A depicts the cluttered forest scene with trees, bush and grass and, some objects of possible interest which are difficult to distinguish among all the forest vegetation. The scene as it appears at Time 1 is shown on the SHDU 1001 using a left eye display 1002 and right eye display 1003. The user issues the command “Run AOR” and, in a very short time interval, Figure 10B appears on the SHDU displays.

[00180] Figure 10B illustrates after application of automatic object recognition as displayed on the stereoscopic head display unit. Again, the user in the forest enjoying the daytime hike. The smart phone is worn like a body camera and in the scanning mode (at least a 60 degree arc covering the path and 30 degrees to either side) alternating between looking straight ahead and looking down at close range. The SHDU is in the mixed reality mode an the AOR and Al are operating together. As circumstances would happen, there was a item of interest (e.g., snake which is dangerous) near the path. The AOR would detect and classify the snake and rapidly pass the information to the Al. The Al would assess the situation as ‘danger close’ and immediately provide feedback to the user (e.g., flash ‘STOP, STOP, STOP’ in big red letters on the SHDU displays). The SHDU speakers would sound the alarm and repeat STOP. There are literally numerous situations wherein the combination of AOR and Al would be beneficial to the user. Figure 10B thus illustrates wherein the AOR has correctly classified the man and the deer in the scene. 1004A illustrates a man visible through the left see-through portion of the SHDU. Note that in some embodiments, an image from a left stereoscopic camera of a man can be displayed on the left eye display of the SHDU 1004B illustrates a man visible through the right see-through portion of the SHDU Note that in some embodiments, an image from a right stereoscopic camera of a man can be displayed on the right eye display of the SHDU. 1005 A illustrates a deer visible through the see-through portion of the SHDU. Note that in some embodiments, an image from a left stereoscopic camera of a deer can be displayed on the left eye display of the SHDU. 1005B illustrates a deer visible through the see-through portion of the SHDU. Note that in some embodiments, an image from a right stereoscopic camera of a deer displayed on the right eye display of the SHDU. Note that in some embodiments, some items within the scene have been filtered (subtracted from the scene). This improves understanding of the items of interest. Note that in some embodiments, a novel augmented reality feature is to label an item within the field of view, such as the men and deer are labeled for easy user recognition.

[00181] Figure 10C invokes another stereo camera unique technology. Specifically, since the cameras are of higher resolution than the SHDU displays, the pixels on the display are down sampled in order to get the full scene in the field of view (FOV) onto the SHDU displays. At the user command “Focus deer”, the stereoscopic cameras change the FOV to the narrow field of view (NFOV). For the NFOV, the down sampling is discontinued and, in a very short time interval, the left image 1006A of the deer from the left stereoscopic camera is displayed in full resolution on left eye display and the right image 1006B of the deer from the right stereoscopic camera deer is displayed in full resolution on right eye display. These images are displayed at Time 1++.

[00182] At each of pre-planned FOVs the AOR is run, and objects of potential interest are identified and displayed in the SHDU displays.

[00183] For example, consider this scenario as the walk progresses, it becomes necessary for the user to cross a road. A very quiet electric vehicle (EV) is approaching. The AOR recognizes the vehicle and passes it to the Al. Al self tasks the question ‘is it safe for the user to cross the road’. The SHDU is equipped with a laser range fonder (LRF) which is used to determine range from the user to the EV and range rate of change of the of the EV (i.e., the Al problem is “how fast is the EV going?” and “when will the vehicle get to the user location?”). If the expected arrival time of the EV is such that the EV might intersect with the user, then the SHDUs would flash in large letters ‘DANGER, DANGER, DANGER’. The speakers in the SHDU would sound a warning siren. This could be performed in a variety of scenarios. [00184] Figure 11 A illustrates integration of image stabilization for a user in a scene where there is vibration.

[00185] The scene depicted in Figure 11A is that of a user 1101 riding in a subway along with other passengers labeled 1104. The user 1101 is wearing a SHDU 1102 and holding a stereoscopic camera wherein the phone is linked into the internet. The user spots an article of interest and downloads the article. The subway environment is such that there is considerable vibration thereby, making reading difficult. The user decides to invoke stereoscopic image stabilization. Note that the user, in this case, could invoke either SHDU setting for either mixed reality (MR) wherein the user could read the article and simultaneously watch the ongoing activities in the subway car. Alternatively, the user could invoke the option on the SHDU for virtual reality (VR) and obscure to external scene and focus solely on the article of interest. Note that the user could easily change form the VR mode to the MR mode if there were announcements in the subway communication system.

[00186] Figure 11B shows selection of points within the image to use for image stabilization. The SHDU 1105 displays wherein, for the stereoscopic image stabilization for left eye display has selected three words (1106, 1107 and 1108) within the displayed image (text in this example) as reference points to adjust left eye image frame display to sequential next left eye image frame display. Similarly, 109, 1110, and 1111 are reference points for the right eye display and are used to adjust right eye image frame display to sequential next right eye image frame display. This adjustment process from frame to frame would continue until the user proceeded to other parts of the article at which time the stereoscopic image stabilization process would select new reference points.

[00187] Figure 11C illustrates selection of points within the scene to use for image stabilization. A user 1112 on a walk thru an area of interest which, in this case is an urban area. The user, 1112, is wearing a SHDU 1113 and has a smart stereoscopic camera 1114 in a body wear position to operate in the continuous mode operation of streaming stereoscopic imagery from the stereoscopic cameras. Within the area within which the user is walking there are structures including a first building 1115, a second building 1116 and a fountain 1117, each of which has distinctive features which could be used as reference points for stereoscopic image stabilization. Note that the user may choose to use the microphone on the SHDU to record observations during the walk thru the area of interest. [00188] Figure 11D illustrates stereoscopic image stabilization on the SHDU. Figure 11D shows the SHDU 1118 wherein, for the stereoscopic image stabilization for left eye display has selected three key points within the area (1119, 1120 and 1121) as reference points to adjust left eye image frame display to sequential next left eye image frame display. Similarly, 1122, 1123, and 1124 are reference points for the right eye display and are used to adjust right eye image frame display to sequential next right eye image frame display. This adjustment process from frame to frame would continue until the user proceeded to other parts of the article at which time the stereoscopic image stabilization process would select new reference points. In some embodiments, for the left image displayed in the SHDU 1118, a first set of points is used for image stabilization and for the right image displayed in the SHDU 1118, the same first set of points is used for image stabilization. In other embodiments, for the left image displayed in the SHDU 1118, a first set of points is used for image stabilization and for the right image displayed in the SHDU, a second set of points is used for image stabilization wherein the first set of points are different from the second set of points.

[00189] FIG. 12A illustrates determining a stabilization point and field of view (FOV) for the left eye imagery and right eye imagery. Left eye imagery and right eye imagery at time = N and time = N + 1 are shown. 1200 illustrates a point in the left eye imagery, which is used for image stabilization at time = N. 1200A illustrates the field of view (FOV) from the left eye imagery. 1200B illustrates a portion of the field of view (FOV) from the left eye imagery, which is the portion to be displayed to a user. Note that 1200B is a subset of 1200A, which is determined based on point 1200. In the preferred embodiment, 1200A is based on using the point 1200 as the center of 1200A. 1201 illustrates a point in the right eye imagery, which is used for image stabilization at time = N. 1201A illustrates the field of view (FOV) from the left eye imagery. 1201B illustrates a portion of the field of view (FOV) from the left eye imagery, which is the portion to be displayed to a user. Note that 1201B is a subset of 1201A, which is determined based on point 1201. In the preferred embodiment, 1201 A is based on using the point 1201 as the center of 1201A. 1202 illustrates the point in the left eye imagery, which is used for image stabilization at time = N + 1. 1202A illustrates the field of view (FOV) from the left eye imagery. 1202B illustrates a portion of the field of view (FOV) from the left eye imagery, which is the portion to be displayed to a user. Note that 1202B is a subset of 1202A, which is determined based on point 1202. In the preferred embodiment, 1202A is based on using the point 1202 as the center of 1202A. 1203 illustrates the point in the right eye imagery, which is used for image stabilization at time = N + 1. 1203 A illustrates the field of view (FOV) from the left eye imagery. 1203B illustrates a portion of the field of view (FOV) from the left eye imagery, which is the portion to be displayed to a user. Note that 1203B is a subset of 1203A, which is determined based on point 1203. In the preferred embodiment, 1203 A is based on using the point 1203 as the center of 1203A. In some embodiments, a characteristic feature which can be easily distinguished in the image is used as a stabilizing point for both the left eye imagery and the right eye imagery. In some embodiments, the stabilizing point for the left eye imagery is different from the stabilizing point for the right eye imagery. In some embodiments, image stabilization is used for close range imagery, but not for longer range imagery. In some embodiments, a delay of less than 5 seconds is performed.

[00190] Figure 12B illustrates displaying stabilized stereoscopic imagery on a SHDU. 1204 illustrates the stereoscopic head display unit (SHDU). The top image illustrates what is displayed in a SHDU at time = N + delay, which includes the portion of the field of view (FOV) from the left eye imagery 1200B for the left eye display and the portion of the field of view (FOV) from the right eye imagery 1201B for the right eye display. The bottom image illustrates what is displayed in a SHDU at time = N + delay, which includes the portion of the field of view (FOV) from the left eye imagery 1202B for the left eye display and the portion of the field of view (FOV) from the right eye imagery 1203B for the right eye display.

[00191] Figure 13A illustrates the SSP with its stereoscopic cameras in a first position, which is wide. 1300A illustrates the SSP in a first configuration at time = N. 1301A illustrates a first camera of the SSP’s stereoscopic camera system, which is located at a first position on the SSP. 1302A illustrates a second camera of the SSP’s stereoscopic camera system, which is located at a second position on the SSP. Note that the first camera 1301A is separated from the second camera 1302A by a first stereo distance.

[00192] Figure 13B illustrates the SSP with its stereoscopic cameras in a second position, which is wide. 13006 illustrates the SSP in a second configuration at time = N + 1. Note that the second configuration is different from the first configuration. 1301B illustrates the first camera of the SSP’s stereoscopic camera system, which is located at a third position on the SSP. 1302B illustrates the second camera of the SSP’s stereoscopic camera system, which is located at a fourth position on the SSP. Note that the first camera 1301B is now separated from the second camera 1302B by a second stereo distance, which is different from the first stereo distance. Note that in this example, the second stereo distance is smaller than the first stereo distance.

[00193] Figure 13C illustrates the SSP with its stereoscopic cameras in a third position, which is also narrow, but shifted in position as compared to Figure 12B. 1300C illustrates the SSP in a third configuration at time = N + 2. Note that the third configuration is different from the first configuration and also different from the second configuration. 1301C illustrates the first camera of the SSP’s stereoscopic camera system, which is located at a fifth position on the SSP. 1302C illustrates the second camera of the SSP’s stereoscopic camera system, which is located at a sixth position on the SSP. Note that the first camera 1301B is separated from the second camera 1302B by the second stereo distance, but the position of the cameras is shifted. This novel design improves tracking of small objects that move, such as a roily polly. In this example, the cameras are shown to move along a line. This is called a camera bar design. In some embodiments, the cameras could move up, down, forward, back, left or right. In some embodiments, the cameras’ orientations can also be adjusted in roll, pitch and yaw. In some embodiments, the movements of the cameras can be coordinated with convergence as shown in Figure 2C. Thus, a novel aspect of this system is that the SSP’s stereoscopic cameras can be reconfigured into different positions and orientations on the SSP. This reconfigurable design would allow depth at various distances and could achieve depth at ranges of < 2 inches satisfactory. In some embodiments, a first set of lenses for the stereoscopic camera system could be used for a first stereo distance and a second set of lenses for the stereoscopic camera system could be used for a second stereo distance wherein the first set of lenses are nearer focus lenses than the second set of lenses and the first stereo distance is smaller than the second stereo distance.

[00194] Figure 14 illustrates optimizing stereoscopic imaging. 1400 illustrates determining an object of interest. The preferred embodiment is to use automatic object recognition (AOR). Some embodiments comprise using eye tracking, as taught in US Patent Application 16/997,830, ADVANCED HEAD DISPLAY UNIT FOR FIRE FIGHTERS, filed on 8/19/2020. Some embodiments comprise wherein a user selects an object of interest via a graphical user interface or voice commands. 1401 illustrates determining the distance and angle from the stereoscopic cameras to the object of interest. The preferred embodiment is to use a laser range finder, as taught by US Patent 11,006,100, SMART GLASSES SYSTEM. Other distance measurement technologies are also possible. In some embodiments, the colors and brightness of the images are also determined. 1402 illustrates reconfiguring stereoscopic cameras based on the distance from the stereoscopic camera wherein reconfiguring the stereoscopic cameras comprises adjusting: changing the stereo separation of the left stereoscopic camera from the right stereoscopic camera; moving the left stereoscopic camera and the right stereoscopic camera; changing the convergence of the left stereoscopic camera and the right stereoscopic camera; changing the zoom setting of the left stereoscopic camera and the right stereoscopic camera; and, changing the ISO setting of the left stereoscopic camera and the right stereoscopic camera. Other adjustments include: adjusting the shutter speed; adjusting the focal length; adjusting the field of view; adjusting the detector position / orientation; adjusting the camera position / orientation; adjust the convergence angle; and adjusting a deformable mirror. In some embodiments, these adjustments are also based on the colors and brightness of the images. In some embodiments, a table for optimized stereoscopic camera settings is generated based on distance. This table can be referenced as a look up table.
