It will be appreciated by those skilled in the art that in other embodiments, a continuous "surface light source" may be emitted by other techniques, such as time of flight ("TOF") techniques, and the distance between the light source (e.g., laser, LED, etc.) and the object may be rapidly calculated by recording the time that the reflected light reaches the receiver, thereby obtaining two-dimensional or three-dimensional information such as 3D images and contours of the target object.
In an embodiment of the present invention, the display unit 103 may be a light projection device. The light projection device may project visible and/or invisible light. The light projection device may be a visible light projection device, such as a galvanometer, pico projector, configured to project visible light on a target object of interest to the user. For example, when a low-vision user goes out outdoors, if the user goes up and down stairs, the portable visual assistance device 100 of the present invention can be used, the light emitted by the image capturing unit 102 forms the contour of the stairs on the multi-level stairs and is displayed on the stairs in an overlapping manner, so that the low-vision user can accurately see the width and height of the stairs, and accidents caused by unclear stair step boundaries are avoided.
Of course, the light projection device may also be an invisible light projection device configured to project invisible light (e.g., infrared light not visible to the human eye, etc.) onto a target object of interest to the user. The user can see the visual auxiliary additional information superimposed on the stairs or other target objects clearly through a special device such as a mobile phone or a camera of AR glasses or the like.
In an embodiment of the invention, the display unit 103 may be an electronic display screen, such as AR augmented reality type of glasses for aiding vision that incorporate optical and electrical hardware and software, designed to capture images of a user's surrounding scene, and display the captured scene in real time via an AR display system, and may magnify or modify the displayed scene to aid in enhancing the vision of a low-vision user. Taking the above-mentioned usage mode of the low-vision user when going up and down stairs ("stair working mode") as an example, the low-vision user can see the stairs and the contour lines superimposed and displayed on the stairs through the display screen of the vision-aid glasses, so as to enhance the vision of the low-vision user when going out outdoors to improve personal safety. The two-dimensional or three-dimensional information comprises a height difference between different planes of the target object. The two-dimensional or three-dimensional information comprises contour lines such as height and width of each stair and height difference between the stairs, so that a user can feel the height difference of the stairs more visually, potential safety hazards are eliminated, and the outdoor travel safety of the low-vision user is greatly improved. In another embodiment, the display unit 103 may be a screen of a handheld smart device, such as a smartphone screen.
The visual auxiliary additional information comprises high-color difference bright display, high-color difference outline display, high-color difference character prompt and grid outline display. In an embodiment of the present invention, referring to fig. 2, when a low-vision user 300 uses the portable visual assistance device 100 of the present invention to go up and down stairs ("stair work mode"), the image acquisition unit 102 projects light on the user-selected target object of interest 200 for alerting the user, such as on three stairs below the feet (such as three steps that the user will go down when going down stairs). For example, the portable visual assistance apparatus 100 may be configured to select the target object by the user 300 pointing the portable visual assistance apparatus 100 and/or the image acquisition unit 102 at the target object 200. The three steps of stairs all present a light display showing the stair profile to show the width and height of each step of stairs. In one embodiment, the portable visual aid 100 is configured to display adjacent stairs on the stairs in different colors and/or patterns. In one embodiment, the first stair may display a yellow grid-shaped outline on the stairs, the second stair may display a blue grid-shaped outline, the third stair is the same as the first stair and also displays a yellow grid-shaped outline, and thus the difference prompt of the yellow and blue grid intervals reminds the low-vision user to improve the safety of going up and down the stairs. In other embodiments, the differential cues may also be displayed in other different colors or pattern intervals on different steps.
Referring to fig. 3, after the user goes down a stair, the portable visual assistance device 100 still continues to work, and similarly, a yellow grid profile, a blue grid profile and a yellow grid profile are displayed on three stairs below the user's feet at the same time, so that the eyesight and the safety of the low-vision user are improved by distinguishing each stair step, and the outdoor travel requirement of the low-vision user is met.
It should be understood that in other embodiments, the portable visual assistance apparatus 100 may be configured to display visual assistance additional information on steps other than three. In one embodiment, the portable visual assistance apparatus 100 may be configured such that at least two steps display visual assistance additional information (e.g., two steps display grid outlines of different colors). In another embodiment, the portable visual assistance apparatus 100 in other embodiments may be configured to display visual assistance additional information in at least three steps (e.g., three steps are illuminated and display a grid outline of a different color, four steps are illuminated and display a grid outline of a different color, etc.).
In an embodiment of the present invention, the visual auxiliary additional information displays a high-aberration profile display, and the two-dimensional or three-dimensional information of the target object 200 acquired by the image acquisition unit 102 includes a height difference in a vertical direction (such as a height direction of a staircase) between steps of a multi-step staircase and a step where the user is located. When the height difference of any one step is smaller than a preset safety threshold, the safety prompt is displayed on the step of the step; and when the height difference of any one step is greater than a preset safety threshold value, the danger prompt is displayed on the step. Referring to fig. 4, for example, setting the safety threshold to 25cm, only the next step closest to the user is less than 25cm from the step where the user is located, and in one embodiment, the safety alarm and the danger alarm may be implemented by displaying different colors on the steps. For example, one step displays a security alert in a first color (e.g., green) and a hazard alert in a second color (e.g., red) on the next step. For example, only the next step nearest to the user is displayed with a green grid outline, i.e., a safety cue, while the other steps below are displayed with red grid outlines, i.e., danger cues.
Referring to FIG. 5, the user continues to work with his portable visual aid after the next stair, and likewise, the green grid outline, the red grid outline, and the red grid outline are displayed sequentially on the third stairs below the user's feet. The user only needs to walk to the step where the green grid outline is located when going downstairs according to the prompt of the visual auxiliary additional information, and then the user can safely go downstairs. In other alternative embodiments, the safety and hazard cues may also be in the form of a font or pattern or an audible alert, a vibratory alert, or a combination of any two or more thereof. The flashlight shape of the drawings of fig. 2-5 is one embodiment of the portable visual aid of the present invention, it is to be understood that the shape/form of the portable visual aid 100 can also be other shapes or structures such as a necklace, glasses, hat, or wearable on the human body and is not limited to the shape or structure shown.
In an embodiment of the present invention, the visual auxiliary additional information includes two-dimensional or three-dimensional information of the target object and horizontal distance information between the target object and a user. For example, when the low-vision user goes out at night and uses the portable visual aid of the present invention, the image capturing unit 102 projects light forward to illuminate an object in front of the user, such as a door frame, and the display unit 103 displays the outline of the door frame on the door frame in reality in an overlapping manner and displays the horizontal distance between the door frame and the user. If a plurality of objects are in front of the intelligent planning system, the user can be prompted to walk on the route of the objects which do not block the traveling, namely, the intelligent planning of the safe traveling route of the user is facilitated.
