Can be provided.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration example of a vehicle display device 100 according to the present invention. The vehicular display device 100 includes a control unit 1, and the control unit 1 performs an imaging device 2 outside the vehicle interior and an imaging device 3 inside the vehicle via an in-vehicle network such as a CAN (Controller Area Network) or a LIN (Local Interconnect Network). , Connected to the projection device 4.

  The control unit 1 is a computer including a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), an NVRAM (Non-Volatile Random Access Memory), and the like. 11. Programs corresponding to the luminance recognizing means 12, the image recognizing means 13, the information adding means 14 and the projection control means 15 are stored in the NVRAM, and these programs are expanded on the RAM to cause the CPU to execute corresponding processes.

  The vehicle exterior imaging device 2 is a device for acquiring an image around the vehicle, and outputs the acquired image to the control unit 1.

  The vehicle exterior imaging device 2 is, for example, a CCD (Charge Coupled Device) camera or a CMOS (Complementary Metal Oxide Semiconductor) camera that is installed on the front, back, left, and right of the exterior of the vehicle, such as the body panel, bumper, front grille, and the vicinity of the license plate. It may be a fish-eye camera capable of wide-angle imaging, an omnidirectional camera, an infrared camera capable of imaging at night, or the like.

  The outside-vehicle imaging device 2 may be composed of a single camera or a plurality of cameras, may be a camera that captures moving images, and is a camera that captures still images. May be. In addition, since the vehicle exterior imaging device 2 is installed in the vehicle exterior, it may be provided with a dustproof structure or a dripproof structure.

  The vehicle interior imaging device 3 is a camera for acquiring an image in the vehicle interior, and outputs the acquired image to the control unit 1.

  The vehicle interior imaging device 3 is installed, for example, in the vehicle interior ceiling, in the vicinity of a room mirror, or in the vicinity of a projection lens of the projection device 4 described later, and images the projection range of the projection device 4. Moreover, the vehicle interior imaging device 3 is configured by a CCD camera or a CMOS camera, like the vehicle exterior imaging device 2.

  The projection device 4 is a device that projects an image onto a predetermined area in a vehicle interior. For example, a liquid crystal projector, a liquid crystal on silicon (LCOS) projector, a DLP (Digital Light Processing) (registered trademark) projector, a CRT (Cathode Ray) Tube) There are projectors.

  The projection device 4 is installed, for example, near the ceiling in the passenger compartment above the driver's seat or near the headrest of the driver's seat, receives the image information output by the control unit 1, and projects the image toward the rear of the vehicle. In this case, the projection device 4 uniformly projects an image onto an object serving as a substitute for the screen, such as a rear seat, a rear door inner wall, a rear ceiling, a rear door window, a rear glass, a pillar, and a rear seat occupant.

  Further, the projection device 4 may be pivotally attached to the ceiling so that the projection direction can be changed to the vehicle front, the vehicle side, and the vehicle rear.

  Next, various units included in the control unit 1 will be described.

  The image generation means 10 is a means for processing a scene image outside the vehicle imaged by the outside-vehicle imaging device 2 and generating a corrected image corresponding to an image viewed from the viewpoint of the driver. Based on the relative relationship between the position and the position of the projection device 4, the center point of the landscape image is moved to the left or right, or the landscape image is enlarged or reduced to generate a corrected image. Note that the image generation unit 10 may recognize the position of the driver's eyes by the vehicle interior imaging device 3 and generate a corrected image in consideration of the position of the driver's eyes.

  In addition, the image generation means 10 generates a corrected image by moving the center point or enlarging / reducing the coordinate after converting the scenery image captured by the outdoor imaging device 2 into an image without distortion.

  As a result, the vehicle display device 100 projects a corrected image that has been corrected to fit the driver's field of vision in a predetermined direction, and displays an object in a blind spot caused by a shield such as a door, pillar, inner wall, or ceiling. Can be visually recognized, so that the driver can secure a field of view as if there is no shielding object.

  The mask means 11 is a means for masking a predetermined portion of the corrected image so as not to be displayed. For example, the portion of the corrected image projected on the rear glass or the window position by the projection device 4 is masked by image processing (hereinafter, “ "Mask processing").

  The mask unit 11 performs a mask process by painting a portion to be masked (pixels indicated by XY coordinates) of the corrected image with a predetermined color (for example, black), but only the portion to be masked has a predetermined color (for example, black). The mask image displayed in () (for example, having the same image size as the corrected image) is prepared separately from the corrected image, and the corrected image and the mask image are superimposed on the mask image to perform mask processing. Good.

  The projection device 4 can prevent a part of the projection range from being irradiated by projecting the corrected image subjected to the mask process. For example, in the case of a liquid crystal projector, the projection device 4 drives a liquid crystal corresponding to a masked portion in a liquid crystal panel corresponding to each of red, blue, and green light sources so that light does not pass through the portion. To prevent projection of the masked part.

  Alternatively, in the case of a DLP (registered trademark) type projector using a DMD (Digital Micro-mirror Device) (registered trademark), the projection device 4 changes the inclination angle of the DMD corresponding to the masked portion and emits it from the light source. The emitted light is not directed in the projection direction, and the masked portion is not projected.

  The predetermined part to be masked may be a part recognized by the luminance recognition unit 12 described later or an image part recognized by the image recognition unit 13 described later. Note that the mask unit 11 may cause the operator to manually set the predetermined portion.

  The brightness recognizing means 12 is a means for recognizing a portion of the landscape image that is affected by the projection light from the projection device 4. For example, the projection recognition device 4 irradiates the interior of the vehicle with the projection light by the projection device 4. A landscape image is captured at a predetermined interval (for example, every second), and a portion of the corrected image generated based on the landscape image by the image generation means 10 is projected to a predetermined value (for example, plus 10%). It is recognized as a part affected by the projection light from the device 4.

  The increase in luminance is caused by the vehicle exterior imaging device 2 capturing an image of a portion (a part of the scenery) whose brightness has increased due to leakage of projection light from the projection device 4 through a window or the like. The projection device 4 that receives the output increases the luminance and re-projects the portion, and the outside-vehicle imaging device 2 re-images the portion (the portion where the brightness is further increased). Caused by.

  In addition, the luminance recognizing means 12 not only recognizes a portion where brightness is increased (including a time element), but also projects a portion where luminance is equal to or higher than a predetermined value (not including a time element). You may recognize as a part which receives the influence of the projection light from the apparatus 4. FIG. This is because when the above-described repetitive processing is performed, the luminance of the predetermined portion increases to the maximum value.

  Further, the brightness recognizing means 12 causes the outside image capturing device 2 to capture a landscape image while causing the projection device 4 to blink a predetermined image (for example, an image in which the entire area is white), and the image generating unit 10 converts the image into a landscape image. Of the corrected image generated based on this, a portion whose luminance changes in synchronization with the blinking of the projection device 4 may be recognized as a portion affected by the projection light from the projection device 4.

  Note that blinking of the predetermined image may be performed by turning on and off the projection by the projection device 4, or may be performed by regularly changing the luminance of the predetermined image.

  The luminance recognizing means 12 recognizes only a portion affected by the projection light from the projection device 4 and synchronizes with a projection light of the projection device 4 for a portion whose luminance is changed by a streetlight or a headlight of another vehicle. Therefore, it is not recognized as a part affected by the projection light.

  The vehicle display device 100 recognizes a portion affected by the projection light in the corrected image by the luminance recognition unit 12 and masks a portion affected by the projection light by the mask unit 11.

  This is because if the mask process is not performed, the luminance of the portion of the corrected image that is affected by the projection light becomes abnormally high and halation occurs.

  As a result, the vehicle display device 100 projects a corrected image in a predetermined direction so that the driver can visually recognize an object in a blind spot caused by a shielding object such as a door, a pillar, an inner wall, or a ceiling, but the projected light is received. Leakage to the outside from the window, windshield or rear glass can be suppressed.

  Further, since the vehicle display device 100 projects the corrected image obtained by masking the portion affected by the projection light onto the projection device 4, it is possible to prevent the occurrence of halation in the corrected image.

  Further, since the vehicle display device 100 projects the corrected image obtained by masking the portion affected by the projection light on the projection device 4, the corrected image is prevented from being projected onto the window, the windshield, or the rear glass. Further, it is possible to prevent the scenery outside the vehicle from becoming difficult to visually recognize because the actual scenery that can be visually recognized by the driver via the windshield or the rear glass overlaps with the projected corrected image.

  The image recognition unit 13 is a unit for recognizing a predetermined object in a landscape image or a vehicle interior image captured by the vehicle exterior imaging device 2 or the vehicle interior imaging device 3, and includes, for example, edge processing, γ correction, binary A predetermined object and its coordinate position are recognized by performing image processing such as conversion processing and performing matching processing using pre-registered image data.

  When the image recognizing means 13 recognizes a predetermined object from the landscape image captured by the outside-vehicle image capturing device 2, the predetermined object includes a human, animal, vehicle, curbstone, gutter, road marking, lane display, etc. Includes things that affect it.

  The image recognizing means 13 outputs the coordinate positions of these predetermined objects to the information adding means 14 described later, and highlights the predetermined objects in the corrected image or displays additional information such as the distance to the predetermined objects.

  Further, when the image recognition unit 13 recognizes a predetermined object from the vehicle interior image captured by the vehicle interior imaging device 3, the predetermined object includes a face of a passenger other than the driver, a window, a windshield, a rear glass, and the like. .

  The image recognition means 13 outputs the coordinate positions of these predetermined objects to the mask means 11 to perform mask processing so that the projection light from the projection device 4 is not projected onto the occupant's face, window, windshield, rear glass, etc. To do.

  The information adding unit 14 is a unit that acquires information about a predetermined object from the image recognition unit 13 and adds information to the corrected image. For example, the coordinate position of the predetermined object, the type of the predetermined object, the predetermined object from the image recognition unit 13 The distance between the vehicle and the vehicle is acquired, and a predetermined object (for example, a pedestrian) in the corrected image is highlighted in red, or the character “pedestrian” or a numerical value indicating the distance to the pedestrian is displayed. It is displayed near the image of the pedestrian.

  The projection control means 15 is a means for controlling the operating state of the projection apparatus 4, and for example, when the shift position is set to the “R” position, the projection apparatus 4 starts projection to the rear of the vehicle, When the direction indicator is operated, the projection device 4 starts to project obliquely forward (the traveling direction) of the vehicle, or starts projection in an arbitrary direction at an arbitrary timing by a predetermined switch operation. Note that the projection control unit 15 may always perform projection in a predetermined direction (for example, rearward of the vehicle) by the projection device 4.

  Next, a configuration example of the vehicle display device 100 in which the vehicle exterior imaging device 2, the vehicle interior imaging device 3, and the projection device 4 are arranged at predetermined positions will be described with reference to FIGS.

  FIG. 2 is a diagram showing an installation example of the vehicle exterior imaging means 2. The vehicle exterior imaging means 2 is installed on the rear license plate of the vehicle V.

  D1 to D7 indicate blind spots from the driver of the vehicle V. D1 is a right front pillar, D2 is a right center pillar, D3 is a right rear pillar, D4 is a left rear pillar, and D5 is a left center. , D6 is a left front pillar, and D7 is a blind spot area due to a door inner wall or bonnet.

  A range R indicated by an alternate long and short dash line indicates a range imaged by the vehicle exterior imaging device 2 and includes blind spots D2, D3, D4, and D7. As a result, the projection device 4 that uses the image captured by the vehicle exterior imaging device 2 is blinded by the right center pillar, the right rear pillar, the left rear pillar, and the shielding such as the door and the rear seat. The area can be projected into the passenger compartment.

  3A and 3B are diagrams illustrating an installation example of the projection device 4, in which FIG. 3A is a top perspective view of the vehicle V and FIG. 3B is a side sectional view.

  The projection device 4 is installed on the ceiling above the driver's seat, and projects an image (including a processed image) captured by the vehicle exterior imaging device 2 toward the rear of the vehicle. The projection light of the projection device 4 reaches the rear seat S, the luggage T1 placed on the rear seat S, a part of the ceiling, the inner wall of the rear door, and the rear glass W1 evenly.

  A thick line in FIG. 3 indicates a surface on which a projection image by the projection device 4 is displayed, and functions as an uneven screen.

  FIG. 4 is a diagram illustrating an installation example of the vehicle interior imaging device 3. The vehicle interior imaging device 3 is integrated with the projection device 4 installed on the ceiling above the driver's seat. The camera lens 31 is brought close to the projector lens 41 of the projection device 4 to image the entire projection range of the projection device 4. Thereby, the vehicle interior imaging device 3 can image the entire projection range of the projection device 4 without causing a large shift.

  Next, with reference to FIG. 5, processing for recognizing a portion where the luminance recognizing unit 12 is affected by the projection light from the projection device 4 will be described.

  FIG. 5A is a diagram showing a vehicle V in which the vehicle exterior imaging device 2 is installed at the rear license plate position. The vehicle V includes a projection device 4 on the ceiling above the driver's seat in the vehicle interior. 4 projects the image imaged by the vehicle exterior imaging device 2 toward the rear of the vehicle.

  Thick lines in the figure indicate the surface on which the projection light of the projection device 4 is irradiated. The projection device 4 includes the rear seat S, the luggage T1 placed on the rear seat S, a part of the ceiling, the rear glass W1, and the rear glass W1. Irradiate the luggage T2 and the like placed in front.

  There is a wall surface X behind the vehicle V, and the projection light of the projection device 4 leaking from the rear glass W1 irradiates a part of the wall surface X to generate a bright region G.

  FIG. 5B is a diagram showing an image P captured by the vehicle exterior imaging device 2, and the image P has a bright region G that floats on the wall surface X.

  The projection device 4 projects the image P to the rear of the vehicle so that the bright area G in the image P imaged by the imaging device 2 outside the vehicle overlaps the rear glass W1, and therefore receives the output from the imaging device 2 outside the vehicle and projects it. Each time the image is updated, the projection light leaking from the rear glass W1 is increased, and the brightness of the bright region G picked up by the vehicle exterior imaging device 2 is increased.

  In the vehicle display device 100, the luminance recognition means 12 increases the luminance in the image P by a predetermined ratio (for example, 10%) while a predetermined time (for example, one second) elapses after the projection device 4 starts projection. The bright area G is recognized as a portion affected by the projection light, and the mask means 11 masks the portion affected by the projection light.

  Thereby, the display apparatus 100 for vehicles can prevent that the brightness | luminance of the part which receives the influence of projection light in the image P becomes abnormally large, and a halation is generated.

  The vehicle display device 100 does not change the projection direction or the projection angle of the projection device 4 if the luminance recognition means 12 recognizes the position of the portion affected by the projection light only once at the vehicle maintenance shop or the like. As long as there is no need to update the position of the part affected by the projection light, the position of the part affected by the projection light may be updated when the engine is started or when a predetermined user operation is performed. Good.

  As a result, the vehicle display device 100 reduces the portion affected by the projection light due to the load placed near the glass so as to block the driver's view, or recognizes the portion affected by the projection light. Even when the baggage that has been placed is removed and the part affected by the projection light is expanded (referred to as returning to the original size of the window), the part affected by the projection light is recognized each time. be able to.

  In addition, even when the vehicle display device 100 does not have the wall surface X, the vehicle display device 100 can recognize a portion affected by the projection light if there is a shielding object that reflects light.

  The vehicle display device 100 recognizes not only the portion affected by the projection light leaked from the rear glass W1, but also the portion affected by the projection light leaking from the side glass, the windshield, etc., and performs mask processing. Also good.

  Next, a process in which the vehicle display device 100 generates a projection image will be described with reference to FIG.

  FIG. 6A is a view showing the scenery E1 visually recognized when the driver looks at the rear of the vehicle from the driver's seat, and is visually recognized through the rear glass W1, the side glasses W2 to W5, the rear seats S1 to S3, and the side glass W3. A pedestrian H1 is shown.

  FIG. 6B is a diagram illustrating a modified image P1 obtained by processing a landscape image captured by the vehicle exterior imaging device 2 and viewed from the viewpoint of the driver, and shows a pedestrian H1 existing behind the vehicle. . Note that a part of the pedestrian H1 (a part from the face to the shoulder) is visually recognized by the driver through the side glass W3, but the other part (the lower body part) is not visually recognized by the driver.

  FIG. 6C is a mask image P2 generated by the mask unit 11 and shows a state in which a portion affected by the projection light recognized by the luminance recognition unit 12 (shaded portion in the drawing) is masked.

  FIG. 6D shows the operation when the corrected image P1 in FIG. 6B and the mask image P2 in FIG. 6C are superimposed and synthesized, and the synthesized image is projected from the projection device 4 to the rear of the vehicle. It is a figure which shows the scenery E2 which a person visually recognizes.

  In FIG. 6D, the glasses W1 to W5 are not irradiated with the projection light from the projection device 4 by the mask image P2, and a part of the pedestrian H1 that can be seen through the side glass W3 (portion from the face to the shoulder) is shown. , Not a projection image, but a real object.

  On the other hand, the projection light from the projection device 4 is irradiated to other portions (shaded portions in the figure) including the backrest portion of the rear seat S3, and a part of the pedestrian H1 (lower body portion) The projected image is projected onto the rear seat S3 so as to be adapted to the real part of the pedestrian H1 (from the face to the shoulder) (which means establishing continuity between the real and the projected image). Projected.

  As described above, the vehicle display device 100 does not depend on the shape of the vehicle interior, and the projection device 4 projects the projected image over a wide range of the vehicle interior, but the projected light leaks out from the window portion. Suppressing and preventing the leaked projection light from adversely affecting the projected image (for example, halation) or adversely affecting external pedestrians or drivers of other vehicles (for example, dazzling). Or not.

  Next, another embodiment of the process in which the vehicle display device 100 generates a projection image will be described with reference to FIG.

  FIG. 7A is a diagram showing a vehicle interior image P3 captured by the vehicle interior imaging device 3, and includes a rear glass W1, side glasses W2 to W5, rear seats S1 to S3, an occupant H2 seated in the rear seat S1, and The luggage T2 placed near the rear glass W1 is shown.

  FIG. 7B is a diagram showing a modified image P4 obtained by processing the scenery image captured by the vehicle exterior imaging device 2 and viewing it from the viewpoint of the driver, and shows a pedestrian H3 existing behind the vehicle. . Note that the pedestrian H3 is hidden behind the luggage T2 and is not visible to the driver.

  FIG. 7C shows a mask image P5 generated by the mask means 11, and a portion (shaded portion in the figure) affected by the projection light recognized by the luminance recognition means 12 and a face portion of the occupant H2 (in the figure). The gray part) is masked. The reason for masking the face portion of the occupant H2 is to prevent the projection light of the projection device 4 from being applied to the face portion of the occupant H2.

  Here, the portion affected by the projection light (corresponding to the glass region) is recognized by the luminance recognizing unit 12 as described above, but by the image processing such as the pattern matching processing by the image recognizing unit 13, the vehicle interior imaging device. 3 may recognize the glass W1 to W5 from the vehicle interior image P3 captured and recognize the portion affected by the projection light. Note that the face portion of the pedestrian H2 is recognized by pattern matching processing or the like by the image recognition means 13.

  Further, the portion of the luggage T2 placed in front of the rear glass W1 is not included in the portion affected by the projection light, and the mask process is not performed. This is because the projection light of the projection device 4 does not leak out from the portion of the luggage T2.

  In this way, the vehicle display device 100 is affected by the projection light by the luminance recognition means 12 even when the size of the portion affected by the projection light changes, such as when a load is placed near the glass. By re-recognizing the part that receives the light, the size of the part affected by the projection light is updated, and the projected image is reliably projected onto the luggage T2 placed in front of the rear glass W1, thereby improving the driver's visibility. Can be made.

  FIG. 7D shows a case where the corrected image P4 in FIG. 7B and the mask image P5 in FIG. 7C are superimposed and synthesized, and the synthesized image is projected from the projection device 4 to the rear of the vehicle. It is a figure which shows scenery E3 which a driver | operator visually recognizes.

  In FIG. 7D, the projection light from the projection device 4 is not irradiated to the face portions of the glasses W1 to W5 and the occupant H2 by the mask image P5.

  The other portions are irradiated with projection light from the projection device 4, and the pedestrian H3 in FIG. 7D is a projection image projected by the projection device 4 so as to call the driver's attention. For example, it may be projected in a colored red color, or may be projected with a flashing “pedestrian” character L added to the periphery.

  With the above configuration, the vehicle display device 100 can display the object in the driver's blind spot in an easy-to-understand manner regardless of the arrangement, shape, size, etc. of the shielding object. It can be applied to various types of vehicles having different arrangements, shapes, sizes, etc. without changing the specifications.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. Can be added.

  For example, in the above-described embodiment, the vehicle display device 100 projects the characters “pedestrian”, the distance to the pedestrian, and the like as additional information, but may project a wire frame indicating the boundary of the vehicle. Good.
