Description

  The present invention relates to a vehicle projection system and a program for projecting data acquired by sensing in a vehicle onto a projection target in the vehicle and allowing a user to visually recognize the image.

  For example, in-vehicle electronic devices such as navigation devices and microwave receivers (radar detectors) process position information related to driving acquired by a built-in receiving device and provide it as image information that can be viewed by the user. As a providing means, one using a monitor device such as a liquid crystal display is generally used, but there is one provided by projecting to a predetermined position by an image projection method as disclosed in Patent Document 1.

Utility Model Registration No. 3078359

In the image projection method of Patent Document 1, an image is projected on the windshield C2 from the display device 10 placed on the dashboard C1, and the user visually observes the projected virtual image. As described above, the image projection method does not necessarily require a monitor device, so that the driver's field of view can be prevented from being hindered by the presence of the monitor device. In addition, problems relating to fixing of the monitor device and wiring of the power supply to the monitor device can be solved.
However, in the conventional image projection method, when a certain position is set as a projection position as in Patent Document 1, it is only possible to project an image only at that position, and the projection position cannot be easily changed. The advantage of the image projection method that should be able to project to various places could not be fully utilized.
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a vehicle projection system capable of selectively projecting images to a plurality of locations and a program thereof. .

In order to achieve the above object, according to the first aspect of the present invention, a projection unit that projects an image onto a projection target, and an image based on data obtained by sensing in a vehicle as an image projected by the projection unit. And a control unit for generating the projection unit, wherein the projection unit has a function of changing a projection position of the image, and the control unit is configured to perform projection based on the data obtained by the sensing. The gist of the invention is to control the projection location of the image projected.
With such a configuration, it is possible to project images based on data obtained by sensing in the vehicle via the projecting means at different positions. Specific examples of the projection means include a high-intensity LED as the light source, and a liquid crystal projector, a DLP projector, an LCOS projector, and the like as the video source. The power source may be either a secondary battery (battery) or a vehicle DC12V power source. Moreover, you may make it charge a secondary battery with a solar power generation unit (solar panel).
Specifically, the “control of the projection location” performed by the control means is, for example, changing the size of the projection image or changing it to a projection position that is easy to see in an outside light situation where the brightness changes such as day and night. Can be mentioned. Changing to a projecting position that is easy to see in an external light situation is, for example, projecting to an easy-to-see position (for example, the center) of the steering when it is bright (for example, daytime) and projecting to the windshield if it is dark (for example, at night). The projection means performs such a controlled projection under the control of the control means at different projection locations. The user can set the size of the projected image, conditions for changing the brightness, and the like.

Here, examples of the “vehicle projection system” include an electronic device including a casing and a projector such as a fuel consumption display device, a radar detection device, and a navigation device. Further, the projector may be integrated with the housing, or may exist as a separate projector that outputs data from the control means wirelessly or by wire. The “control unit” may be composed of a single control unit or a plurality of control units. As a function, for example, when projecting an image, it is preferable to have a configuration for recording sound, and when projecting a map, an icon is also displayed. Further, for example, a function of recording / reproducing music data may be provided, and GPS NMEA data may be included or stored in association with the recording.
The target on which the image is projected is not particularly limited as long as it is an exposed surface in the vehicle and can be projected from the projection unit. In particular, the reflecting surface for projecting the image may be arranged at a position where it is desired to be projected. Further, instead of projecting directly on the exposed surface in the vehicle, for example, a panel body having a region for projection may be fixed in the vehicle and projected onto the panel body. Further, for example, it may be projected onto a window or projected onto a generated clouded gas. In addition to directly viewing the projected image, for example, the image may be projected on the rear window and reflected on the rear-view mirror so as to be indirectly viewed.

According to a second aspect of the present invention, in addition to the first aspect of the invention, the projection unit is configured to change the projection location of the image by changing the projection direction to a physically different state. Is the gist.
This is a more specific expression of the “function of changing the projection location of the image of the projection unit” in claim 1, and the state in which the projection direction is physically different is, for example, the direction of one optical system. It is preferable to adopt a configuration in which the control unit controls and changes the projection location, or has a plurality of optical systems with different orientations, and each optical system projects an image according to the situation under the control of the control unit.

According to a third aspect of the invention, in addition to the first or second aspect of the invention, an alarm image is provided as the image, information relating to the importance of the alarm is provided as data obtained by the sensing, and the control means The gist of the invention is to control the projection location so that it becomes easier to enter the driver's field of view as the importance of the alarm increases.
As a result, for example, the user can instantly recognize a change in the importance level by visually observing the state in which the projected portion moves as the importance level of the alarm increases. It is preferable that the user can set at what timing the projection location is moved. For example, the setting of the distance to the alarm target corresponding to the projection location can be set. When projecting an image, for example, voice or music can be accompanied. In order to express the degree of urgency when the importance level of the alarm becomes high, it is preferable to increase the sound level, make the music more anxious, or increase the performance speed. Examples of the importance level of the alarm include the type of alarm, the level of alarm, and the distance to the alarm target.

In the invention of claim 4, in addition to the invention of any one of claims 1 to 3, the image is provided with an alarm image, and the control means provides data up to the alarm object as data obtained by the sensing. The gist of the invention is to control the projection location so that the projection location becomes easier to enter the driver's field of view as the distance becomes shorter.
As a result, as the distance to the alarm target that requires more attention is getting closer, the projected location becomes closer to the driver's field of view, so the approach to the important alert target is reflected in the approach of the projected location. Thus, the driver (user) can realistically recognize the degree of approach to the alarm target, so the effect of alerting the user is greatly increased.
When projecting an image as described above, it is preferable to accompany sound and music. In order to express the degree of urgency of approaching the alarm target as the voice and music approach, it is possible to make the sound louder, make the music more anxious, or increase the performance speed. Still good.

In the invention according to claim 5, in addition to the invention according to any one of claims 1 to 4, when the image includes a single color image and the data obtained by the sensing satisfies a predetermined alarm condition The gist of the invention is to control the projection unit to project the monochrome image while changing the projection location.
As a result, a warning with a sense of urgency can be provided. When a given alarm condition is met, for example, when the importance of the alarm becomes high, such as when the distance to the alarm target is short, for example, it is important for the user to emit red, yellow, green, or other single color light The change in the degree can be recognized. In this case, only one single color may be continuously projected, or may be projected by the rotating means so as to flicker, for example, like a rotating lamp. With such a flickering projection method, light is projected while moving on the ceiling, pillar, etc. in the vehicle, and the feeling of urgency is further increased. Also, a plurality of single colors may be flickered by the rotating means. When a plurality of single colors are prepared, different colors may be projected while changing the projection location in order to express the degree of urgency of approaching the alarm target.
In the invention according to claim 6, in addition to the invention according to any one of claims 1 to 5, when the data obtained by the sensing satisfies a predetermined alarm condition, The gist is to perform control to change the brightness of the image.
As a result, when a predetermined alarm condition is satisfied, for example, when the importance of the alarm becomes high, for example, when the distance to the alarm target is short, for example, the projected image blinks or is strongly lit as a flashlight. By doing so, the user can be made aware of the importance and the change in importance.
In the invention according to claim 7, in addition to the invention according to claim 5 or 6, the control means performs control for notifying an alarm from a notifying means different from the projecting means while changing the projection location. The gist is to do.
As another notification means, for example, a speaker device that emits sound can be cited, and it is assumed that sound notification according to importance is performed under a predetermined alarm condition. This sound notification may be the same sound from beginning to end even if the projection location is changed, and the type of sound (for example, the pitch, loudness, rhythm, etc.) is changed every time the projection location is changed. It is also possible.

In the invention according to claim 8, in addition to the invention according to any one of claims 1 to 7, the control means determines a security risk to the vehicle based on the data obtained by the sensing, and security. When there is a risk, the gist is to control the projection means to project the image while changing the projection location.
For example, the projection location may be a random position, or when it is determined that there is a security risk, the projection location may be projected to a projection location according to the security risk. In this way, it will help to eliminate security risks such as repelling bandits. A security risk is an unnatural access to a vehicle. For example, when abnormal vibration is applied to the vehicle, it is detected by a detection means and is directed outward (for example, a windshield and left and right windows). It is assumed that the projection is performed. As a result, a function as a so-called repelling light that drives away a suspicious person such as an on-vehicle aim can be exhibited.

In the invention according to claim 9, in addition to the invention according to any one of claims 1 to 8, the control means includes data relating to a driver's fatigue degree as data obtained by the sensing, and the fatigue. When the degree exceeds a predetermined reference, it is configured to control the projection means to project the image while changing the projection location, and includes the position of the driver as the projection location. To do.
If it is determined that the driver is fatigued, the degree of fatigue exceeds a predetermined standard, for example, is projected onto the driver himself, for example, by projection means. It is supposed to prevent. For example, data related to the degree of fatigue is taken when the driver's face is photographed over time with a camera, and when the closed state of the eyelid is detected from the facial expression information and a closed state of a predetermined time or more is detected, It is possible to obtain the information with various known configurations, such as determining the possibility, or determining the fatigue state by detecting an electroencephalogram while wearing the electroencephalogram detection head electrode.

In the invention according to claim 10, in addition to the invention according to any one of claims 1 to 9, the control means converts the image deformed by the inclination of the surface of the projected portion into the undeformed image. The gist of the invention is that the image processing apparatus includes a correcting unit for correcting the projected image so as to be close, and causes the projecting unit to project the image corrected by the correcting unit.
The projection location in the vehicle is not a plane, and the projection image from the projection means is not necessarily projected so as to face a certain plane. Therefore, the projected image is recognized as a deformed image when viewed from the user as it is. In this way, it is possible to provide an image that is easy for the user to visually recognize by correcting the image direction so that it is not deformed.
According to an eleventh aspect of the present invention, in addition to the tenth aspect of the present invention, the control means is a memory that can extract correction data for correcting the projection image for each projection location of the image from outside. The gist is to memorize the means.
As a result, even after the power is turned off once, when the power is turned on again, it is possible to project a projection image corrected based on past correction data so that an optimal projection image is obtained each time. There is no need for correction by correction means. The recording means can be a card medium in addition to a hard disk, and the card medium may be an external medium via an interface such as USB, HDMI, IEEE 1394, or the like. These storage means can be arbitrarily read or written.

In this way, the video data captured by the camera can be captured. For example, the content of the video (image) can be confirmed in real time or after the stored data is called up later. Furthermore, the recording unit may record data based on the video data so as to serve as a drive recorder. Further, as will be described later, it can also be used for photographing a user's face and acquiring the coordinates of the operator. As a camera, a CCD camera or a CMOS camera is preferable for miniaturization.

According to a thirteenth aspect of the present invention, in addition to the invention according to any one of the first to twelfth aspects of the present invention, the control means is configured to perform the sensing of the data obtained by the sensing or the image based on the data obtained by the sensing. The gist of the invention is to record at least one of the information about the projection location at the time of sensing in a recording unit capable of extracting information from the outside.
This makes it possible to store data and images obtained by sensing and use them appropriately. The data obtained by sensing includes music data in addition to the video data. Images include moving images and still images. The recording means is preferably, for example, a card medium such as an SD card in addition to a hard disk, and the card medium may be an external medium via an interface such as USB, HDMI, IEEE 1394, or the like. Further, it may be recorded in a server or the like connected by wireless communication or the like. These storage means can be arbitrarily read or written.

It is possible to specify the mutual time relationship between different types of data, and the information is recorded in a recording means from which information can be extracted from the outside, and the relationship between the information recorded in the recording means and the data obtained by the current sensing The gist is to generate the image based on the nature.
As a result, the data acquired by sensing in the past is collated with the data acquired by sensing the present time, for example, an image indicating whether the current location is close to the location taken in the past is generated. You can check the approach to the place where you took the photo.
Here, the “plurality of types of data” specifically includes, for example, image data (including video data), audio data, GPS (time, latitude, longitude, etc.) data, and the like. Examples of the sensing means include a camera for acquiring image data, a GPS (Global Positioning System) for acquiring GPS data, a microwave receiver for receiving microwaves, and a wireless receiver for receiving radio waves. . For example, it is preferable to display an icon on a map displayed on the current screen or to notify by voice whether or not the place has been taken in the past. As for the place where the image was taken in the past, it is based on predetermined shooting conditions (for example, data based on GPS data as in the case of approaching a certain POI position, or data in which the user pressed the shooting button in the past and detected the pressed state at that time. And the like.

As a result, when there is a predetermined approach relationship with the current position in relation to past position data or audio data, it is notified by at least one of image or audio, so it can be confirmed by image or audio. .

According to a sixteenth aspect of the invention, in addition to the invention according to the fourteenth or fifteenth aspect, the plurality of types of data includes data on a current position of a vehicle and other types of data other than the data, The means records the other type of data in the recording means so that the current position can be specified when the data meets a predetermined recording condition, and the current position of the vehicle and the current vehicle current recorded in the recording means are recorded. The gist of the invention is to generate the image including an icon indicating that the recorded other type of data exists when the position is in a predetermined approaching relationship.
Thereby, for example, road information around the current position can be projected as a map screen together with the current position.
As a result, for example, when a position where another type of data recorded in conformity with a predetermined recording condition is obtained is near the current position, this can be indicated on the current map by an icon. It is possible to recall the past recording history.
Here, “other types of data” includes visual data such as moving images and still images.
According to a seventeenth aspect of the present invention, in addition to the sixteenth aspect of the present invention, the control means displays an icon indicating a current position of the current vehicle with respect to a road image around the current position of the current vehicle. The gist is to generate the image in such a manner that the positional relationship of the icon indicating that the other type of data exists can be recognized.
As a result, when a position where another type of data recorded in accordance with a predetermined recording condition in the past is obtained is near the current position, the icon is displayed when the position is indicated on the current map by an icon. And other icons can be displayed on the screen so that they can be clearly distinguished.

In addition to the invention in any one of Claims 1-17, in the invention of Claim 18, the said projection means is a relatively bright location and a dark location in the state which does not project as the said projection location. The control means includes data relating to brightness in or around the vehicle as data obtained by sensing, and determines whether to project to the bright spot or the dark spot according to the brightness. This is the gist.
In this way, since either one of the bright and dark portions can be selected, it can be projected onto a more suitable projection portion depending on the brightness situation. For example, when the outside is bright during the day, the screen is placed in the center of the relatively dark steering and projected there, and when it gets dark at night, the steering may not be necessary. It is assumed to be projected onto the windshield. When switching the projection location depending on the brightness, the bright and dark locations may be stored in advance, and the relatively bright and dark locations may be stored in advance, or the user may change and set as appropriate. It is good also as a possible structure.

According to a nineteenth aspect of the present invention, in addition to the invention according to any one of the first to eighteenth aspects of the present invention, the vehicle is provided with input means that can be input in a state where the driver of the vehicle is seated in the driver's seat, The gist of the present invention is to perform control related to the image based on the input from the input means.
By providing the input means that can be input even when the driver is seated in the driver's seat, it is possible to give an instruction to the control means even when the control means is at a separated position.

Although light in such a band cannot be seen with the naked eye, it can be projected on a screen and made visible by wearing dedicated glasses. As a result, for example, only the driver wearing dedicated glasses can see invisible light information without being known to the passenger. For example, if a radar detection device warning is displayed as invisible light while watching a movie or TV as an image using visible light as a light source, only the driver wearing dedicated glasses can know this warning. It becomes possible. Usually, an image using visible light as a light source is viewed, and an image using invisible light as a light source is inserted here, but the reverse is also possible.
The invention according to claim 40 is characterized in that, in addition to the invention according to claim 39, the simultaneously visible projection locations are the same projection location.
In other words, an image using visible light as a light source and an image using invisible light as a light source are visually recognized by a person wearing dedicated glasses. As a result of the overlap, it is possible to detect that some information has been instantly transmitted to a person wearing dedicated glasses.
The gist of the invention described in claim 41 is that it is a program for causing a computer to realize the function of the control means in the in-vehicle projection system described in claims 1-40.

  According to the present invention, since an image can be selectively projected to a plurality of locations, the projection location can be changed according to the situation, and the advantages of the image projection method can be fully utilized. .

As shown in FIG. 4, the main body 11 is supported by a first rotation shaft 17 so as to be rotatable relative to the stand 12. The main body 11 is rotated with respect to the stand 12 by the first servo motor 18, and the optical axis direction of the projector unit 15 (the direction in which the projection lens 16 faces) is rotated with the first rotation shaft 17 as the main body 11 rotates. Displace around. In the main body 11, the projector unit 15 is supported by a second rotation shaft 19 that is orthogonal to the first rotation shaft 17. The second rotating shaft 19 is rotated by the second servo motor 20, and the projector unit 15 is rotated with respect to the main body 11 together with the second rotating shaft 19, and the optical axis direction of the projector unit 15 is changed. It is displaced around the second rotation axis 19.
As shown in FIG. 1 (b), a power switch 21 and a slot 22 for inserting an SD card are formed on the side surface of the main body 11, and an audio hole 23 for transmitting the sound of the speaker device 45 to the outside is formed on the upper surface. An infrared light receiving unit 24 is formed. An insertion hole 25 for a DC power jack is formed in the stand 12. Although not shown in the drawings, in this embodiment, the power source on the main body side of the radar detection device 10 is obtained from a cigar socket (that is, a secondary battery that is a vehicle battery) and can be charged to a battery (not shown) inside the main body 11. And

  The radar detection device 10 according to the first embodiment is configured such that an image can be projected by the projector unit 15 at three positions set in advance. Hereinafter, these three projection directions are referred to as first to third projection directions. As shown in FIGS. 1 and 2, first to third reflective films 26 </ b> A to 26 </ b> C serving as projection screens are attached to the projection surfaces in three appropriately spaced vehicles corresponding to the projection directions. Yes. The first to third reflective films 26A to 26C are diffusion-type opaque films. In the first embodiment, the first reflective film 26A is disposed on the front surface of the dashboard D on the passenger seat side, and the second The reflective film 26B is disposed on the front surface of the dashboard D close to the instrument panel on the driver's seat side, and the third reflective film 26C is disposed on the front surface of the dashboard D facing the driver at the front position of the steering wheel S. . The first to third reflective films 26 </ b> A to 26 </ b> C can be arranged at arbitrary positions according to the user's request as long as they can be viewed from the radar detection device 10, that is, can be projected. is there. As will be described later, the user sets so that an image is projected from the projector unit 15 at the positions of the first to third reflective films 26A to 26C (after setting, the first to first projection directions (projection locations)). You may make it stick the 3rd reflective films 26A-26C).

The radar detection device 10 includes an operation surface remote control device 27 as shown in FIG. The remote control device 27 includes a housing 28 having a flat and extremely thin outer shape. An infrared light emitting unit 35 is formed at the upper end of the housing 28. On the surface of the housing 28, first to third projection direction setting buttons 29 to 31 for setting a projection direction, a horizontal direction rotation button 32, a vertical direction rotation button 33, keystone correction buttons 34 a to 34 d, A confirmation button 36 and a mode button 38 are formed. A holder (not shown) for accommodating a lithium battery as a power source is formed on the back surface of the housing 28.
The first to third projection direction setting buttons 29 to 31 are button switches that are pressed to set three projection directions, respectively. The left / right direction rotation button 32 is a button switch used when the main body 11 is rotated relative to the stand 12. The vertical rotation button 33 is a button switch used when the projector unit 15 is rotated up and down together with the second rotation shaft 19. The trapezoidal correction buttons 34a to 34d are used to correct the projected image as close to a normal image as possible without distortion when the projection surface is not orthogonal to the optical axis to be projected or is not a plane. This is a button switch for performing so-called keystone correction. The confirmation button 36 determines the projection direction by using the left / right direction rotation button 32 and the up / down direction rotation button 33, corrects the projection image by the keystone correction buttons 34a to 34d, and then confirms the projection direction. It is a button switch used for this purpose. The mode button 38 is a button switch used for setting various modes.
In the present embodiment, IrDA standard infrared data modulated using the remote control device 27 is wirelessly transmitted from the infrared light emitting unit 35 to the infrared light receiving unit 24 of the radar detection device 10, and setting of the radar detection device 10 as the main body is performed. Instruct the mode change.

Next, an electrical configuration inside the main body 11 of the radar detector 10 will be described based on the block diagram of FIG. In addition, about the structure which is not directly related to this invention, it abbreviate | omits.
The controller MC as the control means includes a position detector 37, a microwave receiver 38, a wireless receiver 39, a remote control receiver 40, a memory card reader 41, a database 42, first and second rotary encoders 43 and 44, The projector unit 15, the speaker device 45 as notification means, and the first and second servomotors 18 and 20 are connected to each other.
The controller MC includes a known CPU, a memory such as a ROM and a RAM, a timer, and the like. The map data is called into the ROM of the controller MC and is projected on the projector unit 15 in association with the obtained target data and the detection data of the speed measuring device (mobile radar or the like (hereinafter simply referred to as “radar”)). Map projection program, projector control program for controlling DMD and light source of projector unit 15, correction program for correcting image data to be projected, servo motor drive control for controlling driving of first and second servo motors 18 and 20 A program, a GPS information processing program for processing GPS information received by the GPS receiver 45, a microwave determination program for determining a microwave received by the microwave receiver 38, and a radio wave received by the wireless receiver 39 Radio wave judgment program to judge OS (Operation System), such as various programs are stored.

The position detector 37 as the current position acquisition means includes a GPS receiver 45 as a known time acquisition means for acquiring GPS information as the core of the configuration. The current time is determined by the GPS receiver 45 based on an instruction from the controller MC. The position of the own vehicle at is detected. The detected position information is the speed, latitude, longitude, and altitude of the vehicle. The microwave receiver 38 detects a predetermined microwave from the received microwave. The radio receiver 39 detects a predetermined radio wave from the received radio wave. The remote control receiver 40 receives the infrared data output from the remote control device 27 via the infrared light receiver 15 and demodulates it. The memory card reader 41 reads data of an SD card as a memory card inserted into the slot 22 or updates the data of the SD card.
The database 42 is a non-volatile memory (for example, EEPROM) in the controller MC or externally attached to the controller MC. In the present embodiment, the database 42 includes main roads, main facilities (for example, service areas, parking areas, highway oasis, road stations, parking lots, etc., which will be described later), main traffic systems (for example, N system, loop coils which will be described later). , LH system, radar-type orbis, etc.) target position data and map data (schematic diagram and photograph data) are stored in association with audio data.
The first rotary encoder 43 measures the amount of rotation of the first rotation shaft 17 rotated by the first servomotor 18, and the second rotary encoder 44 is rotated by the second servomotor 20. The amount of rotation of the second rotation shaft 19 is measured. The controller M determines the projection direction of the projector unit 15 from the reference direction (the direction in which the projection lens 16 faces) based on the measurement values of the first and second rotary encoders 43 and 44.

In such an electrical configuration, the controller MC executes functions such as a GPS alarm function, a radar wave alarm function, and a radio alarm function, which are basic functions of the radar detector 10. In this embodiment, the priority of each function is set in order of the radar wave alarm function, the radio alarm function, and the GPS alarm function from the highest, but the priority can be changed.
In this embodiment, the controller MC associates the current position data detected by the GPS receiver 45 every second with the detected time and speed (vehicle speed), and the SD card connected to the memory card reader 41 as a position history. To record. This position history is a function of recording in the NMEA format, for example.

In addition, the controller MC controls the projector unit 15 to execute brightness adjustment and blinking control of a high-brightness LED built in when projecting a predetermined image, drive control of a digital mirror device (DMD), and the like. Further, the image data is corrected based on the input from the user's keystone correction buttons 34a to 34d. The pressing time of the correction buttons 34a to 34d is set corresponding to the deformation amount of the image data, and the controller MC deforms the image data based on the pressing position and the pressing time of each correction button 34a to 34d. By pressing the correction buttons 34a to 34d, the image data is corrected in conjunction with each other. Therefore, the user can visually check the image projected by the demo and project the image with the correction buttons 34a to 34d so that the shape is the most visible. Will be corrected.
The deformation method is as follows. In the first embodiment, as shown in FIG. 7, a non-distorted projection screen A0 projected with image data correctly faced is assumed. Then, a projection image A that is not directly facing is assumed (in practice, this is a complex deformation in which a shape element that is not necessarily a plane at the projection location is added). The idea is to perform correction on the image data so as to cancel this distortion in order to correct the projection image A that is not directly facing the driver as seen from the driver to a screen such as the projection screen A0. For example, when the projected image is enlarged and projected as a broken line with respect to the normal image as shown in FIG. 8A, the image data indicated by the solid line is displayed in order to correct this to the original rectangular shape. As shown in FIG. 8 (b), it is necessary to correct the image data so as to cancel the enlargement direction. That is, if the image data is corrected, the corrected image data is reflected in the projection image. Therefore, the correction buttons 34a to 34d are operated by causing the user to actually view the projection image and operating the correction buttons 34a to 34d. The projection image is corrected by correcting the image data linked with 34d.

The controller MC executes the GPS alarm function at a predetermined timing (for example, at intervals of 1 second). The controller MC obtains the distance between the latitude and longitude data of the target stored in the database 42 and the latitude and longitude data of the current position detected by the GPS receiver 45, and the obtained distance becomes a predetermined approach distance. Then, the projector unit 15 is caused to perform a projection operation, and at the same time, an approach warning sound indicating that is output from the speaker device 45. In the first embodiment, the controller MC starts projecting an image in the first projection direction when the distance of the target is within 1 km, and projects the image from the first projection direction to the second projection direction when the distance is within 500 m. When the distance is within 150 m, the projection of the image is moved from the first projection direction to the second projection direction. Then, when passing the target, the projection operation is terminated. In the first embodiment, the controller MC drives the first and second servomotors 18 and 20 based on the measurement values of the first and second rotary encoders 43 and 44 with the first projection direction as the reference direction. . The controller MC rotates and vertically swings the main body 11 in order of the second projection direction and the third projection direction based on the measurement values of the predetermined first and second rotary encoders 43 and 44 to project the projection direction (projection). The direction in which the lens 16 faces) is moved, and when the vehicle passes the target, it is returned to the first projection direction.
Specific targets include snoozing driving accident points, radar, speed limit switching points, control areas, inspection areas, parking monitoring areas, N systems, traffic monitoring systems, intersection monitoring points, signal ignorance suppression systems, police Station, accident-prone area, frequent on-vehicle area, sudden / continuous curve (highway), branch / merge point (highway), ETC lane advance guidance (highway), service area (highway), parking area (highway Road), highway oasis (highway), smart interchange (highway), gas station (highway) in PA / SA, tunnel (highway), highway radio reception area (highway), prefectural border notice, road station, Viewpoint parking and the like.

For example, when approaching a service area while traveling on an expressway and determining that the acquired position information data is within a predetermined range with respect to the position of the service area of the map data, as shown in FIG. A schematic diagram or photograph of color display that can be understood from the relationship with the position of the image is read from the database 42 according to the distance from the projector unit 15 to the first to third projection directions, that is, the first to third reflection films 26A to 26C. At the same time, the voice data stored in the database 42 is read out, and voice notification such as “1 km ahead, highway service area” is given from the speaker device 45. The sound notification is performed in synchronization with the start of projection in the first to third projection directions.
In addition, if the target is an important alarm target that cannot be ignored, the controller MC, for example, snooze driving accident point, radar, speed limit switching point, control area, inspection area, N system, traffic monitoring system, intersection monitoring point In the case of the signal ignoring suppression system, when the second projection direction is reached, the red single-color projection in which the digital mirror device (DMD) of the projector unit 15 is controlled from the projection color of the normal color scheme to form an image of only red. In the case of the third projection direction, the red single-color image is flashed and projected for stronger attention.

The controller MC executes a radar wave warning function based on detecting a signal corresponding to a microwave of a predetermined frequency band emitted from the radar from the microwave receiver 38. When it is determined that the microwave receiver 38 has detected a predetermined microwave, the controller MC outputs an alarm sound from the speaker device 45.
When the microwave is detected, the controller MC reads out the voice data stored in the database 42 according to the wavelength of the microwave and causes the speaker device 45 to output an alarm voice. For example, when a control radio is received, a voice notification such as “I will soon be an H system” is made.
The controller MC executes a wireless alarm function for issuing an alarm when the wireless receiver 39 receives a radio wave emitted from an emergency vehicle or the like. In the radio alarm function, the control radio, car radio, digital radio, special radio, police radio, police phone, police activity radio, wrecker radio, heli tele radio, fire helicopter radio, fire fight radio, emergency radio, expressway radio When the radio frequency is scanned at the scanned frequency, the controller MC reads out the voice data stored for each radio type in the database 42, and the type of the radio is read from the speaker device 45. Alarm sound indicating is output. For example, when a control radio is received, for example, a sound such as “a control radio. Speed attention” is output.

In the configuration as described above, first, a setting operation in which the user uses the remote control device 27 to set the positions at which the first to third reflective films 26A to 26C are attached to the first to third projection directions, respectively. Will be described. Here, as an example, an operation for setting the first projection direction (the position where the first reflective film 26A is attached) will be described.
When the user operates the remote control device 27 and presses the first projection direction setting button 29, the controller MC causes the projector unit 15 to execute demonstration projection. The user operates the left / right direction rotation button 32 and the up / down direction rotation button 33 while confirming the projection position, and moves the image of the demonstration projection while rotating or vertically swinging the main body 11, and the first reflection is performed. A first projection direction is determined on the film 26A. Next, the trapezoidal correction buttons 34a to 34d are operated so that the demo-projected symbols can be adjusted so that they can be seen as much as possible from the driver (the shape of the image is corrected). When the confirm button 36 is pressed, the controller MC stores the current measurement values of the first and second rotary encoders 43 and 44 and the correction amount of the image data for the keystone correction. It is assumed that the same operation is performed by the remote controller 27 for the other two projection positions.

Next, in the radar detection device 10 having such a configuration, an example of control of the controller MC when projecting images onto the first to third reflection films 26A to 26C in an actual traveling state is based on the flowchart of FIG. I will explain. Note that the routine of the first embodiment is executed at a timing of 100 ms.
First, the controller MC obtains the distance between the latitude and longitude data of the current position acquired by the GPS receiver 45 in step S1 and the latitude and longitude data of the target stored in the database 42, and is approaching the target. It is determined whether the distance is within 1 km and far from 500 m. If it is determined that the vehicle is approaching the target, is within 1 km, and is far from 500 m, the controller MC determines whether or not the flag is “1” in step S2. This determination is to determine whether or not the projection onto the first reflective film 26A has already been started. If the flag is “0”, the projection is not yet performed, and the flag is “1”. In other words, it is determined that the projection has started. If the controller MC determines that the flag is “1”, the routine is temporarily terminated because the image is currently being projected.

On the other hand, if it is determined in step S2 that the flag is not 1, that is, 0, the controller MC controls the projector unit 15 in step S3 to project a normal color image on the first reflective film 26A, and at the same time, Make voice alerts. In step S4, the flag is set to “1” and the routine is temporarily ended.
On the other hand, if it is determined in step S1 that the target is approaching and within 1 km and not far from 500 m, the controller MC is approaching the target in step S5 and within 500 m and It is determined whether the distance is longer than 150 m. If the controller MC determines that the target is approaching, within 500 m, and far from 150 m, the controller MC determines whether the flag is “1” in step S <b> 6. This process is for the same reason as in step S2, and if the flag is “0”, the projection is not yet performed, and if the flag is “1”, it is determined that the projection is started. Is. If the controller MC determines that the flag is “1”, the routine is temporarily terminated because the image is currently being projected.
On the other hand, if it is determined in step S6 that the flag is not 1, that is, 0, the controller MC determines in step S7 whether the target is an important alarm target that cannot be particularly ignored. In S8, the controller MC controls the projector unit 15 to project an image of a single red projection color on the second reflective film 26B, and controls so as to give a predetermined sound notification, and the process proceeds to step S4. (That is, the flag is set to “1”) and the routine is temporarily terminated. On the other hand, if the target is not an important warning object that cannot be ignored in step S7, a normal color image is projected in step S9 and a predetermined voice notification is given. Then, the process proceeds to step S4 (that is, the flag is set to “1”), and the routine is temporarily ended.

On the other hand, if it is determined in step S5 that the target is approaching and within 500 m and not far from 150 m, it is determined in step S10 whether the target is approaching and within 150 m. If it is determined that the target is within 150 m, the controller MC determines whether or not the flag is “1” in step S11. This process is for the same reason as in step S2, and if the flag is “0”, the projection is not yet performed, and if the flag is “1”, it is determined that the projection is started. Is. If the controller MC determines that the flag is “1”, the routine is temporarily terminated because the image is currently being projected.
On the other hand, if it is determined in step S11 that the flag is not 1, that is, 0, the controller MC determines in step S12 whether the target is an important alarm target that cannot be particularly ignored. In S13, the controller MC controls the projector unit 15 to project an image of a single red projection color on the third reflective film 26C, and to control the blinking projection, and also to perform predetermined audio notification. To do.
Then, the process proceeds to step S4 (that is, the flag is set to “1”), and the routine is temporarily ended. On the other hand, if the target is not an important warning object that cannot be ignored in step S13, a normal color image is projected in step S14 and a predetermined voice notification is given. Then, the process proceeds to step S4 (that is, the flag is set to “1”), and the routine is temporarily ended.
On the other hand, if it is determined in step S10 that the target is approaching and is not within 150 m, the controller MC will notify the user that the vehicle is not within 1 km or is moving away. In step S15, the controller MC controls the projector unit 15 to end the projection, and drives the first and second servo motors 18 and 20 to move the projection lens 16 to face the first projection direction. (Return to the reference position) If the flag is “1” in step S16, this is set to “0” and the routine is terminated.
By such processing of the controller MC, the radar detection device 10 acts as follows in the vehicle. First, when the target is not close during traveling, nothing is projected onto the first to third reflective films 26A to 26C. When the target is within 1 km, the first reflective film 26A is firstly displayed. Then, the projection of the target starts, and when the distance is 500 m or less, the projection direction moves to the second reflection film 26B. Then, the projection ends when moving away from the target.

With the configuration described above, the radar detection device 10 according to the first embodiment has the following effects.
(1) The radar detection apparatus 10 has a plurality of projection directions (here, three locations) and gradually approaches a position (third projection direction) from a far position (first projection direction) depending on the degree of approach to the target. Since the projected position moves at the same time, you can get a sense of getting closer to the target and understand what the target is based on the projected image. It is possible to make the user recognize the approach to the target.
(2) When the target is an important alarm target that cannot be ignored, the projection state changes from normal color to red single color (second projection direction), and further blinks red single color (third projection direction). Therefore, the alerting function is a notification means with a very high notification capability for the user.
(3) Although it is difficult to project the projected image without deformation due to the influence of the projection direction, the shape of the projection location, etc., the user operated the correction means (keystone correction buttons 34a to 34d) and was demo-projected. Since it is possible to adjust the design so that it can be seen by the driver without being deformed as much as possible, it is practically possible to project it to various places.
(4) Since the direction of the projection lens 16 can be moved three-dimensionally, a plurality of projection directions can be arbitrarily set without having a plurality of projection means. This makes it possible to reduce the size, weight, and cost.
(5) Since the main body 11 is flat and not bulky, it can be disposed on the upper surface of the column cover 13 as described above, and does not interfere with driving.

(Embodiment 2)
The second embodiment is a variation of the first embodiment. In the first embodiment, the control is such that the first projection direction is made closer in order as the target is approached. In the second embodiment, the importance level is set in advance for the target (for example, A for an important alarm object that cannot be ignored, B for an important alarm object, and C for others). , A is the third reflection film 26C in the third projection direction close to the driver, B is the second reflection film 26B in the second projection direction, and C is the most driver. It is good also as control which makes it project on the 1st reflective film 26A used as the 1st projection direction far from.
In addition, the voice may be changed to increase the importance, and the voice may be increased, or a specific voice (music) corresponding to the projection direction may be notified. Moreover, in order to call attention more strongly as the projection method approaches, the projection method may be blinked, projected with high luminance, or projected with a single color.

Is attached to the inside of the windshield G1. The reflective film 51A is an opaque film on the diffusion side, and the liquid crystal film 51B is a transparent film that reflects only the projection light from a predetermined direction with high efficiency and transmits the other light rays. Since the image is projected from the radar detection device 10 onto the surface of the windshield G1, in the third embodiment, the radar detection device 10 constitutes a head-up display (HUD) in the vehicle.
