Description

  The present invention relates to a system such as a radar detector or a car navigation system that gives predetermined information to a driver of a vehicle, for example.

Conventionally, systems such as radar detectors and car navigation systems have been widely used. This system has a function of notifying the user of the approach to an alarm target such as a speed measuring device, a control area, or an inspection area.
For example, the present applicant displays the CG (Computer Graphics) of the alarm object on the liquid crystal when the vehicle enters a predetermined approach state with the alarm object or when a microwave emitted from the speed measurement device is detected. A radar detector for displaying on display means such as a display device has been proposed (see FIG. 19 of Patent Document 1). The presence / absence of the alarm object can be notified by an alarm sound. However, according to such display, the position of the alarm object can be recognized.

In addition, there is an apparatus that displays a photograph including an alarm object such as an actual speed measuring device, a control area, an inspection area, and the like, and issues a real shooting alarm.
For example, when the vehicle approaches 1 km before the alarm object, the radar detector displays a small live-action alarm, and when the vehicle approaches 500 m before the alarm object, the radar detector displays a large real-action alarm. ing.
Also, by viewing on the display device a video data file that has been captured in advance when visibility is good, it is possible to accurately grasp the crossing position even when it is difficult to confirm the crossing position at night or when there is snow. A snowplow driving warning system that can be used is disclosed (see Patent Document 2).

JP 2009-9546 A JP 2006-44367 A

  In the radar detector of Patent Document 1 described above, a common CG corresponding to the type and contents of the speed measuring device, the control area, the inspection area, and the like is displayed and a warning is given. Therefore, the CG displayed on the screen is displayed. And the actual alert object that the vehicle is approaching. On the other hand, in the radar detector, a photograph (actual shooting alarm) including an actual alarm object approaching by the vehicle is displayed.

  However, because the conventional live-action alarm was a still image, the location of the photo including the speed measurement device does not always match the actual forward landscape that changes as the vehicle travels, and the vehicle measurement is anywhere in the forward landscape. It was difficult to identify whether there was a device.

  That is, the still image of the conventional live-action alarm is an image captured immediately before the alarm object in order to include the alarm object in the image. For example, even when the still image captured immediately before is displayed 1 km or 500 m before the alarm target, the still image does not match the front landscape. When the vehicle approaches just before the alarm object, the image of the still image matches the front landscape for the first time.

  In addition, since the live-action alarm for informing the control area, the inspection area, etc. was a photograph taken in a part of the area (for example, the center of the area), just looking at this photograph shows where the area is from. I couldn't determine the range.

  The snowplow driving warning system of Patent Document 2 is for confirming the level crossing position that is difficult to check in practice with the image of the level crossing taken when the visibility is good. It is assumed that the front landscape does not match.

Also, the crossing has a noticeable appearance in black and yellow, and if it is an image of the front scenery taken from a snowplow moving on the track at low speed, it is easy to identify where the crossing is in this image it can.
However, the scenery in front of the vehicle includes roads, other vehicles, buildings, structures such as signs and street lamps, and the vehicle moves at a higher speed than the snowplow. For this reason, it is difficult to specify a speed measuring device that is not particularly conspicuous from the scenery in front of a moving vehicle.

  The present invention has been made in view of the above-described problems, and issues a warning by using a live-action moving image corresponding to a front landscape of a moving vehicle, and indicates the alarm object in the real-vehicle moving image in an easy-to-understand manner. It is an object of the present invention to provide a system, a program, an imaging device, and software that can easily identify an actual alarm object that is approaching.

(1) In order to achieve the above object, the system according to the present invention is configured so that a vehicle is assigned a predetermined alarm object based on current vehicle position information and predetermined alarm object position information. When it is determined that the approaching state has been reached, there is provided a control means for causing the display means to display at least a live-action moving image that captures a landscape in the process of approaching the alarm target.

According to the above configuration, by displaying a live-action moving image in the process of approaching an actual alarm object and performing an alarm, the image of the live-action moving image is matched with the actual front landscape that changes as the vehicle travels. be able to. For example, when the alarm target is a speed measuring device, the user can easily specify the actual speed measuring device in the forward scenery by instructing the alarm target in the live-action video in an easy-to-understand manner. .
In addition, for example, when the alarm target is an area such as a control or an inspection, the user can display an actual area in the forward landscape by displaying a live-action video including a range from the start point to the end point of the area. It becomes possible to specify easily. According to such an in-vehicle electronic device of the present invention, it is easy for the user to specify an alarm target object, and it is possible to prompt the user to drive safely.

Here, the system of the present invention may be implemented in the form of an in-vehicle electronic device such as a radar detector or a car navigation system.
Furthermore, the system of the present invention mainly includes position information acquisition means, video data of a live-action video that captures a scene in the process of approaching an alarm object, display means of the real-time video, and control means that executes the control processing described above. Etc. can be realized.
Therefore, you may implement the system of this invention using hardware, such as a general purpose personal computer, a mobile telephone, a smart phone, and a portable game machine. In this case, software for operating these general-purpose portable terminals as the system of the present invention and video data of live-action moving pictures may be stored in a server and provided to the portable terminals via the Internet.

  In addition, the description of “actual moving image” in the present specification means a moving image obtained by capturing an actual landscape and a viewable image displayed on the display unit. In particular, even if it is not described as “video of a live-action video”, the “live-action video” means a video displayed on the display means. When referring to data instead of video, it is described as “video data of live-action video”.

(2) Preferably, positional information at the time of imaging is associated with the video data of the live-action video, and the control unit is configured to use the real-time video based on the position information of the vehicle and the position information of the video data. It is preferable to have a configuration for determining the timing for displaying the.
(3) More preferably, the control means may be configured to display the live-action moving image on the display means at a timing when the position information of the vehicle and the position information of the video data match.
(4) More preferably, the control means may be configured to display a live-action moving picture at a timing several to several tens of seconds before the current position information of the vehicle and the position information of the video data match.

  According to the above configuration, the optimal display timing of the live-action video can be determined based on the current vehicle position information and the position information when the live-action video is captured. It is possible to have an arbitrary correspondence with the landscape. In the above (1), whether or not the vehicle has approached the alarm object up to a predetermined distance is determined by, for example, the position information of the alarm object stored alone or the video data of (2) above. It is good also as a structure performed based on which of the associated positional information.

  For example, by displaying the live-action video at a timing when the current vehicle position information matches the position information at the time of shooting the live-action video, the video of the live-action video is displayed at the actual front landscape Can be matched. Thereafter, by synchronizing the playback speed of the live-action moving image with the vehicle speed, the user can easily identify the actual alarm target object by comparing the live-action moving image and the front landscape.

  In addition, for example, by displaying a live-action video at a timing several to several tens of seconds before the current vehicle position information matches the position information of the live-action video, a live-action video of a forward scene several seconds ahead of the current time Will be displayed. As a result, the user confirms the alarm object in the live-action video in advance, and then easily identifies the actual alarm object from the front landscape when the vehicle reaches the imaging point of the live-action video. Can do.

  Here, the video data of the live-action moving image in the present invention can be acquired using, for example, a dedicated imaging device in which a drive recorder is linked to a radar detector. That is, the radar detector stores the position information of the alarm target nationwide, and when the current vehicle position is in a predetermined approach relation to any one of the alarm target objects, an approach alarm is issued. The output is started and the output of the approach warning is stopped when the warning object is passed.

  On the other hand, the drive recorder is provided with buttons for starting and ending continuous recording. Therefore, a signal similar to pressing the start button is given to the drive recorder at the timing when the radar detector starts to output the approach alarm, and the drive recorder at the timing when the radar detector stops outputting the approach alarm. An imaging device is provided that gives the same signal as when the end button is pressed. By using the imaging device having such a configuration, if a warning object across the country is passed, it is possible to take a live-action moving image that extends from before the warning object passes through.

  In addition, the image captured by the drive recorder is recorded in association with vehicle position information, speed information, imaging time, and the like at the time of imaging. Using the dedicated imaging device having the above-described configuration, for example, an image and position information of 20 seconds before the arrival of the alarm target object and 10 seconds after the passage are automatically recorded, or passed from 1 km before the arrival of the alarm target object. It is possible to automatically record a video of 500 m later and position information, and acquire video data of live-action moving images respectively corresponding to alarm target objects nationwide.

(5) Preferably, the control means may be configured to synchronize the reproduction speed of the live-action moving image with the current vehicle speed based on vehicle speed information.

  According to the above configuration, by synchronizing the playback speed of the live-action video with the speed of the vehicle, it is possible to maintain a certain correspondence between the actual forward scenery and the live-action video according to the speed of the vehicle at the time of alarm It becomes. As a result, it is possible to display a live-action moving image at a playback speed corresponding to the speed of the vehicle at the time of alarm and a change in the speed of the vehicle, and it is possible to always provide an appropriate alarm.

(6) Preferably, the live-action moving image may include a landscape image that does not include the alarm object captured at a point before the alarm object passes.

  According to the above-described configuration, even when an approaching state in which the alarm object is not yet visible, for example, when a live-action video is displayed 1 km before and 500 m before the alarm target, Therefore, it is possible to easily understand the situation in which the vehicle is actually approaching the alarm object by watching a live-action moving image that does not include the alarm object.

(7) Preferably, the live-action moving image may be a series of images obtained by capturing a landscape from before the alarm object passes through to after the alarm object passes.

  According to the above configuration, the user can be notified of a series of live-action moving pictures from the start to the cancellation of the alarm. Here, since all of the alarms in the conventional radar detector described above are still images, only the still image before the passage of the alarm object is displayed, and the still image after the passage of the alarm object is displayed. There was no. For this reason, the alarm release timing was unclear. On the other hand, in the system of the present invention having the above-described configuration, the release of the alarm can be intuitively notified to the user by continuously displaying the video until after the alarm object passes.

(8) Preferably, the control unit displays a map on the display unit, and displays the live-action moving image on the map when the vehicle approaches the alarm target object up to a predetermined distance. It is good to make it.

  According to the above configuration, in a system such as a radar detector or a car navigation system, the position of the alarm target or the position of the vehicle is displayed on a map on the screen, and a live-action video alarm is displayed over the map. Is possible. Thereby, it is possible to objectively grasp the approach state between the vehicle and the alarm target object with the icon on the map while confirming the actual alarm target object with the live-action moving image.

(9) Preferably, the control unit may be configured to change a display area of the live-action moving image displayed on the map according to a distance from a vehicle to the alarm target.

According to the said structure, the approach state of a vehicle and an alarm target object can be alert | reported to a user with the display area of the live-action moving image displayed on a map. For example, when the vehicle and the alarm object are close to a predetermined distance, the live-action moving image is displayed with the smallest display area, and then the display area of the live-action moving image is increased as the vehicle and the alarm object are approached.
As a result, the approaching state between the vehicle and the alarm target can be relatively notified by the size of the live-action video, and the display area of the live-action video increases as the vehicle approaches the alarm target. It is easy to identify the alarm target inside. In addition, the display area of the live-action moving image increases as the vehicle approaches the alarm target, and a lot of information can be added to the live-action moving image.

(10) Preferably, an instruction display for visually specifying the alarm object included in the live-action moving image is added to the live-action moving image.

  According to the above configuration, it is possible to easily identify an alarm object included in the front scene of the live-action moving image by the instruction display. The front scene of the live-action video includes structures such as roads, other vehicles, buildings, signs, street lamps, etc., and it is difficult to specify an alarm object such as a speed measuring device from such a front scene. The faster the vehicle speed, the more difficult it is to identify the alarm object in the live-action video. Therefore, by adding an instruction display in the live-action moving image, the user can identify the alarm object in the live-action moving image at a glance.

Here, the above-mentioned “indication display” includes a wide range of indications indicating an alarm target object in a live-action video, for example, an arrow indicating the alarm target object in the live-action video, a balloon including information on the alarm target object, It includes a wide range of displays such as coloring on the entire alarm object and lines tracing the outline of the alarm object.
Such an instruction display may be configured to be embedded in a video of a live-action video, for example, but may be configured to be drawn in front of the video. For example, information such as the coordinate position in the screen of the alarm target in the live-action video, the size of the indication display, and the direction of the indication display are recorded for each predetermined frame, and the video of the live-action video is based on these information An instruction display may be displayed on the front of the screen.

(11) Preferably, the configuration may be such that at least one of the position and the size of the indication display is changed following the alarm target included in the live-action moving image.

  According to the above configuration, the alarm object in the live-action video whose position and size change as the vehicle approaches the alarm object can be accurately pointed by the dynamic instruction display. It is possible to more easily identify the alarm object in the video. For example, at the start of an alarm when the distance from the vehicle to the alarm object is long, the alarm object that is projected small in the live-action video is indicated by a small arrow, and the alarm object is indicated by a large arrow as the vehicle approaches the alarm object. To point.

  In addition, since such dynamic instruction display performs an artificial operation according to the program in the live-action video, it is particularly noticeable even in the live-action video that naturally changes as the vehicle travels, and the user's attention is instantly displayed. Can be attracted.

(12) Preferably, when the alarm object included in the live-action moving picture includes a plurality of components, the instruction display may be added to each component of the alarm object.

According to the above configuration, when the alarm target is a speed measurement device, it is possible to indicate an important component contributing to speed measurement with an instruction display, and it is possible to call a user's attention and promote safe driving. Become.
For example, when the speed measuring device is a radar type, loop coil type, H system, or LH system, the position of the camera of these speed measuring devices is indicated by an arrow. When the speed measuring device is a loop coil type, LH system, the loop coil embedded in the pavement is traced with a line. This makes it possible for the user to intuitively understand the purpose and function of the speed measurement device, and to provide a more effective alarm, and also to call the user's attention after seeing the alarm by the live-action moving image to promote safe driving.

(13) Preferably, the same alarm object is associated with video data of a plurality of the live-action moving images captured at different times, and the control unit is configured to detect any of the images captured at different times based on current time information. The video data may be selected, and the live-action moving image may be displayed on the display means.
(14) More preferably, the same alarm object is associated with at least two types of live-action moving images captured during the daytime and at night, and the control means is configured to perform daytime or nighttime based on current time information. The video data may be selected to display the live-action moving image on the display means.

  According to the above-described configuration, the timing for alarming with a live-action video is associated with the shooting time of the real-action video displayed on the display unit, for example, the environmental conditions of the video of the live-action video and the actual forward scenery are matched. Or it can be approximated. Here, as the “different time” in the present invention, when the vehicle travels in the range displayed in the live-action moving image, the user feels that the forward scenery at the time of actual driving and the displayed actual vehicle moving image are different. Select “Time”.

  For example, a live-action video may be provided for each period having a certain range with little change in scenery, such as spring, summer, autumn, winter, month, day, hour, morning, noon, evening, and evening. According to such a speed measuring device of the present invention, for example, during the day when the vehicle is in a predetermined approaching state with the alarm target, the day is a live-action video, the evening is a real-time video, the night Then, it becomes possible to display a live-action moving image at night. However, the present invention is not limited to the case where the environmental conditions of the video of the live-action video and the actual front landscape are matched, for example, even when the live-action video of daytime with good visibility is displayed at night when the visibility is poor Alternatively, from the same viewpoint, a summer live-action video may be displayed in the snowy winter.

(15) Preferably, the video data of the photographed image captured at night is captured at night using night vision.

If the area around the alarm object is a dark place with few street lamps, the image of the alarm object itself and its surroundings cannot be captured in a live-action movie even if a normal camera is used to capture a night image. Therefore, as in the above configuration, if a night video is captured using night vision, the alarm object itself and the surrounding situation can be included in a live-action video so as to be visible.
As a result, while matching the environmental conditions between the live-action video and the actual front landscape, the night vision video of the live-action video can be viewed even in the dark place at night, even if the actual alarm object in the front landscape is difficult to see. It is possible to specify the actual position and range of the alarm object with reference.

(16) In order to achieve the above object, the program of the present invention is configured to cause a portable terminal to function as any of the above-described systems of the present invention.

  According to the program of the present invention, for example, it is downloaded to a mobile terminal such as a mobile phone, a smart phone, or a mobile game machine, and a computer mounted on the mobile terminal executes the control process of the control means described above, and the vehicle warns. When a predetermined approach state with the object is reached, a live-action moving image can be displayed on the display means of the portable terminal to function as the above-described system of the present invention. The image data of the live-action moving image may be stored in, for example, a storage unit built in the mobile terminal, or stored in a server on the Internet.

(17) In order to achieve the above object, an imaging apparatus of the present invention is an imaging apparatus for acquiring video data of a live-action moving image used in any one of the systems (1) to (15) described above. Storage means for storing the position information of the alarm object already installed, position information acquisition means for acquiring the position information of the vehicle, and imaging means capable of capturing a moving image of the scenery in front of the traveling vehicle , Based on the position information of the vehicle and the position information of the alarm object, when it is determined that the vehicle has reached a predetermined approach state to the alarm object, the imaging means starts moving image capturing, An image pickup control unit that causes the image pickup unit to finish moving image shooting when it is determined that the vehicle has passed the alarm target is provided.

(18) Preferably, a radar detector including the position information acquisition unit and the storage unit is combined with a drive recorder including the imaging unit, and the imaging control unit performs imaging start timing and imaging end timing of the drive recorder. It is good to make the structure which controls.

And a program for causing a computer to realize the function to be performed.

(20) In order to achieve the above object, an imaging method of the present invention is an imaging method for acquiring video data of a live-action moving image used in any one of the systems (1) to (15) described above. The position information of the alarm object already installed is stored in the storage means, the position information acquisition means acquires the position information of the vehicle, and the imaging control means detects the position information of the vehicle and the position of the alarm object. Based on the information, the imaging means capable of capturing a moving image of the scenery in front of the traveling vehicle is controlled, and the imaging control means determines that the vehicle is in a predetermined approach state to the alarm object. In some cases, the imaging means starts moving image imaging, and when it is determined that the vehicle has passed the alarm target, the imaging means ends the moving image imaging.

  Hereinafter, the present invention will be described in more detail with reference to embodiments shown in the drawings. Note that the present invention is not limited thereby.

[First Embodiment of System]
1 and 2 show the configuration of a radar detector according to the first embodiment suitable as a system of the present invention. The radar detector is usually mounted on the dashboard. This radar detector is usually fixed by sticking the bottom surface of the plate 33b of the pedestal 33 on the dashboard. A ball joint receiving portion 33a is provided on the upper portion of the pedestal 33, and the ball portion provided at the lower end portion of the column portion 31 extending downward from the bottom surface of the case body 1 is inserted into the ball joint receiving portion 33a, and the ball portion is inserted. It can be held at an arbitrary angle and posture within the movable range.

  The pedestal 33 is provided with a spherical concave portion at a predetermined position on the upper surface thereof, and the pedestal 33 is made of a material that can be elastically deformed such as rubber and has an appropriate friction coefficient. The outer diameter of the ball portion and the inner diameter of the recess are set to be approximately equal. As a result, in a state where the ball portion has entered the recess, the outer shape of the ball portion and the inner shape of the recess substantially coincide, and the ball portion can rotate and move in any direction along the spherical surface. And while making both diameters substantially correspond and giving an appropriate friction coefficient to the inner shape of the recess, the ball part can be held at an arbitrary angle and posture.

  Furthermore, since the pedestal 33 can be elastically deformed, if the case body 1 is urged upward in the state shown in FIG. 1B while holding the pedestal 33, the diameter of the opening of the concave portion increases and the ball The part can be detached from the recess. On the other hand, when the pedestal 33 and the ball part are separated, if the ball part is pressed against the opening of the recess and urged to be pushed toward the pedestal 33 in that state, the opening is caused by elastic deformation of the recess. The part once expands and the ball part is accommodated in the recess.

  Thereafter, the shape of the recess is restored to the original by the elastic restoring force of the pedestal 33, and the ball portion is prevented from being easily detached from the recess. Further, one surface of an adhesive member such as an adhesive sheet, a double-sided adhesive tape, or a hook-and-loop fastener is attached to the bottom surface of the pedestal 33, and the other surface of the adhesive member is attached to a predetermined position in the vehicle interior such as a dashboard. Thereby, the base 33 is fixed to the predetermined position in the vehicle interior.

  As shown in FIGS. 1A and 1B, the radar detector has a solar panel 2 and a switch unit 3 disposed on the upper surface of the case body 1 and is disposed on the front side of the case body 1 (frontward of the vehicle). The microwave receiver 4 for detecting the microwave in the frequency band emitted from the speed measuring device is disposed inside the side (the windshield side). On the other hand, a display unit 5, an alarm lamp 6, an infrared communication device 7, and a remote control receiver 16 are arranged on the rear side of the case body 1 (the side arranged on the rear side of the vehicle (user side (driver side)).

  A GPS receiver 8 is disposed inside the upper surface of the case body 1. Further, the adapter jack 9 is disposed on one side surface of the case body 1, and the power switch 10 and the DC jack 21 are disposed on the other side surface. A battery (not shown) is provided inside the bottom surface of the case body, and the battery is charged with power supplied from the solar panel 2 and the DC jack 21 to supply power to each part. A speaker 20 is also built in the case body 1.

  In the present embodiment, the display unit 5 is a 2.4 inch small color dot matrix liquid crystal display having a backlight, and the rear side of the case body 1 (the side disposed on the rear side of the vehicle (user side (driver side)) The height H on the rear side of the case body 1 on which the display unit 5 is mounted is larger than the height H0 of the other parts.

  As shown in FIG. 2, the infrared communication device 7 transmits and receives data to and from a communication device incorporating an infrared communication device such as a mobile phone 12. The adapter jack 9 is a terminal for connecting the memory card reader 13. By connecting the memory card reader 13 to the adapter jack 9, the data stored in the memory card 14 attached to the memory card reader 13 can be taken into the interior, or the scenery of the process of approaching the position information and the alarm target can be viewed. The contents of the memory 19 of the database 19 or the control unit 18 storing the video data of the captured live-action moving image can be written to the memory card 14.

  Specifically, when the data stored in the memory card 14 includes update information such as information on a new alarm target (position information including longitude and latitude, type information, etc.), the update information is sent to the control unit 18. Is stored (downloaded) in the database 19 built in the radar detector, and the data in the database 19 is updated. The function of the memory card reader 13 may be configured to be built in the main body case 1.

  The database 19 is a nonvolatile memory (for example, EEPROM) in the microcomputer of the control unit 18 or externally attached to the microcomputer. Information relating to a certain alarm object is registered in the database 19 at the time of shipment, and data and the like regarding the alarm object added thereafter can be updated as described above. Data update can also be performed via the infrared communication device 7. The DC jack 21 is for connecting a cigar plug cord (not shown), and is connected to a cigar socket of the vehicle via the cigar plug cord so that power can be supplied.

  The wireless receiver 15 receives incoming radio waves having a predetermined frequency. The remote controller receiver 16 performs data communication with a remote controller (portable device: slave device) 17 by infrared rays and performs various settings for the apparatus. The switch unit 3 is also connected to the control unit 18 (not shown) so that the same setting as the remote controller 17 can be performed. The remote controller 17 includes a standby switch button, a setting button, a selection button, a cancel button, a determination button, a reset button, and up / down / left / right cross buttons.

  In addition, the radar detector of the present embodiment has an OBD-II (II is the Roman numeral “2” mounted on the vehicle as shown in FIG. 2, and “OBD-II” is hereinafter referred to as “OBD2”. ) A connection cable 22 to be connected to the connector is provided, and a connector terminal 23 that can be detachably attached to the OBD2 connector of the vehicle is attached to the tip of the connection cable 22. The OBD2 connector is also referred to as a failure diagnosis connector, and is connected to the ECU of the vehicle to output various vehicle information.

  Furthermore, the other end of the connection cable 22 is provided with a connector terminal 25 for connection to a socket port 24 provided on the side surface of the case body 1 of the radar detector. The connection cable 22 is also connected to the radar detector. It is designed to be removable. Of course, the connection cable 22 may be directly connected to the radar detector.
