  The present invention relates to a drive recorder that can capture and store a desired landscape while driving.

2. Description of the Related Art A drive recorder is known that can store images before and after an accident when a vehicle accident occurs and later confirm the situation of the accident. In recent years, there has been known an example in which a drive recorder can take a picture of a landscape during driving and save it. For example, Japanese Patent Application Laid-Open No. 2006-211415 proposes a vehicle peripheral video recording apparatus that records information on a driving state in synchronization with a landscape video shot during driving and allows a driver to easily view it later.
JP 2006-2111415 A

  However, in the above recording device, the image is discriminated based on the driving state information by the in-vehicle sensor or the image processing after the image data is acquired, and the landscape image intended by the user is not necessarily selected. It couldn't be recorded.

  An object of the present invention is to solve the above-mentioned problems and to provide a drive recorder that saves images before and after an accident and has a function of saving only a favorite landscape during driving.

  In the present invention, the drive recorder is configured as follows in order to solve the above problems.

1. A drive recorder according to the present invention includes an in-vehicle camera and a recording device. When an accident occurs in a vehicle, the drive recorder stores images before and after the accident that are captured by the in-vehicle camera in the recording device. An input means for inputting information of a desired landscape desired to be acquired, a traveling state of the own vehicle is obtained from a car navigation device installed in the vehicle, a landscape of a route through which the own vehicle passes is predicted, and the predicted landscape Determining whether a prediction means for calculating a horizontal distance and an altitude difference from the own vehicle, information on a predicted landscape predicted by the prediction means, and information on a desired landscape input to the input means match; and determining means for setting the location information of the prediction landscape and the desired information landscape matches as a main shooting location, the horizontal distance between the desired scene and the vehicle is, the desired scene and the vehicle Wherein when the whole image of the desired scene on the basis of the height difference is longer than the horizontal distance that is can be taken during, a, and actuating means for saving the image in which the vehicle camera is captured into the recording apparatus.

2. The drive according to 1, wherein the operation unit causes the recording device to store an image captured by the in-vehicle camera even when it is determined that the host vehicle is traveling in the required shooting location. Recorder.

3, said actuating means, said even if it is determined that the vehicle from a main shooting location at a predetermined distance before it reaches, wherein the image said vehicle camera has taken 1 was be stored in the recording device Drive recorder.

4. The actuating means calculates the length of the location corresponding to the required shooting location, and when the length of the required shooting location is determined to be greater than or equal to a predetermined length, the in- vehicle camera has taken the image. 4. The drive recorder according to 2 or 3, wherein video is stored in the recording device.

5, create dynamic means determines the elevation of the point at which the vehicle is traveling from mosquitoes over the navigation device, drive recorder was decided to operate the record device depending on the altitude.

6, create dynamic means determines the elevation of hope landscape that has been input to the input means from mosquitoes over the navigation device, and calculates the difference between the elevation of the point where the hope landscape of the altitude and the vehicle is traveling, target it and the drive recorder to operate the record apparatus in accordance with the height difference.

The drive recorder according to the present invention has the following effects.
Since the drive recorder saves the video before and after the accident in the recording device, the situation of the accident can be accurately verified as an original function. Further, during the drive, the recording device is operated based on the desired landscape information inputted in advance, and the video taken by the in-vehicle camera is stored in the recording device. Therefore, since the scenery desired by the user is selected and stored in the recording device, the user can appreciate the desired scenery by later taking out and reproducing the video with a recording medium or the like. In addition, since the video can be arbitrarily stored, it can be used for the purpose of storing the video of traveling on a circuit and the like for use in the next driving, for example.

  Furthermore, in addition to the intended use of the drive recorder, other uses are added, so that it is possible to increase the spread of drive recorders that are expected to be used for investigation of accident factors.

An embodiment of a drive recorder according to the present invention will be described with reference to the drawings.
FIG. 1 shows a schematic configuration of the drive recorder 10. The drive recorder 10 includes a camera 11, a control means 12, an input device 13 as an input means, a recording device 14, an acceleration / deceleration sensor 15 and the like as indicated by a dotted line.

  The drive recorder 10 is connected to a car navigation device (also referred to as a car navigation device) 20 using a GPS function and a speed sensor 21 that detects the traveling speed of the vehicle. The car navigation device 20 detects the current position of the host vehicle using the GPS function, and when the destination is input, calculates the route from the current location to the destination and displays a display device (not shown) installed in the vehicle. Z)) displays the route along with the current position.

  The camera 11 is a camera for a normal drive recorder that is installed in a vehicle (not shown) mainly in front of the shooting range, and the shot video is sent to the control means 12 as an electrical signal. It should be noted that a plurality of cameras 11 may be installed facing forward, and the camera 11 may be installed so as to photograph the side or rear of the vehicle, even if the camera to be photographed is switched.

  The input device 13 is a device that can input character information and numerical values such as a keyboard and a touch panel. The input device 13 is preferably installed in the drive recorder 10. However, the input device 13 is provided separately from the drive recorder 10 and connected to the drive recorder 10 each time information is input, in the remote control format, or other processing. Information may be input by the apparatus, the input information may be recorded on an external recording medium or the like, the external recording medium may be loaded into the drive recorder 10, and necessary information may be input to the drive recorder 10.

  When detecting the occurrence of an accident, the control means 12 stores the video before the accident in the recording device 14 and operates the camera 11 after the accident to store the video in the recording device 14. It has a function.

  The recording device 14 is preferably a solid recording medium, so-called solid memory, in terms of impact resistance, but is not limited thereto. Further, it may be a card type and can be removed from the main body, or may be fixed to the main body so as not to allow modification of the image. However, it is easy to read the recorded content or move the image to another medium.

  The drive recorder 10 has, as an original function of the drive recorder, determination means (not shown) for determining that an accident has occurred when values from the acceleration / deceleration sensor 15 and the speed sensor 21 exceed a threshold value, and determination means. The operation means (not shown) for saving the video based on the determination is provided. The camera 11 is always in a state of photographing, and when the photographed video information is sent to the recording device 14, it is recorded in the recording device 14 for a predetermined time and then sequentially deleted. When the judging means recognizes that an accident has occurred, the actuating means actuates the recording device 14 to store the image information recorded in the recording device 14 and also the image taken by the camera 11 after the accident is predetermined. Save time.

  Further, the control means 12 has a function of storing a desired landscape video. Next, a description will be given of the scenery video storage function of the control means 12. In addition to the original function of the drive recorder, the control means 12 includes, as shown in FIG. 2, a storage means 22 for storing inputted information, a prediction means 23 for predicting a landscape, a determination means 24, and a recording device. 14 and the like. A manual switch 26 is connected to the operating means 25.

  The storage unit 22 stores information input from the input device 13, for example, information on a desired landscape of the sea that is input when a sea view is desired. Further, other information may be stored. As a method of storing information, in addition to directly inputting character information, options previously input may be appropriately selected.

  The predicting means 23 predicts a landscape appearing on a road to be passed from the current position of the own vehicle detected by the car navigation device 20 and map information around the current position. For example, if a road passes between mountains, a mountain landscape will continue from one point to another, and if it is a route along the sea, a sea landscape will continue. Predict from map information. In addition, when the destination is input, the car navigation device 20 calculates a route from the current position to the destination, and sends the route and information around the route to the prediction unit 23. The scenery may be predicted from information around this route.

  The determination unit 24 compares the desired shooting information stored in the storage unit 22 with the predicted landscape predicted by the prediction unit 23, and matches the position or the road section that matches (hereinafter, it is also necessary. Determine the shooting location.)

  The actuating means 25 makes a determination based on the current position information of the own vehicle from the car navigation device 20 and the required shooting location determined by the determining means 24, and sends a signal to the recording device 14 that an image should be recorded. The recording device 14 is basically a recording device that stores the situation before and after the accident, and the recording method is not particularly limited.

  The recording device 14 may be provided separately from the recording device that stores the situation before and after the accident. The image stored in the recording device 14 may be a still image, or an audio signal may be stored together with the image signal. The audio signal may be collected using a microphone provided in the camera 11 or using a microphone (none of which is shown) provided at another location. Further, the direction of the scenery to be saved may be switched by switching the camera as appropriate.

  Next, the operation of the drive recorder 10 will be described using the flowchart of FIG.

  First, a desired landscape is input from the input device 13 of the drive recorder 10 before or during traveling (S-1). If the desired landscape is the sea, for example, information on the sea is input. In addition, the length of the road where the video should be stored, the time for saving, and the like are input as appropriate. Such information is stored in the storage means 22.

  When traveling is started, shooting is performed by the camera 11 (S-2). The photographed video is sent from the control means 12 to the recording device 14. The video information sent to the recording device 14 is erased as needed after recording for a predetermined time.

  Fig. 4 shows the terrain on which the vehicle is traveling. In this landform, the sea A is above (north), and there is a road C along the coastline B and a road D that hits the road C. The road D passes near the mountain E, and there is a road F toward the mountain E. The vehicle is now traveling toward the sea A from the position P1.

  The prediction means 23 obtains information from the car navigation device 20 that the current position of the vehicle is P1. In addition, information on the vicinity of the road on which the vehicle is traveling is received (S-3). As information, there is the sea A in the traveling direction of the vehicle, and the section m of the road C is along the coastline B. The prediction means 23 performs various predictions using such information, such as being able to photograph a seascape in the section m (S-4). The predicted landscape information is sent to the determination means 24.

  The determination unit 24 obtains information that the desired landscape is the sea from the storage unit 22 and obtains information on the predicted landscape from the prediction unit 23. Then, the two are compared, and based on the prediction that the seascape can be photographed in the section m, the section m is set as a place requiring photographing (S-5) as a place where both match. Information on the set required shooting location is sent to the operating means 25.

  The actuating means 25 determines whether or not the own vehicle is in the section m determined by the determining means 24 based on the current position information of the own vehicle sent from the car navigation device 20 (S-6). Return to S-3. On the other hand, if it is confirmed that the vehicle is traveling in the section m, a signal for causing the recording device 14 to save the image is sent out.

  When the recording device 14 receives the storage signal from the operating unit 25, the recording device 14 stores the video information captured by the camera 11 (S-7). Further, the actuating means 25 determines whether or not the vehicle has exited the section m, or whether or not the distance and time have exceeded the upper limit values from the start of shooting (S-8), and these must not exceed the upper limit values. For example, the image storage by the recording device 14 is continued, and if it is determined that the upper limit has been exceeded, a signal for stopping the image storage is sent to the recording device 14 to stop the storage (S-9).

  As a result, during the drive, a desired seascape, that is, an image when the own vehicle is traveling in the required shooting location in the section m shown in FIG. The landscape image stored in the recording device 14 is reproduced in the car, stored in an external recording medium such as a solid-state memory, taken out from the drive recorder 10, reproduced on a home reproducing device, etc., and photographed during driving You can enjoy and enjoy the scenery.

In the above example, the video is stored in the shooting location, but another example will be described next.
In this case, it is determined whether or not the desired landscape can be photographed even when the vehicle is actually traveling in the desired landscape. If it is determined that the photograph can be photographed, the video is stored. In other words, taking into account the elevation difference between the desired landscape and the vehicle and the distance to the desired landscape, predict whether you can see the sea, the ridgeline of the mountain, etc., and set the required shooting location based on such prediction .

  For example, in the terrain shown in FIG. 4, it is assumed that the vehicle is traveling toward the sea A from the point P2. The predicting means 23 obtains the altitude of P2 from the contour line information, and confirms that the host vehicle is traveling while descending toward the sea A. Thereby, when the vehicle approaches a predetermined distance to the sea A, it is determined that the sea A can be photographed. For example, an area where photography is possible is defined as section n. If it judges in this way, a picture will be preserved when the own vehicle is running in section n. Then, the landscape image of the sea A photographed from the mountain side can be saved.

  A case where a mountain is set as a desired landscape will be described as an example. In FIG. 4, it is assumed that the own vehicle is located at P <b> 3 and is traveling on the road F toward the mountain E toward the mountain E. In this case, the altitude difference h between the altitude of the mountain E and the altitude of the position of the own vehicle is calculated, and the altitude difference h and the horizontal distance d between the mountain E and the own vehicle are obtained. Then, an area q in which the horizontal distance d satisfies the expression 2h <d <5h is set as a shooting required place. h is a value that varies depending on the location.

  In this way, when the section q is set as a required shooting location, when the own vehicle approaches a position five times as high as the altitude difference h from the mountain E, image storage is started, and the own vehicle has an altitude difference h from the mountain E. When approaching the double position, the video storage is stopped. Therefore, the image of the mountain E can be saved from a distant view to a close view. Here, the reason why the altitude difference h is set to 5 times is that it is considered that the image of the mountain E cannot be obtained at a position farther than that. Then, it is because it is thought that the whole image of the mountain E cannot be seen, and this expression can be appropriately changed according to the altitude of the mountain, the surrounding situation, and the like.

  The desired scenery may be a scenery near the destination. In this case, the horizontal distance d between the position of the own vehicle and the destination is obtained, and when the own vehicle approaches a preset distance, image storage is started. The image storage is continued until, for example, the destination is reached. Alternatively, a plurality of distances to the destination may be set, and the video from the camera 11 may be stored for a predetermined time when the set point is reached. Then, the surrounding video image | photographed in the appropriate position between the destinations is preserve | saved.

  Further, the video may be stored by operating the switch 26. Then you can save the video at any point. For example, it is possible to save a video of running on a circuit and view the video later for use in the next run.

  Note that the storage is not limited to moving images, but may be still images. In addition, it is preferable that all video images are stored together with image information, position information, and the like detected by the car navigation device 20.

  Furthermore, according to the drive recorder of the present invention, the drive recorder that only stores the original accident situation can be used for other purposes, particularly for entertainment, and can be used to further promote the spread of the drive recorder.
