[0002]

2. Description of the Related Art A conventional vehicle drive recorder records vehicle sensor signals indicating vehicle running conditions such as vehicle speed, acceleration, brake pressure, steering wheel steering angle before and after an accident, and analyzes the running condition of the vehicle. It is equipped with a camera that captures the surrounding environment, and the captured image of the vehicle running is continuously recorded in the recording section of the ring buffer structure, updating the oldest image in sequence, and an accident occurs when a shock detection sensor signal is received.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a configuration diagram of a vehicle drive recorder according to the first embodiment of the present invention. As shown in FIG. 1, a vehicle drive recorder according to a first embodiment of the present invention includes an image capturing unit 10 that captures an image of a vehicle surrounding environment, and an image processing unit 11 that detects a specific target from the captured image and performs image processing. , A memory 12 in which information used for detecting a specific object is stored, a drive unit 13 that changes the image capturing direction of the image capturing unit 10, a control unit 14 that controls the stop of the recording operation and storage of captured images, when an accident occurs, etc. An impact detection sensor 15 that detects the magnitude of the impact that the vehicle receives, a vehicle sensor 16 that detects information indicating the vehicle running state such as vehicle speed, acceleration, and brake pressure, a recording unit 17 that records the captured image and sensor information while updating it. The recording storage unit 18 stores the recorded captured image and sensor information.

In FIG. 1, the image pickup section 10 picks up an image of the environment in front of the vehicle, and the image processing section 11 carries out a predetermined process for detecting a specific object (a traffic signal in this embodiment) from the image picked up by the image pickup section 10. I do. The memory 12 stores information used for detecting a specific target in the image processing unit 11. The drive unit 13 is a mechanism for changing the image capturing direction of the image capturing unit 10, and is controlled based on the specific object detection result of the image processing unit 11.

The vehicle sensor 16 detects information indicating a vehicle traveling state such as vehicle speed, acceleration, and brake pressure.

The recording unit 17 is a memory having a ring buffer structure, and constantly records the imaged image of the imaging unit 10 and the sensor information of the vehicle sensor 16 while sequentially updating the oldest information. Then, when the impact detection sensor 15 detects an impact of a predetermined value or more, the control unit 14 stops the recording operation to the recording unit 17, and controls the control unit 14 to acquire the captured image and the sensor information recorded in the recording unit 17. It is transferred to the recording storage unit 18 via the.

Next, FIG. 2 shows an explanatory view showing the change of the image pickup direction of the image pickup unit 10 in the first embodiment of the present invention.
As shown in FIG. 2, the vehicle 25a approaches the intersection and the vehicle 2
At the position of 5b, in the imaging range 27a of the imaging unit 10 set to the initial value indicated by the dotted line, it becomes impossible to record the lighting state of the traffic light 26, which is useful information for cause analysis when an accident occurs. Therefore, by changing the image pickup direction of the image pickup unit 10 by the drive unit 13 to the upper side indicated by the solid line and setting the range as the image pickup range 27b, the vehicle is turned on by the traffic light 26.
Until the traffic light 26 detected by the image processing unit 11 passes through
Track and record the image.

When the image is tracked, the detected traffic signal 26 is set so as to be located in a predetermined area above the recorded image in order to prevent sunlight from entering due to the change of the image pickup direction. By setting the traffic signal 26 so as to be located in a predetermined area above the recorded image, it is not necessary to change the image capturing direction of the image capturing unit 10 upward more than necessary, so that it is difficult to record the traffic signal due to the incidence of sunlight. It can be resolved.

Next, FIG. 3 shows a flow chart for explaining the processing in the first embodiment of the present invention. First, the imaging direction of the imaging unit 10 is set to the initial angle, and recording of the vehicle surrounding environment is started (step 30). Then, the traffic signal 26 is detected from the recorded image (step 31). At that time, the traffic light 26 is detected by, for example, pattern matching processing with the feature amount of the traffic light 26 stored in the image memory 12, or extracting the lighting state of the traffic light 26 as an area having a brightness difference with a peripheral pixel of a predetermined value or more. It can be realized.

After detecting the traffic light 26 in step 31, the imaging direction of the imaging unit 10 is changed so that the detected traffic light 26 is positioned within a predetermined area 40 as shown in FIG. 4A. Control the imaging direction (step 3)
2). The image tracking is performed by the traffic light 26 as the vehicle progresses.
Moves toward the upper end of the image, so that it can be simplified by narrowing down the search near the upper end in advance.

Further, as shown in FIG. 4B, as the vehicle approaches the traffic light 26, the characteristic amount of the traffic light 26 may change and tracking may become difficult. For example, a plurality of characteristics corresponding to the above changes By storing the amount in the memory 12, selecting the feature amount that can be subjected to the pattern matching processing, and tracking the image, it is possible to prevent non-detection.

When the vehicle passes the traffic light 26, the traffic light cannot be detected (step 33).
The imaging direction of is returned to the initial value (step 34), and the process ends. In the above process, when the control unit 13 receives the signal that the impact detection sensor 15 has received the impact detection signal, the recording of the recording unit 17 is stopped and the recorded image is recorded and saved via the control unit 14. It is transferred to the section 18 and saved.

As described above, the traffic light is detected from the captured image of the environment surrounding the vehicle, the traffic light is image-tracked, and the imaging direction of the imaging unit 10 is drive-controlled so that the traffic light is located within a predetermined area of the image. As a result, the traffic signal can be stably recorded even when the vehicle approaches the intersection, and the lighting state of the traffic signal when the vehicle approaches the intersection can be analyzed.

In the unlikely event of an accident at an intersection, the running condition and the surroundings of the vehicle can be analyzed from the vehicle sensor information and the picked-up image recorded in the record storage unit 18.
Further, by setting the image capturing direction of the image capturing unit so that the traffic light is located above the captured image, the upward angle of the image capturing unit can be suppressed as much as possible, and sunlight can be prevented from entering as backlight. . Further, under the condition that visibility of the surroundings of the vehicle is low and it is difficult to observe the behavior of the surrounding vehicles from the recorded image, such as during nighttime driving, the above detection information including the lighting state of the traffic signal can be a powerful clue for accident cause analysis.
