Description

Technical Field

[0001] The present invention relates to a rapid acceleration recording method using a black box and an apparatus for performing such a method. More particularly, the present invention relates to a rapid acceleration recording method using a black box for proving a rapid acceleration situation based on an image captured through the black box, and an apparatus for performing such a method.

Background Art

[0002] Recently, many casualties have occurred in rapid acceleration estimation accidents in the country, which has become a social issue and occurs continuously every year. Most drivers at the time of the accident stated that they stepped hard on the brake pedal. However, when actually inspecting the pedals of the accident vehicle, if parts such as the pedal pad and pedal arm of the accelerator pedal assembly are damaged, if the accelerator pedal is restricted by surrounding structures, or if the pattern of the driver's shoe sole is printed on the accelerator pedal pad or the pattern of the accelerator pedal pad is printed on the shoe sole, etc., there are many cases where it is confirmed that the accelerator pedal was operated instead of the brake pedal.

[0003] In order to confirm such rapid acceleration accidents, accurate evidence materials are required. Currently, black box products that can capture images of the pedals are being researched and sold. However, in the case of current products, it is difficult to prove the simultaneity between the driving situation video during driving and the pedal video for the pedals. Therefore, the current black box products for capturing images of rapid acceleration have low evidentiary ability, and research on a method to overcome the shortcomings of such current black box products is necessary.

Modes for Carrying Out the Invention

[0017] FIG. 1 is a conceptual diagram showing a black box according to an embodiment of the present invention.

[0018] In FIG. 1, a method for generating a pedal video and a front video and generating a hologram watermark for the pedal video and the front and rear videos is disclosed.

[0019] Referring to FIG. 1, the black box may include a pedal video generation unit 100, a front and rear video generation unit 110, a video combining unit 120, a hologram watermark generation unit 130, a final combined video generation unit 140, and a processor 150.

[0020] The pedal video generation unit 100 may be implemented to capture a user's pedaling video. The pedal video generation unit 100 can capture the use of the user's brake pedal and accelerator pedal and generate it as a pedal video.

[0021] The front and rear video generation unit 110 may be implemented to capture a front video and / or a rear video during driving. The front and rear video generation unit 110 can generate the front and rear videos as front and rear videos during operation with a front camera and / or a rear camera.

[0022] The video combining unit 120 may be implemented to combine the pedal video and the front and rear videos. The video combining unit 120 can match the temporal synchronization of the pedal video and the front and rear videos and combine the front and rear videos and the pedal video at a specific time to generate a combined video.

[0023] The hologram watermark generation unit 130 may be implemented to generate a hologram watermark. The hologram watermark can be attached to the combined video. The hologram watermark can randomly include a separate pattern such as a gradation.

[0024] The final combined video generation unit 140 may be implemented to generate a final combined video by combining the combined video and the hologram watermark.

[0025] The processor 150 may be implemented to control the operations of the pedal video generation unit 100, the front and rear video generation unit 110, the video combining unit 120, the hologram watermark generation unit 130, and the final combined video generation unit 140.

[0026] FIG. 2 is a conceptual diagram showing the operation of the watermark generation unit according to an embodiment of the present invention.

[0027] In FIG. 2, a hologram watermark added to the combined video is disclosed.

[0028] Referring to FIG. 2, the hologram watermark 200 can be positioned to overlap a part of each of the front and rear video 220 and the pedal video 210.

[0029] A combined video 230 including the front and rear video 220 and the pedal video 210 may be generated, and the first area in the combined video 230 may be assigned for the pedal video 210, and the second area may be assigned for the front and rear video 220. The hologram watermark 200 is positioned between the first area and the second area and can be utilized to prove that the pedal video 210 and the front and rear video 220 were generated at one point in time.

[0030] The hologram watermark 200 may be generated including a gradation, and the gradation may be randomly generated so that arbitrary changes are impossible. Alternatively, the angle, shading, etc. of the hologram watermark 200 may also be randomly determined during video recording.

[0031] Also, according to an embodiment of the present invention, information regarding the hash value generated based on the hologram watermark 200 may be included on the combined video 230. The information regarding the hash value may also be implemented to be located on the pedal video 210, which is the first area, and the front and rear video 220, which is the second area, on the combined video 230 including the front and rear video 220 and the pedal video 210.

[0032] Since the hologram watermark 200 and the hash value are input in image form, they cannot be arbitrarily changed. Also, when the pedal video 210 or the front and rear video 220 is changed, not only the hash value but also only the part of the hologram watermark 200 needs to be changed, so image distortion that can be confirmed with the naked eye will occur and traces of video distortion will remain.

[0033] FIG. 3 is a conceptual diagram showing the final combined video according to an embodiment of the present invention.

[0034] In FIG. 3, the final combined video is exemplarily disclosed.

[0035] Referring to FIG. 3, on the final combined video, the hologram watermark 300 can be embodied to be located on the pedal video which is the first area and the front and rear video which is the second area on the combined video. The hologram watermark 300 can be randomly generated in a size that does not interfere with the analysis of the original video and can be located on the combined video.

[0036] FIG. 4 is a conceptual diagram showing a method for generating a hologram watermark according to an embodiment of the present invention.

[0037] In FIG. 4, a method for generating a hologram watermark and positioning it on the front and rear video and the pedal video is disclosed.

[0038] Referring to FIG. 4, a method for generating a gradation pattern 400 for generating a hologram watermark is disclosed.

[0039] In the present invention, since the gradation pattern 400 of the hologram watermark is generated for the confirmation of the modulation of the front and rear images and the pedal image, it must be continuously positioned with respect to the front and rear images and the pedal image. Therefore, the gradation pattern 400 of the hologram watermark of the present invention can be generated so that the gradation pattern 400 can be connected and positioned on the front and rear images and the pedal image in consideration of the positions of the front and rear images and the pedal image during reproduction.

[0040] Therefore, the hologram watermark generation unit of the black box of the present invention randomly generates a gradation considering the positions of the front and rear images and the pedal image when generating the hologram watermark, but can generate the hologram watermark so that the gradation pattern 400 can be connected on the front and rear images and the pedal image.

[0041] Also, according to an embodiment of the present invention, the hologram watermark can be generated so as not to block important image areas in the front and rear images and the pedal image. For example, the position where pedaling is performed on the pedal image can be set as the first main image area 410, a specific first angle range area in front of the camera on the front and rear images can be set as the second main image area 420, and a specific second angle range area behind the camera can be set as the third main image area 430.

[0042] The hologram watermark generation unit can generate the hologram watermark so that the first main image area 410, the second main image area 420, and the third main image area 430 are not blocked.

[0043] The hologram watermark generation unit determines the hologram watermark position 440 through judgments on the first main image area 410, the second main image area 420, and the third main image area 430, and can position the hologram watermark at the hologram watermark position 440.

[0044] Also, according to an embodiment of the present invention, additional logic for generating the gradation pattern 400 may be used.

[0045] The gradation pattern of the hologram watermark may be generated by being divided based on the position of the reproduced video. When the video includes a front video, a rear video, and a pedal video, the hologram watermark can be located on the front video, the rear video, and the pedal video, and the gradation pattern of the hologram watermark can be generated to be continuous on the front video, the rear video, and the pedal video.

[0046] For generating the gradation pattern, the hologram watermark may be divided into a first sub - hologram watermark area corresponding to the front video, a second sub - hologram watermark area corresponding to the rear video, and a third sub - hologram watermark area corresponding to the pedal video.

[0047] According to an embodiment of the present invention, although the hologram watermark generation unit randomly generates the gradation pattern, the gradation pattern can be generated to be continuous on the first sub - hologram watermark area, the second sub - hologram watermark area, and the third sub - hologram watermark area.

[0048] Also, in particular, on the portion where the first sub - hologram watermark area corresponding to the front video is connected to the third sub - hologram watermark area corresponding to the pedal area, a gradation pattern with a higher weighting value may be generated. When the hologram watermark generation unit assigns a weighting value to the gradation pattern, it can generate the gradation pattern in a way that more gradation pattern numbers are allocated to strengthen the proof of simultaneity between the corresponding areas.

[0049] FIG. 5 is a conceptual diagram showing a method for determining the generation of a hologram watermark according to an embodiment of the present invention.

[0050] In FIG. 5, the setting of the generation option of the hologram watermark in the driving situation is disclosed.

[0051] Referring to FIG. 5, when the black box is operating, a hologram watermark can be generated, and the hologram watermark may be generated in a changed manner based on the driving record of the user.

[0052] The black box video can be classified into real-time recorded video 500 and non-real-time recorded video 510. The real-time recorded video 500 can be video captured and input on the black box in real time. The non-real-time recorded video 510 can be video that is not real-time video, and when a separate event (for example, impact) occurs, the video in time units is separately separated and stored in another storage location.

[0053] For the real-time recorded video 500, an initial hologram watermark can be generated at the start of the vehicle operation. In the case of the initial hologram watermark, it can be maintained until the end of the vehicle operation. Or, according to the setting, when the vehicle is stopped or the vehicle does not move for a certain period of time or more, a new hologram watermark can be generated and assigned to the video. When the hologram watermark changes during operation, the hash value of the new hologram watermark can be implemented to be generated based on the hash value of the previous hologram watermark. That is, by relating the hash value of the new hologram watermark and the hash value of the previous hologram watermark, it can be implemented so that the relationship between the previous hologram watermark and the subsequent hologram watermark can be confirmed.

[0054] Or, according to an embodiment of the present invention, after the previous hologram watermark and the new hologram watermark are maintained simultaneously for a certain period of time, only the new hologram watermark can be maintained.

[0055] The non-real-time recorded video 510 records the video in which an event has occurred among the already recorded videos, and can be classified into a first-option non-real-time recorded video 520 in which the hologram watermark used for the real-time recorded video is maintained, and a second-option non-real-time recorded video 530 to which a separate hologram watermark is assigned.

[0056] The first-option non-real-time recorded video 520 can be a recorded video in which the hologram watermark used for the real-time recorded video is maintained as it is.

[0057] The second-option non-real-time recorded video 530 can be a recorded video in which a new hologram watermark is generated and saved when the hologram watermark changes in the middle. When the hologram watermark changes in the middle on the video separated as the event-occurrence video, a new hologram watermark can be generated and included on the video to make it easier to confirm on the video. The hologram watermark added to the second-option non-real-time recorded video 530 can be a hologram watermark generated based on the hash values of a plurality of hologram watermarks included in the real-time recorded video.
