Description

A vehicular blackbox for acquisition and recording images of blind spots using a reflector}

The present invention relates to a vehicle black box device capable of acquiring and storing a blind spot image using a spherical reflector. Specifically, by using a spherical reflector in a vehicle black box equipped with only one front camera, the rear and side reflection images are acquired, and the reflected images are processed and integrated with the front image, so that the front and rear images are simultaneously displayed to the user. The present invention relates to a vehicle black box for providing an image of the vehicle, a reflector module and an image receiver applicable to a separate photographing apparatus.

The black box was originally equipped on the aircraft to investigate the cause of the accident, but recently, the vehicle black box has been continuously installed to accurately identify the accident situation of the vehicle, thanks to the advancement of technology and the spread of digital devices. It is increasing. In the case of vehicle black boxes, the amount of stored data is gradually increasing due to high-definition recording of images to provide accurate information in an emergency situation. Since recording is essential, recording of rear and side images is also gradually increasing.

In a video recording / storage / monitoring system that records, stores, and monitors images such as a car black box, cameras, which are photographing devices, have a limited angle of view. For example, the vehicle image capturing / storage device mainly photographs the front situation while the vehicle is driving, and installs the image capturing / storage device in the front direction near the front vehicle glass. In this case, the situation such as rear or side cannot be recorded / saved.If you want to record / save not only the front but also the rear and side situation even while driving or stopping, you need to install several video recording / storage devices. Two photographing apparatuses are provided at the front and the rear, and four or more photographing apparatuses are installed at both the front, rear, and side surfaces. However, in the case of multiple photographing devices, the efficiency of the storage medium decreases and it becomes difficult to integrate and record each image.

Therefore, in the vehicle black box, it is advantageous to record and record a wide-angle image. However, when a wide angle of view such as a fisheye lens is included in one screen, the resolution of the peripheral portion is optically deteriorated and the captured image of the peripheral portion is distorted. There is a possibility of loss. In addition, since a high distortion compensation algorithm increases the overhead of a processor such as a CPU (central processing unit) to compensate for distortion of a wide-angle shot image, even if distortion is corrected through distortion compensation, image processing is performed. Due to this limitation, resolution and image quality deteriorate inevitably.

As a related art in this regard, Patent Document 1 proposed in the following prior art document discloses a vehicle black box for photographing and recording a driving situation and an accident situation of a vehicle by a camera. The camera of the vehicle black box is provided with a front camera and a side camera at the front and rear sides of the main body to simultaneously photograph the front and both sides of the vehicle, and the side camera is installed at the rear side of the main body to perform the shooting. A prism lens for collecting both sides of the vehicle is installed.

Patent document 2 discloses the camera module which uses the lens using the principle of total reflection prism. A camera module having a total reflection prism means around the side of the wafer lens to receive and reflect the light from the side to collect the light from the front and side and transmit the light to the image sensor so that the photographing angle of the image is 200 degrees or more. Is starting.

The vehicle black box of Patent Document 1 has an effect of lowering the manufacturing cost according to the reduction of the number of cameras, and the wide-angle camera module of Patent Document 2 has an effect of partially reducing the blind spots. However, the vehicle black box of Patent Document 1 has a disadvantage of using at least two cameras, and the camera module of Patent Document 2 cannot overcome the disadvantage of wide-angle imaging as described above.

In order to overcome the problems of the prior art, the present invention provides a vehicle black box using one imaging device and a spherical reflector. The present invention can shoot and store the reflection image of the spherical reflector while using a single photographing device, and can simultaneously record and store the image of the rear and / or side as well as the front image, it can solve the problems of the prior art described above have.

Therefore, the problem to be achieved by the present invention is that the recording area of the vehicle black box with one sensor having a sensor and a lens is limited by the mounting position and angle of view, even if a wide-angle imaging device is used, The area that can be captured by the camera is mostly limited to the front area even when image processing such as digital post-processing is performed. For the distortion compensation due to the wide angle, the deterioration of recording quality is inevitable. In order to compensate for this problem, a spherical reflector is additionally installed in front of the photographing apparatus, and the rear and side reflection images are integrated into the photographed images at the front to simultaneously record and store the blind spot images of the rear and / or side with one photographing apparatus. Since the recording is integrated in the rear, and the reversed image is reflected in the rear, it is intended to provide an apparatus for correcting and recording by enlarging and inverting a specific region through image processing.

In order to solve the above technical problem, the present invention includes a reflector module mounted on a camera module to provide a rear and / or side reflection image, and a camera module for photographing the front image and the rear and side reflection images. It provides a vehicle black box including a video receiving unit, a control unit for controlling the processing of the image data photographed by the image receiving unit, a storage unit for storing the image data photographed by the image receiving unit.

In addition, the present invention is a reflector module mounted on the front of the photographing device to provide a rear and / or side reflected image, the reflector module is a transparent lens portion made of a transparent member for front photographing, adjacent to the transparent lens portion A reflector for providing a reflection image of the rear and / or side, the transparent lens unit and the reflector are installed, a ring member mounted to the front of the photographing apparatus, and for supporting and mounting the ring member to the camera module. It provides a reflector module including a support member.

In addition, the present invention is an image receiving unit included in the device for image capture and storage, the image receiving unit is mounted on the camera module reflector module for providing a reflection image of the rear and / or side, the front image and the rear and side And a camera module for capturing a reflected image of the camera module, wherein the camera module includes a camera lens and a sensor, and the sensor includes a front sensing unit configured to sense a front image, and a reflector configured to sense the reflected image provided by the reflector. Provided is an image receiving unit including a sensing unit.

According to the present invention, by using one photographing apparatus having a sensor and a lens and a spherical reflector, the present invention has the effect of recording like an image recorded by two or more photographing apparatuses while using one photographing apparatus. That is, the angle of view of the photographing apparatus is substantially enlarged, and the image of the rear and / or the side as well as the image of the front side can be photographed and stored, so that the blind spot is reduced or disappeared.

In addition, according to the present invention, since two images can be integrated and recorded in one image, the capacity of the storage device can be efficiently used, and by adjusting the curvature and the position direction of the mounted spherical reflector, This has the effect of enabling recording of the ROI.

In addition, in the rear image photographed by the spherical reflector, the image in which the left and right are reversed is reflected, but the rear image is separately post-processed and mirrored to record the rear image part separately through the internal image processing. It has the effect of providing the same image as the actual viewing image.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a view for explaining the principle of the vehicle black box according to the present invention, Figure 2 is a view for explaining the internal structure of the vehicle black box according to the present invention. 1 and 2, the present invention mounts a reflector in front of one imaging device to capture and store the rear and / or side reflection image together with the front image. The camera, which is a photographing apparatus, includes a lens and a sensor. As illustrated in FIG. 2, the sensor includes a front sensing unit 250 that senses an image of the front side, and a reflector sensing unit 260 that senses an image of the rear and / or side surfaces. It includes. Although the position where the reflector is mounted on the photographing apparatus may be various positions, it is determined that the lower end is advantageous as shown in FIG. 2. The reason for this is that the lower part of the image obtained from a single photographing device in a vehicle black box does not have important information such as the image of the vehicle bonnet. By overlapping the lower end of the front image, the enemy records the situation of the rear and / or the side simultaneously in one recorded image. Place the shooting device in the desired direction so that the most important video information is recorded, and reflector to position the image reflected through the reflector on the shooting screen of the smallest amount of information on the shooting screen (for vehicle use, etc.) If you install it, you can shoot and save a much wider screen than the camera has with one shooting / storage system. At this time, the reflector should be installed so as not to cover the screen where the main information is taken.

The reflector mounted in order to enlarge the range of the image captured and stored may use a flat mirror or a prism lens, but a convex mirror-shaped spherical reflector can secure a wide angle of view. This allows you to shoot and save blind spots on your device. By adjusting and mounting the curvature and the position direction of the spherical reflector, it is possible to record a desired region (including a blind spot) of a region of interest, ie, rear and / or side, with one imaging apparatus. Spherical reflectors made of convex mirrors will be useful for widening the angle of view. Referring to FIG. 1, some specific areas of the entire screen of the photographed screen become areas through the spherical reflectors. Due to the characteristics of the convex mirror spherical mirror, the reflected image is reversed to the left and right, and a smaller image than the actual size is taken. It is processed and stored. By processing in this way, an image of a specific region of the entire screen by the reflector can also be obtained at the same magnification as the original front-photographed image, thereby securing the actual full screen from the user's point of view.
