Description

[0001] The present invention relates to a system and a black box for omnidirectional imaging,

The present invention relates to an imaging system for omnidirectional imaging that reflects light incident from a peripheral 360 ° direction and guides the light in a downward direction to image the same, and a black box for omni-directional imaging including the system.

The black box, originally developed for aircraft, is a device that records the flight status of the aircraft, such as altitude, route, speed, and engine conditions, and the contents of communication with the controller. It helps to pinpoint the accident situation of an aircraft. In recent years, black boxes have also been introduced in automobiles, providing information necessary for understanding the state of the accident by recording driving information such as images and vehicle speeds when the vehicle is in operation or when the vehicle is stopped.

However, at present, a black box for a car has a limited imaging angle of a camera, and a plurality of black boxes are required so that the front, rear, left and right rooms of a car are respectively photographed in order to record images in all directions around the car. Therefore, it is very costly to install a black box system, and it is also difficult to secure a space for installing a plurality of black boxes and an installation space. Also, the power consumed to operate a plurality of black boxes is large, so that discharge of an automobile battery may be promoted.

On the other hand, in the case of a moving means that is smaller than a car such as a motor cycle, a bicycle, a wheel board, and the like that are faster than the walking speed, and a speedy lap forward such as a ski or a snowboard, There is a problem that the black box is required for understanding the accident situation, but the installation place and the installation space of the installable black box can not be ensured while minimizing inconvenience of the user.

Meanwhile, a terminal of a USB memory may be inserted into the USB socket 126.

In addition, a WIFI module 128 may be mounted on the main circuit board 120 as another example of communication means. The WIFI module 128 may transmit the image data to a device outside the main body 80 in a wireless communication manner. An SD memory card slot 98 opened to attach and detach the SD memory card 125 to and from the SD memory card socket 124 from the outside of the main body 80, A USB slot 99 is opened to attach and detach a USB terminal to the USB socket 126.

The outer wall of the battery holder 100 is provided with a power button 118 for supplying electric energy to the main circuit board 120 and the image sensor 86 or for interrupting the supply of electric energy. A contact switch tact switch 122 is mounted on one side of the main circuit board 120 to press or press the power button 118 when the power button 118 is pressed. When the power button 118 is pressed in a state in which the omnidirectional imaging system 10 is not operated, the contact switch 122 is pressed to connect the power supply circuit and the main circuit board 120 and the image sensor 86, So that the image system 10 operates.

However, when the power button 118 is pressed again, the contact switch 122 is pressed again to cut off the connected power supply circuit, and the power supply to the main circuit board 120 and the image sensor 86 is cut off The operation of the video system 10 is turned off. The electric energy supplied to the main circuit board 120 and the image sensor 86 may be supplied from the battery 116 built in the main body 80 or from outside the main body 80.

The battery 116 supplies the stored electrical energy to the image sensor 86 and the main circuit board 120. The battery 116 may be a rechargeable secondary battery. A cushion pad 114 is provided on the side of the disk-shaped main body base 110. When the main body base 110 is coupled to the battery holder 100 so that the lower portion of the battery holder 100 is closed while the battery 116 is inserted into the battery bracket 101, And the upper surface of the battery 116 is in close contact with the battery bracket 101. [ Thus, the battery 116 is fixed in the battery holder 100 so as not to vibrate.

A locking unit including a hook 112 provided on the main body base 110 and a hook receiver 106 provided on the battery holder 100 to be interfered with the hook 112 The main body base 110 is detachably coupled to the battery holder 100. 5 and 6, the locking unit may include a hook provided in the battery holder 100 and a hook receiver provided in the main body base 110. [ On the other hand, the battery holder 100 and the main body base 110 may be coupled to each other by bolts (not shown), not by a locking unit.

Referring to Fig. 7, the omniazimetic imaging system 10 described with reference to Figs. 1 to 6 can be fixedly mounted on a helmet 3 for a motorcycle driver. In this case, the omnidirectional image-capturing system 10 may be used as a black box for identifying the cause of the accident occurring during the motorcycle operation, or may be used as a black box And can be used as a photographing device for photographing an image. The imaging system 10 for omnidirectional imaging may be attached to the upper surface of the helmet 3 by a coupling means such as an adhesive tape, a cord, a double-sided tape or a bolt or may be integrally formed with the helmet 3 .

7 is a view showing an example of a black box provided with the imaging system for omnidirectional imaging 10. In addition to this, a helmet for a bicycle driver, a skier helmet, a snowboarder helmet). In addition, the omnidirectional imaging system 10 may be fixedly attached to the roof of the vehicle, or the omni-directional imaging system 10 may be fixedly attached to the motorcycle or the bicycle body, not the helmet.

The imaging system 10 for omnidirectional image capturing described above can capture an object located at a height equal to or lower than the object itself in the 360 占 direction. Particularly, since the lens assembly 11 is disposed at a higher position than the main body 80, the main body 80 is installed on the helmet, the top of the wall, the top of the pole, or the roof of the vehicle, (11) can be fixedly mounted to pick up the surroundings. In this way, it is possible to install it in various places through the installation method to perform surveillance and object shooting.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
