Description

 The present invention relates to improving the visibility of traffic conditions and road conditions in general surroundings of automobiles.

  In an automobile using a conventional video camera on the roof, one or a plurality of video cameras are used with the imaging direction of the video camera set obliquely downward, and an input image from the camera is used for a predetermined three-dimensional space. Spatial reconstruction means for mapping to a spatial model, and viewpoint conversion means for creating an image viewed from an arbitrary virtual viewpoint in the predetermined three-dimensional space with reference to the spatial data mapped by the spatial reconstruction means Display means for displaying an image converted by the viewpoint conversion means, and six cameras are attached to both ends of the roof front edge and the roof rear edge or in an intermediate position. Rather than displaying the captured images independently of each other, the combined input images are combined so that the entire area captured by the several cameras can be intuitively understood. Relates to an apparatus and method for displaying an image, for example, an invention of monitoring apparatus in the shop, or the vehicle surroundings monitoring apparatus as a safety confirmation of assistance in a vehicle driving on the purpose. (For example, refer to Patent Document 1.)

 In addition, for the purpose of creating a composite image in which the left and right sides of the front and rear of the vehicle are imaged with a wide angle camera with an angle of view of 90 degrees or more, and the left and right are exchanged for easy viewing in the passenger compartment. An image synthesizing unit that generates image information to generate composite image information and a display unit are provided, and the displayed image information is an inverted image obtained by inverting the horizontal position of the captured image. This is an invention that enables the user to visually recognize the vehicle and drive the vehicle. (For example, refer to Patent Document 2.)

  In addition, a hole is provided at a position slightly retracted inward from the front end or the rear end of the vehicle, and a camera mounting member disposed so as to be movable up and down by a predetermined drive mechanism with respect to the hole, and a front end of the camera mounting member When the camera is used as a video camera, the imaging means attached to the elastic mounting member can be extended from the hole to take an image of the surroundings of the vehicle. The direction in which the imaging means moves up and down is a direction inclined at a predetermined angle with respect to the vertical direction of the vehicle. When the imaging means is extended by the drive mechanism, the imaging means is located at a position protruding outward from the hole. It is an invention that is positioned. (For example, refer to Patent Document 3.)

Although Patent Document 1 is installed downward as shown in FIG. 7, it does not display images independently of each other, but intuitively understands the entire area captured by the several cameras. As described above, a camera is installed for the purpose of displaying a single synthesized image, and Patent Document 2 simply converts the image captured by simply rotating the video camera horizontally to change the vehicle interior. It is intended for visual recognition on a TV monitor. Further, Patent Document 3 is intended to visually recognize a distant situation from a road condition just before a car by installing a camera downward on the upper part of the front window.

 A conventional camera installed on the roof of a car can drive safely with an image that is not obstructed by the so-called video camera installation position blind spot or body-specific blind spot that has an imaging range of 360 degrees around the vehicle in real time and no missing parts It was extremely difficult to do this because of its purpose and means.

 In addition, the arrangement of 4 to 6 cameras on the leaf without any countermeasures for the installation position blind spot and the horizontal rotation is necessary to prevent the generation of the video camera installation position blind spot from the shape inherent to the vehicle body. Since a missing part is generated in the imaging range on the lateral side of the car without being able to do so, there is a problem that it is difficult to avoid a post-contact with a car or a motorcycle that runs side by side.

  In addition, it is necessary to synthesize a captured image while horizontally rotating a video camera installed on the roof while the vehicle is running, and to drive while visually checking the combined image information. Since it is an image that includes unsafety that can not be seen from behind, even if you can check the safety on the right side, you can not do the left side, so you can quickly take advantage of the instantaneous danger inherent in cars that run at relatively high speeds There was a problem that we could not cope.

In addition, a vehicle or a person traveling from the left and right cannot be visually recognized at the same height when installed on a bumper under the front bonnet as in Patent Document 3, and Patent Document 4 discloses a windshield. the front of the traffic situation and road conditions from the upper part from the fact that there is also put to visually recognize by a single video camera, to prevent the Crossing accident with a margin to quickly view the vehicles and people traveling from the left and right In addition, it is not an effective measure against the danger of the missing portion of the visible range due to the blind spot inherent in the conventional automobile .

  In addition, since conventional vehicles cannot view real-time images that eliminate the blind spots specific to the vehicle body and the blind spots created by the video camera installed on the roof, when driving a vehicle. Therefore, it is difficult to take appropriate avoidance measures corresponding to the danger without noticing that there is a missing part in the imaging range.

  In particular, because cars are used at high speeds, video camera installation blind spots and car-specific blind spots not only reduce the risk detection rate by only generating missing parts in the static imaging range, but also both sides of the running car. In addition, while forming a danger zone of a missing part of the dynamic viewing range, it is traveling as if erasing the imaging range with an eraser, and the danger and fear are extremely great.

  And when a vehicle running side by side while driving is in the danger zone of the missing part of the visible range, it is a collision accident that causes a parallel running vehicle by changing the course assuming that it is safe without noticing the danger There were very many.

  As described above, the present invention has been made to solve all of these problems, and the video camera group provided on the roof is transparently protected from the roof surface to the video camera in the high transparent protective equipment. Since the video signal captured by the fixture is transmitted to a monitor arranged in the passenger compartment, and a video without any missing part can be visually recognized in the video of traffic conditions and road conditions, a traffic accident can be prevented.

  In particular, the video captured by the video camera installed in the transparent protective equipment group of the video camera with an electric mirror drive device installed on the roof is adapted to the operation that the driver actually inspects and confirms safety. It is an excellent feature of the present invention that it can be transmitted to a group of monitors adjacent to each other between the ceiling peripheral part of the ceiling and the center of the ceiling or in the front part of the passenger compartment, and the image can be seen at the same time. It focuses on visualizing images taken in all directions freely and in an excellent sense of direction in real time.

The problem-solving means of the present invention includes the video camera mounting base 67 to which the video camera 82 with an electric mirror driving device is attached as the video camera transparent protective device with the electric mirror driving device provided on the roof peripheral edge portion 17, and the video camera mounting base. A transparent protective body body 24 holding 67 therein, a rotating body base 85 to which a lower end portion of the transparent protective body body 24 is attached, a rotating body 84 formed on the rotating body base 85 , and the rotating body base 84, a pivot shaft base 87 provided upright with a pivot shaft 88 fitted thereto, a mounting base 86 to which the pivot shaft base 87 is attached, and the mounting base 86 to the roof peripheral edge portion 17. A support washer 148 fixed by a U plate 149 locked by a locking groove 150 on the upper portion of the pivot shaft 88 from above the rotating body base 85 into which the shaft 88 is loosely inserted; A worm wheel 89 frictionally fixed to the upper surface of the rotating body boss 92 with a compression spring 147 interposed between the clutch guide 145 and the clutch plate 146, and the worm wheel 89 through a reduction gear group 92 and a worm 151. A video camera with an electric mirror driving device centering on a base point on the roof, characterized by rotating a transparent protective body body 24 attached to the rotating body base 85 of the rotating body 84. This is a vehicle equipped with a visual camera equipped with a transparent protective device on the roof.

  A video camera with a high image pickup position and a wide image pickup range on the roof of a car. Can be seen on a plurality of monitors in the vehicle, so the driver's safety awareness can be improved and dangerous situations can be avoided.

  By installing a transparent protective device with an electrically driven mirror drive device on the roof, the front blind, the bonnet, the front fender, etc., "the blind spot of the front left and right fields of view" and the low blind point of the eye point, Since the field of view that eliminates the influence of “, etc.” can be secured, there is no field of view that is overlooked in the safety confirmation, and the danger during traveling can be quickly recognized.

  In addition, the rear-viewer's rear view blind spot, which is a drawback of the rearview mirror, prevents the rear view from being obstructed by the rear pillar and prevents the rear view from being obstructed by the body when a person is on the rear seat. Inadvertent traffic accidents can also be prevented.

  When driving in the opposite lane of one-side traffic on one side lane, accidents involving human injury can be detected in advance because people, bicycles and motorcycles (motorcycles, motorbikes, etc.) suddenly jumping out from between traffic vehicles can be discovered. Can be prevented. In addition, since the distance between the front side of the vehicle body and other vehicles and buildings in close proximity can be easily confirmed, the vehicle can be used when passing by other vehicles or buildings in a narrow passage, or when parking in a narrow parking lot or a gap between vehicles. It is possible to prevent property damage accidents such as touching.

  A clear image of the surrounding traffic situation can be seen on the monitor, so if the vehicle suddenly slows down or stops suddenly while traveling in parallel, When a problem occurs in front of the oncoming lane when overtaking or overtaking, changing course, or passing each other, it is possible to prevent a rear-end accident, contact accident or collision accident in advance by detecting the problem in advance. it can.

  If you turn right at the intersection and the right turn vehicle is stopped in the opposite lane, you can easily find a car that goes straight on the left side of the right turn vehicle that is stopped in the opposite lane, a motorbike, etc. Since it is no longer necessary to make a right turn until a risk is easily committed, it is possible to prevent a traffic accident that collides with them.

Since the video camera transparent protective equipment with electric mirror drive device is installed on the roof and has excellent overhead view , the imaging beam is not obstructed at the periphery of the roof of the car and from directly under the car periphery. Since it has the characteristic that visibility in the distance is extremely good, the video camera transparent protective equipment with electric mirror driving device attached to each or more video cameras is equipped with each electric mirror driving device without being obstructed by any blind spots. There is an effect that it is possible to take an image by finely sharing the range of 360 degrees around the.

This also increases the oversight rate of danger occurrence due to the missing part of the imaging range due to the blind spot of the video camera installation position generated by the visual mechanism installed on the roof of the conventional automobile, and the front of the disadvantage inherent in the automobile blind spot and the left and right view, blind spot and upper view, blind spot and the rear view, a rear side and a blind spot of the side view or the like, can solve serious problems extremely have the drawback of visual function to inhibit safety check on Therefore, the effect of preventing traffic accidents is extremely large.

In addition, either the center of the roof or the position corresponding to the head of the driver sitting in the driver's seat is used as the base point on the roof, and the radial line centering on the base point on the roof crosses the roof periphery. The video camera with mirror drive and transparent protective equipment installed in the present invention is designed to accurately divide 360 degrees around a wide range of vehicles and divide the investigation area as if an excellent criminal investigation group searches for evidence. The point is that the danger can be detected as soon as possible.

  In other words, by driving a vehicle equipped with a visual camera with an accurate stratified visual effect, there is no danger in the direction of travel for an excellent sense of direction, "everyone unconsciously takes action to avoid it unconsciously" Because it can be visually recognized and measures can be taken quickly, traffic accidents can be prevented.

That the present invention is particularly superior to the conventional automobile is adjacent the monitor group view the picture captured without imaging light is shield at the periphery of the roof in real time side by side, the range of Kurumashu 360 It is possible to visually recognize the images of the monitor group that has shared the images of the above in layers. As a result, the driver's central vision and peripheral vision can be effectively demonstrated by allowing the driver to freely view the direction he / she wants to see without being obstructed by blind spots in the field of view, which is a drawback of conventional automobiles. As a result, traffic accidents can be easily prevented.

In particular, there are many traffic accidents that occur when the most necessary visual ability for human action is obstructed by the insufficient visual recognition function of the car due to the bad influence of blind spots , and it is extremely significant to improve it . In addition, the traffic accident is not only caused by one's unreasonableness or carelessness, but may be caused by unreasonableness or carelessness of the driver of another vehicle, but it is effective in both cases.

  The present invention solves the deficiencies in the safety confirmation function that are the cause of these traffic accidents, thereby reducing the number of traffic accidents caused by poor visibility due to blind spots by conventional automobile drivers.

  Therefore, the spread of the video camera equipped vehicle equipped with the video camera transparent protective device with the electric mirror drive device of the present invention makes it easy for the drivers to see unsafe conditions and dangerous conditions encountered by the traveling vehicle. It is possible to effectively prevent traffic accidents because they can be discovered, but the excellent visibility makes it possible for drivers to think of each other's safe driving and cooperate with each other to prevent traffic accidents. large.

The present invention clarifies the viewing position, viewing direction, and viewing range that are important for the viewing function of the monitor, and is a long monitor in which 9 groups of monitors are arranged side by side above and below the front of the vehicle interior. body by accidents or Crossing during traveling, and frontal collision, it is possible to prevent a collision accident or the like during or right turn at left.

  In addition, a large monitor group is installed between the left and right sides of the passenger compartment and between the ceiling peripheral edge and the center of the ceiling in consideration of visibility from the driver's seat, and the large monitor group goes straight backwards as if driving an open car. And safe driving such as retreating to a parking lot.

As described above, the present invention eliminates the missing portion that occurs in the imaging range and the visual recognition range due to the video camera installation position blind spot and the blind spot specific to the vehicle body as a drawback of the car, and as a result, accurate visual information is obtained. In conventional road traffic where poor visibility under incomplete visual information is generalized, the video camera transparent protective equipment with an electric mirror driving device of the present invention can be used for traffic of 360 degrees around the vehicle only by setting the initial imaging direction. Since the situation and road conditions can be grasped, it is much better than conventional cars .

The first system effect of preventing traffic accidents is to be optimistically interpreted as normal as much as possible even if the normal bias that misjudged the chance of avoiding danger by misjudging insufficient visual information or the visual information indicating abnormality is obtained. The video camera transparent protective equipment with the electric mirror drive device of the present invention was placed on the roof of the car for a traffic accident caused by an underestimation of the crisis caused by an optimism bias unconsciously acting on the driver's mind Because it is possible to determine the omnidirectional traffic situation centered on the car based on complete visual information without being disturbed by any blind spots and without the anxiety that has been exerted by conventional unsafe visibility. Naturally, it can correctly prevent traffic accidents .

In addition, the image of a monitor using a conventional electric rotating video camera can be taken only in the direction in which the rotating camera is facing, and is an image that is displayed by transmitting the image signal. Since an image on the opposite side of the image direction cannot be visually recognized, it is inferior in that it cannot respond instantaneously as in the present invention when danger approaches from a direction other than the imaging direction.

In addition, the visibility of the viewing range played by the shared image, which is the vehicle interior monitor effect of the present invention, and the panoramic view confirmation that the situation in the vicinity can be overlooked, due to the incomplete visibility / visibility of conventional automobiles, Since the psychological burden and restraint of all drivers who have been driving with anxiety in the prediction of danger can be eliminated, the impact of preventing traffic accidents is extremely great and the best that the present invention provides to the driver Technical services.
