Description

Camera device for 360 ° panorama shooting and its operation {Camera Device For 360-degree Panorama Shot and Method}

The present invention relates to a 360 ° panoramic camera device and its operation method, which are composed of four lenses and a CCD image sensor for capturing a limited area having a horizontal angle of 90 ° on a monitor screen. In other words, position the four CCD sensors as close as possible to reduce the distance between the blind spots parallel between the image incident line of the lens and the image incident line of the neighboring lens. Its purpose is to allow four video seams to be expressed naturally by being neglected.

According to another object of the present invention, four image signals captured by four lenses and a CCD sensor are combined into one image signal using a four-split board so that the 360 ° image can be displayed in two rows up and down on the monitor by 180 °. It is configured to be viewed on a video monitor immediately without going through a computer.

The prior art panoramic camera device is composed of a fixed hemispherical special mirror and a camera unit comprising one lens (Lens) and a photographing element (CCD) at a predetermined position under the hemispherical special mirror.

A panoramic camera having the above-described configuration is a computer which recognizes or photographs a surrounding 360 ° donut-shaped image formed on the special mirror and outputs it as an image signal by the camera unit, and receives the image output signal. And the monitor unit expands and displays the panoramic image by using digital image signal processing (DSP) technology and image editing software technology by a computer function.

The above-mentioned conventional panoramic camera has the advantage of simultaneously capturing 360 ° omnidirectional images with one lens and a CCD sensor. However, the size of the subject to be viewed is displayed so small that it is difficult to meet general surveillance purposes. There is a limitation of the resolution to such a degree, and there is a problem such that it is difficult to completely remove distortion or distortion of the image.

Therefore, the shortcomings of the above-mentioned panoramic camera are the panoramic camera which directly photographs 360 ° omnidirectional image by arranging four or a plurality of lenses and a CCD.

At this time, the image incident line of each lens is made in parallel with the image incident line of the neighboring lens, the camera is connected to the rear part of the lens, and each image photographed is transmitted to the computer.

The image transmitted as described above may be represented as a panorama image by combining the image of the first camera and the image of the second, third, and fourth cameras on a computer monitor by an image processing board mounted in a computer and image editing software.

However, in the camera device constructed by the above method, each camera unit is fixed and installed independently, so that when the assembly / transportation and use are performed, external micro-impacts may cause fluctuations in the focus of the camera and the lens and the image incident line. Due to the disparity of parallelism of the image incident lines of the lens, it is difficult to combine the images due to overlapping or spaced apart image lines. Therefore, the image cannot be expressed in a panorama format.

And since the conventional method has a camera size, no matter how small a camera is used, the connection part of the image is cut in the panoramic camera due to the increase in the distance between the parallel and rectangular portions existing between the lens and its neighboring lens. There was this.

In addition, since the video signal captured by each camera must be transmitted to the display computer unit, unnecessary cost is incurred because each cable is installed or each transmission device must be installed for each camera. In order to implement a panoramic image on a monitor, a computer, an image processing board, and image editing software have to be used.

Since the panoramic image implemented as described above should be unfolded horizontally, and the images captured by the four cameras should be unfolded horizontally when viewed with a monitor, the width is essentially narrowed, which causes the object to be small and loses clarity, thereby accurately and quickly Could not grasp.

When the video signal is viewed on a monitor, the screen size of the monitor is 4: 3 while the images captured by the four cameras must be horizontally stretched, so that the length is longer than the width as shown in FIG. Because only part is used, there is a disadvantage that the unused space is left and the screen efficiency is reduced.

Applicant has applied for a panorama photographing monitoring device and its method (2002 Patent Application No. 0004726) in order to solve the above problems, look at the above design as follows.

In the 360 ° panoramic monitoring device configured to divide the image incident angle formed by several lenses at a predetermined angle,

The number of lenses and CCD image sensors are configured on the same horizontal plane by the number of 360 ° divided by the image incident angle, and the number of lenses and CCD image sensors increases, so that the number of lenses and CCD image sensors is increased. Shooting by direct cameras with two cameras and lenses to improve resolution, eliminate screen distortion, and prevent the panoramic image from being generated due to the fluctuation of the image incident angle formed by the minute movement of the lens. The company will manufacture a surveillance device for panoramic photography, including a barrel consisting of a polyhedron for fixing and placing image sensors.

However, the above method has a disadvantage in that a cable is installed in each camera, and each transmission device must be installed for each camera. Therefore, the transmission is difficult and there is a complicated disadvantage due to the unnecessary number of transmission devices and cables. Receiving the transmitted signal to the computer, there was a problem that the manufacturing cost is expensive by using an unnecessary expensive computer, and in the panoramic image display, the bottom of 360 ° is spread out in a single line, which causes the problem of inefficient screen efficiency. .

The present invention relates to an improved design related to 2002 Patent Application No. 0004726 (a panorama photographing monitoring device and method thereof) devised by the present applicant. If the distance is minimized, the distance between the image and the image is hardly felt if it falls more than a certain distance (approximately 4m) .Only one image signal is obtained by combining the image signals generated by the four lenses and the CCD sensor into one. I could send it.

In other words, the CPU board is manufactured in the shape of 90 ° fan bone, but the CCD board with the CCD sensor is installed at right angles to the narrow part to minimize the gap between the CCD sensor and the CCD sensor. By combining the video signals into one, it is easy to transmit.

In addition, by transmitting the transmitted video signal, the total 360 ° image is displayed on the monitor with two rows of 180 ° range image on the monitor, and the maximum resolution is maximized by maximizing the subject on the monitor. As it can be used to connect to a video monitor, the present invention will be described in detail by the accompanying drawings as follows.
