Description
The present invention relates to an ultra-high magnification camera image sensing apparatus, and more particularly to an ultra-high magnification camera image sensing apparatus capable of automatically capturing an image at a desired distance by automatically controlling a movement speed of a moving image according to an imaging distance of an ultra- To an image sensing apparatus.
Generally, telescopes are used at distant sites to observe skyscrapers, dams, rugged mountains, forest fire monitoring and emergency rescue, long-bridged or military targets, or to observe difficult or dangerous access points In order to obtain more accurate information, it is inconvenient to approach the appropriate position for observing and to observe with a telescope, and if there is continuous observation, it is necessary to stay there and check the object frequently. However, in recent years, the inconvenience described above has been solved by the development of the unmanned surveillance camera.
Typically, the unmanned surveillance system will be able to easily understand the concepts and functions of the unmanned camera for detecting unauthorized cameras for speed violation detection, preventing various types of crime and various types of crime, for detecting traffic conditions on the roads or preventing speeding. Unmanned surveillance cameras consist of a stationary unmanned surveillance camera fixed to a certain position according to its shape and a movable unattended surveillance camera which can observe the camera by moving the angle of the camera vertically and horizontally. And can be monitored through the monitor.
The unmanned observation system described in the present invention is an unattended observation system having a high magnification zoom function capable of observing or monitoring a very long distance in a range of about 5 to 20 km. And the concept of the unmanned surveillance system is similar to that of the conventional unmanned surveillance camera.
Therefore, if the unmanned observation system is used for military purposes, it can acquire various information such as the history of the enemy, the size of the firepower, the movement of the troops, and the weapon, thereby effectively enhancing the tactical strategy of the military and various operations. In addition, it can be widely used variously such as cracks of dams, abnormalities of bridges, abnormalities of high-rise buildings (outer walls), and rescue activities of forest fires and victims.
The most important advantage of the unmanned observation system or the unmanned surveillance system is that it is very easy to grasp the change, movement, or situation of the land feature in a difficult or difficult area.
However, in order to achieve the object, remote control of the system must be performed remotely, so that noise control is required without noise, and a reliable unmanned remote control method and system are required. In particular, The telescope must be re-aligned exactly to the stored coordinate location when re-aligning the telescope with the coordinates to be observed continuously.
In other words, if an unattended observation system is installed in the outdoor and a telescope is selected at a remote site to continuously and intensively observe a specific object to be observed, the focusing of the telescope is adjusted and the coordinate value of the position is stored in the memory device If necessary, the telescope should be repositioned to the stored coordinate location to periodically look at changes in the situation according to the time difference.
However, if the telescope is not correctly aligned to the position of the stored coordinate value, unnecessary and meaningless image data is captured. That is, it is very important to arrange the telescope so that the telescope is aligned exactly with the position of the coordinate value stored when the telescope is reordered, because the error range of the coordinate point outside a few kilometers is very large even if the high magnification telephoto lens has a slight deviation in the alignment position of the telescope.
The present invention solves the above problems by analyzing the distance of the image pickup point of the ultra high magnification camera and slowly rotating the camera as the distance is longer and rotating the camera more rapidly as the distance is closer to obtain the image So that the user can accurately capture the image.
