In addition, it is possible to automatically change the zoom and focusing settings of the lens and the azimuth and altitude settings of the pan/tilt based on the information provided from the location detection sensor without image analysis by ISP (Image Signal Processor), enabling fast and accurate object recognition. For high-speed zooming and focusing of a camera that continuously provides high-quality images by tracking and predicting moving objects at high speed, which can provide high-quality images continuously by tracking and predicting moving objects It relates to an apparatus and a method for high-speed zooming and focusing of a camera using the same.

As the demand for monitoring a wide area using cameras increases, video analysis is based on cameras that take images of multiple objects and automatically check the problem situation in the required area and instruct immediate response through video analysis using AI technology. and system operation solutions are provided.

However, in order to quickly track multiple objects in a wide area and provide accurate images, a fast object tracking technology and an accurate image acquisition technology for each object are required.

In order to track a fast object with an accurate image, a technology is required to quickly adjust the optical lens of the camera according to the movement of the object to secure the optimal zoom state and precise focus as quickly as possible.

In order to accurately photograph a distant target object in the required size from the camera, the camera lens is adjusted to an appropriate magnification, and then the work of focusing on the exact target point through fine adjustment is performed either manually or automatically.

Even recently released mobile phone cameras are providing SW that automatically adjusts the distance and focus according to the movement of the object when designating a target object or person, and takes a picture.

The background of the present invention is to propose an invention to satisfy the demand for a technique for securing high-quality images by tracking such a moving object at high speed.

When a target object is detected within a specific monitoring area, the zoom function of the lens is adjusted to ensure that the size necessary for recognizing the object is secured within the image.

When such a zoom function is performed, a fine focus is adjusted to create an optimal image condition.

The process of performing the above function proceeds in the order shown in FIG. 1 . In other words, it goes through the stages of surveillance, discovery, scaling, and tracking.

In the above process, an object in the discovery stage needs a stage of enlargement and adjustment according to the distance and size of the object found, and after this process is successfully performed, it proceeds to the stage of tracking. In order to perfect monitoring and tracking, it is necessary to complete the expansion and adjustment time as quickly as possible in the shortest possible time. The present invention seeks to provide a technique that meets these needs.

As a general method used to magnify a found object, a method of checking the focus of an object captured in a camera image is used. The way to check the focus of an object is to sequentially check the focus in the ISP (Image Signal Processor) of the camera and find the optimal focal length.

This method enables fast tracking by accurately focusing in the case of a short distance, but it takes a lot of time to find the optimal condition by the camera itself when there are various other objects in the vicinity or a distant object. cause

2 is a general flowchart illustrating a process of photographing and transmitting an image of a moving object using a camera. As described above, the object tracking method using the conventional lidar shown in FIG. 2 is effective for tracking a fixed object, but has the following problems for a moving object.

first. After the lidar measures the target object, it transmits related information to the pan-tilt, camera, and lighting, and adjusts each device according to the information received from each of the pan-tilt, camera, and lighting. At this time, a certain amount of time is required.

second. Accordingly, there is a problem in that a distorted image is secured because the captured image is captured in a state in which the distance, altitude, and direction of the object are deformed by the required time.

third. This phenomenon causes a large difference according to the speed of the moving object and the target number of moving objects.

SUMMARY OF THE INVENTION The present invention has been proposed to solve the problems of the prior art, and is intended to provide a technology capable of continuously providing high-quality images by tracking and predicting a moving object.

Let's see.

As shown in Figure 3,

An apparatus for high-speed zooming and focusing of a camera according to the present invention

A positioning sensor 10 for measuring distance, altitude, direction, and moving speed of a moving single or multiple target objects 100 in real time;

Movement prediction information of the target object 100 is calculated and extracted based on the current location of the target object 100 measured by the position detection sensor 10 and information on an expected movement path, and the extracted An operation control unit 20 that controls device condition settings by transmitting control signals to the camera module, illuminator, and pan-tilt according to movement prediction information;

A data storage unit 30 for storing current information and movement prediction information of the target object 100 extracted through the operation control unit 20 in real time;

A camera module 40 forcibly correcting the focus of the camera lens according to the control signal of the operation control unit 20;

The present invention can provide a high-quality image captured through high-speed zooming and focusing of the camera by predicting the moving point of the target object 100 in advance through the device for high-speed zooming and focusing of the camera.

Airplanes, tanks, drones, etc. move while forming a certain trajectory, so it is rare to suddenly change direction or change speed rapidly.

Therefore, in the present invention, after collecting data on the past moving speed, moving distance and speed of a moving target object, and predicting the moving direction and moving distance of the target object through an arithmetic device based on the collected data, The information calculated in this way is transmitted to the camera, and the camera enables continuous sharp focus according to the moving object.

Looking at the process of photographing and transmitting an image of a moving object using a conventional camera shown in FIG. 2 related to the technology of the present application, the process proceeds as follows.

1. Measure the distance, altitude, direction, and speed of the target object using the lidar sensor, and transmit the obtained measurement information to the control system.

2. When measurement information is transmitted from the lidar sensor to the control system, among the measurement information, altitude and direction information is transmitted to the pan-tilt and distance information is transmitted to the camera.

3. Based on the information transmitted through the control system, the pan-tilt corrects the azimuth and altitude, and the camera and lighting forcibly correct the lens focus according to the distance information.

4. The camera whose lens focus is forcibly corrected captures an image of the target object and transmits it to the control system.

This conventional method is effective for tracking a fixed object, but has the following problems when applied to a moving object.

It takes time for the lidar sensor to measure the target object, transmit the measured information to each of the pan-tilt, camera, and lighting devices, and adjust the pan-tilt, camera, and lighting devices according to the received measurement information. It takes

Therefore, there is a problem in securing a distorted image because the captured image is captured in a state where the distance, altitude, and direction of the object are deformed by the required time. Moreover, such a phenomenon causes a large difference according to the speed of the moving object and the number of target moving objects.

In the device for high-speed zooming and focusing of a camera according to the present invention shown in FIG. 3, the target object 100 moving at a long distance is '(1)'->'(2)'->'(3)' sequence. The position is moved, and the target object 100 is located at the point '(4)' after a certain time elapses, and the camera lens 401 is aligned with the expected object expected to be located at the point '(4)'. ), the altitude and direction of the illumination lens 501 and the pan/tilt 60 are reset.

More specifically,

The current location and movement direction information of the target object 100 is acquired through a LIDAR sensor, and based on the information obtained in this way, analysis and calculation are performed to determine the focal length of the lens of the camera and lighting when the target object 100 will move in the future. By setting it in advance at the point where it is expected to be, it is possible to cover the physical operation delay speed of the lens, and it is possible to quickly track and shoot a moving object, as well as to stably secure high-quality images. .

That is, when the technology proposed in the present invention is applied, the moving path of the target object 100 is predicted in advance and the lens focus of the camera and lighting is forcibly corrected, thereby maximally eliminating the physical operation delay time of the lens. It is possible to provide fast, accurate, and clear high-quality image information about

After accurately measuring the current distance information, altitude, and azimuth information of the remote target object 100 within an allowable error range through a positioning sensor and simultaneously photographing the information through a camera, the information about the remote target object 100 Information about the current location and expected movement path and captured image information are transmitted to the operation control unit 20 .

The operation control unit 20 includes an image analysis unit 201 that analyzes the captured image while tracking the movement of the target object 100 at high speed through the camera module 40;

Information about the current location and expected movement path, including the distance, altitude, direction, and movement speed of the target object 100 during movement tracked and photographed by the camera module, provided through the location sensor 10, and , a data collection unit 202 for collecting data on the image information provided through the image analysis unit 201;

A prediction operation unit 203 that predicts an expected moving point for the moving target object by performing an operation based on the information collected by the data collection unit 202;

A target determination unit 204 for determining a point with the highest accuracy among movement points predicted through the prediction operation unit 203 as a target point;

The information on the expected movement point determined through the target fixing unit 204 is transmitted to the camera module 40, the illuminator 50, and the pan-tilt 60, and the preset lens focus and azimuth and altitude of the pan-tilt are recalled. It includes an information transfer unit 205 that controls to reset according to the expected movement point.

The location detection sensor 10 refers to a sensor capable of measuring an azimuth angle and a distance value for a measurement object, and a specific example includes a LIDAR sensor or a radar sensor.

As shown in FIG. 3, when the distance information, altitude, and direction information for the expected object '(4)' derived through the operation control unit 20 is confirmed, the determined information is transferred to the information delivery unit 205. It is transmitted to the camera module 40, the illuminator 50, and the pan/tilt 60 through.

As the camera module 40 is shown in FIG. 4,

A camera lens 41 including a lens adjustment motor 411;

A CMOS image sensor (CIS) 42 that converts light entering through the camera lens 41 into an electrical image signal;

An image signal processing device (ISP) 43 that performs image processing on raw data output from the image sensor (CIS) 42;

A camera control unit 44 that controls the entire driving of the camera module 40;

It is connected to the camera control unit 44 and stores a value obtained by converting focus information provided through the operation control unit 20 into physical focus information of a lens in advance, and stores a program necessary for performing operations of the camera control unit 44. and a memory 45 for temporarily storing the image input through the camera lens 41.

At this time, the camera control unit 44 operates the lens adjustment motor 411 of the camera lens 41 according to a control signal transmitted from the operation control unit without going through an image analysis process by the image signal processing unit (ISP) 43. It is configured to forcibly set the zoom and focusing states of the camera lens by controlling.

The camera control unit 44 constituting the camera module 40 is configured according to the situation among the lens driving information for focus transmitted from the image signal processing unit (ISP) 43 and the focus information transmitted from the operation control unit 20. It can be selected and controlled by determining the physical focus position of the camera lens 41 .

Whether or not to select between the focus value transmitted from the image signal processing device (ISP) 43 and the predicted value transmitted from the operation control unit 20 is selected according to the moving speed or change content of the target object.

The speed or change of movement is determined based on the real-time information provided by the operation control unit 20, and the actual value can be optimized according to the situation and application.

For example, when the speed of the target object is 50 km/hr or less, ISP information is used, and when the speed exceeds 50 km/hr, the predicted value provided through the operation control unit 20 is used.

In addition, the camera control unit 44 finds a conversion table value stored in the memory 45 that matches the focus information provided through the operation control unit 20 and converts it into an optimal focus position value of the lens, and uses the converted position value as a reference. It operates the motor attached to the lens to adjust the focus of the lens.

Next, a high-speed zooming and focusing method of a camera using the device for high-speed zooming and focusing of a camera according to the present invention will be described.

Detecting single or multiple target objects moving within the monitoring area through a positioning sensor, and measuring the distance, altitude, direction, and moving speed of the moving target object in real time through the positioning sensor (S10) Wow,

Transmitting the information measured by the position detection sensor to an operation control unit in real time (S20);

Based on the information measured by the position detection sensor in the operation control unit, information about the movement prediction point of the target object is extracted, and the information extracted in this way is transmitted to the camera module, illuminator, and pan-tilt, so that the camera and lighting Forcibly correcting the lens focus according to the extracted information and at the same time forcibly correcting the azimuth and altitude of the pan/tilt (S30);

Forced zooming and focusing of the expected movement point of the target object in a state in which the imaging angle of the pan-tilt is varied according to the control signal of the operation control unit and the focus of the lens of the illuminator and the camera module coupled with the pan-tilt is forcibly corrected and taking a picture (S40).

The apparatus and method for high-speed zooming and focusing of a camera according to the present invention presented through FIGS. 3 and 4 can be effectively applied according to a single object or multiple objects, as shown in FIGS. 5 and 6 .

5 is a schematic diagram illustrating a process of tracking a single object by an apparatus for high-speed zooming and focusing of a camera according to the present invention.

The prediction process for a single object through the device for high-speed zooming and focusing of a camera that tracks and predicts a moving object shown in FIG. 5 at high speed and continuously provides high-quality images is as follows.

First, when a target object (object 1) is found within the monitoring area, the position detection sensor 10 tracks the target object (object 1). The distance to the target object, direction, altitude, and speed information obtained through the position detection sensor 10 are transmitted to the operation control unit in real time.

The operation control unit calculates and processes the expected movement point of the target object based on the distance, direction, altitude, and speed information to the target object provided through the position detection sensor 10, and thus calculates and processes The prediction information confirmed through is transmitted to the camera module 40, the illuminator 50, and the pan-tilt 60, and device conditions are newly set based on the prediction information thus transmitted.

In accordance with the newly set conditions, the high-speed zoom and focusing of the camera are performed in the photographing unit 40, the illuminator 50, and the pan-tilt 60, and high-quality photographing is performed according to the moving path of the target object (object 1). The video can be continuously provided.

At this time, it is also possible to select and set excellent information by comparing the focus accuracy and prediction information provided through the operation control unit with the focus accuracy and prediction information obtained by image analysis of the ISP.

And, when the moving speed of the target object (object 1) is slow, a focus function built into the camera itself may be used. When the movement is fast, the focus of the camera lens is forcibly adjusted according to the prediction information presented in the present invention, and shooting is performed.

The prediction process for multiple objects through a device for high-speed zooming and focusing of a camera that continuously provides high-quality images by tracking and predicting moving objects at high speed is as follows.

As shown in FIG. 6, the multi-object tracking process of the apparatus for high-speed zooming and focusing of a camera according to the present invention is shown in FIG.

As an example, since multiple objects of object 1 to object 3 can be simultaneously tracked by the positioning sensor 10, information on multiple objects can be obtained in real time, and thus multiple objects can be tracked in real time. It is possible to secure the expected movement position for the target in advance.

Therefore, when moving from target 'object 1' to target 'object 2', the estimated position of target 'object 2' already obtained can be transmitted to the camera, lighting, and pan-tilt, enabling quick focusing on target 'object 2' and then moving to target 'object 2'. When moving to 'object 3', focusing is performed quickly using the expected movement information of the target 'object 3' already secured as described above.

According to the present invention, through the apparatus 1 and method for high-speed zooming and focusing of a camera, it is possible to secure accurate and clear images while maximally eliminating delay time.

In addition, it can provide a great effect as an ultra-high-speed image focus securing technology for tracking multiple moving objects and securing images.

When trying to track multiple objects through a single camera, it is not easy to perform multi-tracking because the tracking speed is very slow in the conventional focusing method based on viewing images.

In the present invention, by applying the location detection sensor technology, it is possible to perform multi-tracking, which was difficult to apply through the conventional method. In addition, even if each object moves at a different speed, multiple tracking of multiple objects is possible because prediction information for the object is immediately input.

In the present invention, using statistical prediction information based on measurement data continuously obtained using a location detection sensor may cause a phenomenon in which accuracy is lowered in some cases.

If predictable,

As shown in FIG. 7 , this is the case when the speed of the moving object is slow and when the moving object approaches.

In this case, the distance error range of the location detection sensor may not follow the auto focus speed and accuracy performance of the camera. In preparation for such a case, a system equipped with a fine adjustment technology is provided, in which a method of converting a focus to a camera's own focus adjustment function in parallel after securing a focus with a lidar is provided.

That is, the camera module 40 first automatically controls the focus of the camera lens 401 according to the control signal of the operation control unit 20,

It is switched to the camera module self-focusing function, and the secondary focus of the camera lens 401 can be finely adjusted.

Through this, it is possible to provide an ultra-high-speed focus securing technology that can optimally use both the advantages of positioning sensors including LIDAR and RADAR and the advantages of cameras.

Conventionally disclosed technologies are applied in a state where the measurement object is moving and the measurement target is fixed, but in the present invention, the moving object is set as the measurement target and information on the moving direction of the measurement target is obtained by using a location detection sensor. It is possible to cover the physical operation delay speed of the lens by predicting the focal length for the point where the measurement target will be located after a certain period of time based on the information obtained in this way and adjusting the focus of the lens in advance. , high-speed tracking and prediction of a moving object to continuously provide high-quality images, so it has high industrial applicability.
