Description

Video camera capable of realizing intelligent image association of multiple cameras

Technical Field

The utility model belongs to the technical field of intelligent monitoring, relates to a camera with a cradle head on the upper part and a panoramic camera on the lower part, and particularly relates to a camera capable of realizing intelligent image association of multiple cameras.

Background

Whether security requirements or operation requirements are not separated from using a large number of video cameras, as the number of cameras is increased, the data volume generated by the cameras is increased, and the functional requirements of people on the cameras are increased, the cameras are gradually changed into intelligent analysis equipment from early-stage simpler image sensing tools, and more cameras are locally provided with the calculation capacities of a CPU (Central processing Unit) or an NPU (non-point processing Unit) and the like, so that a user is helped to analyze data analysis events. However, the current camera has very limited capabilities, even if the cameras are very close to each other, the sharing and association of data and information cannot be performed, and the process that a user typically pays attention to a complete event often does not occur only in a single camera, but may span multiple cameras, which requires that the data between the adjacent cameras be able to be associated. The current security protection or AI type camera more uses gun type, cloud platform, design scheme of wide angle, just can't be in the same space with a plurality of cameras together in the hardware ability, then can't do further data analysis yet. This short board also makes the AI requirements urgent for many customers impossible to do and solve because of the data across the cameras.

To solve the above problem, manufacturers often choose three schemes: 1. calibrating a camera in the space; 2. performing global analysis and search for all cameras; 3. and using a plurality of panoramic cameras to perform offline space modeling. The problem of the three schemes is serious, so that any scheme cannot be accepted by consumers in the market at present: 1. the calibration of cameras in space requires the advance knowledge of the position, direction and space information relationship among the cameras. The requirements on the field measurement precision and the personnel professionality are very high, and the front work is abandoned if the camera is displaced in the later operation period, so that the project implementation cost of the scheme leads to unacceptable projects; 2. the real-time data volume of the cameras is very large, hundreds of online cameras are required to be searched and analyzed across the cameras, meanwhile, the requirement on the load of a server is high and the requirement on data transmission is also high by analyzing the data, in addition, even if the same targets or the same events of a plurality of cameras are analyzed by the scheme, the effective association of a plurality of fragments cannot be carried out, the advanced analysis and the processing of the events still cannot be carried out, and meanwhile, because a large AI server is required to be installed in front, the method is a threshold which cannot be ignored for many clients; 3. the panoramic camera contains relatively full spatial information, so 3D modeling can be carried out on the space under the support of an algorithm, a plurality of adjacent panoramic cameras can splice the models for correlation, but the scheme is realized in an off-line environment when the conversion of the space models is more, the models cannot be updated in real time because the calculation amount is extremely high, and meanwhile, the resolution and the definition of each specific information are insufficient because the panoramic camera contains large information, so that the event is difficult to carry out effective AI processing even though the event can be correlated across the cameras.

The panoramic camera has the object capturing and tracking capability, but has poor imaging quality; and the cradle head has higher imaging quality. Therefore, there are related technical solutions in the prior art for combining a panoramic camera with a pan/tilt head.

For example, the utility model patent with application number 201720683043.3 discloses a linked vehicle-mounted panoramic camera, which comprises: the system comprises a protective cover, a mounting plate, a PTZ (pan-tilt-zoom) camera, N cameras, a gray filter, a power panel, a signal processor, a CMOS (complementary metal oxide semiconductor) image sensor and an electric lifting rod, wherein the PTZ camera can track a target in a panoramic view and acquire detailed information of the shot target, and a monitoring system can ignore a small monitoring blind area through linkage of the panoramic camera and the PTZ camera. The spliced panoramic camera has the advantages of high pixels, small distortion and uniform pixel distribution: the circuit board is used for controlling the N lenses to collect real scene data 360 degrees in an all-around mode, the high-definition lenses and the image sensors are respectively installed on the fixed support according to fixed angles, effective pixels of the image sensors are utilized to the maximum extent, and compared with the fisheye lenses, the spliced panoramic camera can shoot pictures with higher quality.

In addition, the utility model patent application with the application number of 201410369845.8 also discloses a video moving target monitoring method based on a multi-dome camera linkage structure, which comprises the steps of firstly adopting a panoramic monitoring camera and a plurality of cloud platform close-up tracking cameras arranged at different positions, realizing linkage between the panoramic monitoring camera and the close-up tracking camera by using a computer, namely establishing a position corresponding relation of each point in a scene picture in video pictures shot by the plurality of close-up cameras and the panoramic camera respectively, and determining the orientation of the close-up camera according to the positions of targets in the panoramic camera; performing behavior detection on the target in the monitoring area by using the panoramic monitoring camera, namely separating the moving target from the background of the scene by using an image and video processing method to obtain information of the position, the moving direction and the speed of the intrusion target; then tracking the target detected in the step 2 by using a template matching method between frames of the video to obtain the motion trail information of the target; and finally, when the tracking target passes through a limit set by a user or enters an area set by the user, the panoramic monitoring camera transmits the obtained target motion track information to all the close-up tracking cameras through the linkage relation established in the step 1, and the rotation of the control holder drives each close-up tracking camera to rotate so as to track the target. According to the panoramic monitoring system, a multi-camera linkage structure is adopted, a fixed camera is used for completing a panoramic monitoring task, targets entering a monitoring area are identified, and the position, the running speed and the running direction of the targets are determined. Then, when a target passes through a boundary set by a user or enters an area set by the user, the panoramic monitoring camera completes detection of the entering position, the moving track and the speed of the invasion target, converts the entering position, the moving track and the speed into control information and sends the control information to a holder for erecting a close-up tracking camera, a plurality of cameras which are erected on rotatable holders with two degrees of freedom at different angles of a monitoring scene are driven, the resolution of the cameras is automatically adjusted, the target is tracked, the target object in a shot video picture is ensured to be clear enough for the user to recognize, and close-up tracking of the locked target is completed.

According to the 201410369845.8 patent application, through linkage between the panoramic monitoring camera and the plurality of pan-tilt close-up tracking cameras arranged at different positions, the orientation of the close-up camera can be determined according to the position and the motion track of the target in the panoramic camera, so that close-up tracking of the locked target is realized, and a sufficiently clear picture is obtained; however, such a panoramic camera requires a plurality of holders to be provided, and the overall cost is greatly increased. In the 201720683043.3 patent application, the panorama and the pan-tilt are configured on one camera, but the pan-tilt is not associated with the panorama, and the view angle of the pan-tilt is limited, so that the pan-tilt has a large blind area when acquiring a clear picture.

The third cradle head support frame 21 is provided with a cradle head horizontal motor 8, and the cradle head horizontal motor 8 is connected with the slip ring 6 through a gear set. When the horizontal motor 8 drives the gear set to rotate, the rotating gear set rotates the slip ring 6, the first holder support 23, the second holder support 22 and the structures thereon on the third holder support 21. The specific connection modes of the horizontal motor 8, the gear set and the slip ring 6 of the pan-tilt can be directly referred to the specific connection modes of the existing motor, gear set and moving device, and can be directly converted from the prior art by a person skilled in the art.

The first holder support 23 and the third holder support 21 are also provided with a light guide ring 4 and an annular lamp panel 5 which are sleeved outside the second holder support 22 and the slip ring 6 in a stacked mode, the annular lamp panel 5 is provided with a 360-degree annular lamp belt, and the 360-degree annular lamp belt comprises at least 12 lamp beads capable of controlling colors and brightness independently.

The reason for setting more than 12 lamp beads is that: the angle accuracy expressed by the lamp is at least 30 degrees, otherwise, the display effect cannot meet the requirement. Meanwhile, 24 lamps (15 degrees) and 36 lamps (10 degrees) or even higher can be realized for guaranteeing finer angle expression.

In addition, the working states of the device can be simultaneously controlled by different colors and brightnesses, and the working states comprise:

(1) Displaying the rotation angle of the cradle head (the lighting of the lamp in the corresponding direction);

(2) Displaying the angle detected by the panoramic object (the lamp in the corresponding direction is lighted);

(3) Displaying the angle of the sound sensing position of the microphone (the lamp in the corresponding direction is lighted);

(4) Displaying the type of algorithm (specific color) operated by the camera;

(5) Displaying the working state of the camera, off-line, alarm, networking, etc. (specific display state);

Meanwhile, the annular lamp belt is 360 degrees, so that the working state can be conveniently known at any angle.

The lower part of the third cradle head supporting frame 21 is fixedly connected with the panoramic camera. The panoramic camera comprises a panoramic module 18, a panoramic shell 12 is arranged outside the panoramic module 18, and a panoramic front cover 16 and a panoramic rear cover 11 are respectively arranged on the front side and the rear side of the panoramic shell 12; the bottom of the panoramic shell 12 is provided with an infrared lamp panel 15, an infrared protection cover 14 and a first infrared cover 13 in sequence. The lens protection rings 17 are arranged outside the panoramic front cover 16 and the panoramic rear cover 11. Still include second infrared lid 7, second infrared lid 7 is located between third cloud platform support frame 21 and the panorama shell 12, and third cloud platform support frame 21 below has connected gradually connecting plate 20, mainboard 19 and loudspeaker subassembly 10 to with connecting plate 20, mainboard 19 and loudspeaker subassembly 10 cladding between second infrared lid 7, panorama shell 12 and third cloud platform support frame 21. The panorama module 18 is a VR class binocular panorama module or a monocular downward panorama module (i.e., a single-fisheye panoramic lens or a back-to-back binocular panoramic lens). The infrared lamp panel assembly 9 is installed on the connecting plate 20, and the cradle head horizontal motor 8 is also installed on the connecting plate 20.

Panoramic (i.e., panoramic camera, the same applies below) light supplementing system:

in order to ensure sufficient light supplement at the dim light, infrared lamps (namely, the annular lamp panel 5 and the infrared lamp panel 15) are arranged around and below the camera.

In order to ensure perfect light filling but no exposure under various flexible environments, each infrared lamp can adjust power so as to adjust brightness to uniformly fill light.

The light supplementing of the visible light can influence surrounding targets and is bad for eyes, so that the equipment is not provided with panoramic full-color light supplementing, but a visible light lamp capable of adjusting power is additionally arranged on the cradle head, on one hand, the light supplementing of the environment light can be realized when full-color images are required to be watched, and on the other hand, sound and light alarming can be realized by matching with sound in some specific monitoring scenes.

Panorama + cradle head image quality match:

in this embodiment, the reason why the single-fisheye panoramic lens scheme or the back-to-back double-fisheye panoramic lens scheme is selected is as follows: panorama allows recording and analysis of all events within range with relatively low accuracy, without missing even if surrounding colleagues have multiple events.

(1) The reason for selecting the single-fish-eye panoramic lens scheme: if the angle of the camera is higher, most of the events are covered below the horizontal line of the equipment, so that the capturing of pictures can be satisfied by using the single-fish-eye panoramic lens which is arranged downwards

(2) The reason for selecting the back-to-back double-fisheye panoramic lens approach: if the angle of the camera is not too high or the camera has analysis and monitoring requirements on the events above the level of surrounding equipment, the picture without dead angles of VR vision can be captured by using the minimum lens in a back-to-back double-fisheye picture splicing mode, and the view angle of 360 degrees x360 degrees can be achieved.

The reason for selecting the single-lens fixed focus scheme or the single-electric zoom lens scheme or the multi-lens digital zoom scheme is that the cradle head module can accurately capture and snapshot a single event although a dead angle-free picture cannot be captured, the requirements of AI analysis are met by better image quality, and details of the event can be judged conveniently and better.

(1) The reason for selecting fixed focus lenses is as follows: the size of the fixed focus lens is small, the fixed focus lens can be optimally matched with the structural design of compact equipment, and the proper resolution is selected to meet the requirements of monitoring and AI analysis.

(2) Reasons for selecting the power zoom lens: although the optical design size of the electric zoom lens is larger, the zoom lens can better realize flexible switching of a plurality of focal lengths and accurate focusing on a target, and the image quality in the focal length switching process is advantageous.

(3) Reasons for selecting the multi-lens digital zoom scheme: the choice of a multi-lens combination with 2, 3 or more different focal segments is more flexible in terms of parameter design and more compact in terms of structure than an electric zoom lens. And the pictures of a plurality of focal segments can be simultaneously saved by capturing pictures simultaneously by multiple lenses, so that later-stage searching and AI analysis are facilitated.

By matching the panorama with the holder, any picture which occurs in the space covered by the equipment can be ensured to be captured by the panorama, surrounding events can be perceived like a radar by means of AI processing capacity in the equipment, the equipment can mark the angle of the events, then the holder is controlled to rotate to a designated position to capture each event one by one with high precision, and the details of targets can be captured and analyzed more deeply by the AI processing capacity.

Low resolution (7 meters to 10 meters satisfied) average each device can cover around 300 square meters and the pan-tilt screen achieves the target analysis capability.

(1) 4M/5M panorama+1.3M/2M/3M/4M/5M;

(2) 4M/5M panorama+2M2M/3M 3M;

high resolution (more than 10 meters is satisfied) average each device can cover more than 1000 square meters and the pan-tilt picture reaches the target analysis capability.

(1) 8M/12M panorama+4M4M/3M 3M;

(2) 8M/12M panorama+2M2M2M/2M2M4M;

(3) 8M/12M panorama+2M/3M/4M/5M/8M.

In this embodiment, a panoramic view and a pan-tilt up-down structure are adopted, and the pan-tilt is under the following conditions:

the camera head can horizontally rotate 360 degrees without limit and rotate up and down with limit relative to the panoramic fixed capturing dead angle-free picture of the equipment;

because dead angle areas exist in the cradle head and the panorama of the equipment, the equipment has options;

the built-in AI chip can facilitate the matching of the panoramic picture and the cradle head picture;

the relative position between the panorama and the cradle head is very important, and the important capabilities of the panorama and the cradle head such as picture calibration precision, picture linkage, target distance discrimination and the like are related.

The principle of panoramic and pan-tilt linkage is as follows: panorama can capture pictures without surrounding dead angles but there can be limitations in resolution and sharpness that result in insufficient precision for certain specific events, thus the pan/tilt/zoom picture is advantageous. The panoramic picture and the cradle head picture can be coordinated by utilizing the built-in AI chip operation algorithm, thereby not only meeting the requirement that all surrounding events are acquired without missing, but also ensuring the capturing of high-quality pictures of specific targets.

Firstly, due to the limitation of a mechanical structure, the rotation of the cradle head has no dead angle in the horizontal direction, but has an upper or lower rotation dead angle area in the vertical direction. Because panorama imaging module and cloud platform formation of image module can't make integrated one set, so the structure of cloud platform camera also can have partial shielding to a certain direction of panorama. And the panorama module and the cradle head module need to be designed in a structure as compact as possible, otherwise, the linkage accuracy between the panorama and the cradle head picture is reduced.

When the scheme is installed according to the panorama down and the cradle head up, the panorama of the camera can capture the panorama below, but the upper picture can be shielded by the cradle head structure, and the cradle head can see the upper picture but the lower picture can have dead angles limited by the cradle head structure. The camera is not far away from the lower part of the general installation environment, so that the advantage of preferentially guaranteeing the panoramic dead-angle-free picture is that although the picture below the camera cannot be covered by the tripod head, the panorama can ensure that the target is not lost, and the target below the camera can also generally lose some key identification information (details such as a face and a license plate) and the tripod head has great challenges for mechanical tracking when aiming at the target below the camera. The picture above the equipment relates to a target which is in a flying sense, on one hand, the probability of occurrence is lower, and in addition, any target entering the dead angle area can be in a panoramic non-dead angle area in advance, so that the detection of an event is not influenced. In general, this approach is that: an optimal balance scheme exists for a part of dead angle areas of the panorama and the tripod head.

The panorama and the cloud deck are respectively designed below and above, and the panorama and the cloud deck have the advantages that parallax does not exist in a horizontal visual angle, so that the requirements can be well met in calibration, but if the parallax in the vertical direction is too large, the problem that the calibration precision is difficult to meet the requirements is also caused. Our aim is to control the parallax within 10 degrees in the field of view (beyond 1 meter), so the distance between the panoramic imaging and the pan-tilt imaging module is controlled within 15 cm.

In addition, when the pan-tilt and panoramic camera are calibrated, errors and inaccuracy of initial zero-degree mechanical positioning of the pan-tilt are considered, and meanwhile the pan-tilt is required to accurately rotate to a target direction along with rotation control of the panorama, so that the pan-tilt and the panorama are required to be synchronized under the same initial coordinate system during installation.

The panoramic imaging system is used as a main coordinate system, the center of a tripod head picture coincides with a panoramic imaging center picture by controlling the rotation of the tripod head, the current tripod head rotation angle is recorded, and the current rotation state is used as an initial zero degree.

The specific calibration steps comprise:

assembling the cradle head and the panoramic camera;

collecting the picture of the cradle head and the picture of the panoramic camera through the PC section;

controlling the cradle head to rotate so that the picture center of the cradle head coincides with the picture center of the panoramic camera;

recording the rotation angle of the cradle head and storing the rotation angle into a camera;

with the initial angle calibrated, the cradle head rotates along with the picture center of the panoramic camera.

Based on the camera, the following specific problems can be effectively solved:

1. the working state of the camera can be observed at each angle of the equipment to ensure the awareness and privacy honour of the target;

2. the panoramic picture meeting the requirements can be captured even under the low illumination condition, and the capturing of the full-color picture is supported;

3. the hardware design can meet the condition that no dead angle exists, no event is lost, and the image capturing precision of a single event is guaranteed;

4. the multi-camera is convenient for remote cross-camera inspection and 3D roaming;

5. the hardware meets the spatial modeling of multiple cameras which can be updated in real time;

6. tracking and identifying multiple targets of the device without using a third-party server and crossing cameras;

7. multiple cameras can search for the complete flow across cameras for some event that has occurred.
