Panoramic monitoring device and monitoring system

Abstract

The invention discloses a panoramic monitoring device. The panoramic monitoring device comprises an outer cover, at least two camera lenses and a processor, wherein the at least two camera lenses and the processor are arranged in the outer cover. Each camera lens faces a fixed shooting direction so as to shoot an area image corresponding to the shooting direction. The camera shooting directions of the camera shooting lenses are different. The processor is electrically connected with the pick-up lenses so as to receive the area images of the pick-up lenses, and then the received area images are spliced into a panoramic image for monitoring. Therefore, the panoramic monitoring effect can be achieved under the condition that the shooting angle of each camera lens is not changed.

Description

Technical Field

[0001] The invention relates to a monitor, in particular to a panoramic monitoring device and a monitoring system. Background Art

[0002] If existing security cameras want to achieve 360-degree panoramic monitoring, they mostly use a fisheye lens with a lens swing mechanism. However, the lens swing mechanism not only increases the manufacturing cost, but the lens swing mechanism is also prone to failure after long-term operation, resulting in blind spots in monitoring and increased maintenance costs.

[0003] Furthermore, to use the results of fisheye lens shooting for security monitoring, it is necessary to use the fisheye lens to shoot regional images of different scenes in a space separately, then calibrate or expand each regional image, and finally combine all the calibrated or expanded regional images into a panoramic image. However, in the process of calibrating and combining regional images, some image information or resolution may be sacrificed, resulting in partial blurring of the panoramic image, which in turn causes the loss of monitoring information. Summary of the invention

[0004] To this end, one of the objects of the present invention is to provide a panoramic monitoring device and a monitoring system, thereby overcoming the problems caused by the need to set up a lens swing mechanism and the need to calibrate and join the images in the prior art.

Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Please refer to Figures 1 to 5 As shown, a panoramic monitoring device 1 provided by the present invention according to one embodiment can be installed on a support 2 (such as but not limited to a wall, a ceiling or Figure 4 The embodiment of the present invention is a bracket, and includes, for example but not limited to, a plurality of camera lenses 10, a fixing base 20, a housing 30, a processor 40 and an outer cover 50.

[0047] Each camera lens 10 includes an optical lens module composed of one or more lenses and an image sensor located on the imaging surface of the optical lens module. Each camera lens 10 is fixed on the fixing base 20 and is fixedly and individually oriented to a camera orientation to capture an image of a region corresponding to the camera orientation. The camera orientations of all camera lenses 10 are different from each other.

[0048] The camera lenses 10 include, for example but not limited to, a first main lens 10A, a second main lens 10B, a first auxiliary lens 10C, a second auxiliary lens 10D, a third auxiliary lens 10E and a fourth auxiliary lens 10F.

[0049] The camera orientation D1 of the first main lens 10A is opposite to the camera orientation D2 of the second main lens 10B. The camera orientations of all auxiliary lenses are different from each other, and are also different from the camera orientation D1 of the first main lens 10A and the camera orientation D2 of the second main lens 10B. Specifically, the camera orientation D3 of the first auxiliary lens 10C is opposite to the camera orientation D4 of the second auxiliary lens 10D, and the camera orientation D5 of the third auxiliary lens 10E is opposite to the camera orientation D6 of the fourth auxiliary lens 10F. The camera orientations D4 to D6 of the first auxiliary lens 10C to the fourth auxiliary lens 10F are, for example but not limited to, distributed at the same horizontal height, that is, on the same plane.

[0050] The field of view of each auxiliary lens partially overlaps with the field of view of the first main lens 10A or the field of view of the second main lens 10B. The field of view of two auxiliary lenses whose imaging directions are not opposite partially overlap.

[0051] In this embodiment, the field of view of the first main lens 10A is the same as the field of view of the second main lens 10B. However, the present invention is not limited to this embodiment. In other embodiments, the field of view of the first main lens 10A can also be changed to be different from the field of view of the second main lens 10B.

[0052] In this embodiment, the field of view of each auxiliary lens is smaller than the field of view of the first main lens 10A and the field of view of the second main lens 10B. However, the present invention is not limited to this embodiment. In other embodiments, the field of view of one or more auxiliary lenses can also be changed to be the same as or larger than the field of view of the first main lens 10A or the field of view of the second main lens 10B.

[0053] In the present embodiment, the field angle of the first master lens 10A and the field angle of the second master lens 10B are in the range of 100 to 150 degrees. However, the present invention is not limited to this embodiment.

[0054] In this embodiment, the viewing angle of each auxiliary lens is in the range of 90 degrees to 130 degrees. However, the present invention is not limited to this embodiment.

[0055] The camera lens 10 and the fixing seat 20 may be disposed in a housing 30 , and the housing 30 may expose each camera lens 10 .

[0056] The processor 40 is electrically connected to each camera lens 10 to receive the regional images captured by each camera lens 10 and stitch all the regional images received at the same time point into a panoramic image.

[0057] The outer cover 50 includes a light-permeable portion 51 and a main body 52. ​​The light-permeable portion 51 and the main body 52 can form a receiving space 53 together to accommodate the housing 30, the processor 40, and the camera lens 10 and the fixing seat 20 in the housing 30. The light-permeable portion 51 is a transparent or light-permeable protective cover, so each camera lens 10 can be seen through the light-permeable portion 51. The main body 52 can be connected or installed on the support 2, so the panoramic monitoring device 1 can be set anywhere for security monitoring.

[0058] The panoramic monitoring device 1 provided by the present invention can achieve the effect of panoramic monitoring without adjusting the shooting angle of the camera lens 10 during operation, and can even achieve the effect of monitoring without blind spots. In addition, since no additional mechanism for changing the shooting angle of the camera lens 10 is required, it can not only avoid the occurrence of shooting angle adjustment errors, but also simplify the mechanism complexity of the panoramic monitoring device 1, and can also reduce the manufacturing and maintenance costs.

[0059] Please refer to Figure 6 As shown, a monitoring system provided by the present invention according to an embodiment includes the panoramic monitoring device 1 and a monitoring server 3. The monitoring server 3 can be connected to the panoramic monitoring device 1 in communication to receive the panoramic image provided by the panoramic monitoring device 1, and then use an image analysis technology to identify the object appearing in the panoramic image and analyze the behavior of the object, so as to achieve the purpose of event analysis, that is, to interpret or even find out the violation, accident or abnormal event, so as to record and warn the violation, accident or abnormal event. The specific method of event analysis can refer to any feasible method or currently known method, which will not be repeated here.

[0060] Although the panoramic monitoring device 1 of the present invention is described by taking six camera lenses 10 as an example, in practice the number of camera lenses 10 may be changed to more than three or more than four.

[0061] Although the panoramic monitoring device 1 of the present invention is described by using two main lenses and four auxiliary lenses as an example, in fact, the number of main lenses and the number of auxiliary lenses can be adjusted according to needs. For example, one main lens is matched with two or three auxiliary lenses. Or, two main lenses are matched with one or two auxiliary lenses.

[0062] Furthermore, the imaging lens 10 of the panoramic monitoring device 1 of the present invention is not a fisheye lens.

[0063] See also Figure 7 As shown, a schematic diagram showing a panoramic monitoring device of another embodiment of the present invention is installed on a bracket, illustrating a state where there are two camera lenses 10. When there are two camera lenses 10, the two camera lenses 10 are correspondingly arranged, and each of the camera lenses 10 is a fisheye lens, and the viewing angle is at least 180 degrees, thereby constituting another implementation state.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
