Description

Technical Field

[0001] The present invention relates to the technical field of target detection, and in particular to an omnidirectional detection airborne optoelectronic device. Background Art

[0002] Drones have been widely used in many fields such as military reconnaissance, environmental monitoring, disaster relief, logistics and distribution. In these application scenarios, drones need to obtain real-time and accurate information about the surrounding environment to achieve functions such as obstacle avoidance, target tracking, and terrain mapping.

[0003] At present, unmanned aerial vehicle-mounted optoelectronic detection equipment must rely on motors to drive the optical payload to rotate in order to achieve omnidirectional detection.

[0004] Due to the limited field of view of the camera, only targets within the camera's field of view can be detected at the same time. When the target appears outside the field of view, the motor needs to be rotated to make the target appear in the camera's field of view. If the motor rotates too fast, the image will be blurred and smeared. If it rotates too slowly, the target may be lost, which is inconvenient to use. Summary of the invention

[0005] The purpose of the present invention is to provide an omnidirectional detection airborne optoelectronic device, which aims to solve the technical problem that only targets within the camera's field of view can be detected at the same time. When the target appears outside the field of view, the motor needs to be rotated to make the target appear in the camera's field of view. If the motor rotates too fast, the image will be blurred and smeared. If it rotates too slowly, the target may be lost, which is inconvenient to use.

[0006] To achieve the above-mentioned purpose, the present invention adopts an omnidirectional detection airborne optoelectronic device, comprising a mounting seat, a UAV connection seat, a plurality of optoelectronic cameras and a plurality of mounting components, wherein the mounting seat is connected to the UAV connection seat, the plurality of optoelectronic cameras are respectively located on the outside of the mounting seat, and each group of the mounting components is respectively connected to the mounting seat and the corresponding optoelectronic camera;

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] See also Figures 1 to 8 The present invention provides an omnidirectional detection airborne optoelectronic device, comprising a mounting seat 101, a drone connection seat 102, a plurality of optoelectronic cameras 103 and a plurality of mounting components, wherein the mounting seat 101 is connected to the drone connection seat 102, a plurality of optoelectronic cameras 103 are respectively located on the outside of the mounting seat 101, and each group of the mounting components is respectively connected to the mounting seat 101 and the corresponding optoelectronic camera 103;

[0027] The installation assembly includes a plug-in column 104, a holding spring 105, a toggle block 106, a plug-in rod 107, a first magnetic block 108 and a second magnetic block 109. The plug-in column 104 is fixedly connected to the photoelectric camera 103 and is located on the outside of the photoelectric camera 103. The mounting seat 101 has a plug-in slot 110 and a limiting slot 111. The plug-in column 104 has a fixing hole 112, and the first magnetic block 108 is fixedly arranged in the fixing hole 112. The toggle block 106 is movably connected to the mounting seat 101 and is respectively located in the limiting slot 111. The two ends of the holding spring 105 are respectively fixedly connected to the mounting seat 101 and the toggle block 106. The plug-in rod 107 is fixedly connected to the toggle block 106 and is located in the limiting slot 111. The second magnetic block 109 is fixedly connected to the plug-in rod 107 and is magnetically attracted to the first magnetic block 108.

[0028] In this embodiment, when in use, a plurality of the photoelectric cameras 103 are installed at corresponding positions on the mounting seat 101, wherein the plug-in column 104 at the end of the photoelectric camera 103 is inserted into the plug-in slot 110 of the mounting seat 101, and at the same time, the toggle block 106 is toggled on the mounting seat 101, and the toggle block 106 drives the plug-in rod 107 to enter the limiting slot 111, and the toggle block 106 squeezes the holding spring 105 in the limiting slot 111, and continues to push the plug-in column 104 until the plug-in column 104 enters the mounting seat 101. In the plug-in slot 110 of the seat 101, as the toggle block 106 is released, the resisting spring 105 will resume its stretching and drive the plug-in rod 107 to enter the fixing hole 112 of the plug-in column 104. At the same time, the second magnetic block 109 at the end of the plug-in rod 107 will be magnetically attracted to the first magnetic block 108 in the fixing hole 112, so that the plug-in rod 107 is not easy to be separated from the fixing hole 112, thereby installing the photoelectric camera 103 on the mounting seat 101; multiple photoelectric cameras 103 cover 360° horizontally and 90° vertically. Range, considering the factor of image distortion, the optoelectronic camera 103 with a fixed focus of 95° horizontal and 53.4° vertical field of view is selected. A total of 6 optoelectronic cameras 103 are required, which can cover the hemispherical space of 360° horizontally and 90° vertically. The edge distortion can be cut off by the image processing module. The installation of the optoelectronic camera 103 needs to ensure that the angle error between the optical axis and the optical axis is less than 0.1°; the position of the target can be detected by the optoelectronic camera 103. In addition, the position of the target in the field of view of the optoelectronic camera 103 is calculated. The optical axis of each optoelectronic camera 103 The azimuth and pitch angles have been determined. Assuming that the azimuth angle of the optical axis of the photoelectric camera 103i is α, and the pitch angle is β, the imaging position of the target at the photoelectric camera 103i is horizontal pixel x and vertical pixel y away from the center point of the photoelectric camera 103. Assuming that the resolution of the photoelectric camera 103 is 1920*1080, the azimuth angle of the target is α+x / 1920*95, and the pitch angle is β+y / 1080*53.4.
