技术领域Technical field

多目摄像机是较为常用的摄像设备，多目摄像机的机体上搭载有多个镜头，多个镜头沿着机体的圆周方向分布。目前的多目摄像机的多个镜头通常固定在基座上，进而进行各个角度方向的拍摄。多个镜头所拍摄的图像能合成多目摄像机的全景图像。A multi-eye camera is a relatively common imaging device, and a multi-camera has a plurality of lenses mounted on the body, and a plurality of lenses are distributed along the circumferential direction of the body. The multiple lenses of the current multi-camera are usually fixed on the pedestal for shooting in various angular directions. The images captured by multiple lenses can be combined into a panoramic image of a multi-camera.
在具体的拍摄过程中，有时拍摄环境较暗，这需要为多目摄像机配置补光设备。目前的多目摄像机的补光灯一般设置在镜头的两侧或一侧，补光灯与镜头安装在同一水平面。但是多目摄像机安装完成后多个镜头的拍摄角度预先设定，因此用户无法根据自己感兴趣的场景进行拍摄角度的调整。基于此，能够对镜头位置可调的多目摄像及应运而生，此种多目摄像机能够实现镜头拍摄角度的灵活调整。但是，现在的多目摄像机的补光灯则无法满足镜头可调的多目摄像机的补光要求，往往会出现近处光强较强而远处光强较弱的情况，进而影响镜头所拍摄图像的质量。In the specific shooting process, sometimes the shooting environment is dark, which requires the filling device for the multi-camera. The current multi-camera fill light is generally placed on either side or side of the lens, and the fill light is mounted on the same level as the lens. However, after the multi-camera camera is installed, the shooting angles of the multiple lenses are preset, so the user cannot adjust the shooting angle according to the scene of interest. Based on this, it is possible to multi-camera camera with adjustable lens position, which can realize flexible adjustment of lens shooting angle. However, the current multi-camera fill light can not meet the fill-in requirements of the multi-camera camera with adjustable lens, and there is often a situation where the near-field light intensity is strong and the far-field light intensity is weak, which affects the lens. The quality of the image.

It is apparent that the described embodiments are only a part of the embodiments of the present application, and not all of them.

以下结合附图，详细说明本申请各个实施例提供的技术方案。The technical solutions provided by the various embodiments of the present application are described in detail below with reference to the accompanying drawings.
请参考图1-13，本申请实施例公开一种多目摄像机的补光装置100，所公开的补光装置100包括多个补光灯110和用于安装在多目摄像机的摄像主机200上的环状灯座130。Referring to FIG. 1-13, an embodiment of the present application discloses a light-filling device 100 for a multi-view camera. The light-filling device 100 includes a plurality of fill light lamps 110 and an image pickup host 200 for mounting on a multi-view camera. The annular lamp holder 130.
环状灯座130为多个补光灯110的安装基础，安装有多个补光灯110的环状灯座130套设在多目摄像机的多个镜头230之外，进而为多个镜头230实施补光。多个补光灯110可以沿环状灯座130的圆周方向分散布置。具体的，环状灯座130可以具有呈环状的倾斜安装面，多个补光灯110沿着倾斜安装面的圆周方向分散布置。The annular socket 130 is a mounting base of the plurality of fill lamps 110, and the annular socket 130 on which the plurality of fill lamps 110 are mounted is sleeved outside the plurality of lenses 230 of the multi-camera, and further is a plurality of lenses 230. Implement fill light. The plurality of fill lamps 110 may be dispersedly arranged along the circumferential direction of the annular socket 130. Specifically, the annular socket 130 may have an inclined mounting surface in a ring shape, and the plurality of fill lamps 110 are dispersedly arranged along the circumferential direction of the inclined mounting surface.
环状灯座130所在的平面通常与多目摄像机的安装面相平行，而多目摄像机的安装面通常与环状灯座130的轴向相垂直。本实施例中，倾斜安装面相对于环状灯座130所在的平面倾斜布置，环状灯座130所在的平面与环状灯座130的轴线相垂直。一种具体的安装场景中，多目摄像机安装后，环状灯座130的轴线沿竖直方向延伸，环状灯座130所在的平面处于水平面内。The plane in which the annular socket 130 is located is generally parallel to the mounting surface of the multi-camera, and the mounting surface of the multi-camera is generally perpendicular to the axial direction of the annular socket 130. In this embodiment, the inclined mounting surface is disposed obliquely with respect to the plane in which the annular socket 130 is located, and the plane of the annular socket 130 is perpendicular to the axis of the annular socket 130. In a specific installation scenario, after the multi-view camera is installed, the axis of the annular socket 130 extends in a vertical direction, and the plane in which the annular socket 130 is located is in a horizontal plane.
需要说明的是，倾斜安装面为补光灯110提供安装基础，使得补光灯110也倾斜投射光线，进而能更好地使得补光灯110能够为镜头的拍摄实施补光，补光装置100涵盖镜头位置调整可视视场的所有区域。因此，倾斜安装面向着多目摄像机的多个镜头的外侧倾斜。请再次参考图5，一种具体的实施方式中，环状灯座130所在的平面与倾斜安装面之间的夹角A可以为20-40°。经过验证，夹角A为20-40°时，补光灯110的光线能够有足够的光线向镜头230的外侧投射，同时又能保证多个补光灯110较容易在多目摄像机的拍摄侧拼接成全景补光区域。具体的，两者之间的夹角可以为32°。It should be noted that the inclined mounting surface provides a mounting base for the fill light 110, so that the fill light 110 also obliquely projects light, thereby better enabling the fill light 110 to fill the lens, and the light filling device 100 Covers the lens position to adjust all areas of the visual field of view. Therefore, the tilt mounting is inclined toward the outer side of the plurality of lenses of the multi-eye camera. Referring again to FIG. 5, in a specific embodiment, the angle A between the plane in which the annular socket 130 is located and the inclined mounting surface may be 20-40 degrees. It has been verified that when the angle A is 20-40°, the light of the fill light 110 can have enough light to be projected to the outside of the lens 230, and at the same time, it is ensured that the plurality of fill lamps 110 are easier to be on the shooting side of the multi-view camera. Stitch into a panoramic fill area. Specifically, the angle between the two may be 32°.
补光灯110包括发光体116和罩设在发光体116上的偏配光元件112，偏配光元件112可以是偏配光透镜、偏配光反射器等实现偏配光的光学元件。旋转对称光学元件(例如旋转对称透镜)能够对光线实施配光，发光体的光轴与旋转对称光学元件的峰值光强重合，进而较容易造成补光的远处与近处的亮度对比较大，影响镜头的拍摄效果。相比于旋转对称光学元件(例如旋转对称透镜)而言，偏配光元件112用于将发光体116发出的光线向着远离环状灯座130的外侧射出，进而能够使得发光体116发出的光线更多的投向远处。偏配光元件112的峰值光强与发光体116的光轴之间呈一定的夹角(非重合)，多个补光灯110拼接后的峰值光强与多目摄像机的轴线之间具有较大的夹角，进而使得更多的光投射在距镜头较远处，实现远距离更好的补光，提高远处物体表面的亮度，同时还能降低近处的补光强度，从而能够减低图像近处的亮度，最终能够提升镜头所获取图像的质量。The fill light 110 includes an illuminator 116 and a bias light element 112 that is disposed on the illuminator 116. The bias light element 112 may be an optical element that realizes partial light distribution such as a bias light lens or a bias light reflector. A rotationally symmetric optical element (such as a rotationally symmetric lens) is capable of modulating light, and the optical axis of the illuminant coincides with the peak intensity of the rotationally symmetric optical element, thereby making it easier to cause a large contrast between the distant and near portions of the fill light. , affecting the shooting effect of the lens. Compared with a rotationally symmetric optical element (for example, a rotationally symmetric lens), the biasing light element 112 is configured to emit light emitted from the illuminator 116 toward the outside of the annular socket 130, thereby enabling the illuminating body 116 to emit light. More investment in the distance. The peak light intensity of the partial light distribution element 112 and the optical axis of the illuminator 116 have a certain angle (non-coincidence), and the peak light intensity after merging the plurality of fill light lamps 110 is compared with the axis of the multi-eye camera. The large angle, which causes more light to be projected farther from the lens, achieves better fill light at a long distance, improves the brightness of the surface of distant objects, and reduces the fill light intensity in the vicinity, thereby reducing The brightness of the image near the end can ultimately improve the quality of the image acquired by the lens.
