DETAILED DESCRIPTION OF THE EMBODIMENTS
[0012] As Figure 1 shown, the present invention provides a portable binocular vision cloud information data acquisition device, including a pair of binocular acquisition cameras, a binocular vision optical axis adjustment system, a fisheye panoramic camera, and a detachable two-dimensional motion platform. The binocular vision optical axis adjustment system is movably connected and installed on the detachable two-dimensional motion platform, the fisheye panoramic camera is fixedly connected and installed on the detachable two-dimensional motion platform, the binocular acquisition cameras are fixedly connected and installed on the binocular vision optical axis adjustment system, and the pair of binocular acquisition cameras are symmetrically arranged on both sides of the fisheye panoramic camera, and the three are arranged in a straight line. It also includes a platform support frame, and the detachable two-dimensional motion platform is detachably fixed on the platform support frame. The binocular vision optical axis adjustment system includes an adjustment component, an azimuth component, and a pitching component. The adjustment component includes a driving mechanism (motor) and a detachable support rod. A pair of binocular acquisition cameras are fixedly installed at both ends of the detachable support rod through adjustment seats. The detachable support rod is movably connected to the azimuth component and the pitching component. The fisheye panoramic camera is movably connected to the azimuth component and the pitching component. The driving mechanism, that is, the motor, is movably connected to the azimuth component and the pitching component. The azimuth component includes a slip ring. The pitching component includes a limiting structure 。
[0013] A pair of binocular acquisition cameras, a binocular vision optical axis adjustment system, a fisheye panoramic camera, and a detachable two-dimensional motion platform are all connected and communicate with a control computer. The control computer is used to control the binocular vision optical axis adjustment system to adjust the position and angle of the pair of binocular acquisition cameras and the fisheye panoramic camera so that they meet the shooting and acquisition angle requirements, and is used to control the shooting of the pair of binocular acquisition cameras and the fisheye panoramic camera to make them shoot image data that meets the requirements, and store the image data.
[0014] Specifically, the binocular acquisition cameras use the binocular vision principle to collect the cloud images in the external field, that is, they are used to collect cloud data; the fisheye panoramic camera is used to collect panoramic sky images and collect the cloud images in the area where it is located, which is convenient for subsequent production of all-sky cloud images; the detachable two-dimensional motion platform is used to execute the adjustment of the image acquisition angle of the binocular cameras, specifically to provide a rotation angle for the binocular cameras, which is convenient for the binocular cameras to capture each cloud image in the panoramic camera for subsequent analysis; the platform support frame is used to provide a stable support for the platform in the external field, ensure the level of the platform, and facilitate the collection work.
[0015] When using the portable binocular vision cloud information data acquisition device of the present invention, after the visible light panoramic camera and the binocular stereo vision measurement camera group are fixed on the mounting bracket, they are not moved unless necessary. The parameter calibration of the three cameras is completed through the multi-camera stereo calibration module of the software, and the calibrated information is stored in the form of software configuration items. Subsequently, during the operation of the software, there is no need to perform camera calibration again.
