The re-shooting of the panorama comprises the following types: shooting in the air, shooting by using ground conventional panoramic equipment, and shooting by using ground one-key automatic splicing panoramic equipment.
When unmanned aerial vehicle shoots, unmanned aerial vehicles of different types have different shooting flows, and the core flow is through the avigation planning function, provides accurate point position and the initial visual angle of aerial shooting for panorama shooting accurate the double photo, and concrete process is as shown in fig. 1, needs to judge different links, and concrete process is as follows:
step 1, unmanned aerial vehicle track manufacturing: the scheme uses a Dajiang unmanned aerial vehicle as shooting equipment, and the navigation point planning selects DJI Dajiang drawing or DJI GS PRO software, and the specific selection mode is determined according to the type of software supported by the unmanned aerial vehicle model: taking any point near the target point as a task starting point, and taking the target shooting point as a task end point to plan a waypoint flight task; the navigation belt starting point is not provided with any action; sequentially adding aircraft deflection angles to the terminal of the aerial belt, and taking a total of 2 actions; the shooting action is to check whether the shooting function of the camera is normal; the task ending action is set to not execute any action so as to reserve the current aerial position and the initial view angle of the unmanned aerial vehicle;
step 2, the unmanned aerial vehicle shoots a panoramic scheme: if the aerial photographing unmanned aerial vehicle supports a one-key panoramic function, entering a camera setting interface, modifying a photographing type into photographing panoramic, then manually clicking the photographing function, starting to execute an automatic panoramic photographing action by the unmanned aerial vehicle, and automatically splicing a complete panoramic photo; if the aerial unmanned aerial vehicle does not support the one-key panoramic function, shooting according to a standard panoramic shooting action: firstly, adjusting a lens to be downwards at 90 degrees vertically, respectively shooting 2 photos at vertical angles, and adjusting an initial angle restored by the unmanned aerial vehicle; then adjusting the lens to 60 degrees downwards, taking 6 series of pictures clockwise at intervals of 60 degrees, and adjusting the initial angle of the unmanned aerial vehicle for restoration; then adjusting the lens to 45 degrees downwards, taking 8 series of pictures clockwise at intervals of 45 degrees, and adjusting the initial angle of the unmanned aerial vehicle; then adjusting the lens to be horizontal, taking sequence pictures clockwise by taking 30 degrees as intervals, taking 12 total pictures, and adjusting the initial angle of the unmanned aerial vehicle for restoration; finally, adjusting the lens to be at an elevation angle of 30 degrees, taking sequence photos clockwise by taking 30 degrees as intervals, adjusting the initial angle restored by the unmanned aerial vehicle, and finishing panoramic shooting;
step 3, unmanned aerial vehicle accurately beats again: after the unmanned aerial vehicle equipment is started and take-off inspection is carried out, the manufactured waypoint flight task is selected, the task is executed, the space coordinates and the initial visual angle of the unmanned aerial vehicle after the task is executed are completely consistent with the state after the task is executed last time, then panoramic shooting is carried out according to the step 2, the consistency of each flight and the last shooting is ensured, and accurate re-shooting is realized.
The panoramic shooting equipment needs to use a steel tape and a compass for panoramic shooting, and long-term fixed marks such as steel nails, waterproof paint spraying and the like are needed to be made on the ground, the plane position of a shooting point position is accurately recorded, the compass is used for recording the initial angle of shooting, the steel tape is used for recording the height of shooting equipment (equipment such as a single-lens reflex camera) and the like, the concrete process is as shown in fig. 2, and follow-up repeated shooting is convenient:

step 2, adjusting an initial angle: setting an initial shooting angle by taking a compass as a standard, enabling a user to customize the initial shooting angle, recording a numerical value into the long-term fixed mark information by the angle, and then carrying out a complete panoramic shooting process according to the standard steps of shooting the panorama and the sequence;
step 3, panoramic manufacturing: the panoramic panorama stitching software is adopted to stitch the shot photos and make up for the days, and the stitching software can use PTGUI, PS and other software according to the habit of a photographer;
and 4, accurate re-shooting: erecting shooting equipment at a long-term fixed mark, adjusting equipment according to the equipment height and the initial shooting angle recorded by the point position, and shooting panoramic standard steps to perform panoramic accurate re-shooting.
The panoramic shooting needs to be carried out by the panoramic equipment with the ground and the automatic splicing by one key, and a steel tape and a compass are needed to be made on the ground for a long time to fix marks, such as steel nails, waterproof paint spraying and the like, and are used for accurately recording the plane position of shooting points, the compass is used for the characteristic angle of the panoramic camera, the steel tape is used for recording the height of the panoramic camera, the concrete process is as shown in fig. 3, and follow-up repeated shooting is convenient:
selecting the point: according to shooting needs, shooting points are selected, long-term fixed marks are distributed on the ground, the mark numbers are recorded, panoramic shooting equipment is erected, and the vertical height from the ground to the bottom of the shooting equipment is measured and recorded.
Step 2, adjusting an initial angle: setting the angle of panoramic equipment by taking a compass as a standard, enabling a user to customize an initial shooting angle, recording a numerical value of the angle into the long-term fixed mark information, and then carrying out a panoramic one-key shooting process to obtain a panoramic picture;
and 3, accurate re-shooting: when the panoramic shooting device is used for shooting again, shooting equipment is erected at a long-term fixed mark, and the panoramic shooting device is adjusted according to the equipment height recorded by the point location and the angle of the equipment during initial shooting, so that the panoramic precise repeated shooting is realized.
