What are the precautions for panoramic camera when shooting?

Equipment stability : Make sure that the panoramic camera is installed on a stable tripod or other supporting equipment and will not shake or move during shooting. If a tripod is used, its three legs should be fully extended and adjusted to the same height to ensure the level of the PTZ. After the tripod is erected, the level of the PTZ shall be checked to ensure that the bubbles, the center point and the outer circle are mutually contained and centered.

Lens cleaning : Clean the lens carefully before shooting to prevent dust, fingerprints and other stains on the lens from affecting the image quality.

Focus setting : Focus accurately in advance, and try not to change the focus position during shooting. If a panoramic camera with auto focus function is used, ensure that its focus mode and parameter settings are correct; If you focus manually, you need to adjust the focus precisely to ensure that the entire scene can be imaged clearly.

Fixed parameters : After determining the appropriate exposure parameters (aperture, shutter speed, sensitivity, etc.) and white balance settings, keep these parameters unchanged throughout the shooting process. Otherwise, parameter differences between different photos may lead to mismatches in color, brightness and other aspects during later splicing.

View locking : If the lens of the panoramic camera can rotate or adjust the angle of view, the angle of view should be locked before starting shooting to prevent accidental rotation of the lens during shooting and affect the consistency of the picture.

Uniform illumination : Try to choose an environment with uniform light for shooting to avoid strong light dark contrast. If there are too bright or too dark areas in the scene, you can consider using light compensation equipment or adjusting the shooting angle to improve the light conditions. For example, when shooting indoors, you can turn on indoor lights or use reflectors; When shooting outdoors, avoid shooting in direct sunlight or places with heavy shadows.

Avoid backlighting : Backlighting is a taboo in panoramic photography, which may lead to unclear subject or too bright background. If you can't avoid the backlight scene, you can try shooting in the weak light period, or use accessories such as a mask to reduce the impact of backlight.

Light conditions ：

Spatial scope : Select an open space for shooting, so as to capture the panoramic picture completely. Avoid shooting in narrow, crowded or obstructed places, otherwise the shooting effect may be affected or the picture splicing may be incomplete. At the same time, attention should be paid to the distance between the objects in the shooting scene and the lens. It is generally recommended that the distance should be more than 1.5 meters from the lens to avoid the splicing defects of objects under different camera shooting angles.

Background selection : Select a simple background without obvious features or textures as the splicing area, which can reduce the difficulty and defects of later splicing. Avoid too complex patterns, characters or objects with large color changes in the splicing area.

Shooting sequence : Shoot in a certain order, such as rotating clockwise or counterclockwise, to ensure that the pictures from each angle can be completely recorded. Develop a fixed shooting habit to avoid missing shots from a certain angle.

Overlapping area : There should be enough overlap between adjacent photos. It is generally recommended that the overlap rate should be between 30% - 50%, which is conducive to the later image mosaic processing. If there is too little overlap, the splicing may fail; If there are too many overlapping parts, the workload of post processing will increase.

shooting speed : The action should be steady and slow during shooting, and avoid moving or shaking the camera quickly. If you use an auto rotating panoramic PTZ, you should set a proper rotation speed to ensure that the shooting interval of each photo is even.

Avoid interference : During shooting, avoid your own shadow, the shadow of the tripod or the shadow of other objects entering the picture, and also avoid the camera and the tripod projecting onto reflective objects such as mirror glass.

Mobile transaction processing : If there are moving people, cars, animals, etc. in the shooting scene, try to avoid them from appearing in the picture, or ensure that they do not have obvious position changes in the pictures from different angles, otherwise, "ghost" and other problems will occur during later splicing.

Data backup : After shooting, back up photos or video data to multiple storage devices in time to prevent data loss. Before post-processing, it is better to back up the original data so that it can be restored to the original state in case of problems during processing.

Format selection : Understand the file formats supported by different panoramic cameras and the formats supported by post-processing software, and select the appropriate file format for shooting and saving. Common panorama image formats include JPEG, PNG, TIFF, etc. Panorama video formats include MP4, AVI, MOV, etc.
