1. In-camera splicing: the image splicing is completed within the camera, so there is no need to calculate the splicing in the phone, which has relatively low requirements for the phone's performance;

2. Image quality: professional image performance debugging to ensure the overall image brightness, white balance, saturation, contrast and other performance and noise effect under low illumination;

3. Image stitching advantages: stitching algorithm with independent intellectual property rights and mature mass production tools:

4. Image and optical correction: mature image and optical correction algorithms and mass production tools ensure perfect image quality;
