ChangeLog

9.1.0（2026.8.11）​

🐞 Bug fixes​

  • Fixed an issue where the lower-layer video failed to render at overlapping regions during video cropping processing.
  • Optimized the intrinsic parameter calibration algorithm for bullet cameras.
  • Fixed logical errors in the extrinsic parameter update point calculation and added rule validation checks.
  • Fixed the issue where distortion correction parameters for fisheye camera projection stretching did not take effect.

9.0.0（2026.7.31）​

✨ Features and improvements​

  • Camera management: Register and maintain fixed, fisheye, and other camera types; view calibration status.
  • Group configuration: Maintain multi-level groups by business area or spatial location and assign cameras to groups.
  • Scene configuration: Load and save one global 3D model scene for reuse in calibration and video processing.
  • Fixed-camera calibration: Correct distortion, calculate intrinsic and extrinsic parameters, match points, fine-tune, and save results.
  • Fisheye calibration: Correct fisheye distortion, reuse parameters, configure a center point, and calibrate points on multiple faces.
  • Video processing: Control camera visibility, apply color matching, and configure crop regions for accurate placement in the scene.
