Opta applies for a patent related to application template posture construction, introducing a rotation compensation mechanism to eliminate deviations and reduce azimuth deviation.

On April 3, the National Intellectual Property Administration’s information shows that Guangdong Optex Technologies Co., Ltd. has filed a patent titled “Template Pose Feature Construction Method, System, and Computer-Readable Storage Medium.” The application publication number is CN121767413A, the application number is CN202511987637.9, the application publication date is March 31, 2026, the application date is December 25, 2025. The inventors are Zhong Hongyan, Pan Wei, Cao Ling, Huang Wei, Tang Yaru, and Lu Shenglin. The patent agent is Beijing Xin Hao Lian De Patent Agency (General Partnership), and the patent agent is Mai Jianwei. The classification numbers are G06T7/33, G06T5/50, and G06T3/60.

The patent abstract indicates that this invention relates to the field of computer vision and image matching technology, and discloses a template pose feature construction method and system. The method includes: constructing an image pyramid containing multiple resolution levels based on template images; extracting feature points of the first-layer images and calculating an initial orientation encoding value for each feature point; for each combination of parameters within a preset pose parameter range, calculating an orientation bias correction amount used to eliminate interpolation error, combining the initial orientation encoding value, the rotation angle, and the orientation bias correction amount into a compensated orientation encoding value, and performing a geometric transformation on the feature point coordinates according to the parameter combinations, where the parameter combinations include a rotation angle and a scale factor; generating a multi-pose feature model based on the transformed coordinates and the compensated orientation encoding value. By introducing an adaptive rotation compensation mechanism, the invention effectively eliminates systematic bias introduced by linear interpolation and significantly reduces azimuth-angle deviation.
