This invention relates to the field of computer vision and image processing technology, and discloses a method, apparatus, device, and storage medium for calculating camera aiming points. The method improves the calculation accuracy and robustness of the camera's main optical axis aiming points by introducing a distance-based inverse weighted fusion mechanism, and can adaptively suppress errors caused by lens distortion. Specifically, the method dynamically adjusts the weight of each marker aiming point in the fusion result by calculating the distance from the geometric center coordinates of the marker to the center coordinates of the image, so that the marker aiming points closer to the main optical axis contribute more to the final result. Through weight adjustment, even in extreme cases where the camera is shooting at close range with a skewed viewing angle or where some markers obscure the image and cause severe distortion, it can still output smooth and near-true aiming point coordinates, effectively avoiding severe aiming point jitter caused by individual marker recognition jumps, and eliminating the need for complex lens intrinsic parameter calibration and distortion correction calculations, thus simplifying the system deployment process.

This invention belongs to the field of inspection robot technology and discloses an intelligent capture and correction system for smart inspection robots.

The system adopts an adaptive PID and model predictive feedforward composite control algorithm, which tunes the control parameters in real time based on the gyroscope angular velocity change rate. The feedforward term can predict the attitude deviation trend in advance and offset dynamic interferences such as motion inertia, road bumps, and wind resistance. At the same time, an overshoot suppression factor is added to avoid severe gimbal jitter.
