Abstract

fetched live from OpenAlex

For robotic surveillance systems, real-time knowledge of the motion of objects in the surrounding environment allows greater autonomy and interactivity. In some applications, orientation is of just as much interest as the position of an object. This paper presents a novel 3D model based method for tracking the full 3D pose of a rigid body. The proposed method projects a texture-mapped model of the target object back onto the camera's image plane at the target's current predicted pose. Optical-flow is used to correct the error between the predicted pose and the real pose. Finally, the pose in the next time-step is estimated using a motion predictor such as a Kalman filter (KF). The proposed tracking algorithm was tested using both synthetic and real video sequences of a 50/spl times/50/spl times/50 mm textured cube. This cube's pose was successfully tracked to within 2.5 mm positionally and 0.6/spl deg/ angularly. The cube was approximately 600-840 mm away from the camera.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
