Planecell: Representing Structural Space with Plane Elements
Bibliographic record
Abstract
Reconstruction based on the stereo camera has received considerable attention recently, but two particular challenges still remain. The first concerns the need to present and compress data in an effective way, and the second is to maintain as much of the available information as possible while ensuring sufficient accuracy. To overcome these issues, we propose a new 3D representation method, namely, planecell, that extracts planarity from the depth-assisted image segmentation and then directly projects these depth planes into the 3D world. The proposed method demonstrates its advancement especially dealing with large-scale structural environment, such as autonomous driving scene. The reconstruction result of our method achieves equal accuracy compared to dense point clouds and compresses the output file 200 times. To further obtain global surfaces, an energy function formulated from Conditional Random Field that generalizes the planar relationships is maximized. We evaluate our method with reconstruction baselines on the KITTI outdoor scene dataset, and the results indicate the superiorities compared to other 3D space representation methods in accuracy, memory requirements and the scope of applications.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
