Multimodal Remote Sensing Classification Algorithms for Vehicle-Road-Cloud Integration
Bibliographic record
Abstract
The deep integration of intelligent driving systems with remote sensing technology fundamentally leverages the macro-environmental perception capabilities of remote sensing data to compensate for the limitations of onboard sensors such as cameras and LiDAR in terms of field of view, environmental adaptability, and scene comprehension. This enables the construction of a multi-dimensional collaborative perception system encompassing vehicles, roads, and cloud infrastructure. However, existing approaches face challenges when processing multi-source remote sensing data (such as hyperspectral images and LiDAR), including imbalanced complementary feature extraction and spatial feature redundancy due to significant differences in data dimensionality. To address this, this paper proposes an asymmetric Class Enhanced guided Elevation and Spectral Encoding network. First, overlapping grouping by spectral channel is employed to mitigate feature extraction imbalance caused by large data dimensionality differences. Subsequently, a Class Attribute Enhanced Tokenization module focuses on spectral channel groups and elevation features within image patches that best represent class attributes. Complementary semantic features are then fused through cross-modal attention within the encoder. Concurrently, the cross-spectral attention-based encoding approach aggregates spectral features across different spectral channel groups, avoiding redundant spatial feature extraction. Finally, experiments across two joint datasets demonstrate that this approach achieves significantly higher overall accuracy compared to existing classification algorithms. It effectively extends the environmental perception range of vehicle-road coordination systems, offering novel insights for multi-source remote sensing data fusion in intelligent driving.

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.
