Abstract
Power inspection in low-illuminance environments is of great significance for ensuring the all-weather stable operation of the power system. However, low visibility at night seriously interferes with the detection performance of small-sized power devices. In response to the issue, we propose a small object real-time detection method for power line inspection in low-illuminance environments. We design an adaptive transformer-ISP (ATISP) module, in which the optimal parameter regression module generates hyperparameters by sensing input image features to guide the image signal processors (ISPs) to perform image enhancement. With the advantage of ISPs, the ATISP has the advantages of fast inference speed and less training cost. Furthermore, the optimal parameter regression module extracts local features and long-distance dependencies through CNN and Transformer to be able to more fully perceive the input image, so that the generated hyperparameters better enhance image defects. In addition, we use lightweight neural network MobileNetv3 to improve YOLOv7, so that the algorithm maintains excellent small object detection performance while significantly increasing the detection speed. Moreover, the integrated model optimisation uses only the object detection loss functions, which allows ATISP to perform image enhancement just according to the object detection needs, improving small object detection effect and shortening the inference time of ATISP. In extensive experiments, compared with 9 state-of-the-art object detection algorithms, our algorithm has the best small-scale insulator faults detection precision (mAP:75.38 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$\%$</tex-math></inline-formula> ) in our DIFE, best small object detection precision (mAP:56.31 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$\%$</tex-math></inline-formula> ) in public dataset Exdark, and faster detection speed (FPS:98.81 and 97.53), which prove our method can achieve fast and accurate low-illuminance insulators detection.

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 it
