A safety-critical control system and method with train-time calibration of object detection. A controller calibrates prediction by a deep neural network. The train-time calibration includes a multi-class confidence calibration, and a bounding box localization calibration. The controller outputs a calibrated image with the object bounding box, the corresponding class label, and a respective confidence score. The confidence score is a probability associated with the predicted class label. The multi-class confidence calibration is determined as a difference between a fused mean confidence and a certainty with accuracy. The fused mean confidence is between a mean logits-based class-wise confidence and class wise certainty. The controller determines the localization calibration by determining a deviation between a predicted mean bounding box overlap and a predictive certainty of the bounding box.
