Problems solved by technology

[0003] There are two types of detection methods in the existing technology, one is pure deep learning target detection and target segmentation, this method cannot obtain the precise characteristic parameters of the target, cannot detect large-resolution images in real time, and there is a large-resolution training model Problems that consume time and a lot of computing power, that is, problems that cannot meet the real-time detection requirements of customers; the other type is traditional machine learning detection, which cannot be accurately classified, requires an expert mode to adjust parameters, and the accuracy rate cannot reach 99% stably recognition rate above
