Method for judging dead bodies of nematodes

The invention discloses a nematode dead body judgment method, which comprises the following steps: a model training stage: continuously shooting, marking and storing in a yolk format, training a YOLOv5 nematode automatic identification model based on deep learning, and outputting an optimal weight model; in combination with a DeepSort algorithm, dynamic tracking of the nematodes is realized on the basis of the optimal weight model; a dynamic identification stage: selecting the nematodes with the largest number as a reference map; the specific ID of the nematode loaded in the reference map is compared with the corresponding nematode in other maps in sequence, if the similarity of histograms of the nematode loaded in the reference map and the corresponding nematode loaded in the other maps is smaller than 0.9, or the difference of binary pixel points exceeds 50%, the nematode is a living body, the comparison of the ID nematode is terminated, and otherwise, the comparison of the ID nematode corresponding to the
