Problems solved by technology

[0003] Target detection refers to the use of computer vision technology to accurately detect the required target from the image. However, the current method of target detection in the field of computer vision mainly has the following problems: 1. When performing target detection on multiple frames of video frames, often The occurrence of object detection false positives, which means that current convolutional neural networks have difficulty suppressing false positives from poorly recognized locations
Specifically, take the situation of high-altitude parabolic or high-altitude falling objects as an example: take a bag of 250 grams of clothes falling freely fro

Example Embodiment

[0047] Next, the technical solutions in the embodiments of the present invention will be apparent from the embodiment of the present invention, and it is clearly described, and it is understood that the described embodiments are merely embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art are in the range of the invention.

[0048] This program provides a target detection, trajectory tracking method, model, and electronic device. The target detection model has a new model architecture, and is fully trained through training samples, which can be precisely from the input detection video. Small objectives are detected, in some embodiments, the motion trajectory of specific targets can be tracked to detect dynamic processes of dynamic targets. Specifically, the deep learning-based target detection model adds a cavity encoding module after the backbone net...
