Spatial positioning method for physical, chemical and biological experiment operation area based on set condition target detection

The invention discloses a physical, chemical and biological experiment operation area space positioning method based on set condition target detection, and relates to the field of set condition target detection. YOLOv5 is adopted to detect a characteristic target, namely, different picture shapes and colors of four vertexes of an operation area, when one point or two points of the operation area appear in a camera picture, the point or the two points can be quickly identified through a target detection algorithm, the corresponding point can be quickly found through a corresponding rule, and finally, the four vertexes corresponding to the operation area are found out. According to the camera angle rotation algorithm when the preset point is matched with the gravity center of the four vertexes of the subsequent operation area, the coordinate value of the preset point relative to the video playing page and the coordinate value of the gravity center of the operation area are obtained, and the width/2 of the playi
