Positioning method and device and electronic equipment

The embodiment of the invention provides a positioning method and device and electronic equipment, and relates to the technical field of image processing. Acquiring a to-be-detected image about the to-be-detected object acquired by image acquisition equipment; performing object detection on the to-be-detected image to obtain an image center point of the detected target object; mapping the target three-dimensional point set of the to-be-detected object to the to-be-detected image by using a preset conversion relation; determining an initial mapping point corresponding to the image center point in each mapping point obtained by mapping the target three-dimensional point set, and determining a target mapping point corresponding to the image center point based on the initial mapping point; and positioning a target center point of the target object in the to-be-detected object based on the target mapping point. Compared with the prior art, by applying the scheme provided by the embodiment of the invention, the pos
