The invention discloses a method and device for detecting the position of a human body in an image, and relates to the field of artificial intelligence. The method comprises the steps: determining theposition coordinates of a human body frame corresponding to a human body image from a to-be-detected image comprising the human body image; performing multiple regression calculations on the positioncoordinates of the human body frame corresponding to the human body image in the to-be-detected image by using a frame regression loss function based on the evaluation threshold vector obtained by learning to obtain a regression offset parameter set corresponding to the evaluation threshold vector; performing multi-dimensional contrastive analysis on each group of regression offset parameters inthe regression offset parameter group set, and determining an optimal regression offset parameter group; and generating a final position coordinate of the human body frame based on the optimal regression offset parameter set. According to the scheme, the accuracy of human body frame position coordinate detection is improved, and the detection result of the human body image is further more accurate.
Description
technical field [0001] The embodiments of the present application relate to the field of computer technology, specifically to the field of artificial intelligence, and in particular to a method and device for detecting the position of a human body in an image. Background technique [0002] With the continuous development of the Internet and artificial intelligence technology, more and more fields have begun to involve automatic calculation and analysis, among which the human body detection function of monitoring security is one of the important scenarios. [0003] The body frame results obtained by human body detection in the common security video field sometimes have a certain deviation from the actual target. Although there is some overlap with the actual target, it may not completely cover the entire human body. When using this kind of inaccurate human body detection frame for subsequent tasks (such as classification, tracking), it will often introduce more errors, so i...
