Abstract: Embodiments of the present disclosure disclose a method and apparatus for detecting a target object, an electronic device, and a computer readable storage medium, relate to the fields of computer vision, deep learning, and smart transportation. A specific embodiment of the method includes: acquiring a to-be-detected image; processing the to-be-detected image using an object detection model including a deformable convolutional layer to obtain an offset prediction result of the deformable convolutional layer; and adjusting a size of an anchor point using the offset prediction result, and determining position information of the target object in the to-be-detected image using the anchor point of the adjusted size. In this embodiment, the deformable convolutional layer is applied to reduce a feature difference between objects of different sizes, and the offset prediction result of the deformable convolutional layer is used to guide to adjust the size of the anchor point, so that the anchor point of the adjusted size is consistent with the size of the target object. Further, more accurate object detection may be achieved by using the anchor point corresponding to the size of the target object.
