Problems solved by technology
[0004] Among them, detecting the position of the image area where the obstacle object in the image is located is realized by the detection model. In the prior art, when using the detection model to detect the obstacle object in the image, if the background image in the image (that is, the image except for the obstacle The image other than the object) is more complex, the complex background image will cause greater interference to the detection process of the detection model for the obstacle object, resulting in the position of the image area where the obstacle object in the image finally detected by the detection model is not accurate. precise

The present application discloses an image object detection method, device, and computer-readable storage medium. The method includes: acquiring a sample image containing a detection object; The predicted object image area where the detection object is located; obtain the predicted position distribution of the detected object in the predicted object image area; obtain the position distribution difference between the predicted position distribution and the center position distribution; the center position distribution is the detection object in the actual image area The position distribution in ; according to the position distribution difference, the distribution difference loss is obtained, based on the distribution difference loss, the predicted object image area where the detection object is located, and the location label information, the model parameters of the original detection model are corrected, and the position used to identify the object in the image is obtained detection model. By adopting the present application, the detection accuracy for the position of the object in the image can be improved.
Description
technical field [0001] The present application relates to the technical field of image processing, and in particular to an image object detection method, device and computer-readable storage medium based on artificial intelligence technology. Background technique [0002] With the continuous development of computer networks, image detection technology needs to be used in more and more life scenes. Among them, image detection can refer to the detection of specific objects in the image, so as to detect the specific objects in the image. The location of the object. [0003] For example, during the driving process of an unmanned car, the car can use the installed camera to capture the scene in front of the car's field of view, and obtain frame by frame images. The car can detect each captured frame of image, so as to detect the image area where the obstacle object in each frame of image is located, and then can calculate the position of the image area where the obstacle object ...
