Embodiment Construction

[0048] The specific implementation manners of the present application will be further described in detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0049] First, some terms involved in this application are introduced.

[0050] Center-based detection network (CenterNet): is an end-to-end object detector. Object detection requires the detection of the smallest rectangular box containing an object. Traditional object detectors usually list and classify a large number of candidate boxes. And CenterNet locates the target to be detected to a point, that is, the center point of the detection rectangle. In other words, in CenterNet, each center point corresponds to the position of a target, and there is no need to judge the overlapping of rectangular boxes. The speed and efficiency of target detection are higher than those of traditional targ...

Abstract

The invention relates to an object analysis method and device and a storage medium, and belongs to the technical field of computers. The method comprises the steps: acquiring a target image; inputting the target image into a pre-trained image recognition model to obtain an object analysis result of the target image, wherein the object analysis result includes target object position information, target object key point information and target object attribute information; therefore, the problem that an existing target detection algorithm cannot realize simultaneous improvement of speed and accuracy can be solved. Information contained in the obtained feature layer is richer and more comprehensive by using a fusion mode, and the detection accuracy is improved while the sensitivity of identifying targets of different scales is improved; the reasoning time of the fusion part of the feature layer can be shortened by using the depth separable convolution; by integrating the attribute analysis function, one model has three functions of target detection, key point prediction and attribute output at the same time, the video memory occupancy rate of the three functions is reduced, and the running speed of the model in the system is also improved.

Description

【Technical field】 [0001] The present application relates to an object analysis method, device and storage medium, belonging to the technical field of computers. 【Background technique】 [0002] With the development of artificial intelligence technology, more and more target detection algorithms have emerged. Such as anchor-free series algorithms, etc. [0003] The anchor-free series algorithm avoids the preset of the anchor box, reduces a lot of related calculations, and significantly improves its memory usage and speed. Moreover, there is no presetting of the anchor frame, and the prediction frame returns the target position within the entire feature map range, which is suitable for the detection of target objects of various shapes and sizes. [0004] However, the existing target detection algorithm will reduce the accuracy of the algorithm while improving the speed of the algorithm, resulting in the problem of inaccurate target detection results. 【Content of invention】 ...
