Abstract

The invention discloses a target object detection method and device, a storage medium and a terminal. The method comprises the following steps: acquiring a to-be-recognized image; inputting a to-be-recognized image into the first granularity machine learning model, outputting a first background image and inputting the to-be-recognized image into the second granularity machine learning model, and outputting a second background image, wherein the first updating period of the first granularity machine learning model is larger than the second updating period of the second granularity machine learning model; and determining a target object based on a comparison result of the first background image and the second background image. The technical problem that the foreign matter detection effect is not ideal due to the fact that the detection accuracy of the foreign matter on the road is low in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, to a method and device for detecting a target object, a storage medium and a terminal. Background technique [0002] In the related art, when detecting foreign objects or obstacles (such as road gravel, branches, etc.) in areas such as roads and parks, it is generally detected by a moving target detection method, which is often aimed at larger objects. , such as vehicles driving on the road, pedestrians on the road, etc., to realize the detection of large foreign objects or obstacles; however, due to the wide variety of foreign objects on the road, different sizes, shapes, and colors, the foreign objects cannot be calibrated. The detection accuracy of foreign objects with small size, large shape change, and close color and background is low, resulting in unsatisfactory foreign object detection effect, and road light and shadow will have a greater impact on the ...
