Abstract: An object detection method and an electronic apparatus are provided. A processor is configured to perform the following. An original image is received. A plurality of initial feature layers of different scales is extracted from the original image. A plurality of fused feature layers of different scales is obtained through an interpolation and an addition operation based on the initial feature layers. The fused feature layers are respectively input into corresponding detection heads to obtain a bounding box location probability distribution through a bounding box regression branch of the detection head and obtain a classification probability distribution through a classification branch of the detection head.
