Multi-scale target detection method and device, computer device and storage medium

Abstract

The invention discloses a multi-scale target detection method and device, a computer device and a storage medium. The method comprises the following steps: obtaining initial images, amplifying the initial image for several times; forming image pyramids, inputting the data into a preset feature pyramid network; carrying out recognition and frame selection positioning processing on a target in the initial image through a preset feature pyramid network; obtaining a first prediction result, meanwhile, amplifying the initial image according to a preset mode; obtaining enlarged images, inputting theamplified image into a preset small-scale target detection network; performing feature extraction and classification on the amplified image through a preset small-scale target detection network, to obtain a second prediction result, collecting and analyzing the first prediction result and the second prediction result, to obtain the target detection result. Accuracy of multi-scale target detectionand positioning is improved by the combination of the feature pyramid network and the small-scale target detection network.

Description

technical field [0001] The present invention relates to the field of image recognition, in particular to a multi-scale target detection method, device, computer equipment and storage medium. Background technique [0002] With the continuous development of artificial intelligence technology, people have also put forward new requirements for computers. In addition to learning Go, people hope that computers can autonomously detect objects in life, which promotes the development and innovation in the field of computer vision. Computer vision is to enable machines to have visual capabilities similar to humans. It detects input image information, recognizes objects and environments in images, and gives corresponding understanding. Computer vision uses cameras to simulate people observing the world, but to understand the world, technicians need to process the information collected by cameras. Computer vision involves many research fields, such as: target detection, target trackin...
