Abstract

The invention discloses a target detection method and device based on computer vision in a complex environment, and the method comprises the steps: collecting an RGB image of a foreground region, carrying out the preprocessing of the RGB image of the foreground region, and obtaining a foreground target region segmentation binary image; analyzing the foreground target area segmentation binary image, and extracting various morphological features of the target area; analyzing various morphological characteristics of the target area, and dividing the target area into a shielded isolated target area and an overlapped target area; carrying out contour segmentation on the shielded isolated target area and the overlapped target area, and extracting effective contour segments; performing circle fitting on the target shape in the effective contour fragment by adopting a circle fitting method, performing comprehensive analysis on a fitted circle, and positioning a potential target area; eliminating interference, and identifying and obtaining a specific target of the potential target area; according to the embodiment of the invention, the target instance detection accuracy of a natural complex environment can be improved.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a target detection method based on computer vision in a complex environment. Background technique [0002] RGB images collected from natural and complex environments usually contain target objects and other non-target objects, but non-target objects in different scenes usually show different color characteristics, in which target objects can clearly distinguish non-target objects, so the color difference method can be used. Perform target area extraction. [0003] Most of the targets in the images collected in the natural complex environment have overlapping areas or are occluded by other non-target objects, so that the potential foreground area of ​​the extracted target has the phenomenon of target adhesion or missing local areas of the target, and it is difficult to accurately locate the target area. Affects the target segmentation effect. Even the texture features of...
