Abstract

The invention discloses a small target detection method based on robot vision. The small target detection method uses a wavelet transform detection method to detect a small target. After the wavelet transform, the energy of a horizontal sub-graph and a vertical sub-graph are multiplied by a low-frequency sub-graph, a target signal is enhanced through weighting processing, noise signals are suppressed, a clear image is obtained, noise interference is avoided to a certain extent, the method can clearly detect small target objects, and a median filtering technique is used to process live small target images.

Description

Background technique [0001] The invention of robots is used to help humans solve and deal with some high-risk and high-injury things. It can replace us in complex and labor-intensive work and reduce our burden. At present, there are still certain limitations in small target detection. Robots The detection and judgment of small targets lack autonomy, and the obtained images are often disturbed by noise and so on. Contents of the invention [0002] In order to solve the above-mentioned problems, the present invention provides a detection method capable of accurately detecting small targets, processing the resulting pictures, and reducing external interference. [0003] In order to achieve the above object, the present invention is achieved through the following technical solutions: [0004] The present invention is a kind of small target detection method based on robot vision, comprises the robot with binocular stereo vision and transmission function, image processing system,...
