Problems solved by technology

[0003] Converting the signal into a human-visible display form is the first step to intuitively understand the pulse signal. Since most of the existing machine learning algorithms cannot directly process the pulse signal as a data source, it is necessary to provide a method that can visualize the pulse signal. Technology

Abstract

The invention discloses a display method and system based on pulse signals. The display method comprises the steps of analyzing a pulse sequence and pulse issuing information corresponding to a singlepixel position; Obtaining pixel values corresponding to a plurality of pulse issuing times before the single pulse issuing time, and accumulating the pixel values as a first accumulated pixel value;Setting a first specific quantity corresponding to the single pulse distribution time of the pixel position, and superposing the first specific quantity and a first accumulated pixel value to obtain afirst pixel value of the pixel position; Comparing the relationship between the first pixel value and the pixel threshold range, and adjusting the first specific quantity to obtain a second specificquantity; And superposing the first accumulated pixel value and a second specific quantity to obtain a second pixel value of the pixel position, and generating an image by using each second pixel value. A pixel value is calculated by using the time domain characteristic of a pulse signal, a high-quality image is formed, and an image at any continuous moment is output; The pixel value is adjusted according to the pixel threshold range, and the quality of the generated image is improved.

Description

technical field [0001] The present application relates to the technical field of signal processing, and in particular to a display method and system based on pulse signals. Background technique [0002] Machine vision algorithms based on traditional image sensors have been widely used in many fields such as intelligent security and intelligent transportation. However, due to its own design concept, traditional image sensors are increasingly unable to meet the current visual task requirements. These sensors typically sample the scene at a preset fixed frequency in units of frames. This kind of sampling based on a fixed frame rate cannot reflect the dynamic changes of the scene, and it is easy to oversample or undersample the current scene, resulting in large video data redundancy, low temporal resolution, and easy blurring under high-speed motion. Inspired by the visual sampling mechanism of the biological retina, new cameras that collect pulse array signals have entered pe...
