Abstract

The invention provides a data coding method, apparatus and device, and a readable storage medium. The method comprises the steps of generating a corresponding real-time voltage according to incident light intensity of each pixel in a pixel array of an image sensor; respectively acquiring light intensity change representation data corresponding to each pixel based on the real-time voltage; and coding the respective light intensity change characterization data of a plurality of sub-pixel arrays with the same light intensity change characterization data of all the pixels in the pixel array and the total number of the pixels in sequence to obtain coded data. Due to the fact that events output by adjacent pixels in the pixel array are generally small in difference, through implementation of the scheme, continuous pixels with the same event generation behavior are combined and coded, data can be compact, efficiency is high, the data size is small, the image output frame rate is increased, and the complexity of follow-up decoding is reduced.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a data encoding method, device, equipment and readable storage medium. Background technique [0002] With the continuous development of science and technology, computer vision technology is becoming more and more mature. The emergence of event cameras has attracted more and more attention in the field of vision. It simulates the human retina and responds to pixel pulses of brightness changes due to motion, so it can capture the brightness changes of the scene at a very high frame rate, record events at specific points in time and specific positions in the image, and form event streams instead of Frame stream, thus solving the problems of traditional camera information redundancy, massive data storage and real-time processing. [0003] In the event camera in the related art, after the event generation is completed by the analog components, the digital circu...
