Example Embodiment

[0026] The concept of the present invention is: using the human eye's characteristic of being sensitive to moving objects, imitating the working mechanism of the visual system, reducing the amount of transmitted data and transmitting data in parallel can improve the running speed of the system and meet real-time requirements. The invention selects an image sensor based on Address-Event Representation (AER) as the information collection source of the moving object, and inputs the collected image data into the back-end bionic processing system in parallel; The raw image data is processed by fast parallel calculation, the moving target is extracted, the target position parameter is calculated, and the processing result is displayed in real time. The back-end bionic processing system includes two modules, feature extraction module and target recognition module.

[0027] The input data of the feature extraction module is provided by an AER image sensor with an N×N pixel array, wher...

Abstract

The present invention relates to the field of image processing technology. In order to realize real-time acquisition and processing of image information collected from an AER image sensor, an event-based processing method is always adopted in a rear-end bionic visual system processing stage to realize the target recognition function and provide target position parameters. A bionic target identification system based on event driving comprises an image sensor representing AER based on address-event, and a rear-end bionic processing system, wherein the AEM image sensor is used as an information acquisition source of moving objects, and the acquired image data is inputted in parallel to the rear-end bionic processing system. The bionic target identification system further comprises a feature extraction module for processing input image data by using feature extraction algorithm based on event driving, and a target identification module based on event driving, wherein the target identification module employs SNN (spiking neural network) to process the output of the feature extraction module. The bionic target identification system is mainly used for image processing.
