Abstract

The embodiment of the invention discloses a data simulation method and a device for an event camera. A specific embodiment of the method comprises the following steps: decoding a to-be-processed video to obtain a video frame sequence; inputting a target video frame in the video frame sequence into a full convolutional network UNet to obtain event camera threshold distribution information; sampling each pixel in the target video frame to obtain an event camera threshold set; performing pseudo-parallel event data simulation generation processing on the event camera threshold set and the video frame sequence to obtain simulation event camera data; performing generative adversarial learning on simulation event camera data and event camera shooting data to obtain updated event camera threshold distribution information; and generating simulation event camera data based on the updated event camera threshold distribution information, the video frame sequence and the preset noise signal. The method can be widely applied to computer vision systems in the fields of national defense and military, film and television production, public safety and the like.

Description

Technical field [0001] The present invention relates to the field of computer vision and multimode generation, and specific to data simulation methods and apparatus relating to an event camera. Background technique [0002] The event camera has a high dynamic range, low-time delay, and the like due to its imaging principle. There is a wide range of application prospects in the fields of national defense military, film and television production, public safety. However, now the event camera has not spread due to its high price and commercial products. Using event data simulation generation algorithm rapid, cheap simulation generates a large number of event camera data, it is of great significance in the field of image repair, video surveillance, smart city and other applications. Inventive content [0003] The content portion of the present disclosure is used to introduce a concept in a brief form, which will be described in detail in the following detailed description. The conten...
