Single-photon imaging device and imaging method based on event detection

Abstract

The invention discloses a single-photon imaging device and an imaging method based on event detection. The transmission flow, the storage capacity and the calculation amount of a rear-end processor are greatly reduced and the overall application efficiency is effectively improved through carrying out event judgment, event detection and event control, and outputting event signals with dynamic frame rate and resolution. A power management module predicts the power consumption change trend of the processor according to the number of the event signals and controls the power supply module to adjust power output, so that the energy-saving effect is achieved, and the requirement of ultra-low power consumption application is met.

Description

technical field [0001] The present application relates to a single-photon imaging device, in particular to a single-photon imaging device and an imaging method based on event detection. Background technique [0002] Traditional single-photon imaging equipment captures and acquires images at a constant frequency, and transmits the acquired image data to the artificial intelligence processor (AIP) for analysis and processing. There is a certain delay problem. Real-time performance has high requirements, and the transmitted image contains a large amount of invalid information, which must be processed in real time by AIP, resulting in the problem that the traditional single-photon imaging sensor combined with AIP consumes a lot of power, and a large amount of invalid information needs to be processed in real time. The requirement for data transmission and storage capacity requires large transmission bandwidth and high computing processing capacity, which consumes a lot of resour...

[0002] Traditional single-photon imaging equipment captures and acquires images at a constant frequency, and transmits the acquired image data to the artificial intelligence processor (AIP) for analysis and processing. There is a certain delay problem. Real-time performance has high requirements, and the transmitted image contains a large amount of invalid information, which must be processed in real time by AIP, resulting in the problem that the traditional single-photon imaging sensor combined with AIP consumes a lot of power, and a large amount of invalid information needs to be processed in real time. The requirement for data transmission and storage capacity requires large transmission bandwidth and high computing processing capacity, which consumes a lot of resources and reduces the effect and accuracy of real-time processing
