AI Technical Summary

Technical Problem

Existing technologies, such as temporal difference methods, have low computational efficiency and high resource consumption in grayscale and morphological processing for high-resolution, high-frame-rate video scenarios, making it difficult to meet the real-time motion detection requirements of the edge.

Method used

The SIMD instruction set is used for hierarchical and block-based parallel processing. By executing a preset SIMD instruction sequence, the absolute value vector of the difference between the RGB three channels is split and parallelized for grayscale multiplication and addition. Combined with morphological dilation and erosion processing, the computational efficiency is improved.

Benefits of technology

It reduces the computational overhead and latency of frame difference grayscale processing, alleviates the processor load, and improves the real-time processing capability of motion detection.

Abstract

本发明实施例公开了一种移动侦测装置、方法、芯片、板卡及电子设备,该移动侦测装置包括:灰度化处理单元,用于通过执行预设的第一SIMD指令序列,对当前帧数据与历史帧数据的RGB三通道差值绝对值向量进行至少两级拆分,每级拆分将待拆分向量拆分为至少两个数据子块,前一级拆分得到的数据子块作为下一级拆分的待拆分向量,对最终拆分得到的各数据子块进行并行灰度化乘加运算,得到灰度值结果向量,其中,最终拆分得到的各数据子块能够通过单次向量乘加指令完成并行灰度化乘加运算。本发明提高了移动侦测中灰度化处理的效率,降低了帧差灰度化处理的计算开销与处理时延,减轻了处理器负载,有助于提高移动侦测的实时处理能力。
