The invention relates to a millimeter-wave radar target detection method for low false alarm processing in a complex environment, and the method comprises the steps: judging whether background initialization processing needs to be carried out or not after a millimeter-wave radar receives an elevator car working mode instruction; entering a background learning mode, ensuring that backgrounds of detection areas inside and outside the elevator door are clean and no moving target exists, and collecting point cloud information of each target under the current background; or directly entering a normal working mode, and starting to collect the target point cloud information after receiving a signal that the elevator door is opened; preliminarily screening the collected point cloud information according to a set ROI (Region of Interest) threshold value, and screening out a target point cloud number set of which each frame accords with the threshold value; and performing sliding averaging on the obtained target point cloud number set, and performing corresponding mode selection processing. The invention further relates to a corresponding device, a processor and a storage medium of the processor, the target and the moving trend of the target can be rapidly and accurately perceived in the complex environment, the false alarm rate is low, and the elevator running safety is improved.
本发明涉及一种复杂环境下针对低虚警处理的毫米波雷达目标检测方法,包括:毫米波雷达接收到电梯轿厢工作模式指令后,判断是否需要进行背景初始化处理;进入背景学习模式,确保电梯门内外检测区域背景干净并无移动目标,采集当前背景下各目标的点云信息;或者直接进入正常工作模式,当接收到电梯门打开的信号后,开始采集目标点云信息;按照设定的ROI阈值对采集到的点云信息进行初筛,筛选出各帧符合阈值的目标点云数集;对获取到的目标点云数集进行滑动取平均,并进行相应的模式选择处理。本发明还涉及一种相应的装置、处理器及其存储介质,在复杂环境下可以快速准确感知目标及其移动趋势,虚警率低,提高了电梯运行的安全性。
