Problems solved by technology
Because the performance of the sensors is largely dependent on the integrity of the lens, they are also not suitable for deployment in outdoor and humid environments, where the lens will become blurred due to the accumulation of mold and dust, and the cost is relatively high. High, the induction is greatly affected by the environment, resulting in low reliability and error-prone

The invention discloses a distance measuring method and device based on a radar sensor and a storage medium. The distance measuring method based on the radar sensor comprises the steps: emitting a detection signal according to a preset period to obtain an induction signal reflected by a target object; detecting continuous induction signals and acquiring the induction signals; preprocessing the induction signal to obtain a continuous Doppler signal; judging whether the plurality of Doppler signals are matched and the number of times; processing the plurality of continuously matched Doppler signals to obtain the moving direction of the target object; and after judgment and confirmation, outputting the moving directions of a plurality of continuous target objects. According to the invention,the anti-interference capability, the induction accuracy and the reliability of induction are improved, the application range is wide, various application environments can be adapted, the realized scheme is simple, and the cost is low.
Description
technical field [0001] The invention relates to the technical field of ranging by radar sensors, in particular to a ranging method, device and storage medium based on radar sensors. Background technique [0002] Existing sensing technologies are used for non-contact sensing, obstacle detection and safety sensors such as passive infrared, ultrasonic, laser, lidar and cameras, etc. Usually these sensors need to have a lens, which makes them unsuitable for privacy-preserving applications Applications such as automatic toilets, restroom automation and hotel rooms. Because the performance of the sensors is largely dependent on the integrity of the lens, they are also not suitable for deployment in outdoor and humid environments, where the lens will become blurred due to the accumulation of mold and dust, and the cost is relatively high. High, the induction is greatly affected by the environment, resulting in low reliability and error-prone. Contents of the invention [0003] ...
