HITTING DETECTION METHOD AND DEVICE, MOVABLE PLATFORM, AND COMPUTER READABLE STORAGE MEDIUM

WIPO Patent Application WO/2020/232669

A1

A hitting detection method and device, a movable platform, and a computer readable storage medium. The hitting detection device is adapted to be fixedly mounted on the inner side of an object under test; an annular protrusion is provided on an upper cover of the hitting detection device, and is used for defining a cavity together with the object under test. The method comprises: obtaining a sound signal by means of a microphone configured in the hitting detection device (101); and detecting the sound signal by means of a preset hitting detection algorithm, and determining whether the object under test is hit (102). By providing the annular protrusion on the hitting detection device, a cavity is defined between the annular protrusion and the object under test, the signal quality of a sound signal obtained by a microphone is improved, and the precision in hitting detection is improved.
