Title:
COLLIDING OBJECT IDENTIFICATION METHOD, SYSTEM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/087372
Kind Code:
A1
Abstract:
A colliding object identification method, a system and a storage medium. The method acquires a collision intensity signal generated by a sensor when a colliding object collides with a mobile robot, and analyzes the collision intensity signal in a frequency domain, to obtain a frequency spectrum corresponding to the collision intensity signal. When different types of colliding objects collide with the mobile robot, the frequency spectrum corresponding to the collision intensity signal generated by the sensor is different, and when the same colliding object collides with different positions of the mobile robot, the frequency spectrum corresponding to the collision intensity signal generated by the sensor is also different, and therefore the type and/or the colliding position of the colliding object can be accurately determined according to a plurality of frequency points in the frequency spectrum. Especially when a small high-speed projectile and a big low-speed projectile collide with an armor panel of the mobile robot, the intensity of the colliding force applied to the armor panel may be very close, but the frequency spectrum of the collision intensity signal generated by the sensor is different, and therefore the small projectile and the big projectile can be accurately identified by means of the plurality of frequency points in the frequency spectrum.
