Abstract

An automatic parameter calibration method and system. The automatic parameter calibration method comprises: putting a floor sweeping robot at a designated position, wherein the designated position is arranged relative to a distance measurement device (2), and a distance measurement sensor of the floor sweeping robot faces a distance measurement baffle plate (4) of the distance measurement device (2). The method comprises the following steps: receiving the real distance, sent by the distance measurement device (2), between the distance measurement sensor and the distance measurement baffle plate (4), and acquiring a measured distance, obtained through measurement by the distance measurement sensor, between the distance measurement sensor and the distance measurement baffle plate (4) (S10); and according to the real distance and the measured distance, calibrating the parameters of the distance measurement sensor (S20).

Description

technical field [0001] The invention relates to the field of parameter calibration, in particular to an automatic parameter calibration method and system. Background technique [0002] With the advancement of science and technology, especially the development of artificial intelligence technology, automation equipment has been widely used. For example, household service robots have occupied an increasing market in recent years. [0003] Most of these automation devices will install some measurement sensors around the machine, such as infrared, ultrasonic, etc., to actively sense the environment around the robot. However, in the production process, there are certain differences in the thresholds or parameters for different batches of sensors; in addition, if the components are replaced, the thresholds or parameters will also be different, and it is troublesome to manually test and modify each time. Contents of the invention [0004] The main purpose of the present inventi...
