Abstract
Embodiments of the present disclosure provide a distance measurement method and device, a robot and a storage medium. The method comprises: acquiring a first image, where the first image at least comprises a to-be-detected object and a ground on which the to-be-detected object is located; determining an initial constraint condition of the ground based on the first image; acquiring a second image, where the second image at least comprises an intersection line of a line structured light beam with the ground and/or with the to-be-detected object; determining a position parameter of the ground based on the second image, and correcting the initial constraint condition of the ground based on the position parameter; and determining a distance to the to-be-detected object based on the corrected initial constraint condition of the ground and the first image.
