Distance detection device and self-propelled equipment

Abstract

This disclosure provides a distance detection device and a self-propelled device. The distance detection device includes a light-emitting source, a light-receiving mirror, a detection assembly and a controller, wherein the light-receiving mirror and the light-emitting source are spaced apart, the detection assembly is located near the focal plane of the light-receiving mirror, the light-emitting source is configured to emit detection light having a divergence angle toward a target object, the detection assembly is configured to receive reflected light information reflected by the target object and passed through the light-receiving mirror, and the controller is electrically connected to the detection assembly and is configured to determine the measurement distance of the target object based on the reflected light information received by the detection assembly.
