OBJECT DETECTION DEVICE

摘要

An object detection device includes a light source, an irradiation optical system that converts emitted light from the light source to measurement light having a predetermined pattern and emits the measurement light to a reference surface, and a light reception element that images the reference surface, and includes an imaging member that reads an image captured by the light reception element for each of a plurality of lines extending in a horizontal direction and arranged at predetermined intervals, and a detection unit that detects an object to be measured entering between a pattern forming unit and the reference surface based on image data from the imaging element, in which the pattern includes a plurality of division patterns arranged in the horizontal direction to correspond to the lines in the reference surface.

1. An object detection device, comprising:
a light source configured to emit light; an irradiation optical system configured to convert the light emitted from the light source to measurement light having a predetermined pattern, and emit the measurement light to a reference surface; an imaging device including a light reception element configured to capture an image by receiving the measurement light reflected by the reference surface or an object entered between the irradiation optical system and the reference surface, the imaging device reading the captured image line by line along a plurality of lines extending in a horizontal direction and arranged at a predetermined interval so as to output image data; and a detection unit configured to detect the object based on the image data from the imaging device, wherein the predetermined pattern of the measurement light includes a plurality of divided patterns each arranged in the horizontal direction, each divided pattern corresponding to respective one of the plurality of lines for capturing the image at the reference surface.
