Distance measurement device, model generation device, information generation device, information generation method, and program

As an example, it is possible to enumerate the influence of attachments generated on an exit window of a distance measuring device on distance measuring properties. This distance measuring device (10) emits light output from a light source (14) through a transmission member (20) and detects reflected light from an object. A distance measuring device (10) is provided with a light receiving unit (180) and an information generating unit (121). The light receiving unit (180) receives at least internally reflected light including the reflected light reflected by the transmission member (20). The information generation unit (121) generates information relating to the distance measurement performance of the distance measurement device (10) using the light reception result of the internally reflected light generated by the light reception unit (180). 作为本发明要解决的课题，作为一例，可列举确定在测距装置的出射窗上产生的附着物对测距性的影响。本发明的测距装置(10)是使从光源(14)输出的光经由透射构件(20)出射并检测来自对象物的反射光的装置。测距装置(10)具备受光部(180)及信息生成部(121)。受光部(180)至少接受内部反射光，所述内部反射光包括由透射构件(20)反射的反
