A light source emits light to an object during an emission period. A sensor converts received reflected light (delay time τ) into an electrical signal during a plurality of signal accumulation periods, and accommodates the electrical signal. The signal accumulation period is set so that an accumulated signal amount varies depending on a distance to the object. The emission intensity of the light source is changed during the emission period so that the accumulated signal amount and the distance to the object has a nonlinear relationship."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distance measuring method and distance measuring system","description":"In a TOF distance measurement employing light, the accuracy of distance measurement is improved without a significant increase in cost.
