The line laser generation module projects a line laser beam to a first direction from a first position. The image capturing module at a second position captures a ranging image in the first direction. When the ranging image includes a calibration target image of a calibration target having a first width, the processing module calculates a measured width of the calibration target according to a position of a line spot image of a laser spot on the calibration target image, obtains a calibration parameter according to the first width and the measured width, performs range finding according to the laser spot shown in the ranging image, and performs a calibration task using a calibration parameter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Laser ranging calibration method and apparatus using the same","description":"The disclosure relates to a laser ranging calibration method and a laser range finder including a line laser generation module, an image capturing module and a processing module.
