PURPOSE: A surface angle measurement optical sensor and a surface angle and shape information sensing method are provided to measure the distance to a target object by using images of which specificity is removed. CONSTITUTION: A surface angle measurement optical sensor includes a plurality of lighting units (100), a photographing element (200), a memory unit (300), and a control unit (400). The lighting units are mounted at different spots and angles and irradiate measurement light of different properties to a sensing domain. The photographing element senses lights incident from the sensing domain, thereby obtaining images in respect to the sensing domain. The memory unit stores the images or results images in which the images are image-processed. The control unit includes an exposure control unit (410), an image processing unit (420), and a three-dimensional restoration unit (430). The exposure control unit controls light-emitting time for emitting the measurement light of the lighting units and the photographing time of the photographing element. The image processing unit removes disturbance due to an external light emitting body from a plurality of images returned from sensing domain by being reflected and separates the effects of the lighting units, thereby extracting the images as individual measurement images.
