Abstract

An optical detection device of detecting whether a target object has different surface treatment features includes an image sensor and an operation processor. The image sensor is adapted to acquire a detection image containing the target object. The operation processor is electrically connected to the image sensor, and adapted to compute variation of an image shading parameter of the detection image so as to determine whether a boundary of the surface treatment features are detected by the image sensor in accordance with the variation of the image shading parameter.
