The invention discloses an automatic detecting method and system for product appearance. The automatic detecting method comprises the following steps that S1, an industrial robot is controlled to drive a reference ball and a distance sensor which are arranged at the tail end of the industrial robot to move according to a preset moving track to enable the reference ball and the distance sensor to detect a target detecting point on a to-be-detected workpiece; S2, a coordinate of target points on the reference ball which is shot in a tracking mode by a three-dimensional tracking device is obtained, and a pose of the reference ball under a coordinate system of the three-dimensional tracking device is calculated; and S3, coordinates of the target detecting points are calculated according to thepose of the reference ball under the coordinate system of the three-dimensional tracking device and distance data detected by the distance sensor. According to the automatic detecting method and system for the product appear
