The invention discloses a positioning detection system and a positioning detection method for defects of a transparent screen. The system comprises a linear slide rail; the transparent object carrying platform is arranged on the linear sliding rail, and the transparent object carrying platform is driven by a motor to move; the lower surface is provided with a mirror reflection layer, the upper surface is used for placing a detection object, and the detection object is a transparent screen; a first optical axis of the first camera is perpendicular to the plane where the detection object is located; an angle alpha is formed between a second optical axis of the second camera and the first optical axis, and alpha is smaller than 90 degrees; the light source is arranged above the transparent carrying platform; and the data processing unit is used for processing the acquired image of the first camera and the acquired image of the second camera to realize three-dimensional positioning detection.
