The invention discloses a device for foreign body invasion detection and a method for foreign body invasion detection. A monocular camera is configured to be able to transmit an image within a monitoring range to an image collecting and processing system. A laser trace control system is configured to be able to control a single-point laser range finder to rotate and pitch according to a rotating angle and a pitching angle, the single-point laser range finder measures the straight-line distance between a foreign body and the single-point laser range finder, and the straight-line distance is transmitted to the image collecting and processing system. According to the received image, the image collecting and processing system judges whether a suspected foreign body appears within the monitoring range of the monocular camera or not, obtains the image and the image point of the suspected foreign body when the suspected foreign body appears, calculates the position and the azimuth angle of the suspected foreign body in camera coordinates of the corresponding monocular camera, and calculates the rotating angle and the pitching angle used for the single-point laser range finder by using the obtained position and azimuth angle. The image collecting and processing system uses the received straight-line distance and the suspected foreign body image for restoring the actual position and size of the foreign body to judge whether the suspected foreign body is an invading foreign body or not.
