Automatic detection system for laser level meter and detection method

Abstract

The invention provides an automatic detection system for a laser level meter. The automatic detection system for the laser level meter comprises a vertical detection station, wherein the vertical detection station is used for detecting a vertical laser line, and the station is provided with a pentaprism for deflecting the vertical laser line to a horizontal laser line; a horizontal detection station, wherein the horizontal detection station is used for detecting the horizontal laser line; an optical collimator, wherein the optical collimator is internally provided with an objective lens and areticle, the position of the objective lens is opposite to the position of the reticle, and the laser line is projected to the reticle after passing through the objective lens; a camera, wherein the camera is used for collecting a laser image on the reticle; and a computer, wherein the camera is connected with the computer, the computer is used for analyzing and calculating the image collected bythe camera. The technical scheme is capable of automatically and accurately measuring angles of the vertical and horizontal laser lines emitted by the laser level meter, greatly shortening the testingtime, improving the efficiency, realizing the measurement to the vertical laser line and the horizontal laser line by a set of the optical collimator and the camera, reducing the cost, and decreasingthe spatial arrangement of a detection device.

Description

technical field [0001] The invention belongs to the fields of optical detection, machine vision and the like, and in particular relates to an automatic detection device and a detection method for detecting laser lines emitted by a laser level meter. Background technique [0002] Laser levels can emit laser lines and project them on the target to generate horizontal or vertical lines for reference. They are widely used in engineering, construction, decoration and other fields. The angle of the laser line emitted by the laser level is the angle between the laser line and the horizontal plane or the vertical plane where the exit point is located. It is an important indicator to measure the accuracy of the laser level. Angle detection is usually used as a final inspection item on the laser level production line to ensure The product is of acceptable quality after processing and assembly. At present, most of the domestically produced laser levels are judged by human-eye observat...
