The invention provides a laser triangular and optical lever composite monocular vision measuring device in the technical field of measurement, and the device comprises a base plate, wherein a connecting frame is fixedly connected to the upper side of the base plate, the connecting frame is rotatably connected with a lens bracket for mounting a lens and a mounting bracket for mounting a laser, thecenter line of the lens and the axis of the laser light source are in a plane, the connecting frame at the facing outwardly end at which the lens bracket is located away from the mounting bracket is fixedly connected with a fixed bracket and is rotatably connected with an adjustment bracket, a first plane mirror is slidably connected to the adjustment bracket, a second plane mirror that is slidable up and down is connected to the fixed bracket, the emitting surface of the first plane mirror and the emitting surface of the second plane mirror are opposite to each other, and the connecting frameabove the first plane mirror is connected with photographing equipment facing the second plane mirror. The laser triangular and optical lever composite monocular vision measuring device provided by the invention is simple in structure and high in resolution, and improves the accuracy of micro displacement measurement.
Description
technical field [0001] The invention relates to the technical field of measurement, in particular to a laser triangle and optical lever composite monocular vision measuring device. Background technique [0002] With the continuous development of processing and manufacturing technology, the demand for non-contact measuring devices for micro-displacement continues to increase. In the prior art, laser triangulation is often used to measure the micro-displacement of an object non-contact. When this method is used for detection, the light emitted by the laser is irradiated on the upper side of the object, and the light irradiated on the upper side of the object is refracted through the lens imaging, and the refracted light The light spot is projected on a projection board, and the photographic equipment takes pictures of the light spot on the projection board to obtain the position coordinates of the light spot, but the light spot is very small. When the object has a slight displ...
