Detailed Description
In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
As described above, a profiler can measure profile and dimensional parameters of an object during 3D printing. The measured profile and dimensional parameters may be used for, for example, 3D printer system calibration or defect detection for printed objects. A profiler for a 3D printer typically includes a camera for projecting laser light toward an object and a laser for receiving light reflected by the object for imaging. The positional relationship between the laser and the camera needs to satisfy a high accuracy requirement, and therefore, there is also a high requirement for the mounting accuracy of the camera and the laser. If the installation accuracy is low, it may cause inaccurate system calibration of the 3D printer or inaccurate defect detection for the printed object.
For example, a profiler of a 3D printer may include two lasers capable of emitting line lasers, which may each need to be mounted at an angle. If the angle of installation deviates, it may lead to inaccuracy in defect detection.
