the mutual inspection of laser pointer

Figure 1 is a schematic diagram of this method, light emitted from the semiconductor laser, focused into a spot by the irradiation in the measured object surface, the scattered light received by the imaging lens, and the spot on the CCD image sensor on the receiver. The inspection includes the self-inspection of laser pointer and the mutual inspection of laser pointer .
If the measured surface in the plane, then the focus point of light into the receiving element as the center of 0:00 on; If and when the measured surface in position A, is focused into a spot like the P1 side of the point 0, When measuring the surface at position B, then focused into a spot as 0 on the other side of P2. Based on the triangular relationship, by the receiving element and the image point on the distance from the center 0, the measured surface can be drawn with the datum of the deviation; by the receiving element in which the different points on the imaging side shows the different symbols may determine to be the direction of the surface deviate from the plane of measurement. Robot laser detection system consists of three parts, namely a robot, a laser detection system and a data processing computer terminal. Figure 2 Schematic diagram of the robot work. Laser detection system for a non-contact sensor unit composed of three-dimensional vision, which consists of two 45 ° direction of the symmetrical configuration of the laser sensor and a CCD camera in the center line (Figure 3-1). Laser-based sensor to detect the surface of the workpiece location of a point in space; camera is used to determine the surface of a workpiece based on the size and shape of the hole (Figure 3-2). The output of the best production month of laser pointer is the highest.
In general, the three points to determine a hole, but holes in the detection in order to ensure the size and shape can be more select number of points by finding the center of irregular objects, features an edge or corner to determine the shape of the object . The mechanical part of the system has three degrees of freedom is a precision motion mechanism, similar to the single-column type coordinate measuring machine, exercise flexibility and accuracy are good.
