Abstract

The invention relates to a multi-ball board standard for a multi-sensor measurement system. The multi-ball board standard comprises a board body. Standard balls are distributed on the upper surface of the board body according to a topological structure. The topological structure comprises primary nodes extending along a regular square or octagonal path. The primary nodes at least derive out secondary nodes. Two adjacent upper-level nodes constitute a derivative group and derive out two lower-level nodes. The two upper-level nodes in each derivative group derive out respective lower-level nodes at equal distances along the directions of rays which take the two upper-level nodes as the endpoints and form an angle of 135 degrees with the connecting line of the two upper-level nodes. The invention further relates to a joint error detection method comprising the following steps: standard balls are numbered using the 10-ball standard of the invention; actual values, including the diameter of the standard balls, are measured; sensors sample the standard balls in sequence according to a sampling path; the center coordinates of the standard balls and the measured value of ball diameter are calculated; and each joint error is calculated, and whether each joint error is qualified or not is judged.

Description

technical field [0001] The invention relates to a standard, in particular to a standard for calibration, error correction and coordinate value traceability for a multi-sensor measurement system. The invention also relates to a method for detecting joint multi-sensor errors. Background technique [0002] With the rapid development of advanced manufacturing fields such as automobiles and motorcycles, aerospace, high-speed rail, ships, and medical equipment, a large number of high-end products use complex parts. These parts have the characteristics of multi-scale feature size and difficult measurement, and their accuracy directly affects the product. Final quality and service life. No single sensor can measure all the characteristics of such parts. In the field of geometric quantity measurement, the multi-sensor coordinate measurement system has become an important means of high-precision measurement of multiple elements of complex parts by taking advantage of the complementa...
