Problems solved by technology
At present, the commonly used measuring devices are laser interferometer and laser tracker. Since the laser interferometer can only measure the error of one axis at a time, it must be replaced in order to measure the error of different items during the measurement process. The lens group is then used to measure different items, making the operation process quite time-consuming
As for the laser tracker, although it can detect quickly and with high precision, it is extremely expensive

Description
technical field [0001] The disclosure relates to a measuring device, in particular to a three-dimensional measuring device and a calibration method for an applicable mechanical arm. Background technique [0002] With the advancement of industrial technology, various automation devices have been widely developed for application in life and industry. In general, a robotic arm is an important element of an automation device. Although the stability of processing with a robotic arm is far greater than that of manual labor, the precision of the robotic arm is generally not high due to the accumulation and transmission of multiple errors due to too many joints in the robotic arm. In order to improve the machining accuracy of the robotic arm, it is necessary to use a measuring device to calibrate the robotic arm before machining with the robotic arm, so as to improve the machining accuracy. At present, the commonly used measurement devices are laser interferometer and laser tracke...
