3) start servo motor, while opening laser radar, sliding block is made to drive laser radar from scan start point to scanning
Terminal is mobile, is scanned to high-iron carriage, receives data, and transfer data to host computer；
4) host computer screens the data received, rejects partial data, only retains the number within the scope of set angle
According to；
5) processing that the data of the reservation reject error dot, to treated data along the axial direction of high-iron carriage
Direction is divided into the data point in several high-iron carriage sections by setting interval, is fitted respectively to the data point line in each section
At closed curve, the closed curve constitutes the envelope in the section, obtains all of high-iron carriage within the scope of set angle
Envelope；
6) the maximum Static Gauge as required high-iron carriage of size in all envelopes is taken.
In step 1), laser radar described in four is in the same plane.
In the scanning of step 3), the movement speed of four laser radars is identical.
Error dot described in step 5) is the exceptional data point due to caused by laser radar scanning mistake.
High-iron carriage Static Gauge measurement method based on laser radar of the invention has quick, accurate, versatility
By force, the big feature of measurement range can provide specific measured value, and commercial measurement and scientific research is facilitated to use.The present invention has
Following specific feature:
1, measurement is general: measurement method according to the present invention can measure the high-iron carriage of different model, as long as specification
High-iron carriage no more than gantry frame can be used.
2, the accuracy measured: the present invention uses high-precision laser radar, and the resolution ratio of radar can achieve 1mm, protects
The accuracy of the measuring system of card.
3, the safety measured: being measured as non-cpntact measurement, fierce machine does not occur with object under test in measurement process
Tool collision, will not damage compartment to be measured.
