| Abstract: | In this paper, according to the digital correlation of computer image process, a new high precision and un-tounched method for measuring the large quantifier distance was presented. In factual application, this method is used for measuring the distance of CJ6120LC6HK carriage front and trailing wheel-base. The analysis of the correlation function, measuring precision and measuring error were described. Based on the 1m high precision mir, the accurate orientation has been given, so that the good results has been obtained for measuring the distance of CJ6120LC6HK carriage front and trailing wheelbase. In conclusion, the method for measuring the large quantifier distance could give a revelation to the engineering application. |
