[0040] The specific implementation manner and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0041] Such as figure 2 As shown in , an accurate registration method of damaged parts based on the improved ICP algorithm is carried out according to the following steps:
[0042] First enter step 1: get the original model point set Q 0 and damage model point set P 0 , denoted as Q 0 ={q j0 |j=1,2,...,m} and P 0 ={p i0 |,i=1,2,…,n}, using the three-point alignment method, the original model point set Q 0 As a reference, for the damage model point set P 0 Perform pre-registration to obtain the damage model point set P after the k=1th iteration k ,in, is the original model point set Q 0 The three-dimensional coordinate position of the jth point in , is the damage model point set P 0 The three-dimensional coordinate position of the i-th point in , is the damage model point set P afte...
