SD3403|SS928 LDC畸变矫正错误_问答

我在vpss中使用GDC模块的LDC V2进行畸变矫正，使用QPTool得到畸变参数，然后

使用pqtool工具加载拍摄方格版的图片，获取LDC V2的参数

在使用ss_mpi_vpss_set_chn_ldc_attr()设置矫正属性的时候会报错
[func]:ot_mpi_vpss_set_chn_ldc_attr [line]:1021 [info]:grp0 chn2 set ldc attr to VPP failed!
错误码0xa007800c

使用的代码如下

ret = ss_mpi_vpss_get_chn_ldc_attr(0, 2, &ldc_attr);
if(ret != TD_SUCCESS){
LOG_ERROR("get ldc attr fail for %#x!", ret);
return HI_FAILURE;
}
