Image retrieval through a multibeam imaging sonar

Question

I would like to know if anyone here has used the Blueview SDK (Linux) for retrieval of images from the pings obtained by a multibeam sonar (P450, P900, etc.) ? If so, I'd like to know why would anyone get a null head when I trying to retrieve the head (eventually for the pings to be converted to an image) using the BVT_GetHead() method. My snippet for retrieving the image from a .son file (some_son_data.son) is given below:

int main() {
    BVTSonar son = BVTSonar_Create();
    BVTSonar_Open(son, "FILE", "some_son_data.son");

    if (NULL != son) cout << "son not null" << endl;
    BVTHead head = NULL ;
    BVTSonar_GetHead(son, 0, &head);
    return 0;
}

Answer 1

We are using the P900 multibeam sonar.

So far our interface hasn't any problem. But we requested a new version of the library from teledyne which works now in our case.

sonar = new BVTSDK::Sonar();
head = new BVTSDK::Head();
int ret = sonar->Open("NET", hostAddress);
 //error handling
ret = sonar->GetHead(1, head);
//again error handling

I will ask wether we can publish our interface within the next weeks.
