Dear Dear Sir or Madam,
I got some troubles with the 'security_barrier_camera_demo' while I am modifying some.
I am trying to change the license plate character recognition model to my own model.
My concern is that how to get correct output data with my own xml file.
<My own xml file>
<layer id="47" name="189/reshape_back" precision="FP32" type="Reshape">
<input>
<port id="0">
<dim>1</dim>
<dim>215</dim>
<dim>1</dim>
<dim>32</dim>
</port>
<port id="1">
<dim>3</dim>
</port>
</input>
<output>
<port id="2">
<dim>1</dim>
<dim>215</dim>
<dim>32</dim>
</port>
</output>
</layer>
...
...
<edge from-layer="46" from-port="1" to-layer="47" to-port="1"/>
There was some clues in 'getResults' function of 'class Lpr' in 'security_barrier_camera_demo/net_wrappers.hpp' file.
The original output data should follow the rules in 'license-plate-recognition-barrier-0001.xml'.
And I have no idea how to get the output data with my own model.
Sincerely,
JS
<'security_barrier_camera_demo/net_wrappers.hpp'>
std::string result;
result.reserve(14u + 6u); // the longest province name + 6 plate signs
// up to 88 items per license plate, ended with "-1"
const auto data = inferRequest.GetBlob(LprOutputName)->buffer().as<float*>();
for (int i = 0; i < maxSequenceSizePerPlate; i++) {
if (data == -1) {
break;
}
result += items[static_cast<std::vector<std::string>::size_type>(data)];
}
return result;
