Can SpatialImgDetections messages have conf values with each det?

AdamPolak

I am using this model: https://docs.openvino.ai/2022.3/omz_models_model_person_detection_retail_0013.html

And from the documentation here: https://docs.luxonis.com/projects/api/en/latest/components/nodes/mobilenet_spatial_detection_network.rst/

propertyout

Outputs ImgDetections message that carries parsed detection results.

It seems like the node is able to use the parsed detection results. Is there a way to combine the confidence threshold on the individual detection so it is received at the host with an associated confidence threshold?

Hi AdamPolak
You can, here are docs for SpatialImgDetections (output of the node):
https://docs.luxonis.com/projects/api/en/latest/references/cpp/#classdai_1_1SpatialImgDetections

So SpatialImgDetections has detections, list of SpatialImgDetection, which has:

Point3f spatialCoordinates;
SpatialLocationCalculatorConfigData boundingBoxMapping;
uint32_t label = 0;
float confidence = 0.f;
float xmin = 0.f;
float ymin = 0.f;
float xmax = 0.f;
float ymax = 0.f;

erik Sorry about that, been looking at the top section of docs, wasn't checking out the bottom.
