The inference results are provided in the eCAL topic traffic_sign_detection as JSON data. The following example show how an object could look like:
{
"iso_timestamp": "2024-11-04T12:50:48.697684",
// Class labels for each detected traffic sign
"class_ids": [
22.0, // info_crosswalk
40.0 // priority_stop
],
// Confidence scores for detected traffic sign
"confidences": [
0.7705173492431641, // confidence info_crosswalk
0.29842549562454224 // confidence priority_stop
]
