· You can rename the saved CNN file before uploading to change the display name (requires IDS NXT OS 1.1 or later and IDS NXT cockpit version 2.1 or later). Detection threshold Here, you set the value as of when a detection should be evaluated as a valid result. Note that a value too low might lead to false detections. -

Fig. 4: Upload a CNN package Here, you upload a CNN file (*.det) that you have trained previously, e.g. in IDS NXT lighthouse for object detection. After successfully uploading the CNN file, you can select the CNN in the settings. Object Detector can use CNNs for object detection created for IDS NXT OS 1.1 or higher... -
