mxpi_motsimplesortV2

Tracks movement of multiple objects (motor vehicles, non-human objects, and individuals). The differences between this version and the previous version are as follows:

• In the V2 version, the input port of the plugin is adjusted. When only the bounding box information of an object is used for Multiple Object Tracking (MOT), only one input port needs to be connected. On this basis, if the characteristics of the object are further used for MOT, two input ports are connected.
• dataSource implements automatic configuration.

• Input: buffer (data type: MxpiBuffer), metadata (data type: MxpiObjectList)
• Output: buffer (data type: MxpiBuffer), metadata (data type: MxpiTrackLetList)

• Static input: {"ANY"}; dynamic input: {"ANY"}
• Static output: {"ANY"}

For details, see Table 1.

dataSourceDetection

Index of the bounding box data after model detection. The default value is the key value of the output port of the upstream plugin.

No

Yes

dataSourceFeature

Index of the object feature data after feature extraction. The default value is the key value of the output port of the upstream plugin.

No

Yes

trackThreshold

Threshold for the probability that the traced objects are the same. If the probability is greater than the threshold, the traced objects are the same. The value range is [0, 1.0], and defaults to 0.5.

No

Yes

lostThreshold

Threshold for the number of lost frames of a traced object. If the number of lost frames is greater than the threshold, the traced object is lost. The value range is [0, 10], and defaults to 5.

No

Yes
