Some parameters can be bulk configured for Scene Analytics detection tools simultaneously. To configure them, do as follows:
Select the Object tracker object.
By default, video stream 's metadata are recorded in to the database. You can disable it the recording by selecting selecting No in the Record objects tracking list (1).
Note title Attention! Video decompression and analysis are used to obtain metadata, which causes high Server load and limits the number of video cameras that can be used on it.
If a the video camera supports multistreaming, select the stream for which detection is needed (2). Selecting a low-quality video stream allows reducing the load on the Server.
Note title Attention! To display the object trajectories tracks properly, make sure that all video streams from multi-streaming multistreaming camera have the same aspect ratio settings.
If you require automatic adjustment of need to automatically adjust the sensitivity of the scene analytic detection tools, select Yes in the Auto sensitivity list , select Yes (3).
Info title Note Enabling It is recommended to enable this option is recommended if the lighting fluctuates significantly in the course of the video camera 's operation (for example, in outdoor conditions).
To reduce the number of false alarms rate positives from a fish-eye camera, you have to position it properly (4). For other devices, this parameter is not valid.
- Select a processing resource for decoding video streams (5). When you select a GPU, a stand-alone graphics card takes priority (when decoding with NVIDIA NVDEC chips). If there 's is no appropriate GPU, the decoding will use the Intel Quick Sync Video technology. Otherwise, CPU resources will be used for decoding.
- In the Motion detection sensitivity field (6), set the sensitivity for motion of the scene analytics detection tools , on a scale of 1 to 100to motion in the range [1, 100].
- To correct for smooth camera shake, set Antishaker to Yes set Yes for the Antishaker parameter (7). This setting parameter is recommended only for cameras that show clear signs of shaking-related image degradationto use only when the camera shake is evident.
Analyzed framed are scaled down to a specified resolution (8, 1280 pixels on the longer side). This is how it works:
If the longer side of the source image exceeds the value specified in the Frame size change field, it is divided by two.
If the resulting resolution falls below the specified value, it is used further.
If the resulting resolution still exceeds the specified limit, it is divided by two, etc.
Info title Note For example, the source image resolution is 2048*1536, and the
limitspecified value is set to 1000.
In this case, the source resolution will be
dividedhalved two times (
down to512*384)
:, as after the first division, the number of pixels on the longer side exceeds the limit (1024 > 1000).
Info title Note If detection is performed on a higher resolution stream and detection errors occur, it is recommended to reduce the compression.
- Enter the time interval in seconds, during which which object 's properties will be stored in the the Time of object in DB field (9). If the object leaves and enters the FOV within the specified time, it will be identified as one and the same object (same ID).
If necessary, configure the neural network filter (see Hardware requirements for neural analytics operation). The neural network filter processes the results of the tracker and filters out false alarms positives on complex video images (foliage, glare, etc.).
Note title Attention! A neural network filter can be used either for analyzing moving objects, or for analyzing abandoned objects only. You cannot operate two neural networks simultaneously.
Enable the filter by selecting Yes (1).
Select the processor for the neural network – CPU, one of GPUs or a IntelNCS, or one of Intel GPUs (2). , see Hardware requirements for neural analytics operation, General Information on Configuring Detection).
Tip Note title Attention! It may take several minutes to launch the algorithm on an NVIDIA GPU after you apply the settings.
- Select a neural network (3). To access a neural network, contact AxxonSoft technical support. If no neural network file is specified, or the settings are incorrect, no filtering will occur.
Note A neural network filter can be used either only for analyzing moving objects, or only for analyzing abandoned objects. You cannot operate two neural networks simultaneouslytitle Attention! - the filter will not operate.
- Click the Apply button.
The general parameters of the situation analysis Scene Analytics detection tools are now set.
