Scenario Description

Application Limitations

• The LDU supports only target blocklists.
• When the function of authorizing intelligent target analysis is disabled for the HWT-IVS1800, the LDU does not support any operations on lists. The iClient S100 allows users to query and delete the device's lists, but does not allow users to add or modify lists.
• You are advised to import data records to the target list in batches. Note that in scenarios when 300,000 records are imported to the target list, the VA module of the system will be in peak hours for about 8 to 10 hours. To ensure that system resources are available, you are advised to import data to the target list in batches during off-peak hours.

Prerequisites

• You have enabled the target recognition function.

  For details, see Public Configurations.

• LDU
  • A removable disk (such as a removable hard disk or USB flash drive) that uses the FAT32, NTFS, or exFAT file system is available.

    To check the file system of a removable disk, perform the following steps:

    1. Insert the removable disk into the USB port of the computer.
    2. Right-click the removable disk and choose Properties from the shortcut menu.
    3. Click the General tab.
    4. Check whether the file system is FAT32, NTFS, or exFAT.
  • Target images have been named as required and stored on a removable disk (such as a removable hard disk or USB flash drive).
    • Batch import: Select a folder to upload the images in it. The images are named in Name_ID number_ID type_Gender_Nationality_Occupation format. Table 4-277 illustrates the naming format.
      A maximum of 16,000 target images can be stored in a single folder on a removable disk (such as a removable hard disk or USB flash drive) of the FAT32 or FAT file system. If more than 16,000 target images need to be imported, create multiple folders and import the images by folder.

      Table 4-277 Naming format requirements

      Naming Element	Description
      Name	Consists of 1–255 characters. Cannot start with a special character. Contains at least one of the following character types: Letters Digits Special characters including only space characters and hyphens (-)
      ID number	Consists of 1–255 characters. Contains at least one of the following character types: Letters Digits Special characters: ( )
      ID type	0: ID card 1: passport 2: student card 3: military ID card 4: driver's license 5: others
      Gender	0: male 1: female
      Nationality	Consists of 1–255 characters. Contains at least one of the following character types: Letters Digits Space characters
      Occupation	Consists of 1–255 characters. Contains at least one of the following character types: Letters Digits Space characters

    • Upload one by one: The image is named after the name.
    

    Target images in the target list must meet the following requirements:

    • Image format: Only .bmp, .dib, .jpe, .jpeg, .jpg, and .png images are supported.

    • Image size: The recommended image size is 35 KB to 200 KB. The size of a single image cannot exceed 720 KB.

    • Image quality: The target in the image must be clear. The image must be a grayscale image of eight bits or more.

    • Resolution: The recommended target resolution ranges from 80 x 80 to 200 x 200 pixels. The eye spacing must be greater than or equal to 60 pixels, ideally 90 pixels or more.

    • Brightness and contrast: The ambient illumination must be at least 300 lux. Use diffuse lighting for the best effect. The contrast should be moderate, and the face should not be shadowed. Avoid backlight and light reflection, and use a moderate exposure.

    • Posture: proper posture; look straight ahead; angle range: –10° to +10° (for yaw angles, pitch angles, and roll angles)

    • Occlusion: features (such as eyebrows, eyes, mouths, and noses): not covered by objects such as hair, masks, accessories, or glasses; glass lens: clear, colorless, and non-reflective (for the best effect)

    • Face: completely captured, well-defined, unretouched, and with light or no makeup

    • Countenance: neutral expression with eyes open and natural mouth gestures

    • Encoding requirement: The characters in target image names must be encoded in GBK or UTF-8 format. If the encoding format is not GBK or UTF-8, correct it. Target image names encoded in other formats will be displayed in garbled characters on the LDU.
• On the iClient S100, target lists are classified into two types: blocklist and trustlist. Table 4-278 describes the application scenarios and functions of these types of target lists.
  Table 4-278 Target list classification

  List Type	Application Scenario
  Blocklist	Used in scenarios such as swing gates, security gates, and straight-through pedestrian walkways. The system generates an alarm once a blocklisted target is detected.

Procedure (on the iClient S100)

• In versions earlier than V3.0.0, target list information can be synchronized from the iClient S100 to the HWT-IVS1800 but cannot be synchronized from the HWT-IVS1800 to the iClient S100.
• In V3.0.0 or later versions, if no plug-in is installed, target list information can be synchronized from the iClient S100 to the HWT-IVS1800 or from the HWT-IVS1800 to the iClient S100.

• In V3.0.0 or later versions, if the plug-in is installed, target list information can be synchronized from the iClient S100 to the HWT-IVS1800 but cannot be synchronized from the HWT-IVS1800 to the iClient S100.

1. Create a target list.
   1. On the iClient S100 home page, choose Maintenance Management > Video Device > Device List.
   2. Right-click an IVS1800 device and choose Target Library.
   3. On the list page, click + and create a target list, as shown in Figure 4-318. Click OK.
      Figure 4-318 Creating a target list
      
   4. Click New. The Add Target dialog box is displayed for you to add target information to the target list on the device, as shown in Figure 4-319.
      Figure 4-319 Add Target
      
   5. Upload a target image as required, enter target information, and click OK. The target information is successfully added to the target list and synchronized to the main device, as shown in Figure 4-320.
      Figure 4-320 Target information added to the list and synchronized to the main device successfully
      

Remarks

• Images in JPG format can be imported to the LDU, and features can be successfully extracted from such images. Some imported JPG images may fail to be displayed or may be displayed improperly on the LDU. However, the improperly displayed images can still be used for alert tasks.
• Images in JPG format can be imported to the iClient S100, and features can be successfully extracted from such images. Images in lists can be properly displayed on the iClient S100. Some imported JPG images may fail to be displayed or may be displayed improperly on the LDU. However, the improperly displayed images can still be used for alert tasks.

Procedure

1. Log in to the LDU as the admin user. ( Logging In to the LDU)
2. Right-click on the desktop and choose Intelligent Application > Library > Target List.
3. Check the feature extraction status of the target records.
   • Feature extracted: The target feature extraction has been completed and extracted features can be used for services such as target search.
   • Feature extracting: The target features are being extracted.
   • Failed to extract features: The target features cannot be extracted.
     • Ensure that the camera or HWT-IVS1800 has intelligent capabilities. For details about the scenarios requiring intelligent capabilities, see Feature Verification.
     • If the HWT-IVS1800 intelligent capability is used, ensure that the current services do not reach the upper limit of the service specifications. Otherwise, the feature extraction will fail.

       Assume that the current HWT-IVS1800 whose service specification is 4-channel target recognition at most, has been executing 4-channel target recognition tasks, if you add target records to the target list in this case, computing power is insufficient for extracting target features, causing feature extraction failure. In this scenario, you are advised to stop one channel of target recognition task and then extract target features. After target features are extracted, restart the target recognition task.

       Service specifications vary depending on device models. For details, see Product Specifications.
