The following table describes the elements of the LPR IntelliVisionIV module object object settings panel.
№ | Parameter name | Parameter setting method | Description | Data type | Default value | Value range |
|---|
1
| Performance group |
| Use GPU checkbox | Check the box | Enables the use of GPU (graphics processing unit) computing resources to improve the license plate recognition performance | - | No | |
- - − the GPU computing resources are used to increase the performance of license plate recognition.
- Checkbox is not
|
set - - set − the CPU (central processing unit) computing resources are used.
|
2 | Accuracy drop-down list | Selecting the value in the list | Selecting the numbers recognition accuracy | List | Maximum | - Maximum
|
- - − enables maximum recognition accuracy, but it causes great CPU and/or GPU load.
- High
|
- enables - − enables high recognition accuracy, it requires
|
less computing - less computing resources than for maximum accuracy.
- Fast
|
- - − enables high recognition speed, but the accuracy becomes worse

Strategy drop-down list | Selecting the value in the list | Selecting the computing resources use mode | List | System |
Process - - Process − mild mode: no more than 1 core for 1 license plate.
- System
|
- - − default mode: all available computing cores are in use
|
;Core - - Core − strict mode: 1 core per stream
|
.4Platform drop-down list | Selecting the value in the list | Selecting the device on which the module will operate | List | CPU | |
