Application Scenario Illustration
1. Auto-focusing function should not been enabled for line crossing detection. If enabled, the
video image will change so greatly that the algorithm will stop working temporarily.
2. Try not to enable line crossing detection when light changes greatly in the scene.
3. Try to install the camera at a certain angle of depression.
4. Adequate light and clear scenery are very important to line crossing detection.
5. Adjust the camera to make the detection area in the center of the video image. Make sure
no obstructions are in the main crossing area. It is strongly recommended to make the
obstructions (like trees, bushes, flags, etc.) outside the detection area.
6. Please contact us for more detailed application scenarios.
Here we take some improper application scenarios for instance.
