To detect a recumbent pose, you should configure the frame perspective first.
To do this, do the following:
Set the size of the same person in different areas of the FOV. To create a leveling rod, left-click on the video image to add two anchor points. You should set at least three leveling rods. The size of the leveling rod should be about the average height of a person at this point in the frame. You can resize the rod by stretching its anchor points . You can move it on screen by dragging and dropping.
Attention!
When setting up the leveling rods, the following conditions should be met:
In complex scenes, it is recommended to add more than three rods to increase the accuracy of the detection.
In the parts of the frame where the lens vertical distortion is observed, the rods should be parallel to the nearest vertical objects (e.g. door, wardrobe).
If only three leveling rods are added to the scene, they cannot be removed from the scene, only their size and position can be changed.
If more than three leveling rods are added to the scene, you can change their position, size, and also remove them from the scene.
Attention!
For portrait-oriented scenes (such as corridor, shopping aisle, warehouse aisle, etc.), the arrangement of the rods should form triangles.
Note
For your convenience, you can click the button and configure the mask on a still frame. To undo, click this button again.
Note
To delete the rod, click the button.
Configuring the Man down detection tool is complete.
Attention!
In cases when the recumbent person is facing the camera or facing away from the camera, the correct operation of the detection tool isn't guaranteed.
