To ensure the correct recognition of a person's posture, the following image requirements should be met:
The minimum value of pixel density per meter is observed:
Image resolution | Object type | Minimum pixel density per meter (ratio of the object width in pixels to the object width in meters) | Minimum object size in pixels, width x height |
---|---|---|---|
