Abstract
A floor height detection method is applied to a surveillance camera, and a surveillance image captured by the surveillance camera contains a surveillance region. The floor height detection method includes dividing the surveillance image at least into a first region and a second region, acquiring an actual installing height matrix of the surveillance camera upon the first region and the second region, and utilizing a matrix factorization algorithm to analyze the actual installing height matrix to acquire floor heights within the surveillance region.
Claims18
A floor height detection method applied to a surveillance camera, a surveillance image captured by the surveillance camera containing a surveillance region, the floor height detection method comprising:
- dividing the surveillance image at least into a first region and a second region;
- acquiring an installing height matrix of the surveillance camera upon the first region and the second region;
- and
- utilizing a matrix factorization algorithm to analyze the installing height matrix for acquiring floor heights of the surveillance region, so as to determine whether to divide the first region or the second region in accordance with the floor heights.
A surveillance camera, comprising:
- an image receiver adapted to receive a surveillance image containing a surveillance region;
- and
- an operation processor electrically connected to the image receiver in a wire manner or in a wireless manner, and adapted to analyze the surveillance image, so as to divide the surveillance image at least into a first region and a second region, acquire an installing height matrix of the surveillance camera upon the first region and the second region, and utilize a matrix factorization algorithm to analyze the installing height matrix for acquiring floor heights of the surveillance region, so as to determine whether to divide the first region or the second region in accordance with the floor heights.
