[0032] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0033] The present invention provides a method for estimating depth levels based on single-frame images, which is a simple and easy-to-operate method for estimating depth of field in daytime scenes, without relying on complex samples and pixel classifiers, and is an end-to-end image processing algorithm. While achieving good estimation results, it can greatly reduce the amount of calculation, and is suitable for running on embedded platforms, drones and other application scenarios. Based on the related theory of dark channel, a simple and easy-to-implement method for image depth level estimation is deduced.
[0034] The farthest visible point detection method based on a single frame image of the present invention is as follows: figure 1 shown, follow the steps below:
[0035] Step 1: Calculate the dark channel image of the image. The dark cha...
