Abstract: An information interaction method and apparatus, an electronic device and a storage medium are provided, the method comprising: displaying a preset first special effect element in a virtual reality space; determining whether a spatial relationship between a target control part controlled by a user and displayed in the virtual reality space and the first special effect element meets a preset condition; and in response to determining that the preset condition is met, displaying a second special effect associated with the first special effect element.

Abstract: The present invention proposes a method for rapidly dehazing an underground pipeline image based on dark channel prior (DCP). The method includes: preprocessing a hazy underground pipeline image to obtain a dark channel image corresponding to the hazy image; average-filtering the obtained dark channel image to estimate an image transmittance; compensating an offset value for an average filtering result to obtain a rough estimate of the transmittance; using a pixel value of the original image and an average-filtered image to estimate a global atmospheric light value; and using a physical restoration model to restore a dehazed image. The method of the present invention realizes the timeliness of the algorithm while ensuring the dehazing effect, and is suitable for scientific fields such as video monitoring of underground pipeline environment and identification of underground pipeline defects.
