Abstract

The invention relates to a rugged road surface detection method and device, a storage medium, electronic equipment and a vehicle, belongs to the field of vehicles, greatly reduces the calculation amount, and is high in detection precision. The rugged road surface detection method comprises the steps of acquiring a first type of image and a second type of image about the same road surface, whereinthe first type of image is a color and / or brightness image, and the second type of image is a depth image; extracting first road surface information according to the first type of images; according toan interleaving mapping relationship between the first type of images and the second type of images, performing equal-proportion adjustment on the first road surface information to obtain second roadsurface information corresponding to the first road surface information in the second type of images; and determining rugged road surface information according to the first road surface information in the first type of images and the second road surface information in the second type of images.

Description

technical field [0001] The present disclosure relates to the field of vehicles, and in particular, to a rough road detection method, device, storage medium, electronic equipment, and vehicle. Background technique [0002] Existing rough road detection methods include: collecting sampling values ​​from vibration-sensitive signals, statistical modules to filter out periodic anomalies and random anomalies and calculate statistical signals, and then calculate the first-order and second-order derivatives based on velocity or time through the differential module, Finally, the presence of rough road conditions is determined by a comparison module based on statistical signals or first and second derivatives. [0003] Since the existing detection methods mainly use vibration sensitive signals to sample and obtain rough road information through a series of calculations and comparisons, the calculation difficulty is high and the accuracy is low. Contents of the invention [0004] Th...
