The invention discloses an object size estimation system and method, a warehouse capacity estimation system and method and a computer readable storage medium. The object size estimation system comprises a to-be-tested object, an object bearing device, the object bearing device being used for bearing to-be-tested goods, a first support, the first support being provided with a shooting device used for shooting a depth image and a color image, and an estimation module used for estimating the size of the to-be-measured object. According to the object size estimation system, the shooting device isarranged to obtain the depth information and the information, so that whether the object exists or not can be determined, the existence range of the object can be determined, and the size of the goodscan be estimated; the method can automatically calculate the size of the object without manual measurement, and is low in cost and high in efficiency.

The invention discloses a laser marking method for a random three-dimensional code, and belongs to the field of laser processing. The laser marking method comprises the following steps: changing a black region of a two-dimensional code image into a color to generate a three-dimensional code color image; generating marking paths according to the three-dimensional code color image, and classifying the marking paths according to colors to obtain classified storage information; and marking a random three-dimensional code on the multi-layer anti-counterfeiting module by adopting a laser according to the classified storage information, wherein the multi-layer anti-counterfeiting module is formed by superposing materials with different colors, and the colors of the materials include the color types in the three-dimensional code color image. According to the invention, the marking time is fixed; and the output power of the laser is modulated according to the received classified storage information, or when the output power of the laser is fixed, the marking time is adjusted according to the received classified storage information, and three-dimensional codes with different depths and a concave-convex feeling can be quickly marked on the multi-layer anti-counterfeiting module after one processing path is completed, so that the processing efficiency is greatly improved.

The invention provides a multi-stage denoising system and method for a color image. The multi-stage denoising system comprises a channel separation module, an intra-channel denoising network and an inter-channel denoising network, wherein the channel separation module is used for separating the color image with noise into original noise images of a plurality of channels; the intra-channel denoising network is used for carrying out preliminary denoising on an original noise image; and the inter-channel de-noising network is used for further de-noising according to the preliminary de-noising result and the original noise image to obtain a clean image. In specific implementation, a denoising task is divided into two stages: denoising in an image channel is carried out by utilizing spatial dimension information in a single channel, and then inter-channel denoising is further carried out by utilizing associated information between channels; meanwhile, when denoising processing is carried out, an error feedback mechanism is added to an up-sampling part and a down-sampling part, and the denoising effect is enhanced.
