Embodiment Construction

[0017] The device is fixed on the bracket of the mobile multi-dimensional image acquisition system, and the camera is fully automatically calibrated without any human operation. During implementation, wait for the diffuse reflection protective cover to open automatically, place the barium sulfate diffuse reflection coating horizontally towards the camera, and collect images of the diffuse reflection plate during the opening time period, and calibrate the camera according to the spectral correction algorithm, and after 10 minutes, the diffuse reflection plate Self-closing, in a state of protection, for maximum protection of its life and precision.

[0018] The present invention will provide technical support for the automatic correction and protection of the diffuse reflection plate. The operation of the diffuse reflection plate will no longer rely solely on manual operation, and the functions of automatic opening and closing, automatic dust removal and the like will solve the p...

Abstract

The invention discloses an intelligent protective type diffuse reflection reference plate. The device is a multispectral diffuse reflection plate with an automatic protection function. The multispectral diffuse reflection plate is composed of an autorotation inserted link, a spin protective cover, a diffuse reflection tray, a diffuse reflection coating and an automatic control module. A stepping motor drives the autorotation inserted link to rotate, thus finishing up-down flip of the diffuse reflection tray. By self-spinning of the spin protective cover, automatic opening and closing of the diffuse reflection protective cover are completed. The diffuse reflection coating is barium sulfate powder, mixed water and white latex (polyvinyl acetate adhesive) which are uniformly sprayed into the fluted diffuse reflection tray by a high-pressure spray gun. The diffuse reflection tray and the spin protective cover are both made of an aluminium material and undergo sand conditioning with acid liquor. The device is designed for automatic spectral monitoring in a complex field environment. The diffuse reflection coating can be protected to the greatest extent so as to prolong service life of the diffuse reflection coating and its enhance precision.

Description

technical field [0001] The invention belongs to a multi-spectral diffuse reflection reference device, which is applicable to complex test environments and supports automatic control. Background technique [0002] Diffuse reflectance reference plates are mostly used for spectral calibration of optical instruments. Most of the existing diffuse reflection reference plates are composed of a diffuse reflection working surface, a bottom plate, a supporting plate, and a protective cover. The supporting plate is in the shape of a groove and can be seamlessly closed with the protective cover. The base plate is made of vinyl fluoride, and the bottom plate is embedded in the supporting plate. Because of the good diffuse reflection characteristics of aluminum, aluminum-plastic plate or aluminum plate is often used as the bottom plate. , or use paint made of magnesium oxide, barium sulfate, etc., to spray on the bottom plate as a diffuse reflection working surface. [0003] Most of the...
