Sagger flatness detection device based on binocular structured light and detection method thereof

Abstract

The invention discloses a sagger flatness detection device based on a binocular structured light and a detection method thereof. The device comprises a binocular structured light camera, a three-dimensional point cloud reconstruction module, a fitting plane module and a sagger flatness detection module; the binocular structured light camera is connected with the three-dimensional point cloud reconstruction module, the three-dimensional point cloud reconstruction module is connected with the fitting plane module, and the fitting plane module is connected with the sagger flatness detection module; the fitting plane module is connected with the sagger flatness detection module, and the binocular structured light camera is used for projecting infrared coded structured light to a sagger to be detected and collecting a binocular sagger coded image with coded information; the three-dimensional point cloud reconstruction module is used for calculating depth information of the binocular saggercoded image and reconstructing three-dimensional point cloud data of a sagger distance binocular structured light camera by utilizing the depth information; the fitting plane module is used for fitting a plane as a reference plane by adopting a plane fitting method according to the three-dimensional point cloud data; and the sagger flatness detection module is used for judging the flatness of thesagger according to the projection distance information set from the three-dimensional point cloud data to the fitting plane.

Description

Technical field[0001]The invention relates to a saggar flatness detection, in particular to a saggar flatness detection device based on binocular structured light and a detection method thereof.Background technique[0002]A sagger is a kind of kiln furniture made of refractory materials, which is used to contain reaction materials in the production of electrode materials. In the existing production process, the electrode calcination temperature is high, and some raw materials are highly corrosive during the reaction. The sagger needs to withstand higher thermal stress and corrosion of the reaction materials, resulting in uneven pits and rough undulations in the sagger Of small pieces. Damaged saggers can easily fall off their own powder, causing pollution of the raw materials it contains, seriously affecting product quality and causing additional economic losses to the enterprise.[0003]At present, the flatness of saggars on the market is generally inspected manually.

Problems solved by technology

In the existing production process, the calcination temperature of the electrode is high, and some raw materials are highly corrosive during the reaction process, and the sagger needs to withstand high thermal stress and corrosion of the reaction material, resulting in uneven small pits and rough undulations in the sagger small piece of

Damaged saggars are easy to fall off their own powder, causing pollution of raw materials, seriously affecting product quality, and bringing additional economic losses to the enterprise

[0003] At present, the flatness of saggers on the market is generally checked manually, and it is easy to cause fatigue after long-term observation, so there will be problems such as misjudgment and missed judgment.

Missed judgments lead to the generation of defective products, while misjudgments will cause waste

At the same time, the sagger is relatively heavy, and manual inspection is time-consuming and laborious, which needs to be improved urgently
