Construction waste identification method and construction waste sorting equipment

Abstract

The invention discloses a method for identifying construction waste, comprising: obtaining 2D images of construction waste, obtaining contours of each waste from the 2D image, and judging the material of the waste; obtaining X-ray images of construction waste, and analyzing X-ray images according to the area corresponding to the contour of the waste. The transmittance is used to judge the material of the garbage; the weighted calculation is performed on the judgment results of the previous steps to obtain the final material of the garbage. In addition, the present invention also discloses a kind of construction waste sorting equipment, which adopts the above-mentioned construction waste recognition method to identify recyclable waste and impurities, and its processing device also recognizes the position of each waste contained in the 2D image in the 2D image and recognizes the The position of the garbage whose material is impurities is sent to the robot, and the robot grabs the impurities at the real-time position of the conveying mechanism according to the position sent by the processing device and the construction waste sent by the encoder. The identification accuracy of impurities and recyclable garbage is high and will not harm the human body. cause excessive damage.

Description

Technical field [0001] The present invention relates to the identification of construction waste sorting techniques, and more particularly, to a method of construction waste and construction waste identification sorting equipment. Background technique [0002] In the process of construction waste, the chunks of brick, stone, concrete and other waste by crushing, sieving, the resulting aggregate can be widely used unburned brick, road infrastructure, construction and other industries. But may also contain a plastic, fabric, paper, rubber and other materials, these materials need an impurity chosen as construction waste, to improve the purity of the aggregate. [0003] Stage, the main impurity selected in two ways: a way, construction waste in the conveyor line, by manually picked plastic, fabric, paper, rubber and other materials, leaving bricks, stones, concrete and other recyclable aggregate material used to generate the multi-way labor intensive, inefficient, and the constructi...

AI Technical Summary

Problems solved by technology

[0003] At this stage, impurities are mainly selected through the following two methods: Method 1: On the conveying line of construction waste, materials such as plastics, fabrics, waste paper, and rubber are manually selected, leaving bricks, stones, concrete, etc. for recycling Materials are used to generate aggregates. This method is labor-intensive and inefficient, and construction dust can also cause harm to human health. Method 2 uses visual devices to identify impurities such as plastics, fabrics, waste paper, and rubber, and then uses robots to sort them out. Sorting out impurities, because construction waste is often covered with a lot of dust, it is easy to confuse impurities with recyclable materials such as stones and bricks through visual judgment, and it is impossible to accurately identify impurities
