  • Publication number: 20240092662
    Abstract: A method for removing a heavy metal from water includes subjecting a microbial solution containing a liquid culture of a urease-producing bacterial strain and a reaction solution containing a manganese compound and urea to a microbial-induced precipitation reaction, so as to obtain biomineralized manganese carbonate (MnCO3) particles, admixing the biomineralized MnCO3 particles with water containing a heavy metal, so that the biomineralized MnCO3 particles adsorb the heavy metal in the water to form a precipitate, and removing the precipitate from the water.

  • Patent number: 11418771
    Abstract: A method for calibrating a 3D camera includes arranging a 3D object and a background with contrast color on surfaces, and capturing the 3D object to get an image by a 2D camera and capturing a point cloud by the 3D camera in a one-pass operation. The raw colors of the 3D object and the background of the point cloud are separated and recorded. The point cloud of the 3D object and the background are transformed into the position of the corresponding pixel in the image to get transformed colors. The missing score is computed based on color changes of the point cloud. The transform parameter transforming the coordinate systems of the cameras is optimized to reduce the missing score, so as to quickly calibrate the 3D camera.

  • Patent number: 10786901
    Abstract: A method for programming a robot in a vision base coordinate is provided. The method includes the following steps. A robot is drawn to an operation point. The coordinates of the operation point in a photo operation are set as a new point. A teaching image is captured and a vision base coordinate system is established. A new point is added according to the newly established vision base coordinate system. When the robot is operating, the robot is controlled to capture an image from a photo operation point. A comparison between the captured image and a teaching image is made. The image being the same as the teaching image is searched according to the comparison result. Whether the vision base coordinate system maintains the same corresponding relation as in the teaching process is checked. Thus, the robot can be precisely controlled.
