This invention provides a multi-sensor obstacle recognition method, system, and terminal for lawnmower robots. The lawnmower integrates a visual sensor and a time-of-flight (TOF) sensor. By acquiring images and TOF data, the system processes the images and extracts a mask for the grass region. Then, based on the images and TOF data, point cloud partitioning and grass height estimation are performed. Combined with the grass region mask, accurate obstacle recognition is achieved. This method combines the advantages of visual and TOF sensing technologies to construct a more robust and efficient obstacle recognition system, significantly improving the lawnmower robot's adaptability in complex environments and ensuring its operational safety. This invention effectively reduces the limitations of lawnmower usage, significantly reduces the missed and false detections of small obstacles due to grass obstruction, and avoids misidentifying tall grass and weeds as obstacles, thereby significantly improving the accuracy of obstacle recognition.

This invention belongs to the field of calcium carbonate processing technology, specifically a carbonation tower for processing nano-calcium carbonate. It includes a U-shaped base; a tower body located within the opening of the U-shaped base; a complex mixing device mounted on the U-shaped base; the complex mixing device includes rotating shafts installed on opposite sides of the U-shaped base; the opposite ends of the two rotating shafts are connected to the outer wall of the tower body; a pressure-bearing circular plate located inside the U-shaped base; the pressure-bearing circular plate is located at the bottom of the tower body, and the two are in contact; and a pressure-relieving and energy-delaying mechanism is mounted on the pressure-bearing circular plate. This allows the gas and liquid to continuously oscillate left and right within the tower body, constantly dispersing their distribution, avoiding dead zones during stirring, and preventing material agglomeration and density stratification. The constantly changing positions of the gas and liquid within the tower body facilitate stirring and enhance gas-liquid contact, not only improving the production quality of calcium carbonate but also further reducing the application limitations of the carbonation tower.
