Abstract: A target detection method based on fusion of vision, lidar and millimeter wave radar comprises: obtaining original data detected by a camera, a millimeter wave radar, and a lidar, and synchronizing the millimeter wave radar, the lidar, and the camera in time and space; performing a calculation on the original data detected by the millimeter wave radar according to a radar protocol; generating a region of interest by using a position, a speed, and a radar reflection area obtained from the calculation; extracting feature maps of a point cloud bird's-eye view and the original data detected by the camera; projecting the region of interest onto the feature maps of the point cloud bird's-eye view and the original data detected by the camera; fusing the feature maps of the point cloud bird's-eye view and the original data detected by the camera, and processing a fused image through a fully connected layer.

Abstract: Disclosed is a power-adjustable wave power generator, comprising a support platform (1), a power generator (2), a rotary shaft (3), an impeller rod (4), a blade frame (6), blades (7), a synchronous movement mechanism and a lifting mechanism. The power generator (2) is arranged on the support platform (1) and connected to the support platform (1). The impeller rod (4) is radially connected to the rotary shaft (3). The blade frame (6), which is provided with several blades (7), is slidably connected to the impeller rod (4). The synchronous movement mechanism adjusts the distance of the frame (6) relative to the rotary shaft (3). The lifting mechanism adjusts the angle of the blades. The power generator can not only effectively generate power under the condition of small waves, but also can adjust extracted energy according to a full load of power generation when a wave force remains unchanged, and can automatically prevent a disaster under the condition of a catastrophic climate.
