Abstract

A rail vehicle system, a rail vehicle, and a visual sensing device are provided. The rail vehicle system includes a system control device, a rail, and a rail vehicle. The rail vehicle includes a processing device and the visual sensing device. In a process where the rail vehicle travels along the rail, the visual sensing device captures images in front of the rail vehicle, and the visual sensing device emits a laser beam toward a front side of the rail vehicle. The visual sensing device receives the reflected laser beam to generate a laser sensing data. The processing device determines whether or not to change at least one of a travel direction and a travel speed of the rail vehicle according to the images captured by the visual sensing device and the laser sensing data.
