The invention relates to a vehicle speed detecting device and method. The vehicle speed detecting device comprises a laser rangefinder and a processor. The laser rangefinder scans in a direction forming a preset included angle with the driving direction of a vehicle, and transmits the scanning information to the processor. The processor processes the received scanning information to obtain and store all the occupied regions of the vehicle, and calculates the corresponding vehicle speed based on the occupied regions, the corresponding scanning time and the preset included angle. The invention achieves automatic and accurate detection of the vehicle speed by using the laser rangefinder, and has the advantages of simple detection, high convenience and low cost.
