The invention discloses an optimized layout method of roadside structured light cameras supporting automatic driving. The method mainly comprises the following steps: step 1, data acquisition and processing; step 2, establishing an objective function; and step 3, solving the optimal position of the structured light camera through a random optimization algorithm. According to the method, perception performance evaluation indexes of a roadside perception system composed of a plurality of roadside structured light cameras can be measured according to the layout positions and orientations of the roadside structured light cameras, and the layout positions of the structured light cameras enabling the perception indexes of the perception system to be optimal can be found by applying a random optimization algorithm; it is ensured that the sensing precision and the coverage area of the road section reach the level meeting the conditions, high-accuracy digital twinning is constructed, and the method has very high practical significance for safe operation of automatic driving.
