1. A drive assist device comprising:

  • an overhead image generating unit that generates a vehicle periphery overhead image as a display image of the periphery of a vehicle displayed in a monitor, by performing viewpoint conversion from a captured image obtained by a camera that captures the periphery of the vehicle;

    a steering angle calculation unit that calculates a steering angle of the vehicle;

    a forward trajectory setting unit that sets a forward trajectory serving as an expected trajectory in the travel direction of the vehicle when turning based on the calculated steering angle calculated by the steering angle calculation unit;

    a reverse trajectory setting unit that sets a reverse trajectory serving as an expected trajectory in the travel direction of the vehicle or the opposite direction as the travel direction of the vehicle when turning based on a steering angle in the opposite direction as the calculated steering angle; and

    an image synthesizing unit that generates a drive assist overhead image for display in a monitor by synthesizing the forward trajectory and the reverse trajectory with the vehicle periphery overhead image, so that a vehicle image in the vehicle periphery overhead image serves as a departure point.
