The mortar projectiles often land on the back of the hillside when fighting in mountainous areas. The projectile hits the target with a small landing angle, and there will be a phenomenon of rubbing the ground, resulting in a low hit rate. In this paper, a multi-rigid-body dynamics virtual prototype model is established for different targets struck by a different falling angle of the mortar projectile, the displacement and velocity data of the firing-pin and detonator as well as the incomplete firing results are obtained through simulation, the firing probability is evaluated by applying the Monte Carlo method, the contribution of the variables affecting the target value is obtained by applying the design of experiment (DOE), and the relevant parameters are optimized to realize fully fire when the parameters are in their new value range.
Two image sensors simulate directly the way of disposing images with the human's two eyes, so it has important
value to apply to many domains, such as object identify, workpiece localization, robot navigation, and so on. This paper
focus on the object localization and distance detection based on two image sensors. It concentrates on how to apply two
CCD image sensors to object localization of a sphere in indoor environments. At first a space model of the two image
sensors was set up, then an experiment platform was built in order to prove the correctness and feasibility of that
localization algorithm, and the relationship between the coordinate localization accuracy and the sensor structural
parameters was analyzed. At the end the source caused to localization errors was found out by their characteristics.
