A non-spherical projection display structure and system that can be optimized for the ergonomics of preferably one viewer inside the display structure or system. The structure or system is preferably for use with widescreen projectors. The non-spherical projection display structure and system creates a visual projection display and method of operating the display that has a wide horizontal and vertical field of view and uses a rear projected display structure having a projection screen surface with a thickness. The display structure has at least one section with a monotonically increasing or decreasing radius of curvature.

A display structure with a dimming module, and a biasing dimming module and a parallel plate dimming module thereof are provided. The display structure includes a visual projection display module provided with an ambient-light-contact end and a dimming module disposed between the ambient-light-contact end and ambient light. Thus the ambient light transmitted through the visual projection display module and used as backlight is controlled effectively by the display structure for providing the best vision.

The invention discloses a semi-automatic parking system, comprising: a vehicle body positioning unit for simulating the shape of the vehicle body, measuring the distance between the vehicle body and surrounding obstacles, and simulating the surrounding environment of the vehicle body according to the distance; a display unit for The vehicle body shape simulated by the vehicle door positioning unit and the surrounding environment form a visual projection; the vehicle body control unit is used to judge whether to brake the vehicle body according to the distance measured by the vehicle body positioning unit. Use the door positioning unit to simulate the body and the surrounding environment, and transmit the projection to the customer through the display unit. When the driver reverses the car through the observation projection, it is equivalent to standing outside the car. The viewing angle of the traditional reversing image is more comprehensive. The invention also discloses a car and a parking method using the above-mentioned semi-automatic parking system.

The invention provides a humanoid robot throwing and stability control method based on vision and movement. By means of the combination of vision, movement and operation, the operation requirement for throwing a target object through a robot is met, throwing the object through the robot is equivalent to exerting corresponding impact force and rotating torque on the gravity of the robot, and the stability of the robot after throwing the object is kept by adjusting the joint driving force of the robot or a stepping mode of the lower limbs. The method of throwing the object through the humanoid robot based on vision, movement, operation and stability is designed, the operational capacity of the robot can be enhanced, and the number of application occasions of the humanoid robot is increased.

The invention relates to an entry mode of pictures of a three-dimensional large scene. According to the mode, a group of positioning points is selected as positioning end points; projection coordinates are moved to the positioning end points along the spatial axial direction of a three-dimensional model; and the fusion and the transition of the three-dimensional images and panoramic pictures are realized in the moving process. The mode has the beneficial effects that in the moving process, the connection of two dimension and three dimension is realized through the fusion of the three-dimensional images and the panoramic images; in the process of entering or flying out of roaming, an observer is in the three-dimensional image observation mode; and therefore, the visual projection effect isguaranteed, the browsing experience is improved and the three-dimensional model capable of showing a real and stereoscopic projection effect is provided.

The invention relates to a simulation test platform system for researching driving behaviors, which can provide a vehicle environment and driving functions which are completely consistent with the actual driving for drivers, ensures the driving operation and the authenticity of vehicle data acquisition, and ensures the basic simulation of the indoor use of a test vehicle and the feedback of road conditions to the driving so as to provide a traffic visual simulation environment with high immersion for the drivers. The simulation test platform system comprises a driving test vehicle, a driver information acquisition system, a vehicle information acquisition and processing system, a traffic simulation visual driving module, a visual projection system, a visual simulation and a road traffic scene modeling system, a road driving resistance simulation system and a system integration module, wherein the driving test vehicle is connected with the vehicle information acquisition and processingsystem, and the real-time communication exchange and data feedback between the vehicle information acquisition and processing system and the traffic simulation visual driving module are carried out through the system integration module. The simulation test platform system is characterized in that the driving test vehicle is of a real mini bus, and the steering mechanism of the mini bus is disconnected.
