A superimposition device of virtual guiding indication and reality image includes at least an image capturing device, a processor, a graphic processing unit (GPU), and a display device. The image capturing device captures reality image including instant scene. The processor receives the reality image and obtains height variation information. The GPU performs image correction processing on the reality image to obtain corrected image, generates updated transformation matrix according to the height variation information, and performs inverse perspective projection transformation by using the updated transformation matrix to generate bird's-eye view image of the corrected image and superimposes virtual guiding indication on the bird's-eye view image and performs perspective projection transformation on the bird's-eye view image to transform the bird's-eye view image into three-dimensional (3D) navigation image which includes the guiding indication. The display device displays the 3D navigation image which superimposes the virtual guiding indication into the reality image.

A wide-angle lens calibration system is provided, which may include a rotation unit, an image input unit, and a processing unit. A lens to be calibrated may be disposed on the rotation unit; the rotation direction of the rotation unit may be parallel to the horizontal direction; the optical axis center of the lens may be aligned with a reference object. The image input unit may receive images from the lens. The processing unit may control the rotation unit to rotate and analysis the images received from the lens. The processing unit may execute a distortion calibration process, wherein the processing unit may continuously rotate the rotation unit by a predetermined angle and then record the distance between the position of the reference object in the image and the optical axis center and a total rotation angle after each rotation so as to establish a distortion calibration model.

Wide-angle lens calibration system and method thereof

An image conversion method is provided. An image of a calibration reference pattern is captured. A plurality of first and a plurality of second characteristic patterns of the calibration reference pattern are identified. Coordinates of the first and second characteristic patterns in a first view angle coordinate system are obtained, and coordinates of the first and second characteristic patterns in a second view angle coordinate system are obtained, to obtain a coordinate conversion relationship between the first and second view angle coordinate systems. An input image is converted to an output image according to the coordinate conversion relationship.

A cross-layer rate adaptation mechanism for wireless local area network (WLAN) can obtain the channel state by calculating the E/Nratio of ACK frame transmitted from the receiver side. The mechanism determines the transmission rate of the next frame by referring to a predefined reduced mode table. When receiving an ACK frame fails, the mechanism can automatically lower the transmitting rate of the next transmission. Therefore, the method can reduce the damage to the system when ACK frame failure happens.
