Title: Environment mapping method and apparatus
Inventor: REN QILIN
IPC: G06T7/521
Filed: 2019-01-24
Abstract: Disclosed is an environment mapping method, comprising the following steps: step one, dividing a sphere into three parts; step two, setting the size of a map; and step three, respectively mapping a lateral face part and a top face/a bottom face to a texture coordinate system by different texture coordinate mapping methods. According to the present invention, cylindrical projection which has higher fidelity and is simple in operation is used within an approximate vertical visual scope of human eyes, and due to the feature of conformal mapping of the cylindrical projection, better effects are obtained when scenes, such as a street scene, are observed. Regarding the treatment of southern and northern domes, in the present invention, the domes are uniformly mapped to rectangular maps as far as possible, and by adjusting the sizes of the rectangular maps of the southern and northern domes, joints between the southern and northern domes and an area near the equator can be removed, and the storage consumption of north and south poles can be reduced. By ensuring the continuity of mapping, the problem of pixel aggregation of the north and south poles in traditional cylindrical mapping is solved.

Abstract: Disclosed in the present invention are a balanced radio frequency power amplifier, a chip and a communication terminal. The radio frequency power amplifier divides, by means of a 90-degree power splitter unit, a radio frequency input signal into two equal-amplitude signals having a phase difference of 90 degrees, the two radio frequency input signals are amplified and then inputted into an adjustable 90-degree power combiner, and the values of a adjustable capacitor and an adjustable resistor in the adjustable 90-degree power combiner are controlled by means of a control unit, so as to synthesize the two radio frequency input signals into one radio frequency input signal when the phase difference and amplitude difference of the two signals at different frequencies are the smallest, and to input the radio frequency input signal into a circuit of the next stage by means of a specific radio frequency transmission path. The balanced radio frequency power amplifier not only increases the maximum linear power of the output, but also reduces the sensitivity to a change in the radio frequency antenna load, thereby supporting functions of mobile high performance user equipment.
