This paper summarized the research status, imaging model, systems calibration, distortion correction, and panoramic expansion of panoramic vision systems, pointed out the existing problems and put forward the prospect of future research. According to the research status of panoramic vision systems, a panoramic vision system with single viewpoint of refraction and reflection is designed. The systems had the characteristics of fast acquisition, low manufacturing cost, fixed single-view imaging, integrated imaging, and automatic switching depth of field. Based on these systems, an improved nonlinear optimization polynomial fitting method is proposed to calibrate the monocular HOVS, and the binocular HOVS is calibrated with the Aruco label. This method not only improves the robustness of the calibration results, but also simplifies the calibration process. Finally, a real-time method of panoramic map of multi-function vehicle based on vcam is proposed.

We have demonstrated the feasibility of ferroelectric ceramics micro power generator (MPG) supplying low power dissipation integrate circuit (IC) chip basing on Pb(Zr,Sn,Ti)O₃ (tin-modified and niobium-modified PZT95/5) phase transition under shock wave compression. MPG provided micro-pulse-power with transferred energy up to 1.60mJ and with low voltage pulse amplitude 51.8V. We demonstrated experimentally that the MPG-capacitor system can perform as an IC-chip micro-power-sources supplying circuit. A methodology was developed for theory analysis of the MPG-capacitor system. The experimental results were in a good agreement with the theory analysis results.

We demonstrated both experimentally and in theory analysis and calculation that the PSZT ferroelectric ceramic generator system can perform as a micro power supplying source for IC chip. The ceramic phase transition under transverse shock wave compression can charge external storage capacitor. The ferroelectric micro pulsed power system is capable of generating low output voltage pulses with amplitudes 50.3 V and with transferred energy 1.12 mJ, and supplying IC chip with micro power sources. We developed the methodology for theory analysis and experimental operation of the ferroelectric generator. The experimental results were in good agreement with the theory analysis.
