全景影像问题分析与优化

Analysis and Optimization of Panoramic Image

本文针对低温冷车启动车辆,偶发360全景系统四路摄像头黑屏的现象,对全景组成系统、影像检测过程以及摄像头芯片进行分析,发现低温时,通过示波器对摄像头上电电流、电压进行监控,最终确认是由于摄像头电流过大导致问题所在,并给出优化方案。

This paper analyzes the panoramic composition system,image detection process and camera chip according to the phenomenon of four-way camera black screen of 360 panoramic system when the vehicle is started at low temperature.It is found that the power on current and voltage of the camera are monitored by the oscilloscope at low temperature.Finally,it is confirmed that the problem is caused by the excessive current of the camera,and the optimization scheme is given.
