55014023a9123006d1e042187569757 61b6dd42fbce38b86bb431bee5e2037 您好！首先非常感谢您的开源项目 内参标定正常情况下，每一个相机图片过宽。与parameter_setting的哪个参数有关？ doc中说明每个像素代表一厘米，但是对于小车1cm>>1piexel，请问如何换算？

您好，4个usb摄像头 同时插入四个摄像头，四个都可以检测到，但是不工作，请问如何降低带宽，让四个摄像头同时工作 ？ 我用的是jetson nx设备

相机接受一个 resolution 参数。标定以后的 yaml 文件里面会记录这个分辨率。

doc中说明每个像素代表一厘米，但是对于小车1cm>>1piexel，请问如何换算？

这个根据你的标定板尺寸，视野范围，相应比例换算标志点的像素位置即可。比如你希望视野是 100cm x 100cm，front 相机投影后是 400x200像素，那么你的左上角 (10cm, 10cm) 位置的点就应该对应图像中左上角的 (40, 20) 像素。

您好 请问在测试demo时出现一下情况： Traceback (most recent call last): File "/home/rwb/Downloads/surround-view-system-introduction-master/surround_view/birdview.py", line 329, in run self.make_luminance_balance().stitch_all_parts() File "/home/rwb/Downloads/surround-view-system-introduction-master/surround_view/birdview.py", line 225, in make_luminance_balance a1 = utils.mean_luminance_ratio(RII(Rb), FII(Fb), m2) File "/home/rwb/Downloads/surround-view-system-introduction-master/surround_view/utils.py", line 56, in mean_luminance_ratio return get_mean_statistisc(grayA, mask) / get_mean_statistisc(grayB, mask) File "/home/rwb/Downloads/surround-view-system-introduction-master/surround_view/utils.py", line 52, in get_mean_statistisc return np.sum(gray * mask) ValueError: operands could not be broadcast together with shapes (500,1600) (550,500) Aborted (core dumped) mask和weight图片的尺寸一致
