这是因为ZED新版升级了固件，如果之前在tx2下使用正常，新zed不能使用
 
解决方法：

参考：

https://github.com/stereolabs/ ... es/63
https://github.com/stereolabs/zed-examples/issues/53
 
通过降低固件版本的方法可以解决：
 
在linux或windows 10下安装最新版本的SDK 2.4.1 ,可以忽略安装cuda以及其他不支持的，继续安装完成。
连接zed，得到的画面是很差的，没有关系
选择firmware，update，选择对应的1142固件，确认更新。
完成之后，重插，则能正常使用。
