请教：GOOGLE的街景是怎么做的？
就是那个地图上的3D street view。 我想绕我自己的房子四周走一圈然后来个360的
view，容易吗？是不是只需要一个好一点的照相机？
谢谢。

I am working on a role mining project，the data size is not really very big
，but it's a little bit challenging because the customer doesn't have a very
clear picture on the end goal -- a "figure this mess out and surprise us"
kind of situation. So any input would be much appreciated!
*The Problem:
We have a very complex data system on mainframes, RBAC (role-based-access-
control) has morphed into a mess over the past decades.
Access control components include: datasets, special commands that can be
run over the datasets, privileges, system userIDs, system groups, employee
IDs, employee groups.
Joining all the access control settings together into an access matrix is
trivia, the end result is approximately 10,000 x 5000.
In general, the principle of least privilege needs to be enforced.
The basic goal is to optimize the RBAC settings.
*The Challenge:
End user doesn't really know exactly what they want, however this needs a
lots of interactions with them.
*Some of my thoughts:
1. Identify the duplicate and redundant access groups as candidates for
removal.
2. Identify the users with unusual privilege settings for customer's review.
3. Based on the current privileges, identify a global default role for all
the users.
4. Based on the current privileges, identify a departmental default roles.
，but it's a little bit challenging because the customer doesn't have a very
clear picture on the end goal -- a "figure this mess out and surprise us"
kind of situation. So any input would be much appreciated!

就是照相机找的，google那种车上面顶一个球，里面有8个照相机，回来拼一下就有360
度的全景图像了。

Do you look at user's behavior history to decide if he needs certain
privilege?

Nope, not available right now.
It would be the next step, and is quite operation-oriented. They will
monitor user's activities and report long inactivities to mangers for review.

这里有谁能做吗？或者知道那里能买到设备，什么设备和软件，来做吗？多谢。

many point and shoot cameras come with such software already. So seems
pretty easy. Of course, it would be more challenging to make highly
professional pictures.

不确定google怎么做的,但是很多年前(12年前好了),cool3d?忘了,类似的软件就可以辅
助把几张照片拼起来了.技术应该类似.
