When I use Matlab coder，This problem occurs，“Undefined function or variable 'outputLimits'.”

system：windows11 22H2

matlab version：R2022b

When I use Matlab coder，This problem occurs，“Undefined function or variable 'outputLimits'.”，I'm running “Create360BirdsEyeViewImageAroundAVehicleExample”，All M code is ok and normal running，but when I use Matlab coder generate code，An error occurred，as mentioned above，Undefined function or variable 'outputLimits。

In R2021b, anything is ok.

Discover through search(Find output spatial limits given input spatial limits - MATLAB outputLimits - MathWorks 中国),outputLimits()function have some changes in R2022b,But I don't know whether it has anything to do with generating code.

Hope to get help, thank you.

Thank you for reporting this issue. This issue is a bug in the code generation part of the example.

As an interim workaround, please use the helperRegisterImages.m and helperGenerateBirdsEyeViewProject.prj files for code generation of this example from the attached zip file.

Can you check if you have Image Processing Toolbox installed? outputLimits belongs to that toolbox, so if you don't have it, the function would not be available on your computer.

After my inspection, this toolkit（ Image Processing Toolbox） is installed, see the following picture. Moreover, the M code can run normally, just because there is an error in the generated code. You have to run this example in R2022b. Is there a problem? Could you repeat the question, please.

I just noticed the time. You have already made an answer, but I just saw it today. I'm really sorry. Thank you for answering my questions after work, and thank you for your efforts. But my problem has not been solved yet. If you can, I hope you can repeat the problem to see if the same problem exists. Thank you again and hope to receive your reply as soon as possible. thank you.

I use two computers, which can reproduce this problem. I don't know if it is a bug.
