Hi Li Cookie,
When using the “objectDetection” object, the “ObjectAttributes” property must be specified as a scalar structure or a cell array containing a scalar structure for code generation. This requirement ensures compatibility with MATLAB Coder.
To resolve your error please ensure to pass “ObjectAttributes” as a struct while creating the “objectDetection” object. Refer to the following documentation example to understand how to do so - https://www.mathworks.com/help/driving/ref/objectdetection.html#:~:text=struct(%27myProperty%27%2C2)
