For >>parrotMinidroneCompetitionStart, in parrotMinidroneCompetition/Flight Control System (flightControlSystem)/Image Processing System
It comes up with error when applying the Color Space Conversion block for RGB to HSV.
I have tried Data type conversion to ensure the input and output is 'uint8' however it seems to not be picking up port 3. Is this a probelm with the Color Space Conversion block or is there something I am missing?

Hi Jaylene,
I understand that you are getting an error regarding supported data type by Color Space block for R’ G’ B’ to intensity values conversion while using data type of “uint8”.
When the Conversion parameter is R'G'B' to HSV, the Data types that are supported in the block are just single-precision, and double precision. For detailed information, you can refer to the documentation of “Color - Space Conversion block” below:
https://in.mathworks.com/help/vision/ref/colorspaceconversion.html?searchHighlight=color%20space%20conversion&s_tid=srchtitle_support_results_2_color%2520space%2520conversion#mw_e0e8e41f-6a60-4a15-a18a-4b087c311296:~:text=int8%20%7C%20uint8-,H%20%E2%80%94%20Hue%20component%20of%20image%0Amatrix,Data%20Types%3A%20single%20%7C%20double,-X%20%E2%80%94%20X
Setting the R’, G’ and B’ input to single or double will resolve the issue and the block will start working.
