TDA4VM: Fisheye to rectilinear conversion

Hi Chaitanya,

Yes, LDC can be used for this conversion, provided the input LUT is correct. Please use DCC tool to first validate your LUT and generate DCC binary that can be used on the target. The other option is to convert this LUT in binary format and directly use in the usecase. Please refer to single camera usecase to check how to do this.

Brijesh

Hi Brijesh,

Thanks for the prompt response.

Do I need to raise the request for DCC tool? If so, could you please share me the link respective to that.

In the single cam application, the extension of lut file was .h format but the values inside were in hexadecimal format. You need me to modify my LUT values into hexadecimal and use that file in application, right?

And I'm targeting a 4camera application. Following above method used in single cam will help me in a single cam application, how can I change LUT file for each camera in the runtime.

Could you kindly assist me or provide suggestions on how to proceed?

Best Regards,

Yes, that's correct. You need convert LUT into hex format. DCC tool can help here also.

You can use TIVX_VPAC_LDC_CMD_SET_LDC_DCC_PARAMS to change LDC DCC parameters runtime for each camera.

Hi,

Thank you. The link is open and I raised the request for the access.

Could you please let me know how many days it may take approximately to get an update as from tomorrow holidays were present.

Chaitanya,

I can't say the number of days to get the update, due to holidays.. It will be updated as soon as one of the approver is available. 

Meanwhile you can convert your Lut in binary format, then into header file and then you can use it in the single camera application to check the output.

Sure, I'm already working on this on the other end.

Your access has been granted.

Hi Gang,

In the process of executing the DCCSetup.exe file, after clicking Finish button, facing a error.

Please find the following image for the same.

Could this error be related to a different dependency or system security settings?
