TDA4VM：manual Calibration Tool still can't output ldc_lut.csv

Hi Do-Kyoung Kwon，

thanks for your reply, now I have modified the excel  and could generate the file LENS.BIN  and go to step4  click "run surroud calibration tool" ,but it  is crashed and can't generate CALMAT.BIN，Could you give me some good advice.

the input camera data order is front,right，rear，left。

the calib chart size like this,

the corner points choose like this， and every board’s corner points order is start from left-top and move clockwise.

when "run surroud calibration tool" the process crashed, in windows system log we can see that  

Why did you choose corners of white square, not outer corners of black square? Not sure if this is related with this crash. But you have to choose the outer corners of black squares.

Yes,I checked  the use_guide doc and  I need to choose the outer corners of black squares.Will the inner corner points be detected in the code?

I use PS to Increase Contrast ratio  of  image like this  but still crash.

Please share original 4 input images.

this is my original camera data

cameradata.rar

Can you also share  ldc_lut.csv that you created?

Yes,this is the   ldc_lut.csv

ldc_lut.csv

It didn't crash for me. But SRV output images doesn't look quite correct (Please see the below image). I guess chart dimension is not correct. Anyway, it didn't crash in my test. Please make sure that CAM1 ~ CAM4 are front, right, rear and left images, respectively. 

the camera data‘s order has no problem,Is you set chart dimension like the below image?

Although I could't generate the CALMAT.BIN,according to CALMAT.BIN's format, I Generated CALMAT.BIIN using our algorithm.

Here is  my CALMAT.BIN.Could you input this CALMAT.BIN to your matlab process and run "Test Calibration Tool" show me the stitch image?

CALMAT.rar

 I think your SRV output images  looks is normal ，but  we need to adjust the Fusion area. 

Here is we use our algorithm generated the front-rear stitch image,left-right stitch image and stich image with fusion .We can see that single camera display is the same as you，and   stich image with Fusion is normal.

So if you use our CALMAT.BIN to output image is same with yours,  we want to know how to adjust the   fusion area ,especially the   fusion area of bowl. thank you!

Unfortunately, the calibration tool does not read CALMAT.bin from a file. CALMAT.bin should be created first to test.

I modified codes to read your CALMAT.bin from a file. As shown below,  output is similar to my previous result. 

Thank you very much for your reply！it's very helpful to me。
