RTOS/TDA2P-ACD: AR0220+UB953 Configuration

Abhay Sorte

Part Number: TDA2P-ACD

Tool/software: TI-RTOS

Hello,

Currently I am referring to ar0143 sensor code available in Vision SDK 03.03 at "vision_sdk\apps\src\rtos\iss\src\sensor\ar0143".

In file "iss_sensor_ar0143.c", there is a lookup table in "glbceWdrCfg_ar0143" array with different value. For our AR0220 sensor how can I create similar WDR table.

How to decide what values need to be added in this LUT ?

Abhay

Hi Abhay,

You will have to tune for the sensor, please check \vision_sdk\docs\TrainingSlides\TDA3xISP.pdf

Hi Abhay,

This GLBCE WDR config is not really for WDR merge mode, it is only used for single pass mode.. This requires to be tuned for the sensor.
Btw, why do you want to use this module?

Hi Sujith,
Thanks, I will look into it and get back to you if I have any doubts.

Hi Brijesh,
Actually I am new to this sensor related stuff. I have a brand new sensor AR0220 with me for which I have to add support in Vision SDK for using it in ISS usecase. So I am referring to already available sensor files (ar0143 & ar0140) in Vision SDK to understand how things are done.

Abhay,

Is this AR0220 Bayer or RCCB sensor?

Hi Brijesh,

In the datasheet of Ar0220 sensor I found the following information,

Multiple CFA Options including Bayer (RGB), RCCC and RCCB

Also I have attached the image of our ar0220 camera sensor for your reference.

Abhay,

It is not clear from the board. Please check with your sensor board manufacturer.

Hi Brijesh,

From what I have understood from the AR0220 datasheet, there is register named CFA_TYPE which we need to read in order get the CFA type (Bayer RGB, Monochrome, RCCB, RCCC).

Abhay,

ok, read this register and figure out what kind of sensor it is.

Hi,

By default it is set to Bayer (RGB) . This register is a R/W.

Abhay,

ok, you could first try capturing raw bayer data and see if it looks ok.
AR0220 sensor is not supported in the Vision SDK, so there is no tuning database for this sensor. Sensor requires to be tuned to get good quality output from ISP.

Hello Brijesh,

As we are running different thread to sort out the sensor issue, I will close this thread.
Thanks for your support.
