TDA2SX: Bboxes exported by TDA2x are shifted when plotted on PC

dolby Yu

Part Number: TDA2SX

I found that positions drew by Draw2D_drawRect(...) function on TDA2xx are different from positions drew by cv::circle(...) function on PC.

Coordinates used on PC are exported from ObjectDrawLink on TDA2x.

Results on TDA2x

Points (115,276) & (211,258) on 512x512 image

Hi Graviraju

I draw the results on PC accurately with the below code.

int imgWidth = 512, imgHeight = 512;
int offsetX = 32, offsetY = 24;
cv::Mat image = cv::imread("../01.jpg");
cv::resize(image, image, cv::Size(imgWidth, imgHeight));
cv::Rect rect(0, 0, imgWidth - offsetX, imgHeight - offsetY);
cv::Mat imgCrop = image(rect);
cv::resize(imgCrop, imgCrop, cv::Size(imgWidth, imgHeight));
    
cv::circle(imgCrop, cv::Point(marks[0], marks[1]), radius, scalar);
cv::circle(imgCrop, cv::Point(marks[2], marks[3]), radius, scalar);

Thanks for your reply.
