Image Detection

July 18, 2021 - 3:23am #1

I want to overlay 2d images on a box using image target. I tested with an image RGB taken by my mobile phone and Vuforia Engine succeed to detect the box and display the overlay images but when I use an RGB image from a specific camera as an image target, the box becomes undetectable. I have tried to change the parameters of the image like the contrast, the saturation,... but without a result. Could you please help me ? In my final project I have to use the images from the specific camera as an image target.

Hi,

I suspect issue is based on the file size. Refer to the post.Invalid Image Target file format

Where the most relevant info is below

//===================================================

The error message is indicating that the conversion to JPG has rendered the image incompatible with our services. Suggest that you use a tool, such as IrfanView, to review the image's properties to see if it meets our format requirements:

Must be 8- or 24-bit PNG and JPG formats; less than 2 MB in size; JPGs must be RGB or greyscale (no CMYK).

IrfanView can also be used to convert the QR Code into a compatible JPG file.
