I have to calculate area or length of objects in the frame.
As I use the 2d camera, the camera's distance can not be found.
In this case, I am planning to attract a continuous (X CM) line in the previous ground, where its length is known to the CM / M.
Please find attachments for a sample input image (yellow line is a constant line)
Consider that a person or object is standing in front of a wall, where the constant line drawn < / Strong>.
What is the method to calculate the distance of other objects with reference to the continuous line?
First of all, this is not a line. This parcel is a non-physical line in the area of pixel parcel Both the length and the length of the images are the natural unit pixels of the measurement units of length are both non-physical and assumptions are required.
Secondly, you can convert thresholds to 2-D conversions, it uses 2D conversion, it can allow some faster, more accurate measurement in images. Peak intensity will tell you something about length or area You can use line-amount and column yoga very quickly to get the idea of length. This helps to combine images with pixel-axes in your image. You can test different rotation for the use of annexic changes.
