not simple

A possible extension method but it is NOT free.

Lauch extension - Processing Image CV (Computer Vision applied to images AI).

We present the first CV (Computer Vision) image processing extension, which covers the following algorithms: *Count Objets inside image. *Find Contour with Sobel algorithm (Processing Image Countour). *Choose Color to convert image *Comparate Images *Convert to Array Binary *Convert to Gray *Convert to Sepia *Convert to White-Black *Create Mirror Image *Cretae Random Image *Apply Gaussian algorithm in image *Apply Median Filter in image * *Resize Image *Features Image *Copy Image. …

**Using Blocks (free) **
Here is a discussion about using Blocks and the camera to estimate number, size and distance between objects that you might find the number of objects in a photo. It won't count automatically but it might provide some ideas for you to adapt.

Use camera (photo) to measure distances ( and area)

Hi I have an idea and I don't know how to do it with App inventor I want to measure distances by taking pictures with camera, in example, I will take photos like in this uploaded image, the distance of the blue ligne is known, and I ask the app for detecting and measuring the red ones. Can I do it? [antibiogramme]
