Da-Lite, the projector screen company has a great calculator here and even includes a brand and model reference.

You could calculate two perpendicular gradients to each image pixel point. If both gradient are small the pixel pertains to a flat region.

A projector simply projects images onto a wall or projection screen. Projectors are typically used to increase the image size for viewing by audiences. Projectors come in a variety of sizes, normally measured in Lumens which is the brightness of the light. This brightness will determine the size the image can project and the distance the projector can be from the screen. Slide projectors use light to project images from 35mm slides. Digital Projectors use light to project images from computers and DVD players.
To add an image in Premiere Pro, import the image file into your project panel, then drag and drop it onto the timeline where you want it to appear in your video. Adjust the size and position as needed using the controls in the program.
3500 ANSI lumens is a measurement of the brightness produced by a projector or display device. It indicates how much light output the device is capable of, which is important for ensuring clear and bright images in various lighting conditions. A higher ANSI lumens value typically means a brighter image.
To calculate the total number of pixels in an image, multiply the width of the image in pixels by the height of the image in pixels. This will give you the total pixel count of the image.
The minimum image convention for this project is to use high-resolution images that are clear and visually appealing.
Projectors over 2000 lumens can illuminate a wall or screen in a well-lit room.
The pixel size formula used to calculate the dimensions of an image is: Image width (in pixels) x Image height (in pixels) Total number of pixels in the image.

To calculate the pixel size of an image, you need to divide the width or height of the image in pixels by the physical size of the image in inches. This will give you the pixel size per inch.
No, a concave lens diverges light rays and cannot project a real image. It will create a virtual image that cannot be projected onto a screen.
