Small Windows app based on QT5 / OpenCV for use with a USB camera

Short description:

A small Windows app (based on QT5 and OpenCV) that displays the video stream of a USB camera, along with two calibratable lines as an overlay. The calibration is done "manually" with the help of markers.

The goal the app is to check objects for their horizontal and vertical orientation.

Program interface

The required functional elements (functional description below) are:

- Functional in fullscreen / smaller size

- Exit button

- Camera initialization / connection

- Calibration button

- Vertical and horizontal red line

- Adjustment of horizontal / vertical lines (up / down arrows)

Fullscreen / smaller size

The GUI should make it possible to display the program interface in fullscreen as well as in reduced form "reasonable", while maintaining the basic layout.

Exit button

Starts simple exit dialog.

Camera initialization / connection

Dialog for selecting and connecting the connected USB camera.

Calibration button

With the help of two markers (which are clearly recognizable/recognized by the camera and located on a horizontal line), the vertical line is calibrated here. On this basis, then the orientation of the vertical line is determined.

Adjustment of the horizontal / vertical lines (up / down arrows)

The location of the lines (not their orientation relative to camera image) must be changeable. Arrow up / down or Arrow left / right buttons move the aligned lines in parallel without losing their previously calibrated alignment.


- Save the current view including the lines

- Splitting the representation into a current representation and that of a stored image

- Selection menu / selection mechanism for these two functions

- Automatically check if a camera is connected when starting the program and if necessary start / connect it directly

These functions are not part of this invitation to tender. To ensure that the text has been read and understood, only bidders will be considered, who send me a message with a price range for these functions.

I expect and need a written invoice with VAT.

For questions I am happy to help and now good luck with the offer!
