2Inspection Equipment Central Control System

Central control system of the smartphone inspection equipment:

It connects to the phone app, schedules PLC hardware and controls cameras, lighting and audio equipment. It allocates CPU resources to compute camera and screen data - sharpness, color uniformity, and the presence of bright/dark spots or dead lines - and to analyse earpiece and speaker volume and noise. It is a multi-threaded, high-performance communication computing framework.

3Phone lens dark-spot anomaly recognition

For camera lens quality analysis of second-hand phones, multi-layer algorithm recognition and screening greatly improve the detection rate for faint dark spots, raised half-spots, black dots, dead lines and other lens anomalies, raising the quality inspection efficiency of recycling platforms.

4Resolution Analysis

1. Rear camera telephoto resolution

2. Rear camera close-focus resolution

3. Front camera resolution

4. Front camera shading

5Screen Analysis

1. Screen brightness uniformity

2. Screen color uniformity

3. Screen color temperature

Screen dead pixels, bright spots, dead lines, stripes, stains, dark blobs, light leakage, light bleed and burrs
