In order to reduce the demand of traditional desktop virtual experiment system for the site and equipment, and solve the shortage of the illuminance meter metrology instructional resources, a illuminance meter virtual experiment program based on Smart Handheld Devices (SHD) was designed and implemented to meet the teaching needs. This program took SHD as the carrier and adopted MultiGen Creator software for real-time scene modeling. The program, Which had been completed interaction and edit of the established 3D model and scene by C# scripting language, was developed on Unity 3D flat. Finally, it realized the augmented reality function by Vuforia software. The experiment shows that the program optimizes the digital resources and meet the needs of illuminance meter metrology teaching.
