What is the difference between a multispectral camera and a hyperspectral camera?

Multispectral camera and hyperspectral camera are two different imaging devices, which have different advantages and characteristics in applications. Here are the differences between them:

1. Different spectral resolution

Multispectral cameras have a high image resolution, usually between 2-8 million pixels, and a low spectral resolution, generally 30-480 bands, which can provide a certain range of spectral information, but can not distinguish smaller spectral information in detail. The hyperspectral camera has a very high spectral resolution, usually between 1-10 bands, and can distinguish smaller spectral information in detail, but its image resolution is lower, generally less than 4 million.

2. The amount of information obtained varies

Multispectral cameras can only obtain a certain range of spectral information, while hyperspectral cameras can obtain more detailed spectral information. This makes hyperspectral cameras have a wide range of applications in many fields, such as geological exploration, food safety, environmental monitoring and so on.

3. Different application scenarios

Multi-spectral camera is suitable for fast and wide range of ground object reflection spectrum detection, mainly used in agriculture, land resources survey, forest survey, environmental monitoring, mapping, public security system and other fields. The hyperspectral camera is suitable for detecting the reflection spectrum of ground objects in a small range and with high precision, which is mainly used in geological survey, environmental monitoring, food industry, biology, criminal investigation and other fields.

4. Prices vary

Multispectral cameras are relatively inexpensive, while hyperspectral cameras are more expensive.

To sum up, there are some differences between multispectral cameras and hyperspectral cameras in application scenarios, information acquisition, spectral resolution and price. When selecting the device to use, you need to select the device based on actual requirements.
