This module provides a NodeJS binding to the Evocortex Libirimager SDK. The direct binding allows to get images from Optris cameras using NodeJS. For any further information about the SDK and the functions available in the API please refers to the Evocortex documentation.
Under development
- Download the irDirectSDK from the Evocortex website
- Install the package:
npm install https://github.com/FiloCara/node-optris.git
| direct binding name | node-optris name | description |
|---|---|---|
| evo_irimager_usb_init | usb_init | Initializes an IRImager instance connected to this computer via USB |
| evo_irimager_usb_init | tcp_init | Initializes the TCP connection to the daemon process (non-blocking) |
| evo_irimager_terminate | terminate | Disconnects the camera, either connected via USB or TCP |
| evo_irimager_get_thermal_image_size | get_thermal_image_size | Accessor to image width and height |
| evo_irimager_get_palette_image_size | get_palette_image_size | Accessor to width and height of false color coded palette image |
| evo_irimager_get_thermal_image | get_thermal_image | Accessor to thermal image by reference, Conversion to temperature values are to be performed as follows: t = ((double)data[x] - 1000.0) / 10.0 |
| evo_irimager_get_palette_image | get_palette_image | Accessor to an RGB palette image by reference |
| evo_irimager_get_thermal_palette_image | get_thermal_palette_image | Accessor to an RGB palette image and a thermal image by reference |
| evo_irimager_set_palette | set_palette | Set RGB palette |
| evo_irimager_set_shutter_mode | set_shutter_mode | Sets shutter flag control mode (0:manual, 1:auto) |
| evo_irimager_trigger_shutter_flag | trigger_shutter_flag | Forces a shutter flag cycle |
| evo_irimager_daemon_launch | daemon_launch | Launch TCP daemon |
| evo_irimager_daemon_is_running | daemon_is_running | Check whether daemon is already running |
| evo_irimager_daemon_kill | daemon_kill | Kill TCP daemon |
