The invention relates to an aerospace craft thermal protection component testing device, and the device comprises an examination cabin, a camera shooting unit, a light emitting unit, a temperature measuring unit, a sliding rail support, a sliding rail support and a control unit. The control unit is used for controlling a heating unit to heat a thermal protection component. When the thermal protection part is heated, the light emitting unit is controlled to emit light, the camera shooting unit is controlled to collect images, and the temperature measuring unit is controlled to collect the single-point reference temperature of a preset reference point of the thermal protection part; the image acquired by each camera component is processed to obtain a spliced image which is a complete surfaceimage of the thermal protection component; a displacement field and a strain field of the thermal protection component are determined by using the spliced image; and a temperature field is determinedby using the spliced image and the single-point reference temperature. According to the invention, the images of the thermal protection device are shot through the plurality of camera assemblies, theimage resolution can be improved, and the displacement field, the strain field and the temperature field of the thermal protection device are determined, thereby obtaining an accurate test result.
